ETFE: The New Fabric Roof May 15, 2009 Introduction Ethylene Tetra Fluoro Ethylene – not the sexiest of names; however, ETFE foil is fast becoming one of the most exciting materials in today’s design industry and has set the construction world alight with the potential it offers. Originally invented by DuPont as an insulation material for the aeronautics industry, ETFE was not initially […] Read More
Benefits of Cool Roofs on Commercial Buildings May 15, 2009 INTRODUCTION Cool roofing is “hot.” It is a frequent topic in trade magazines and at roofing symposia. Sales of various cool roofing products outpace the overall market year after year. Manufacturers expend significant development resources working on the radiative properties of their materials, looking to improve their market positioning and share. With all the talk […] Read More
Rooftop Equipment Supports May 15, 2009 Rooftops have commonly been used as a haven for the installation of various pieces of equipment with the mentality, “We have nowhere else to put them,” or “Let’s just put it up on the roof,” with very little thought or concern with the overall possible impact they could have on the service life or performance […] Read More

How Does a Thin-Film PV System Affect Cooling Loads on a Building? May 15, 2009 ABSTRACT Using calculated cooling loads and calculated energy generated by a photovoltaic (PV) system, it was determined that the additional cooling load caused by a thinfilm PV surface requires no more than 2.5% of the electricity generated by the PV system itself. The added cooling load is due to the lower solar reflectance (SR) of […] Read More

Considerations For Copper Roof Design May 15, 2009 Copper is the oldest metal known to man.1 Few consumers understand the chemistry and physics of copper cladding, but they do seem eager to express opinions regarding how it looks. Copper has low “columnar rigidity.” There is nothing particularly wrong with this property, but cautions must be observed to avoid unappealing aesthetics and substandard performance. […] Read More
