The science of resource and energy efficient buildings and building process is well developed, though not routinely practiced in the design, construction or maintenance of today’s homes! “Green” is on an upward trend as more people learn the wisdom of building or remodeling using resource and energy efficient design and construction.
We are committed to raising the awareness of the benefits of going green and making it easier to do so. And we are committed to supporting homebuilders, homeowners and homebuyers by applying the principles and methods of green building and performance testing standards.
A less well understood impact of air leakage is the devestating impacts it can have with in wall assemblies. Insulation R-value is drastically reduced with air flowing through it, making it little more than an air filter. Air flowing though walls will cause moist warm air to condense when it reaches the cold exterior, causing mold, mildew and often rot !!!
EVERGREEN Energy Tips:
Building Envelope Science
> In Michigan, 60 % of the homes energy use is from heating. Heating losses occur through air leakage (convective energy flow) and insufficient or ineffective insulation (conductive energy flow)
> The most cost-effective energy improvement for most homes is locating and sealing the numerous areas of air leakage into the building
> Sealing air leaks to tighten the buiding shell has benefits beyond the obvious, such as the reduction of uncomfortable drafts and saving on utiltiy bills. It also makes your existing insulation do the job it is supposed to do.
> Insulation is tested in the lab to be R-13 or R-19 and so on with no air flowing through it. Fiberglass with air flowing through it is also called "filterglass" because of the dark streaks of dust collected from the air.
> Sealing air leaks creates the air barrier that most insulation needs in order for it to perform as intended,
