Description
Marshall Fire Community Rebuilding BuildSmart Energy Efficiency Workshop, April 11, 2022
A
Welcome
everyone:
my
name
is
ron
flax,
I'm
the
deputy
director
for
community
planning
and
permitting
in
charge
of
building
and
permitting,
as
well
as
the
chief
building
official
for
the
county,
thanks
for
thanks
for
joining
us
this
evening.
The
goal
this
evening
is
to
to
spend
some
time
specifically
talking
about
the
boulder
county
energy
codes.
A
A
I
think
we'll
we
have.
We
have
a
quite
a
bit
of
content
to
cover
tonight
and
we're
gonna
do
our
best
to
address
many
of
the
questions
that
we've
gotten
so
far
about
this
topic
and
then,
at
the
end
of
the
presentation,
we'll
have
a
series
of
additional
resources
for
folks
for
for
additional
questions
that
maybe
we
we
didn't
get
into
this
evening,
but
to
the
best
of
our
ability.
I'd
like
this
to
be
as
much
in
this
format
allows
a
bit
of
a
conversation.
A
A
Just
to
give
you
just
a
little
bit
of
a
brief
background
about
myself,
so
I
am
the
chief
building
official
for
the
county.
My
my
background
is
in
fact,
with
with
construction
and
home
building,
so
I
I
did
start.
I
did
work
for
years
as
a
part
of
a
production
home
building
company.
I
have
a
degree
in
architecture
and
worked
in
that
field
for
quite
a
few
years.
I
also
am
a
hersh.
B
B
So
I'm
going
to
take
two
angles
on
that.
The
first
is,
you
know
what
makes
up
a
high
performance
and
predominantly
we're
talking
about
high
performance
windows,
high
insulation,
high
r
value
insulation,
heat
recovery,
ventilation
having
an
airtight
envelope
around
your
building
with
no
thermal
bridges
and
thermal
bridges
are
where
you
have
a
medium
that
allows
heat
to
to
transfer.
I
think
a
2x4
in
between
your
fiberglass
insulation,
batting
and
then
you
know
taking
advantage
of
the
solar
orientation
and
shading.
B
So,
broadly
speaking,
that's
you
know
some
of
the
elements
that
make
up
high
performance
homes
in
terms
of
energy
efficiency
codes.
Broadly
speaking,
what
makes
up
an
electrified
home?
You
know
it
could
be
any
combination
of
these
things,
not
all
of
them
necessarily
all
at
the
same
time,
and
I'm
absolutely
not
saying
that
all
of
these
things
are
required.
B
I'm
just
saying
that
this
is
the
universe
of
things
that
we're
talking
about
here
tonight,
so
that's,
rooftop,
solar
or
maybe
you're
purchasing
renewables
from
the
grid.
Maybe
you
have
home
battery
storage,
a
heat
pump,
closed,
dryer,
a
heat
pump,
hot
water,
heater
heat
pump
for
space,
heating
and
cooling
electric
cooking,
whether
that's
electric
resistance
or
induction
electric
vehicle,
electric
vehicle,
car
charging
and
energy
recovery
ventilation,
or
typically,
when
we're
talking
about
electrified
homes.
We're
talking
about
some
of
those
elements.
B
B
B
B
You've
increased
resiliency
during
disasters,
so
you
know,
say
you
had
a
natural
gas
furnace,
that's
great!
If
you
have
natural
gas
service,
but
if
the
electricity
is
not
on
there's
no
power
to
run
the
electronics
and
the
fans
and
that
furnace,
so
you
know
your
natural
gas
furnace,
doesn't
do
you
any
good
without
electricity
and
as
we
saw
in
the
marshall
fire,
electricity
was
restored.
First,
before
natural
gas
was
restored.
B
B
A
D
A
D
B
I
can
read
them,
so
we
have
42
percent
saying
that
they
lost
their
home
or
damage
from
the
fire,
11
or
builders
who
are
familiar
with
build
smart.
Eleven
percent
are
builders
who
are
new
to
build.
Smart
24
are
design
professionals,
architects,
hers,
energy
raiders
are
similar
and
then
11
said
other
okay.
A
Thank
you,
and,
and
you
know,
the
results
of
that
poll
are
not
not
going
to
be
used
for
much
of
anything
other
than
just
help
me
understand
who
who
I'm
speaking
with
at
the
moment.
So
so.
Thank
you.
That's
not!
That's!
Not
if
you
didn't
get
a
chance
to
to
respond.
That's
not
gonna,
that's
not
gonna
have
any
any
impact,
so
I
just
just
trying
to
understand
who
who's
in
the
room
with
us.
So
thank
you
next
slide.
Please,
if
you
would.
A
Zach,
are
you
able
to
excellent
okay,
so,
just
just
by
way
of
background,
what
we're
working
with
in
unincorporated
boulder
county
is
a
set
of
building
code
requirements
that
are
based
on
the
2015
code.
So
this
is
those
the
code
books
you
see
on
the
table.
There
are
the
the
nationally
published
code
books
by
the
international
code
council
and
in
the
center
of
that
table,
is
a
copy
of
the
physical
copy
of
the
boulder
county
amendments
to
that
code.
A
A
A
If
you
have
existing
housing
stock,
often
what
we
find
is,
we
have
have
hers
scores
that
are
well
well
above
100,
so
you
know,
150
170
is
pretty
common
for
many
of
the
existing
home
that
we
have
existing
homes.
We
have
in
our
community,
but
this
is
a
really
primary
tool
that
we
use
in
boulder
county's
energy
code
to
help
us
understand
and
regulate
the
energy
efficiency
of
our
homes.
A
The
the
rating
scale
in
the
rating
system
accounts
for
essentially
all
of
the
energy
that's
used
to
heat
and
cool
a
home.
