Bill on Energy Efficiency Could Impact Commercial Glass Usage
The United States House of Representatives passed House Bill (HB)
3221, Renewable Energy and Energy Conservation Tax Act of 2007 on
August 4. Some of the bill's proposals aimed at modernizing the
country's energy infrastructure could eventually have an impact
on the use of glass in commercial buildings.
According to information from the American Architectural Manufacturers
Association (AAMA), the bill would require:
- A 30-percent reduction in energy use from the 2006 International
Energy Conservation Code (IECC) for residential buildings and
from the 2004 American Society of Heating, Refrigerating and Air-Conditioning
Engineers (ASHRAE) standard 90.1 for commercial buildings by 2010;
- A 50-percent reduction of the same by 2020; and
- That 100-percent of all commercial building be zero-net energy
Part 4, section 9044 establishes the zero-energy commercial buildings
initiative. The goal of the initiatives is to "periodically
study and refine a national goal to reduce commercial building energy
use and achieve zero-net-energy commercial buildings."
Part 4 also establishes that a high-performance green building
is a building that "improves indoor environmental quality,
including reducing indoor pollution, improving thermal comfort,
and improving lighting and acoustic environments that affect occupant
health and productivity
Among several high-performance green building practices, the bill
recommends further research into the relationships between health
and occupant productivity and natural daylighting, among other things.
The bill also lists incentives to improve commercial building energy
efficiency. Among the incentives suggested are trade-in programs
for the early retirement of low-efficiency commercial building system
components, including windows.
