In the August 2008 issue, Journal of Light Construction published an article titled: Making the best of rising energy costs, by Paul Eldrenkamp. In his article, Paul talkes about different building standards, one of which is Passive House. Paul also addresses one of my biggest issues with “green” building — the leck of emphasis on energy! I could not agree more that we can do so much better in terms of performance of buildings.
While Energy Star and LEED offer a potential 25% reduction in energy consumption over code-construction, Passive House uses energy modeling and field-testing to deliver up to 90% reduced energy consumption for space conditioning, and a 75% reduction in overall source-energy consumption. All of this at a very small increase in day-one construction cost, which are easily offset in a very short amount of time, while creating real value, increased sale or resale prices, and up to 25% quicker sales.
Passive House retrofits offer the potential of reducing energy consumption for space-conditioning by up to 80%. This is still much more than a LEED conversion would yield. Nevertheless, LEED can be a great partner, as many of its requirements compliment Passive House standard quite well.
So, enjoy Paul’s article and consider energy when looking at your next project, no matter what the type or budget may be. Improvements can be made at any step along the way. And the benefit is always yours.