There
are
assumptions
for
average
homeowners
for
plug
loads.
It's
it's
designed
specifically
to
avoid
being
swayed
by
individual
behavior,
so
some
people,
like
their
homes,
warm
or
some
people
likes
their
homes,
cool
that
is
designed
out
of
this
index.
A
So
it's
designed
to
be
blind
as
to
the
occupant
behavior
and
it's
based
upon
very,
very
large
averages
for
behavior
and
it's
been
certified
by
the
the
national
laboratories
very
carefully
over
over
many
years.
At
this
point,
so
it's
a
very,
very
useful
tool
for
us
to
figure
out
how
to
how
to
how
to
understand
how
efficient
a
home
is.
So
the
way
that
it
works
is
essentially
it's.
A
A
A
This
is
this
is
the
first
sort
of
thing
to
understand
and
when,
when
we
look
at
these
numbers,
so
the
square
footage
that's
shown
on
this
slide,
it's
very
important
to
understand
that
what
we're
talking
about
in
this
life
for
square
footage
is
the
conditioned
floor
area.
So
it's
not
the
same
as
what
you
might
have
been
hearing
about
in
terms
of
residential
floor
area
that
regulates
the
overall
size
of
the
home
on
the
the
planning
side
of
boulder
county.
A
So
what's
what
what
falls
under
the
land
use
code
or
the
article
19
provisions
within
the
land
use
code?
This
slide
is
just
focused
on
energy,
and
so
what
we
care
about
is
this
the
area
of
the
home
that
is
being
heated
or
cooled.
So
so,
essentially
you
can,
you
can
think
of
it
as
the
the
area
of
the
home
beach.
That's
that's!
The
interior
space,
so
when
you
we
measure
essentially
to
the
inside
face
of
the
interior
air
barrier,
which
typically
is
our
our
drywall
or
gypsum
wall
boarding.
A
So
in
the
first
category
for
homes
that
are
up
to
3
500
square
feet,
you
you
have
a
choice.
You
can
either
use
what
we
call
the
prescriptive
path
and
we
have
a
slide
that
talks
a
little
bit
more
about
this
coming
up
a
little
later.
But
the
prescriptive
path
is
a
method
in
the
code
that
tells
you
what
the
minimum
energy
efficiency
is
for
some
of
the
key
components
of
the
home.
So
it
tells
you
what
your
minimum
wall
installation
should
be.
A
A
The
next
box
down
is
what
we
call
the
eri
path.
That's
the
code
language,
but
essentially
the
the
the
that's
the
the
eri
path
counts.
We
we
treat
that
the
same
as
the
hers
path.
So
you'll
see
these
things.
Interchanged,
eri
and
hers
are
in
boulder
county
treated
as
interchangeable
metrics,
but
so
so
you'll
see
in
the
code
in
the
public
code.
It
refers
to
it
as
eri,
but
for
our
purposes
you
can
think
of
that
as
hearse.
A
I'm
hearing
some
some
translation
going
on
there,
okay,
so
hopefully
that
that
makes
a
little
bit
of
sense.
It's
a
little
confusing
and
I
don't
want
to
get
too
deep
in
the
weeds
as
to
why
we
have
these
two
things.
But
but
in
fact
it's
really.
The
her
score
is
how
we
measure
we
regulate
in
in
boulder
county,
and
I
have
a
table
coming
up.
I
think
it's.
The
next
slide
is
the
the
table
so
zach.
A
If
you
could
just
go
forward
for
a
moment
so
I'll
come
back
to
the
slide
we
were
just
at,
but
this
is
a
graphical
index
showing,
as
the
house
gets
bigger,
how
the
hers
targetment
the
the
hers
target,
gets
more
stringent.
So,
as
your
conditioned
floor
is,
is
approaches
5,
000
square
feet,
then
you're
talking
about
a
home
that
has
to
have
a
her
score
of
zero,
whereas
you're
building
a
a
2,
500
square
foot
house,
you
only
need
a
hers
target
of
50..
A
It's
important
to
keep
in
mind
that
as
the
house
gets
bigger,
it
both
gets
harder
to
to
actually
achieve
these
numbers.
But
the
number
the
target
itself
moves
a
bit.
So
if
you
are
building
a
3,
500
square
foot
house,
you
can
see
on
this
chart,
you
need
a
hers
of
40..
That's
that
spot
is
kind
of
an
important
demarcation,
because
if
you
are
just
building
a
house
and
using
energy
efficiency
measures,
so
good
windows,
good
insulation,
you're
air,
sealing
well
you're
putting
in
good
mechanical
systems.
A
A
So
that's
talking
about
things
like
roof-mounted,
pv
or
ground-mounted,
pv
or
perhaps
participation
in
a
community
solar
garden,
but
below
that
number
of
hers,
40
or
above
all
of
that
is
readily
achievable
by
just
building
with
with
good
wall
systems,
good
air
sealing
and
and
so
forth.
So
it's
just
as
you
start
to
plan
your
homes,
it's
important
to
sort
of
think
about
that
a
little
bit
all
right,
zach.
If
we
can
go
back
back
one
slide.
A
We
we
don't
have
very
many
houses
in
in
boulder
county
that
have
been
using
that
third
box
of
passivhaus
lead,
platinum
or
living
building
challenge
as
a
way
to
demonstrate
code
compliance
most
people
choose
the
energy
star
and
the
her
score
as
the
way
to
do
it,
and
part
of
that
is
because
the
documentation
is
very
easy.
It's
straightforward.
A
The
energy
star
program
was
designed
to
be
readily
achievable
by
production,
home
builders
across
the
country.
It
is
a
realistic
set
of
of
requirements
with
very
easily
verifiable
requirements,
and
so
it's
just
easy
to
achieve.
