Through the use of the DoD Environmental Security Technologies Certification Program (ESTCP) the military is providing grants to industry in order to demonstrate novel technologies, products and systems aimed at meeting their energy and water conservation
One such ESTCP grant was awarded in 2010 to a team of metal construction industry leading companies and the Metal Construction Association. The grant of approximately $1 million is being used to demonstrate a retrofit metal roof system with integrated
renewable energy technologies that showcases a holistic assembly of six different roofing system components.
The project targeted retrofitting a metal roof on a 10,000 sq ft Security Forces building on the Goodfellow Air Force Base in Texas. Installation of the retrofit project along with a data acquisition system from DOE’s Oak Ridge National Laboratory
was completed in June 2012. The ESTCP grant was awarded because It is so unique, in that, it is the only retrofit metal roofing system integrating other energy saving technologies to form a building envelope.
Prior to the installation of the retrofit system, DOE’s Oak Ridge National Laboratory installed a data acquisition system to monitor various temperatures and heat information on the building. In addition to measuring energy data, the building’s
utility billing information was collected. When the baseline of energy usage was established, installation of the retrofit metal roof system began in April 2012.
The integrated technologies were installed in the following manner:
- Structural purlins were installed over the existing metal roof.
- Additional insulation was placed over the existing roof to meet the current code requirements, using rigid board insulation.
- A waterproof roof underlayment was then applied over the insulation.
- A radiant barrier was installed over the underlayment.
- An integrated solar thermal system using a closed loop tubing array with water/glycol mix heat exchange medium was installed over the radiant barrier to optimize the heat transfer.
- The thermal purlin used to position the solar thermal system tubing is configured to allow for above sheathing ventilation (convective cooling) to take place from the eave to the ridge.
- 24 gauge prepainted polyvinylidene fluoride cool coated standing seam metal roof panels were laminated with a solar PV system and then installed directly over the solar thermal system.
The holistic use of these integrated components into one retrofit system is designed to maximize electricity generation and to minimize the cooling load of the building. In addition, the solar thermal technology that is integrated into the retrofit cavity
will optimize the energy generated for domestic hot water and for space heating.

Take Paramount Metal Systems' New AIA CES Course Here
Integrated Metal Roof Retrofit with Multiple Energy Saving Technologies, sponsored by Paramount Metal Systems, examines key drivers behind the design and development of an innovative new metal roof retrofit system, engineered to both conserve and generate unprecedented levels of energy. Features and benefits of the new retrofit system are explored through an extensive case study of the system's first real-world application - the Security Forces building at Goodfellow Air Force Base in San Angelo, Texas. The course also provides a complete step-by-step installation of the new metal retrofit roof system through the use of a full scale mock up, in narrated HD video.
