A Need to Increase Energy Efficiency

Share this on:

Residential energy use accounts for 20% of greenhouse gas emissions in the United States. The American Institute of Architects, the U.S. Green Building Council and others are promoting an energy-efficiency strategy called the 2030 Challenge. It aims for “residential and commercial buildings built today to use half the amount of fossil fuel of average existing buildings, plus a gradual increase in energy performance so that new buildings are carbon neutral by 2030.”

Energy consumption (through occupant behavior) needs to be reduced and energy efficiency needs to be increased, in the existing 124 million housing units in the U.S.. A good time to do upgrades, like increase exterior insulation, is when one is already doing renovations such as replacing siding. As far as renewable energy sources go, like photovoltaics, ideally they should only be installed if the building envelope has been tightened through air sealing techniques.

There are many things that can be done to combat global climate change and where we live and work are good places to start.