The
the
energy
star
requirement
as
and
to
use
to
demonstrate
your
compliance
with
the
building
code,
even
for
those
projects
that
maybe
are
pursuing
one
of
the
other
additional
certifications,
even
if
they're
doing
that.
Often
they
still
demonstrate
co-compliance
with
the
her
score
and
the
energy
star,
even
if
they
in
fact
are
pursuing
something
more
vigorous.
A
Now,
it's
important
to
make
a
note
of
on
this
slide
that
the
building
code
buildsmart
requires
energy
star
version,
3,
minimum
energy
star
version
1
is
is
about
to
transition
into
the
baseline
version.
So
so
we,
the
energy
star
program,
which
is
regulated
by
the
epa,
the
environmental
protection
agency.
They
have
a
process
for
rolling
out
new
versions
of
energy
star
and
so
essentially,
boulder
county
has
been
accepting
whatever
the
current
version
of
energy
star
is.
A
A
But
the
reality
is
that
that
homes
that
are
built
to
these
standards
did
the
difference
between
energy,
star
version.
3
and
3.2
is
actually
not
that
large,
and
so
it's
it's
not
going
to
be
a
huge
or
heavy
lift
to
get
those
additional
dollars
from
from
excel,
and
I
think
it's
it's
a
very,
very
good
value
for
that.
A
A
But
we
do
have
this
check
in
there
just
to
make
sure
that
that
you're,
yet
you're,
not
just
adding
a
huge
amount
to
pv
to
a
poorly
designed
or
poorly
built
building
envelope,
that
we
get
a
certain
minimum
level
of
efficiency,
which
translates
to
a
certain
minimum
level
of
comfort
and
durability
and
resilience
before
adding
the
pv
and
then
there's
another
requirement.
The
second
box
down,
which
is
the
department
of
energy,
the
doe,
zero
energy
ready
home
certification.
A
So
this
is
a
program
that
is
takes
the
basics
of
the
energy
star
program
and
add
some
additional
requirements
again.
A
program
that
is
readily
achievable,
designed
nationally
to
be
attractive
for
production
home
builders
around
the
country
to
to
make
homes
that
are
more
energy
efficient.
This
also
has
a
lot
of
great
value
to
the
homeowner
if
it
gets
into
a
bit
about
some
of
the
other
durability
and
comfort
features
of
the
home,
it
has
some
pieces
that
really
help
us
with
interior
air
quality
and
water
efficiency.
A
So
again,
a
very
a
very
well
designed
and
readily
achievable
program.
One
piece
to
note
is
that
the
the
excel
rebates
for
the
zero
energy
ready
home
program
are
tied
to
their
version
two
program,
so
that
that
is
a
newer
program
and
again
something
that
you
want
to
just
make
sure
you're
paying
attention
to,
because
it
has
again
some
pretty
generous
funding
from
excel.
A
If
you
achieve
that,
but
you
do
need
to
make
sure
that
you're,
specifying
with
your
design
team
that
you're
looking
to
hit
the
version,
two
certification
and
not
just
the
version,
one
certification
that
is
on
the
market
right
now.
So
if
you
can
go
to
next
slide,
please,
okay
and
just
I'll
just
go
back
to
this
again
that
that
this
is,
you
know,
as
as
the
house
increases,
the
her
score
gets
more
stringent.
So
when
I'm
asked
the
question,
especially
for
bigger
homes,
what's
you
know?
A
What's
the
cost
of
build
smart
and
what's
the
cheapest?
What's
the
best
way
to
reduce
the
cost?
Actually,
making
the
home,
smaller,
even
by
small
amounts,
can
sometimes
have
a
pretty
dramatic
impact
on
on
reducing
the
stringency
of
the
energy
code
and
again
when
you're
looking
at
these
numbers,
we're
talking
about
conditioned
floor
area,
not
total
residential
floor
area.
A
So
if
you
have
an
un,
if
you
have
an
un
unheated
garage
that
doesn't
that
doesn't
count
towards
this,
if
you
have
porch
areas
that
doesn't
count
towards
this
we're
just
looking
at
the
portion
of
the
home,
that
is,
that
is,
is
being
heated
or
cooled.
I
will
bring
attention
to
this.
The
little
note
on
the
bottom
of
this.
A
It's
a
pretty
important
piece
of
this,
and
that
is
that
if
you
have
elements
of
the
home
that
are
fossil
fuel,
that
are
fossil
fuel
consuming
devices
that
are
outside
the
building
envelope
so
outside
the
home,
and
so
we
think
about
things
like
a
pool
or
a
hot
tub
or
a
snow
melt
system,
or
maybe
like
a
patio
heater.
Anything
like
that
where
we
have
something:
that's
that's
a
heating
device
that
is
consuming
fuel,
decorative
fireplaces,
natural
gas,
decorative
fireplaces.
A
All
of
those
things
require
direct
energy
offsets,
so
those
things
are
not
accounted
for
in
the
hers
score,
and
so
there
we
account
for
them
separately.
There's!
No.
If
you
have
a
barbecue
that
doesn't
count,
but
if
you
have
a
decorative
fireplace
that
does
so,
the
idea
is
that
those
additional
energy
consuming
devices
have
to
be
have
to.
You
have
to
offset
those
energy
components
directly.
A
A
A
A
So,
even
though
we
adopted
this
back
in
2015
at
that
point,
it
was
considered
more
aggressive
than
the
15
code,
but
the
nationally
published
code
has
caught
up,
and
so
this
these
numbers
match
match
pretty
closely.
We
do
allow
this
to
be
used,
but
we
do
point
out
that
there
actually
has
to
there
actually
ends
up
being
more
more
restriction
in
terms
of
the
flexibility,
especially
during
the
pro
the
construction
process,
because,
let's
say,
let's
say,
you're
having
trouble
I'll
choose
skylights
for
an
example.
