The Use of ccSPF in High-Performance Wall Assemblies May 15, 2011 INTRODUCTION How a wall is constructed can greatly diminish or enhance a building’s ability to be labeled “high performance.” This article will highlight the use of closed-cell spray polyurethane foam (ccSPF) utilizing HFC 245fa blowing agent packages in commercial wall assemblies, taking into consideration how the use of ccSPF accomplishes key high-performance building goals. High-Performance […] Read More
Field Investigation Of Aggregate Blow-off Of Spray Polyurethane Foam Roofs May 15, 2011 ABSTRACT The 2006 International Building Code disallows the use of loose-laid aggregate on roofs in hurricane-prone regions for fear of damage caused by blow-off. This restriction has had a significant impact on the roofing industry, as loose-laid aggregate has historically been used as an economical material to increase ultraviolet, fire, hail, and traffic resistance to […] Read More
Photovoltaics in Roofing May 15, 2011 As a result of the desire to achieve energy self-sufficiency with “clean energy,” solar energy production has increased an average of more than 20% each year since 2002, making it the world’s fastest-growing energy technology. Government subsidies and the possibility of selling excess production back to the power grid have led to building owners to […] Read More
An Introduction To Photovoltaic Systems May 15, 2011 Solar photovoltaic (PV) systems are widely known for their ability to generate electric power for homes and commercial buildings through the absorption of energy from the sun’s rays. In the movement toward increased sustainability, cleaner energy, and lower utility bills, they are becoming a more common sight, especially in regions of the country where sunlight […] Read More
Cool Roofs and Photovoltaics Work Together to Enhance Generation Performance May 15, 2011 It seems like a natural marriage of sustainable technologies: solar panels and cool roofs. Why not combine the energy-saving logic behind cool roofs with the energy-producing value of a rooftop solar system? One company reports that the output of its solar power system, when combined with a cool roof, increases 20% due to the improved […] Read More
The Certified Solar Roofing Professional (CSRP) Credential: Realizing The Promise Of Roof-Mounted Photovoltaics May 15, 2011 There is little question that roofmounted photovoltaics (PV) have ushered in a new era in the roofing industry, and with this change comes a promise of new careers; business opportunities for contractors, consultants, and manufacturers; and opportunities for energy cost savings to building owners. Realizing these promises for all stakeholders demands new levels of knowledge […] Read More
Bio-Based Roof Coatings May 15, 2011 Worldwide, most people are looking for greener, bio-based, natural, or sustainable chemistries to replace petrochemicalbased products. Natural (something that is not produced or changed artificially) is not the same as bio-based. Consider, for example, that crude oil comes from a natural source. The United States Environmental Protection Agency (EPA) states: Green chemistry, also known as […] Read More
