- Energy Star appliances and products - the Energy Star program is a partnership betweeen the EPA and DOE to help "save money and protect the environment through energy efficient porducts and practices." Energy Star provides ratings on over 50 categories of products (including windows and appliances) and now includes ratings for both homes and commercial buildings.
- High-efficiency windows - windows are an important part of the energy picture in our heating-dominated climate that will, along with other considerations such as siting and shading windows appropriately and then selecting glazing that maximizes solar gain and minimizes heat loss, will decrease energy consumption and save money.
- High-efficiency heating and cooling equipment - heating and cooling buildings (both homes and commercial) accounts for up to half of the energy costs. Selecting and sizing heating and cooling equipment for optimum efficiency in the context of the whole building design is part of the IGD process.
- High-efficiency lighting - integrating daylighting and high-efficiency lighting systems can decrease energy use and improve comfort and productivity.
- Motion sensors/automatic dimmer controls - as part of an integrated automatic lighting control system these components reduce energy use and operating costs by automatically adjusting lights based on usage and available natural light.
- Ground source heating and cooling - by combining underground loops and heat pumps this system uses the relatively constant temperature of the earth to provide both heating and cooling. Typical annual energy savings are in the 30-60% range.
- Heat recovery ventilation systems - these systems are designed to optimize the recovery of heat from air that is being exhausted from a building and transfer it to incoming cold air that is required for proper ventilation. Most effective in areas like ours with very cold winters.
- Daylighting - designing windows and reflective surfaces so that daylight provides as much good quality illumination as possible. Reduced use of electric lights and solar heat gain contribute to lower costs. In our heating dominated climate careful attention to glazing materials and orientation delivers the best results.