So
this
has
a
skylight.
A
B
So
we
know
one
question
that
comes
up
a
lot
of
course,
particularly
even
the
under
insurance
challenges
that
folks
are
facing.
Is
you
know
how?
How
can
you
find
ways
to
save
money
or
reduce
costs
when
building
your
home?
We
don't
have
all
the
answers
here
tonight,
but
we
want
to
cover
a
couple
specifically
as
they
relate
to
the
energy
use
and
design
of
your
home.
B
So
first
one
is
aligning
your
team
so
having
an
architect
builder
and
subcontractors
that
are
all
aware
and
on
board
with
goals
that
you
want
to
achieve
with
your
rebuild
particularly
around.
You
know
what
is
required
or
what
you
are,
what
certification
you're
trying
to
build
to
that's
really
important.
If
they're,
not
all
aligned
and
don't
all
understand,
then
you
can
have
miscommunication,
and
you
know
things
get
accidentally
cut
out
of
the
build
that
should
have
stayed
etc.
B
B
Having
that
in
mind,
early
on
in
your
design
stage,
can
really
impact
the
cost
effectiveness
of
the
home
that
you're
building
building
a
more
simple
shape
of
a
home,
a
home
with
less
you
know,
a
more
sort
of
boxy
home
with
less
sort
of
architectural
features
and
a
wall
bumped
out
two
feet
here
or
there
not
only
will
save
you,
energy
use
by
having
less
surface
area
to
your
interior
space
area,
but
it
also
reduces
the
construction
complexity.
Costs
having
multifunctional
spaces
also
can
help
reduce
construction
costs
and
excels.
B
B
B
B
So,
first,
looking
at
specifically
the
the
you
know,
the
easiest
comparison
and
easiest
corollary
is
for
homes
that
are
over
3
500
square
feet
under
build
smart,
as
ron
mentioned
they
are
required
to
you
know,
meet
the
prescriptive
path,
usually
going.
Excuse
me
how
prescriptive
pick
one
of
those
two
and
usually
one
of
them
is-
is
meeting
the
energy
star
requirements
as
the
performance
requirement.
B
The
build
smart
requirement
is
version
energy,
star
version.
Three
excel's
requirement
is
energy.
Star
version
3.2.
We
will
give
a
comparison
on
what
the
difference
is
there
in
a
sub-coming
slide
here.
If
for
folks
who
are
going
to
you
know
using
a
passive
house
standard
as
their
needs
of
me,
build
smart
compliance
that
we're
in
you,
the
37
500
standard
and
for
folks
choosing
to
build
to
the
zero
energy
ready
home,
which
is
one
of
the
the
three
options
for
homes
over
5000
square
feet.
B
That
would
get
you
the
12
500
and
again,
that's
version.
Two
would
be
required,
not
version
one.
But
again
we'll
talk
about
that
shortly
and
for
homes
under
3
500
square
feet.
There
is
an
exact
there's,
not
an
exact
corollary
as
clear
in
in
how
the
build
smart
program
is
set
up,
but
obviously
those
homes
are
also
still
eligible
for
all
of
those
in
the
same
incentives.
B
So
I
want
to
talk
about
the
difference
between
energy,
star
version,
3.2
and
zero
energy
ready
homes,
version
two
and
version
one.
The
main
difference
between
those
versions
is
that
the
newer
versions
are
built
on
the
2021
international
energy
conservation
code,
and
here
on
this
slide,
not
trying
to
have
you
digest
everything.
B
But
if
you
look
vertically
down
between
each
of
the
columns
in
the
2021
international
energy
conservation
code
and
below
the
corresponding
column
and
build
smart,
you
will
see
that
frequently
the
build
smart
requirements
are
the
same
or
more
stringent
than
the
2021
requirements,
and
I
want
to
be
clear
that
older
county
is
not
on
the
2021
code.
This
is
merely
a
demonstration
that
the
amended
code
that
boulder
county
is
on
is
quite
similar
to
what
the
requirements
are
of
energy.
B
A
So
so
we've
been
talking
about
these
programs,
and
I
guess
it's
just
it's
going
to
be
a
little
bit
useful
to
to
describe
a
little
bit
more
how
these
things
relate
to
each
other.
So
so
the
first
thing
is,
you
know
the
the
energy
star
program
and,
as
zach
just
pointed
out,
you
know
the
the
energy
star
version.
3.2
is
based
upon
a
newer
baseline
code
and
so
the
idea
of
the
energy
star
program.
A
Is
it
it's
designed
to
push
just
a
little
bit
above
the
baseline
code,
and
so
what
ends
up
happening
is
the
energy
star
program
is
always
supposed
to
be
leading
or
out
ahead
of
the
the
codes
the
nationally
published
codes
by
by
the
international
code
council.
So
what
ends
up
happening?
Is
it
just
gradually
gets
more
and
more
efficient
in
a
leading
way,
but
the
other
piece
of
this
that
I
think
is
really
provides
a
great
deal
of
value
to
the
consumer.
A
Is
that
there's
there's
some
additional
checks
and
verifications
built
into
this
program?
So
so,
for
instance,
if
you
are,
are
building
a
home
to
energy
star,
not
only
do
they
give
you
some
guidance
on
the
let's
say
the
the
efficiency
and
power
consumption
of
the
the
bath
fans,
but
they
actually
also
verify
when
the
raider
tests
that
those
bad
fans
in
fact
are
doing
what
they're
supposed
to
do
now.
A
So
so
the
the
baseline
code
verifies
those
things
are
there,
but
but
we
don't
have
a
mechanism
to
actually
you
know
test
those
things
the
as
we
move
into
the
energy
star
program
and
then,
even
more
so
with
the
zero
energy
ready
home
program.
