A steam heating system combines a steam boiler with a distribution system consisting or pipes, valves, and radiators. Steam heating requires more maintenance than hydronic or warm air because of the make-up water flowing into the boiler. Often the boiler water needs water treatment to keep it clean enough to make good steam.
Saving energy in multifamily buildings is similar to saving energy in homes. The choices become different for multifamily housing as the building increases in size. The fact that one building is home to many people also becomes a factor in selecting energy conservation measures. For example, insulating walls is more difficult in multifamily buildings because you need access to every[…]Read more
Many recent advertisements tout specific electric space heaters as being superior to others. This article explains the operation of the two general types of electric space heaters and discusses advantages and disadvantages of different designs. Electric resistance space heaters are a good energy efficiency strategy if they allow homeowners to heat their homes to a[…]Read more
Human nature makes us adopt new and exciting ideas. The recent interest in all things green is an example. Energy conservation is the best way to make your home more environmentally responsible, or green, but how do you find a contracting company that is as green as its advertising represents? The term Home Performance describes[…]Read more
Air leakage causes curiously high heating and cooling costs in buildings that are supposed to be energy-efficient. This shouldn’t be a mystery. You can’t achieve airtightness without trying. Airtightness has never been a goal of the building construction industry, and that isn’t changing. Most buildings, both homes and larger buildings, don’t really have an air[…]Read more
The Homeowners Handbook to Energy Efficiency John Krigger is a passionate and respected authority on energy-efficient construction. He is the author of several publications on the topic. He recently spent three years in Europe studying super-efficient construction and is working with homeowners across North America to establish sure-fire ways of implementing this zero-energy construction approach.
