Aug 23rd 2010 Going Green!
We’ve gone paperless; we’ve gone plastic-less…now there’s a new phase to the ‘green’ era. A Deep Energy Retrofit: a way to make your home more comfortable and eco-friendly.
A Deep Energy Retrofit (DER) is essentially refitting your existing structure by super-insulating and making extensive improvements to enhance energy performance, usually with reductions in energy of 50-90%.
Before you start, it is important to know how your existing home is using and consuming energy. To achieve this, you can study utility bills from the past year. You can also perform infrared imaging, blower-door testing, or duct-blaster testing for more specific results. There is also an energy feedback device available to measure how much electricity your home is using. Testing should also include the exterior parts of the home (building envelope), such as the exterior walls, insulation, roof and ceiling, and air sealing. In order to know which areas to concentrate on, these tests are vital to the retrofit process.
This type of green remodeling takes a great deal of planning for such a comprehensive and invasive project. Space heating and cooling, hot water, lighting, appliances and electric loads are the systems that are considered as part of the retrofit. More specifically, insulation/super-insulation, air sealing, moisture management, replacing roof/windows/doors, properly vented combustion appliances, alternative a/c, more efficient plumbing and insulation of hot water pipes, high-efficiency water heaters, increased natural day lighting, provisions for an easy way to turn off equipment to eliminate phantom electrical loads, and possible installation of alternative energy sources are what will be closely looked at for renovations. In addition, because moisture is such an important issue that must be managed, other possible improvements may include perimeter drains in the basement, exhaust fans in the kitchen and bathrooms, solar energy installations on the roof, and solar hot water collectors.
A deep energy retrofit will improve the indoor air quality of your home, which will ultimately improve your health and comfort. It will also make your home more durable and safe, as well as, reduce greenhouse gas emissions, save on energy costs, and increase long term affordability.
There is one other benefit that you might be able to take advantage of, if you’re thinking of “going green”. It is the Deep Energy Retrofit program from National Grid. If you’re interested, see our blog “National Grid’s Deep Energy Retrofit Program” for general information.