There
are
additional
checks
and
verifications
and
credentialing
of
the
the
people
who
are
installing
this
equipment
so
and
what
we
find
is
when
we
do
that.
A
Additional
verification
we
do
find
times
when
things
are
were
thought
to
have
been
installed
correctly,
but
but
just
weren't,
and
so
the
the
additional
verification
actually
provides
a
great
deal
of
long-term
value
for
the
owners
of
these
buildings,
and
it
was
designed
with
that
in
mind.
It
was
designed
to
to
come
up
with
a
way
on
a
national
level
again.
A
As
we
move
into
the
the
zero
energy
ready
home
program
that
that
list
starts
to
to
expand
even
even
further-
and
we
start
to
we
start
to
get
into
air
quality
issues
and
making
sure
that,
like,
for
instance,
there's
minimum
requirements
for
the
the,
if
you
have
a
whole
house,
forced
air
system,
there's
a
requirements
that
talks
about
what
minimum
filter
efficiency
you
have
in
the
house
and
that's
really
actually
quite
important.
When
we
look
at
some
of
the
changes
that
we're
seeing
to
to
our
our
environment.
A
So,
for
instance,
we
saw
last
summer
are
very,
very
some
very,
very
smoky
periods
last
summer
from
some
of
the
big
fires
that
were
happening
to
the
west
of
us
and
a
home
with
a
better
heating
and
cooling
system.
A
better
ventilation
system
has
the
ability
to
install
better
whole
house
filtration
to
reduce
some
of
those
smoke
particles,
in
a
way
that
you
can't
just
retrofit
on
an
existing
system
that
hasn't
been
designed
for
it.
A
A
And
this
is
just
one
of
many
of
the
sort
of
marketing
campaigns
of
published
by
the
department
of
energy
advertising,
their
zero
energy
ready
home
program,
but
you
can
see
here
it's
a
little
hard
to
make
out,
but
there's
these
green
bars
and
the
blue
bars-
and
that
is
trying
to
help
understand
some
of
the
distinction
between
zero
energy
ready
home
program
and
the
energy
star.
This
slide
is
a
little
bit
dated.
A
I
think
the
baseline
code
has
come
up
quite
a
bit
compared
to
energy
star
and
the
energy
star.
Zero
energy
ready
home
program
gap
is
a
little
smaller
than
it
was
especially
for
for
some
of
the
the
basics
about
durability.
Some
of
those
durability
pieces
have
made
its
way
down
to
other
parts
of
the
code,
since
this
slide
was
put
together.
A
But
it
really
is
designed
by
the
same
group
of
fundamental
group
of
people
and
scientists,
at
our
national
laboratories
and
in
the
private
sector,
who
have
been
pushing
and
understanding
these
codes
for
quite
a
while
now
and
they
really
are
designed
to
integrate
together
and
for
one
to
pick
up
right
exactly
where
the
other
leaves
off
and
in
fact
that's.
One
of
the
reasons
why
these
programs
have
really
gotten
much
much
easier
to
understand
is
that
the
they're
now
integrated
into
one
piece
of
software.
A
So
the
same
software
that
that
an
energy
rater
would
use
to
generate
a
her
score,
can
also
tell
you
where
you
are
regarding
compliance
with
energy
star
or
the
zero
energy
ready
home
program.
Now,
just
one
one
caveat
is
that
it
that
that
software
doesn't
yet
give
us
answers
for
the
the
higher
level
of
performance
that's
being
asked
for
for
the
utility
rebates
for
excel
rebates,
but
that
that's
going
to
be
an
additional
layer
that
the
energy
rater
would
have
to
to
pay
attention
to.
A
And
it's
my
understanding
that
that
later
this
month
there
is
some
specific
training
that's
being
put
together
by
excel.
That's
specifically
targeting
contractors
and
energy
raters
to
help
them
identify
and
understand,
as
you
move
from
the
energy
star
version,
3.0
or
3.1
to
the
3.2.
What
that
actually
means.
A
You
should
get
quite
a
bit
of
the
way
there
and
that
additional
incentive
money
should
more
than
cover
any
incremental
addition
that
you
that
you
have
to
manage.
I
do
want
to.
I
guess
I'll
just
say
this
again
and
I
know
zach
spoke
about
this,
but
it
bears
our
repeating
because
it's
such
an
important
concept
and
that
when
we
talk
about
what
does
it
cost
to
do
these
things?
It's
it's.
A
It's
actually
a
pretty
complicated
question
when
you,
when
you
talk
about
whether
or
not
you
know
compared
to
what
is
really
always
the
question,
so
what
does
it
cost
to
build
a
home
that
meets
these
requirements
versus
some
other
requirements?
The
question
is:
what
what
are
you
really
starting
from?
A
So
if
you
start
approaching
your
design
team
with
the
idea
that
you're
going
to
be
pursuing
energy
star
or
zero
injury
home
certification,
that
understanding
right
off
the
bat
is
gonna
guide
decisions
that
really
maximize
the
benefit
without
as
much
of
an
additional
cost
all
right
next
slide.
Please!
A
So
again,
this
is
just
just
talking
about
maybe
some
of
the
some
of
the
pieces
that
are
most
important
as
we
talk
about
things
like
the
zero
energy
ready
home
program,
so
that
program
does
give
you
a
certain
require
certification
in
what
they
call
their
indoor
air
plus
program,
and
it's
got
some
really
basic
things
that
I
think
everybody
wants
in
their
home.
So
it
talks
about
how
to
make
sure
we're
building
our
house
in
a
way
that
that
prevents
pests
from
getting
into
our
house.
A
How
do
we
make
sure
we're
properly
controlling
moisture,
that's
coming
into
our
house?
