Most Earth-Friendly Home Ever Built?
Jan. 20, 2015 - The group Habitat for Humanity is building six homes in Washington, D.C., that are not only affordable but also energy efficient. Known as passive houses, these homes meet rigorous standards through low-energy construction practices and energy-efficient appliances. Whereas the average household in the area spends up to $1,500 annually on energy, passive-house owners can expect to reduce those costs by up to 90 percent.

VOLUNTEER COORDINATOR SOT:
Good morning, Everybody. We’re
very lucky today. Today is a good day
because we have two homeowners that are doing the sweat equity program. You’ll be working with them. They’re great. So, this is a nice day.
DAN HINES, CONSTRUCTION SUPERINTENDENT, HABITAT FOR HUMANITY
OF WASHINGTON, D.C.:
Everybody has heard for Energy Star and LEED. Passive is kind of that to the
Nth-power. It’s very energy efficient,
as tight as you can be and really focuses on how do we best use the energy that
goes into a house.
To start off, they are super-insulated. They’re built airtight. So they accurate design where windows are
placed, what kind of glazing is put on them, everything like that to try to
smartly use they energy that just inherently comes into a house from sunlight.
You have to use Passive House certified windows in order to
be certified. And the cost of those
windows is much higher but it is because they’re much better. All these windows have insulated frames. These are usually at least three panes. So it does cost more in upfront cost for us
to build a Passive House but we way that against the fact that it is going to
cost a lot less for our homeowners to live in their house throughout the course
of year, meaning their energy costs are going to be very low and manageable and
should be standard, meaning they’re the same from month to month.
SUSAN SLATER, , PRESIDENT AND CEO, HABITAT FOR HUMANITY OF
WASHINGTON, D.C.:
We do know that an average house in this area spends at
least 1,200 to 1,500 dollars a year on energy costs. And we expect that to be reduced by about
90%.
On a cost benefit, it’s a hands down win-win for
everyone. It’s definitely great for the
homeowner. It ensures that they have
enough cash to pay their mortgage and they have much more financial
flexibility.
YENESALEM SATA, Passive House Recipient:
Today I’m coming here today to participate with Habitat and
volunteers. I came from Ethiopia. I have been in America almost about six
years. I’m living now in an
apartment. It’s almost two bedrooms
which is not comfortable for my kids as well as for myself.
All my family is very interested in the plant when they see
it is an environmental place and how the house is constructed. I prefer this construction for my long life.
DAN HINES, CONSTRUCTION SUPERINTENDENT, HABITAT FOR HUMANITY
OF WASHINGTON, D.C.:
It’s really important to use that our homeowners be able to
afford the house that they’re moving into.
IF we can spend a little more money building it and getting it to this
really great energy standard, then our homeowners over the next thirty, forty
years get to be able to know exactly how much they are going to spend and spend
a lot lesson on living in their house.
