Roof Hugger, Dawn Solar enter partnership

Energy efficient and sustainable roof systems’ are very much the topic of the day in the construction industry. In response, Roof Hugger, Inc. the metal construction industry’s leader in metal-over-metal retrofit systems is incorporating existing and proven energy saving technologies offered by Dawn Solar Systems.

This strategic alliance provides Roof Hugger and Dawn Solar customers with the expertise and integrated products for developing renewable energy solutions that reduce dependency on fossil fuels and other direct energy sources. The technology’s unique means of harnessing solar energy, coupled with the ability to integrate systems into building architecture without compromising design aesthetics, is making these products a desirable choice for today and the future.

The systems include solar heat recovery and solar thermal heat collection for water, process and space heating in retrofit and new construction applications. In retrofit, the fundamental principle for these systems is utilizing the air-space cavity that is created by installing Roof Huggers between the old and new roofs.

For new construction, the air-space is created by first installing a metal sub-deck over the purlins with a Roof Hugger and then insulating for maximum thermal resistance. The application provides a very clean underside roof assembly, which enhances lighting and interior aesthetics. The air-space in both applications present several options to the contractor and building owner.

For code compliance, high density board insulation is installed across the sub-deck ribs parallel with the Roof Huggers. Atop the insulation is the Dawn Solar reflective radiant insulating barrier having an R-Value of 10. With a minimum overall thermal resistance of R-26 being required by the Model Energy Code/ASHRAE 90.1 for new metal building construction, the insulation board can easily be selected from any number of manufacturers with products having a minimal R-Value of 16.

For retrofit, the insulation type can be fiberglass or board insulation and as far as R-Value, it is up to the building owner and/or design professional.  The more the better for energy conservation is the “rule of thumb."

Simply stated, these systems can be used to improve the building inhabitant’s comfort and environment as well as provide significant energy benefits through alternative energy resources. Approved by the Solar Rating and Certification Corporation, the systems qualify for extensive Federal tax credits available for commercial buildings. When used in a retrofit reroofing application, the credits are even greater. Under the conditions of the Economic Stabilization Act of 2008 and the more recent American Recovery and Reinvestment Act of 2009 (a.k.a. Stimulus Bill), commercial building owners that improve their energy efficiency using solar systems may be eligible for tax credits as allowed by Section 179 of the U.S. Tax Code. These credits have been extended for projects completed prior to January 1, 2017. The tax credit amount is a dollar-for-dollar credit that equates to 30 percent of the total in-place cost of the system (roof panels, sub-purlins and solar equipment including labor).

In addition, the installation is eligible for IRS Bonus Depreciation, which allows 50 percent the first year and the balance over the following five years. Depending where your project is located, a multitude of State and Local loan guarantees/funding, grants, renewable energy bonds and tax programs are available. For agricultural projects, even more benefits may be available including Federal grants up to 25 percent of the overall cost of the system.
