- At this moment, money may be trickling out of your pocket via energy gained or lost through the windows of your home or office space. Here are tips to help.
- According to energy analysts, most homes spend about a quarter of their energy on heating water.
- The key is to understand how to ventilate intelligently to improve health, save on energy, reduce repair bills, and health care costs.
- Consumer-facing web site will serve as a resource and forum for people wanting to make their homes more comfortable and energy efficient.
- How residential building envelopes can act as particle filters.
- Fully a quarter of the electricity used in the average German household now goes for information, communication, and entertainment electronics.

- One of the easiest and most cost-effective ways to reduce energy use at home is to ensure that your home is properly insulated.
- According to DOE’s Building America program data, typical, residential ductwork efficiency is about 67%. That means that if you install a 90% efficient furnace, your system efficiency would be just over 60%. Another way to look at this is that ducts lose 25–40% of the energy that moves through them. Just from a practical standpoint it makes sense to improve the delivery system. Shorter, straighter, better engineered and installed ductwork will improve delivery efficiency.
