Remodeling Building Systems: November 2008 Archives
Watch for more emphasis on energy efficiency, retrofits and weatherization under the Obama administration. Obama's weatherization plan is part of a comprehensive energy plan that will create green jobs and rebuild the US infrastructure of roads and bridges, schools, and housing for energy efficiency. Weatherization of schools, homes and offices will reduce oil usage for heating and cooling. Obama's emphasis on youth jobs and green jobs will contribute to economic recovery. The Obama weatherization plan will not only reduce energy use, but improve the health and productivity of children and workers who benefit from better indoor air quality, natural light and less toxic emissions from petrochemical energy sources.

How Healthy Are National Green Building Programs?, The National Center for Healthy Housing (NCHH) compared green building and indoor air quality guidelines.
The study recommends the following improvements be made to several programs to reduce contaminants:
Except for the NAHB (National Association of Home Builders) all programs require compliance with the ventilation standard ASHRAE 62.2. NCHH recommends NAHB add this requirement to their guidelines.
The study recommends the following improvements be made to several programs to reduce contaminants:
- Avoid the use of mold susceptible materials in areas likely to get wet (bathrooms). Use dense glass gypsum board instead of paper-backed gypsum board.
- Require sub-slab depressurization systems [radon mitigation system ] in new homes to help reduce soil odors.
- Set the hot water heater to 120 degrees F. This is primarily a safety issue although setting the temperature to 120-140°F vs. 160-180°F saves 10% energy as well.
