Energy Efficiency Truths When Designing Single-Ply Roofs
Learning Objectives:
- Design roof systems by choosing membranes based on color, and the role of membrane choice and insulation levels in building energy efficiency.
- Identify demand charges and the role they play in determining air conditioning versus heating costs.
- Describe roof installation methods and system designs and their impact on energy efficiency.
- Review trends in membrane types and understand how the market has changed, and go beyond today's code levels to become a more demanding or sustainability conscious building owner.
- Review commercial electric tariffs and their effect on HVAC operating costs.
Credits:
Roof design plays an important role in determining future operating energy costs for buildings. Membrane choice, insulation levels and attachment methods all play a role in building energy efficiency. This course examines membrane trends and the implications for the building designer in terms of energy efficiency. The effects of the type of membrane, along with methods of installation and previously published studies are reviewed. The importance of heating energy source, eg. gas versus electricity, will also be discussed. Using validated modeling tools, systems will be compared to show how energy efficiency can be improved. In addition, the impact of installation methods will be reviewed showing how roof assembly design can be improved in ways not yet considered in current building codes. Architects, designers and roof consultants will benefit from this course, as will building owners, facility managers and anyone in the roofing industry.