How
do
we
make
sure
that
our
if
we
have
any
combustion
devices,
if
I
say
if,
because
more
and
more
people
are
building
without
combustion
devices
in
their
homes?
But
if
we
do,
how
do
we
make
sure
we
we
build
that?
So
it's
safe
for
the
occupants.
How
do
we
make
sure
we're
properly
dealing
with
ventrac
ventilation
and
filtration?
So
these
are
all
things
that
that
people
want
in
their
homes.
A
A
Okay,
so
so
these
are
a
couple
of
slides
and
just-
and
I
don't
expect
anyone
to
to
be
able
to
read
all
the
details
on
these
drawings.
These
are
just
some
slides
that
I
wanted
to
just
help.
People
understand
when
we
talk
about
passive
house
design,
so
there
has
been
a
huge
uptick
lately
locally
with
people,
thinking
about
and
being
interested
in
what
we
call
the
passive
house
design.
A
So
the
passive
house
is
a
certification
program
and
if
you
achieve
certification
with
passive
house
design,
there
is
a
very
generous
incentive
being
provided
by
excel,
but
it
does
require
you
to
think
a
little
bit
differently
about
how
that
home
is
built.
This
is
a
very
useful
design
detail
these.
These
are
just
free
images
that
I
pulled
from
high
performance
building,
supply,
475,
high
performance
building
supply,
and
these
are
just
to
give
people
some
idea
of
what
we're
talking
about.
A
So
these
are
what
you'll
notice
about
this
is
very
thick
walls,
so
these
are
double
stud
walls
insulated
with
a
lot
of
cellulose-
and
this
is
a
very
good,
durable
long,
lasting
energy
efficient
low
carbon
solution.
It's
non-toxic,
it
doesn't
have
a
lot
of
spray,
foam
insulation
or
plastic
foam
insulations
that
might
present
environmental
hazards
or
that
can
become
readily
become
fuel
in
in
a
fire.
A
This
is
a
cellulose-based
system.
It's
really
works
very
very
well.
It
is
a
thicker
wall
than
most
people
are
used
to
building
and
what
we've
been
hearing
is.
People
are
designing
and
building
these
kinds
of
walls
without
much
of
a
price
increase
compared
to
traditional
building.
As
long
as
people
are
designing
up
front
and
keeping
the
architecture
relatively
simple,
the
the
fewer
convoluted
corners
or
complicated
connections
that
you
have
the
easier
it
is
to
pull
this
kind
of
detail
off,
but
it's
a
very
effective
process.
If
you
give
the
next
slide,
please.
A
So
the
the
the
key
thing
about
the
past
values-
the
actual
requirements
are
relatively
simple.
The
achieving
it
is
is
not
is
it
takes,
takes
considerable
care
up
front
in
terms
of
thinking
about
it,
but
also
in
terms
of
the
construction
itself,
but
basically
what
the
overall
passive
house
certification
program
is
talking
about,
trying
to
get
the
space
heating
demands
very,
very
low.
So
that's
where
that
475
comes
from
it's
4.75,
000
btus
per
square
foot
per
year.
A
That
number
probably
doesn't
mean
a
lot
to
a
lot
of
people,
but
it's
a
that's
a
very,
very
tight
envelope.
It's
an
envelope!
That's
tight
enough
that
if,
if,
in
the
winter
time,
there's
a
big
storm
and
knocks
power
out
and
the
house
doesn't
have
any
any
heating
ability,
these
houses
will
coast
on
their
owns
for
for
a
long
time,
they're
very
thermally
protected
and
they
they
do
great,
just
left
to
their
own.
A
They
remain
habitable
comfortable
places
for
much
much
longer
than
what
we
traditionally
see
in
in
homes
that
are
that
are
built
in
boulder
county.
I've
heard
many
stories
about
people
who
have
built
houses
to
these
standards
and
they
become
the
gathering
place
for
the
neighborhood
when
the
power
goes
out.
They
also
are
incredibly
quiet.
A
It's
actually
one
of
the
more
remarkable
features
and-
and
one
of
the
reasons
I
think
fundamentally
so
many
people
who
have
lived
in
a
house
like
this
val,
never
go
back
is
because
the
houses
just
are
very
quiet.
You
don't
hear
the
the
street
noises
in
the
same
way.
You
don't
hear
wind
storms
in
the
same
way.
You
don't
hear
rainstorms
in
the
same
way,
they're
just
very
quiet
homes
and
people
really
seem
to
like
that.
They're
also
very
well
sealed.
A
So
there's
that
.6
air
changes
per
hour
ach
air
changes
per
hour
at
50,
pascals
50
pa.
So
that's
the
blower
door
test.
We
depressurize
the
house
or
pressurize
the
house
and
measure
the
air
leakage
rate
and
they're
very,
very
tight.
These
houses
are
really
airtight
and
that
makes
it
totally
different
in
terms
of
how
they
behave
again
on
a
windy
day
or
when
there's
outdoor
air
pollutants.
A
So
we
we
do
know
that
houses
built
to
these
standards,
who
were
near
the
marshall
fire,
don't
have
anywhere
near
the
problem
with
with
smoke
damage
from
traditional
houses
that
that
allowed
much
higher
leakage
rates.
So
it's
kind
of
a
low
hanging
fruit
because
it
doesn't
take
a
lot
of
extra
money
to
build
a
really
airtight
house.
It
does
take
a
little
bit
of
time
and
a
little
bit
of
care
on
the
part
of
the
designer
to
design
the
wall
system
and
the
contractor
to
build
it.
A
A
I
will
say
that
for
for
the
rebates,
the
rebates
require
full
compliance
with
the
passive
house
standards.
