Specifying Building Insulation for Sustainable Design Energy Savings & Acoustic

Forty years ago, a green building was understood to refer to its paint color and energy efficiency meant turning down the thermostat . In that era, building insulation was a generic concept without a lot of differentiation beyond products for high temperature appli cations like steam piping wrapping compared to products for general building applications in wall and roof cavities. But we all know times have changed. Today, building owners, energy codes, green rating systems, and our own definition of good design no w require n ew and renovated buildings to perform at high levels of reduced energy usage, positive indoor air quality, and respons ible materialc hoices. Accordingly, the building insulation industry has responded with many new or improved products that have va riously met these 21st century performance criteria including products that are now being manufactured from recycled materials su ch as newspaper and cotton denim. Architects who understand the principles of effective insulation and who can evaluate the proper ties between different insulation products will then design buildings that perform better, last longer, and truly deserve the tit le of a green or sustaina ble building.
- Differentiate between traditional and emerging insulation materials, trends, and uses.
- Examine and recognizethe different ways that insulation addresses energy losses in a building envelope.
- Compare and contrast the acousticproperties of insulation against its energy saving properties.
- Analyze and assess multiple other qualities of insulation that can contribute to green and sustainable building design.
