DoD Is Retrofitting 577,500 Buildings with High-tech Roof Systems

The nation’s largest energy user, the Department of Defense (DoD), is learning how to transform some of its 577,500 buildings and structures into state-of-art energy-saving powerhouses, by retrofitting old buildings with new high-tech roofing systems. In partnership with the Metal Construction Association (MCA) and the Department of Energy’s Oak Ridge National Laboratory, the DoD is host to a demonstration project for reducing a building’s carbon footprint and lowering demand for energy and water. The demonstration project was part of the DoD’s Strategic Environmental Research and Development Program (ESTCP) at Goodfellow Air Force Base (GAFB) in San Angelo, Texas. The model will be replicated at potentially thousands of DoD buildings throughout the country.

“We are thrilled to see this technology come together. Both the MCA and DoD see a great benefit to the broader U.S. economy when new and retrofit buildings throughout the country adopt this high performance roofing design, and work toward net-zero energy buildings,” says Scott Kriner, Technical Director, Metal Construction Association.

The dynamic roofing system was installed at the Security Forces Building at GAFB and performs many functions, using a combination of technologies that heat and cool air and water, produce electricity, and collect rainwater. The metal roof retrofit system can be installed over an existing roof, saving installation costs and keeping old roofing material out of landfills. What makes this roofing system unique is that it brings together multiple functions in one holistically designed, integrated building envelope system that can be used on flat or sloped roof designs.

The technology used is a hybrid of metal roofing, insulation, hydronic solar thermal systems, engineered air pathways, and photovoltaic (PV) cells, all designed to work symbiotically. This high performance system includes a retrofitted metal roof installed over the existing roof, which creates a cavity between the existing and new roofs. Within that cavity insulation, solar thermal heating systems and cooling of air and water for the building can be installed. More specifically, the technologies incorporated into the metal roof system are:

    1) Cool metal roofing: high solar reflectance coatings on metal save up to 25% in summer cooling energy costs and helps mitigate the heat island effect in urban areas.

    2) Solar thermal water heating: sun is used to preheat water for use inside the building, reducing the use of fossil fuels or electricity for hot water heaters. The heated water can also be used for space heating using a heat exchanger.

    3) Rainwater harvesting: this subsystem harvests, manages and reuses rainwater for non-potable applications such as watering landscaping or flushing toilets.

    4) Solar electric (PV) panels: thin film solar panels laminated on the roof provide energy for the building and even allow electricity to be sold to the grid.

With the roofing system installation at GAFB, the Department of Defense and the Metal Construction Association are demonstrating how integrating energy efficiency and solar technologies with a retrofit metal roofing system can reduce energy and water consumption, mitigate the building’s environmental impact, and lower construction and operating costs.

New Report Forecasts Global BIPV Markets

BIPV Markets Analysis and Forecasts 2014-2021 research report addresses BIPV glass, roofing and siding and assesses the prospects for the competing underlying technologies including thin-film, OPV, DSC and c-Si. It includes forecasts broken out by product, application, technology and region expressed in MW and units.

This latest report “BIPV Markets Analysis and Forecasts 2014-2021” updates quantitative and qualitative assessments and outlooks for the global building integrated photovoltaic market. The publisher of this research has been covering the BIPV market since 2007. This 2014 version of the BIPV market report examines the latest important technological and market developments as well as the various region specific factors shaping the market. While the last few years have been far from robust for the solar market there are reasons for companies and investors to view BIPV with some optimism.

The report addresses BIPV glass, roofing and siding and assesses the prospects for the competing underlying technologies including thin-film, OPV, DSC and c-Si. The research includes forecasts broken out by product, application, technology and region expressed in MW and units. The report also provides commentaries of the various leading key suppliers and industry influencers.

BIPV Glass Markets: 2014 & Beyond industry research report includes a detailed eight-year market forecast with breakouts by type of building and PV technology and in both volume and value terms. This report also discusses how BIPV glass can better be sold to architects, who are sometimes skeptical of the BIPV glass concept, but remain the key decision makers on the demand side. In part this is about improved marketing. But as we discuss in this report, it is also a matter of playing up the aesthetic advantage of solar glass (for example with tinted and colored products) and by incorporating additional smart features such as hybrid light/photovoltaic capability.

CIGS Photovoltaics Markets: 2014 and Beyond industry research report analyzes the opportunities that are emerging for CIGS in the very new phase of the solar industry. The report takes a detailed look into the technical evolution of CIGs fabrication and encapsulation and show how this will impact CIGS market expansion and cost reduction. Much of the report is devoted to the opportunities for CIGS in building-integrated PV (BIPV market) and how CIGS flexible modules and price parity with silicon solar panels could considerably improve the revenues generated by CIGS technology in the near future.