So
this
is
something
that
you
should
keep
in
mind
that,
even
if
you
wish
for
a
passive
house
and
that's
your
target,
you
might
want
to
make
sure
that
you're
also
just
paying
attention
to
how
the
house
scores
and
how
you
can
demonstrate
code
compliance.
A
And
that
worked
great
for
them
and
then
they
they
could
still
pursue
that
that
the
the
high
standard
of
passive
house,
but
if
they,
if
they
didn't
quite
hit
it,
they
weren't
left
out
in
the
cold.
There's
not
a
lot
of
redundancy
in
terms
of
the
energy
modeling
there's
a
little
bit,
but
not
much
all
of
the
passive
house
raiders
that
that
I've
been
in
touch
with
about
this.
A
B
So
we're
nearing
the
end
here
and
we
can
have
more
q
a,
and
we
also
collected
some
questions
at
the
start,
that
we
want
to
make
sure
we
cover
as
well.
But
the
last
thing
we
want
to
go
over
are
a
couple
of
additional
resources,
the
first
being
a
new
website
rebuildingbetter.org.
That
does
not
exist.
Yet,
if
you
go
to
it
right
now,
you
will
see
that
the
domain
there's
nothing
there,
but
we're
working
on
it.
I've
been
working
on
it
all
day.
B
B
Many
of
the
questions
we
got
prior
to
this
event
tonight
through
the
registration
on
you
know,
for
example,
what
questions
to
ask
your
builder
and
architect,
things
like
that.
Those
things
will
all
be
found
on
that
website,
as
well
as
detailed
faqs,
frequently
asked
questions
about
excel's
incentives
and
other
aspects.
B
B
B
You
know
more
details
specifically
on
what
is
a
passive
house
and
my
why
you
might
want
to
consider
it,
and
even
if
you're,
not
building
a
passive
house,
the
you
know
the
principles
apply
to
whatever
home
you're
building.
You
know
the
passivhaus
standard
is
sort
of
the
the
highest
upper
echelon,
but
you
know
the
principles
apply,
whether
you're
building
a
code
minimum
or
a
home
that
would
be
more
high
performance.
A
So
so,
there's
a
lot
of
additional
resources
for
specific
questions
just
to
go
through.
What's
on
on
this
slide
here,
so
the
the
first
couple
of
links
are
directly
to
our
the
boulder
county
building
code
web
page,
so
that
that
first
link
brings
you
to
a
web
page
that
has
all
sorts
of
information
about
our
code.
The
details
of
the
code
as
well
as
links
to
specific
handouts
that
might
go
into
specific
details.
A
The
that
email
address
there,
that
is
a
monitored
email
address,
that
our
plan
review
team
looks
at
every
day,
and
so,
if
you
have,
if
you
or
your
builder,
has
specific
code
related
questions,
that's
that's
probably
one
of
the
fastest
ways
to
to
to
get
detailed
answers.
We
also
have
a
link
here
for
folks
who
want
to
subscribe.
A
So
as
we
have
new
information
or
new
new
details
to
to
discuss
anyone
who
subscribes
to
that
that
subscription
site
will
get
email
updates
that
are
related
to
building
code
updates
and
then
finally,
there's
a
link
there
to
a
free
online
source
for
the
the
nationally
published
codes.
So
when
you
go
to
the
boulder
county
website,
that
is
there's
a
pdf
of
the
the
local
amendments
to
the
building
code,
but
that
is
based
upon
a
much
larger
document.
A
The
mostly
mostly
what
we're
talking
about
is
the
irc,
the
international
residential
code
and
that's
a
very,
very
long
book
that
is
in
the
office
of
every
architect
and
and
most
builders
need
to
need
to
build
to
that
code,
and
it
covers
everything
in
the
code.
Our
local
amendments
just
are
published
and
they
talk
about
places
where
something
in
boulder
county
is
different
than
those
nationally
published
codes.
A
Also
is
my
contact
information,
as
well
as
the
contact
information
for
the
marshall
fire
recovery.
So
if
you
have
a
large,
larger,
broader
question
about
rebuilding
after
the
marshall
fire,
that
marshall
rebuilding
at
boulder
county
dot,
org
is,
is
the
place
to
go
and
that
that
gets
to
the
the
rebuilding
team
and
whatever
your
question
might
be,
we
can
make
sure
we
we
get
you
the
answer
or
at
least
point
you
to
where
those
answers
can
be
found.
B
If
you
have
questions
about
building
a
high
performance
home
reaching
out
to
energy,
smart,
the
contact
information,
there
is
a
great
strategy
if
you
have
questions
or
want
to
find
out
more
about
excel's
incentives,
their
faq
and
additional
resources
is
available
on
their
page
as
well
as
they
have
a.
I
forget
what
they
call
it,
but
they
haven't.
They
have
a
phone
line.
For
you
know,
questions
related
to
excel
related
questions
related
in
marshall
fire.
A
So
we
do
recognize
that
that's
the
baseline
environment,
and
that
makes
all
of
this
really
hard.
I
would
say
that
that
that
said
what
we
have
to
keep
comparing
you
know
the
energy
code
requirements
to
is,
you
know,
what's
what's
the
overall
cost
of
construction,
and
how
can
you
simplify
things
and
we
have
always
known
this
is
not.
This
is
not
new
information,
but
we've
always
known
the
simplest
way
to
reduce
the
cost
of
a
construction
project
is
to
make
it
smaller
and
that
that
remains.
A
That
remains
true
today,
that
that,
by
reducing
the
size
of
the
house
and
reducing
the
complexity
of
a
house,
you
do
bring
down
costs,
and
that
is
that's
been
always
been
true.
But
it's
just.
It
bears
repeating
again,
because,
because
we
are
in
a
situation
where
we
are
seeing
escalating
construction
prices
in
at
an
unfortunate
time,.
