ENERGY WISE GUY
FEBRUARY 2012
Over the next few months I will address twelve issues that should be taken into consideration when building your new home. The more information you have on green building methods and products, the better armed you will be when it comes time to take on your project. This information is being provided by GreenBuilder Magazine.
(This article is a continuation from the January Energy Wise Guy Column)
Air Control – Protecting indoor air quality isn't as simple as choosing low VOC paints, although that is one important step. You will also want to:
- Evaluate Flooring – Many carpets and synthetic underlayments produce toxic fumes. Select brands specifically aimed at reducing offgassing, and install with low VOC adhesives.
- Control Ins and Outs – Most modern homes are built (and remodeled) to be very tight. Mechanical ventilation may be needed to control the flow of fresh air into the home and the movement of toxins and moisture out.
- Bust the Dust – The smallest, most dangerous pollutants are not removed by most stand alone vacuum cleaners. Units with HEPA filters or whole house vacuums are the best way to get particulates out of the living areas.
Windows – Choosing the right product is just one part of the sustainability story. It is critical that you also consider the other variables.
- Orientation – Which compass direction will the window face? Is it maximizing the potential for natural daylighting and solar gain (in northern climates)? Is it shades by roof overhangs in hot southern regions?
- Installation Details – Improper flashing and/or a shoddy caulking job can easily neutralize a window's energy savings.
- Long Term Maintenance – Low maintenance does not mean “no maintenance.” Follow the manufacturer's recommendations for keeping your windows in good working condition.
Heating Systems - Any type of heating system can perform better, if you know which features matter the most.
- Slow Comfort – Water based heating systems tend to retain and release heat more slowly than forced air furnaces. An efficient boiler with in-floor tubing or radiators offers an efficient comfortable form of heating.
- Duct Diligence – To improve the performance of the existing forced air furnace, seal and insulate the ducts, then clean or replace the filters every three months.
- Upgrade and Save – Modern, high efficiency equipment tends to burn far less fuel and produce less air pollution than older models, no matter what the fuel type.
