Learn - Why you may be looking at your number one energy drain - your windows!
Higher performance windows may contribute from 15 to above 20% improvement over an ASHRAE 90.1 baseline building. Our Energy 10 simulations indicate that for Zone 3A if you go from a required minimum of U 0.57 for a typical commercial office building to a U value of 0.12 there will be a 24% improvement.
The first rule of renewable energy use is to reduce your energy requirements. Solar PV panels may be a cool visual statement but in some cases it's like watering your yard with bottled water.
Gilkey Architectural Windows and Glass Facades has just published a Primer with the assistance of Green Cincinnati Education advocacy on using glazing to assist in achieving LEED Certification Credits. From basic Prerequisites and Energy Modeling Simulations in EA Credit 1, you'll learn how the right glazing selection can impact your design and contribute to Material Resources and Indoor Air Quality with recycled and regional content along with all the operable styles available.
Since regional content calculation are by weight and glass is usually about 80% of the weight of a window or curtain wall, fenestrations may contribute almost 10% of the LEED material value of a project.
