Building Dynamics - The Roof

The Roof functions as one of the most important features in a building

Basic Function - Provide WeatherproofingNew Impact - Energy Conservation

Improve Air QualityManage Storm Water

The Energy Star® Roofing Program

An EPA and DOE Program to promote the use of highly reflective

roofing products to lower energy consumption and improve the

environment.

Energy Star Roofing Program

Why is this important?

•Energy Conservation•Environmental Benefits

•Reduce the effects of Urban Heat Islands

•Reduce Smog Development

Reflective Roofs

Energy Star Roofing ProductsBENEFITS

Reduce energy consumptionReduce cooling costs Reduce heat island effectReduce smog developmentExtend real time roof life

Urban Heat Island EffectAreas that are warmer than the surrounding

country-side. The temperature rise is caused by a combination of development and the abundance of heat absorbing dark surfaces on paving and roofs.

Roofs made of non-reflective products cause the temperature of the air passing over them to rise, resulting in an increase in the overall temperature of

the area.

Why is a Heat Island a Problem?

Hotter temperatures reduce comfort & increase incidences of heatstress

More energy, money & pollution expended to run air conditioning systems

Higher energy demand leads to power reliability problems, brownouts & blackouts

Air quality worsens since smog forms more readily in hotter airMore smog leads to more respiratory distress

Reflective Roofing Impact

Benefits of Reflective Roofing•Highly reflective white roofs help

reduce energy costs in every climate.•Reduce Urban Heat Island•Reduce Overall energy

consumption•Increase air quality/Smog reduction•Longer life of the roofing products

•Longer lifecycle for mechanical units

Green Roofs

What is a Green Roof?

A Green Roof is an area of planting on a waterproof substrate at any level that is separated from

natural ground by a man made structure.
