Energy Efficiency


Central Oklahoma Habitat for Humanity has always built homes that were environmentally responsible and as energy efficient as possible.  Several special partners, though, have focused their giving to make Central Oklahoma Habitat the most energy efficient homebuilder in the state.  All of our new homes are being built to LEED (Leadership in Energy-efficiency and Environmental Design) Silver standards set out by the U. S. Green Building Council.  The result for Habitat homebuyers is an extremely affordable home that reduces utility costs by as much as half to a third of what they used to pay.  The sizeable reduction in energy bills combined with Habitat’s zero-interest mortgage maximizes affordability for our homebuyers, saving them thousands of hard-earned dollars each year back that can be reinvested instead into their families’ lives.  Now, that’s transformational! 

In addition to other design and site considerations, all Central OK Habitat homes are now being built to include:

Perimeter slab insulation;
Supersealed envelope and sealed attic;
Manual J-designed HVAC;
27-EER geothermal heating and cooling systems;
Icynene open-cell foam insulation in exterior walls and sprayed on underside of roofline;
Low-e argon-filled double-pane vinyl windows (U-value of <.35; SHGC

Paperless sheet rock in wet areas of baths;
Energy Star appliances;
Low-volume faucets and toilets;
CO detectors; and
Compact fluorescent lighting (CFLs).

The extreme efficiency of these homes is being made possible by very generous contributions from several energy-conscious partners.

Oklahoma City-based

ClimateMaster, manufacturer of extremely efficient geothermal heating and cooling systems, is donating a system to Central Oklahoma Habitat for each home being built.

Oklahoma Gas & Electric, through their Positive Energy program, is contributing to each home to help offset the additional cost of the other energy efficiency improvements.  They are also providing pro-bono home energy ratings and tax credit calculations that help us qualify for state energy-efficiency tax credits on each home.

Builders Insulation is working with insulation manufacturer Icynene to discount high performance open cell spray foam insulation for all of our houses.

Guaranteed Watt Saver Services, Inc. (GWSSI), the certifying entity, has contributed administration fees connected with LEED certification, as well as plan analyses and consultation fees.

We are extremely grateful to these very generous partners for helping make such a profound impact on families’ lives through utility savings.

Central Oklahoma HFH completed its first and only two solar homes at the beginning of 2008.  The solar improvements for those homes were underwritten by donations from ClimateMaster and OG&E.  No additional solar projects are planned at this time.