B
Prior
to
this
session,
we
got
a
question
on
what
questions.
Should
you
ask
your
your
build
team
as
you're
you're,
picking
a
build
team,
and
I
just
wanted
to
preview
this
section
of
the
rebuilding
better
website?
You
know
some
of
these
questions
on
you
know
how
do
do
they
have
experience
working
with
total
loss
insurance
claim
rebuilds
that
can
really
help
your
process
go
smoother.
C
A
A
Some
of
those
features
are
pretty
low
cost
additions.
So,
for
instance,
we
require
that
would
require
all
class
a
roofing
in
wildfire
zone,
two
class,
a
roofing
does
dominate
the
marketplace.
We
don't
see
much
class
b
proposed
when
you
go
to
any
of
the
biggs
box,
retail
stores
for
home
products,
lowe's
home
depot
and
such
class
a
roofing
materials
dominate
the
market.
So
we
were
just
putting
that
in
the
code,
but
there
were
some
additional
changes
to.
A
So
if
you,
you
would
either
need
to
buy
products
that
are
sold
as
ember
resistant,
roofing
vents
or
there's
also
an
allowance
in
the
code
to
simply
take
a
roofing
vent,
and
you
cover
it
with
a
finer
steel
mesh
that
prevents
wind-borne
embers
from
being
able
to
enter
the
attic
assembly.
There's
also
details
in
there
about
providing
a
three
foot
perimeter
around
the
new
comb
that
is
made
of
non-combustible
materials.
A
So,
for
instance,
if
you
had
a
wooden
fence
on
your
property
that
wooden
fence
couldn't
just
connect
to
the
house,
but
they
would
need
to
be
something
in
between
a
non-combustible
fence
for
the
the
section
immediately
surrounding
the
the
house.
So
a
couple
of
interesting
features
about
that
that
we
think
will
go
a
long
way
towards
preventing
a
similar
catastrophe
from
happening
again.
One
of
the
things
that
is
true
is
that
the
the
that
we
have
a
huge
portion
of
boulder
county
is
surrounded
with
grasslands.
A
You
know
one.
One
of
the
very
unfortunate
lessons
we
learned
is
those
those
is
the
kind
of
hazards
that
those
grasslands
can
present
and
especially
can
present
in
a
climate
that
is
changing
so
historically,
we've
always
had
wintertime
windy
days.
But
what
it
was
unusual
about
about
this
last
winter
was
that
in
september
october
november
december,
we
did
not
have
any
of
our
big
fall.
Snowstorms.
A
Those
snowstorms
not
only
provide
critical
moisture
to
our
grasslands,
to
keep
those
full
fuels
from
be
becoming
quite
so
combustible,
but
they
also
mat
down
those
tall
grasses
and
also
make
them
less
likely
to
spread
quite
as
quickly
and
so
in
rec.
We
are
recognizing
that
our
our
climate
is
shifting
that
the
hazards,
the
wildfire
hazard,
is
also
shifting,
and
so
we
need
to
accommodate
our
construction
practices
to
adjust
for
that.
So
that's
that's.
What's
going
on
with
the
ignition
resistant
requirements
for
for
these
homes,.
B
We
had
another
question
in
the
registration
about
realistic
costs
to
build
a
passive
house.
The
recording
is
not
yet
up,
but
last
week
the
colorado
green
building
guild
hosted
a
webinar
about
a
passive
home
that
was
built
in
louisville
recently,
for,
I
believe,
around
350
dollars
a
square
foot.
Don't
quote
me
on
that
either.
I
believe
it
was
in
that
range
that
recording
will
be
available.
B
D
Yes,
the
this
is
rick
hackett
staff.
The
medium
recording
will
be
posted
tomorrow,
wednesday,
on
the
marshall
fire
recovery
webpage.
There's
a
link
to
the
chat.
Sorry
I
linked
to
that
page
in
the
chat
that
you
can
look
at
there.
It'll
also
be
posted
on
our
youtube
channel
for
community
planning
and
permitting
the
video
itself,
and
I
can
put
a
direct
link
there
too,
and
that'll
be
up
tomorrow
tomorrow.
C
A
We
are
well
aware
that
many
people
are
still
very
much
in
the
the
early
stages
still
still
trying
to
to
get
their
bearings
to
work
through
their
insurance
companies
to
figure
out
where
things
stand,
we
do
recognize
that
there
will
be
ongoing
questions
and
we
really
do
encourage
people
to
to
reach
out.
Let
us
know,
what's
on
your
mind,
let
us
know
what
you
need
to
help
help
understanding
both
you
know
you
as
homeowners
or
any
design
professionals
that
you
work
with.
A
You
know
we
we
do
recognize
that
they're
likely
to
be
many
people
who
are
going
to
be
working
on
projects
that
haven't
been
working
in
boulder
county
or
maybe
a
little
less
familiar
with
some
of
the
some
of
the
code
requirements,
and
so
we
do
encourage
everyone
to
to.
Let
us
know,
what's
on
your
mind,
what
you
need
help
with
if
there
are
additional
workshops
that
we
need
to
put
together,
we're
happy
to
organize
some
additional
educational
and
outreach
opportunities.
I
know
the
cara
agree.
A
Building
guild
has
laid
out
a
pretty
comprehensive
sequence
of
presentations
on
many
of
these
topics,
but
we're
happy
to
to
engage
in
in
more
of
those
as
as,
as
might
be
helpful
to
our
community.
So
I
guess
with
that.
I'd
like
to
just
thank
everybody
for
your
time
and
to
thank
our
interpreters
for
helping
manage
that.
So
with
that,
and
thank
you
to
all
the
cpp
staff.
That's
that's
on
this
call
helping
to
put
this
together.
