So why do we care? Why is it important to have codes? Because you save money for one thing
you reduce energy consumption, it improves the environment.
The savings are significant if you can keep money in your local community
the multiplier effect of that is quite significant.
It's a very important thing to do. To try to drive jobs
out of energy efficiency and if you reduce CO2 emissions and improve
the
atmosphere, well that's great.
I mean the concept whether you believe
CO2 issues or not
the issue is
at the end of the day we make the world a better place so why the dickens wouldn't
we try to do it?
I mean that's it at its base level.
So we look at this we see,
energy codes and standards, the history
we have the
model energy codes for residential that
turned into
the IECC, International Energy Conservation Code,
90.1
got codified in 1989.
We've got the commercial, the federal standards here that are
leveraging these
and saying thou shalt build to these levels.
So this is
in a sense that history and now we see on the stair step, you'll see this again
later in the other
presentations, but what this says is
the takes 1970 energy... I'm sorry...'75 energy use index
as equal to 100.
And what we see is with each
change and, at that time called the
model energy code, we see the improvements. 10 percent, 2 2 2,
1 1 1, for many years,
and then all the sudden whoa! some big steps
big important improvements
starting at around 2006
of ultimately 30 percent
because we're starting to see...
remember I said ASHRAE, AIA and others.
Smart folks who were saying "darn it.
We need to get serious about this business for a bunch or reasons."
"About efficiency in buildings."
"We need to push the envelope." Well, gosh I'll tell you could fall asleep at the
wheel and still probably end up in your driveway up here.
You could be designing...you know I mean?... You could be designing to code,
right? And, "oh gosh a new code's out. Okay now"
"I've got maybe a"
"lighting power density that's a little tougher well I'll just put in a lower wattage bulb."
"That's easy ho ho ho."
"I can do that."
But guess what?
You get to steps that are 15 percent,
that's a different religion let me tell you.
All of a sudden
you've got to do something that's quite serious. You've got to change the way
that you design buildings if your
an engineering firm.
And if if you hung your hat on
building the cheapest possible buildings
and designing the same system you've designed for the past 10 years
and just building to meet code,
then guess what,
you're gonna have an all-hands-on-deck meeting when that 15 percent hits
the
fan, right?
Because that's going to have a serious impact on your business.
So why build to the lowest common denominator?
Maybe you'll end up like General Motors.
You build the least efficient, you gotta get bailed out. Well were never big enough to be
bailed out so,
who knows.
But that's what happened with
residential, now commercial. We're seeing bigger steps at different times but
again ultimately
driving down, we see
standard 90.1 and the IECC both
moving towards that
ultimate goal of netzero energy it's like perfect golf
it's like juggling with six, you know, bowling balls.
"This is impossible! How are we going to do this?! Oh my gosh!"
But that's where we're driving.
The IECC and the 90.1.
Now how you use them. The IECC applies to residential.
Now both apply too small
commercial
and large commercial
but honestly what you might often find is that the IECC might be used a
bit more often on the small commercial but
when it's larger, you're often going to use the 90.1. Part of the
reason is the energy model.
At least that's my opinion.
The energy model that allows you to deal with more complicated systems and
controls of
day lighting strategies, of
demand control ventilation, underfloor air distribution systems that are
a little more challenging to
try to understand how you can hit a performance-based
target.
The energy model if you start it early enough it's based upon your design
you can leverage and you can learn from it you can improve it
to the point where
all of a sudden you can simulate
various elements of
the glazing, the tinting, the solar heat gain coefficients, whether you put cool
roof on,
the insulation values in the walls.
You develop this wisdom
and you take this tool and ultimately you bounce the design off the
walls. And you determine: what gives me the best life-cycle cost impact?
Should i consider a four pipe system for this?
What about
an air-side economizer. What would be the brightest thing for me to
do in this building from an energy efficiency standpoint? The energy model
is amazing.
It can allow you to do these things. And the 90.1 standard
has an element in the back chapter,
energy cost budgeting approach, that allows you, it lays out the
procedure for doing this.
So you see that the 90.1 and the IECC have stair stepped together at
alternate times
as the each come out with
new versions, they
become more stringent
as it goes forward.
It's the basis for the IECC 2009.
ASHRAE Standard 90.1.
Purpose to provide minimum requirements for the energy-efficient design of
buildings,
except low-rise residential buildings,
that's the 90.2.
Why is it important?
That is the 2007 version, It replaces 2004.
The basis for many voluntary rating systems
and also incentive systems
so you'll find that APS Solutions for Business
and SRP Business Solutions,
and the LEED program,
they all tie their horses to
different versions
of this program.
Of the 90.1.
It's the refernce standard for
2009.
And where can you get it? Well,
that's where you can get it. It's going to be in your notes
but either through the website or you can make a phone call.
Other standards the 189 we spoke about the 90.2 for
residential low-rise buildings
and the 100-
2006R, that's the
existing building standard that will come out soon, I hope so.
ICC.
Created by ICC.
I'm sorry, the International Green Construction Code created by ICC,
ASTM, USGBC, AIA,
and IESNA.
Did I miss anybody?
I don't think...ASHRAE.
Model code approach.
So it allows you to,
as a community, as a jurisdiction,
to select this particular code,
to become your basis for green building and not just energy efficiency
and it can be an overlay or it can be adopted in whole or in part.
So it gives that opportunity
and again 3 communities in the state. Most states don't have any communities
that have
adopted this code.
But it's Kayenta township, Scottsdale and City of Phoenix.
Why? Why should we do this Mark?
Why do we have to do this Mr. Wilhelm? Well, you don't have to.
But you can choose too and I highly recommend you choose to.
So we look at it,
tax incentives, rebates, utility incentives
the low-interest financing we spoke about, all of these incentives
that you can deliver to the owner
or if you are the owner that you can harvest yourself.
And if you are
in private business,
if you are one who is knowledgeable about these things and bring them to an
owner you might develop a strong relationship and ongoing business.
