In buildings, energy efficiency means using less energy for heating, cooling, and lighting.

An important concept for energy efficiency in buildings is the building envelope, which is everything that separates the interior of the building from the outdoor environment: the doors, windows, walls, foundation, roof, and insulation. All the components of the building envelope need to work together to keep a building warm in the winter and cool in the summer.

Here are some web resources to help our members increase their energy efficiency:

• Is my home energy efficient? (i.e. how to perform an energy audit)
• Are my appliances energy efficient?
• How can I reduce my energy usage?
• How do I read the EnergyGuide label?
• How do I get the most out of my heating and cooling systems?
• How do I weatherize my home or busines?
