Frequently Asked Questions

 

What is ENERGY STAR®?

The ENERGY STAR® Label is the national symbol for energy efficiency, developed by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). The ENERGY STAR label assists consumers with identifying major household appliances as well as many other consumer products that are more energy efficient than comparable products in the market place.

ENERGY STAR labeled products are the latest in innovative design and technology and they use less energy and save you money each and every month.

Does an ENERGY STAR® home cost more?

No! An ENERGY STAR labeled home actually costs less because you will spend less on your home’s utility bill each month. These energy savings can more than offset any increase in payments needed for the improved energy features, which can result in a positive monthly cash flow.

How much money can I save on utility bills if I buy an ENERGY STAR® home?

You can save 30 - 40% on your heating and cooling costs. The exact dollar amount will vary depending on your homes design, size and your personal comfort level. Savings across the U.S. averages between $200 and $400 per year.

Does an ENERGY STAR home help prevent moisture problems that can lead to mold issues?

  1. ENERGY STAR homes have properly sealed air ducts, which will help prevent the spread of mold spores from crawl space environments into the home.
  2. ENERGY STAR homes seal plumbing, electrical and other penetrations in floors and walls preventing spread of contaminants such as mold into the home.
  3. ENERGY STAR homes provide balanced airflows for the heating and cooling systems. This minimizes pressures in rooms that can push indoor moisture into walls and create potential mold problems.

Does making a home tighter lead to more issues with mold?

Not necessarily. Mold issues appear when a home has problems with moisture. These problems may be due to water from improper landscaping or plumbing leaks in the crawl space, improper flashings, lack of exterior rain planes behind siding and/or lack of proper ventilation.

Homes should have proper ventilation to help prevent issues with mold. The best building practice is to build a home tight and control the homes ventilation using mechanical ventilation such as kitchen, bathroom and whole house fans. All new homes are tight enough to need mechanical ventilation with make up air to control moisture.

How much ventilation is required in my home?

The ventilation system should consist of a kitchen fan, a bathroom fan and in some cases a whole house fan. The ventilation system should be sized to move about 1/3 of the house volume per hour. This translates into at least 10 cfm per bedroom plus 10 cfm for the rest of the home. For example, a 3 bedroom home would require a 40 cfm whole house fan plus a bathroom and kitchen fan.
