3. Why?
We have the ability and knowledge
to build homes that produce as
much energy as they consume,
while at the same time maintaining
a long-term perspective on
protecting our planet’s resources.
The question is no longer
how we do it, but why not?
8. These homes weren’t all bad
They were
usually built in
town, close to
amenities and
the workplace.
Many were built
to use passive
cooling methods
rather than air
conditioning.
9. What about their cars?
Cool car! How
would this stack
up in terms of
performance
against today’s
cars?
15. So how are we doing?
How much more efficient do
these advancements in
technology (insulation, double-
pane windows made in a high-
tech factory, high-efficiency
HVAC, and others) make our
homes?

20. A Scary Statistic
In 2010, per capita
consumption of
energy averaged
48 percent above
the 1949 level.

24. Your Grandchildren’s Home
Continuing our mental experiment: we
saw our grandparents house, we
explored today’s houses, so what will
the houses of our grandchildres look
like?
Where are we in the evolution of
home design?
27. How do you envision the home of the future?
How about: A high performance building
enclosure designed to passively ensnare
and amass infrared energy coupled with
an active grid-tied array of ultra thin
layers of phosphorus-doped and boron-
doped silicon producing a steady flow of
electrons?
Probably not...
We don’t think that way, we think about
how things will make our lives easier and
more fun...
28. A great home design doesn’t have to be overly
complex - it’s more about working right. And
ultimately, it’s about more than us, it’s about being
stewards of our planet.
30. Two Questions
1) How do we build the home of
tomorrow, today?
2) How do we make that home something
that everyone desires? WHY will they
want it?
The how is fairly easy, that’s what this
presentation is about. The why is the
real challenge! Each and every one of us
need to lead by example, and create
homes that benefit our lives as well as
benefit the environment.

Net-zero homes are not just
about adding a hundred solar
panels to every house, but
about reducing the
consumption of the home to
where it can be easily balanced
by a renewable energy source.

Zero Energy Take Home: Total Cost of Ownership
-Does a ZEH cost more? Yes, upfront. No in the long run.
-In some ways, it’s like taking all the money you would have
spent over the next 20 years on electricity and investing it in
your house now. When you do that, you can offset that
electricity from ever being used at today’s energy prices,
and that’s a powerful thought.

39. More than likely, you did not have your last car hand built, piece by
piece, outside in the rain. No, you bought a car that was built with
careful attention to detail, exacting tolerances and excellent quality
control, all thanks to advances in the car manufacturing process.
Now, think of how most homes are built.
40. Now think of how most homes are built. The differences are
quite poignant. Many homes spend a significant amount of time
exposed to the elements. Site built homes are typically limited in
the tolerances they can achieve, and hence these homes have a
high degree of variability.
