The 2009 International Energy Conservation Code is designed to provide energy conservation provisions for both residential and commercial construction.
The code addresses building envelope requirements for thermal performance and air leakage, as well as the installation of energy efficient mechanical, lighting, and power systems. It provides regulations that will help result in the optimal utilization of fossil fuels and nondepletable resources. Please note that this code is no longer available in a loose leaf edition.
New to the 2009 International Energy Conservation Code:
- More stringency throughout the Energy Code
- Emphasis on energy savings requirements
- Higher R values in different regions
- More restrictive window and door U-Factor and SHGC values in warm climate zones
The 2009 International Energy Conservation Code will produce approximately 15% in energy efficiency gains compared to the 2006 Edition, according to Department of Energy. As a result, homes and commercial buildings, including schools and hospitals built in jurisdictions that adopt the 2009 International Energy Conservation Code, will consume less energy and help the environment by reducing emissions associated with building operation.
New energy efficient provisions in the 2009 International Energy Conservation Code include:
- Improved window and skylight efficiencies for homes constructed in "warm humid" and "hot humid" climates which lower energy costs during cooling periods
- An increase in insulation R-values for walls, floors and basements in cold climates to achieve greater heating and cooling savings
- High-efficiency light bulbs as a requirement in at least 50% of permanent lighting fixtures in new homes
- New separate requirements for high-rise condominiums and apartments regarding commercial insulation and window tables
- Radiant heating requirements for unenclosed public spaces
- Clear depiction of mechanical provisions regarding when and where a Demand Control Ventilation strategy is required.
Adopted for use in many communities, be sure to have this manual to stay code-compliant and pass inspection!
