The SpecRight program has been developed by the National Roofing Contractors Association (NRCA) and is supported by GAF Materials Corporation, Johns Manville Corporation, Owens Corning Corporation, Sarnafil Inc., ERSystems Inc., Metal Construction Association, North East Roofing Contractors Association, Polyisocynurate Insulation Manufacturers Association and the Roof Consultants Institute.
Participation in the SpecRight program differentiates our company within the community by promoting a better understanding of the options for energy-efficient roof system design. We can beat the competition by illustrating how initial costs can be recouped through energy savings as well as improving our professional image by advocating energy conservation.
Customers will benefit by saving energy costs by lowering their energy consumption with the possibility of saving tax costs if they qualify for the tax incentives offered by some states and local municipalities. Our customers can beat the competition by increasing lease-out rates for lessors or increasing property value and they can act socially responsibly by conserving energy and other resources.
Breakdown of what the training session equips us for:
- Identifying variables that determine roof assemblies’ thermal performances.
- Implementing requirements from energy code standards, including ASHRAE 90.1-1999.
- The use of the NRCA’s EnergyWise Roof Calculator.
- Identifying ways roof systems can contribute to sustainable building design.
- Educating our customers about the benefits of energy-efficient roof system design.
- Earning a SpecRight Program training completion certificate allow us to advertise ourselves as being part of the SpecRight Program.
- Successful graduates of the training can use SpecRight-branded marketing materials.
Why would the SpecRight (energy related systems) program be of any use to contractors?
Natural gas production, according to the American Gas Association, has not kept pace with the rising demand; the market price of natural gas reflects the tight balance between natural gas supply and demand. Several factors are expected to continue to support high natural gas prices, including high world oil prices; continued strength in the economy; limited prospects for growth in domestic natural gas production; and the effects of recent hurricanes on production.
The average price for natural gas was approximately 35 percent more in 2005 than 2004. Current energy prices and long and short term outlooks are published by the
As world energy prices continue to rise, the electric industry will reflect this growing trend. The increase in 2005 of 5.2 percent is one of the highest recorded in the U.S., and there is little sign that future electricity price increases will abate. Because much of the electricity in the U.S. is generated using natural gas this commodity is so closely tied to world oil prices, electric rates are bound to continue to climb ever higher.
The reasons for the need to understand the importance of knowing about design and installation considerations.
There are several design issues to consider when improving the thermal efficiency of low-slope roof systems. In August 2005, President Bush signed comprehensive energy legislation to boost the economy and reduce the nation’s dependence on foreign energy resources.
The law introduced provides $14.5 billion in tax breaks. Recipients will include producers of oil, natural gas, coal and nuclear power, as well as smaller incentives for consumers who use cleaner-burning fuels produced in the U. S. For commercial buildings, building owners may qualify for the following tax breaks for improvements made in 2006 and 2007.
1.Up to $1.80 per square foot deduction for full envelope projects that exceed ASHRAE 90.1 by 50 percent (new construction). 2.Up to 60 cents per square foot deduction for partial envelope project that exceed ASHRAE 90.1 by 50 percent (reroofing projects).
Energy efficiency improvements made on residences in 2006 and 2007 may qualify for tax credit. The credit is 10 percent of the amount paid for qualified improvement. The maximum credit is $500.00.
What is ASHRAE 90.1-19999
ASHRAE 90.1-1999: Issued by the American Society of Heating, Refrigeration and Air Conditioning Engineers Inc.
It is a standard that sets minimum thermal insulation requirements and design parameters for use with reflective roofs, excludes single family houses, multifamily structures less than three stories above grade and buildings that do not use electricity or fossil fuel. In July 2002, the U.S. Department of Energy (DOE) mandated all states and municipalities must update their commercial building codes to meet or exceed ASHRAE 90.1-1999 standards. States must have done so, or requested an extension, by July 2004. Note: ASHRAE 90.1-1999 is incorporated into the International Energy Conservation Code (IECCO). In turn, IECC has been incorporated into the International Building Code (IBC), which has been adopted by a majority of states and localities. There are no roofing-related changes between ASHRAE 90.1-1999 and more recent versions.
Methods of roofing to help meet the standards
1.Double layer of insulation. Install the installation staggered. 2. Fasten-and-adhere, mechanically fasten the 1st layer of insulation and totally adhere the 2nd layer with either adhesives or mopping hot asphalt. 3. Roof reflectivity is using a light colored roof surface, which can be 70 degrees Fahrenheit cooler than a dark colored roof.
Cool roofs use roofing materials that have high solar reflectance and high thermal emittance. 1. How much of the sun’s heat is reflected away from the roof rather than absorbed (solar reflectance/reflectivity, or albedo). 2. How effectively the absorbed heat is released from the roof (thermal emittance/emissivity).
Cool Roof Benefits
Lower roof surface temperatures will reduce the total cooling load and peak electrical demand so net annual energy savings may be realized.
Improves the durability and the life of the roof.
Increases the efficiency of roof insulation.
Reduces air-conditioning loads, allowing a reduction in cooling equipment design load.
NRCA EnergyWise Roof Calculator can be used to offer an interactive, graphical method of constructing virtual roof assemblies to evaluate thermal efficiency and estimated annual energy costs. It also contains minimum thermal insulation requirements established by ASHRAE 90.1-1999.
California’s Title 24
Title 24 was originally passed in 1978. Its purpose is to reduce energy consumption in California, especially peak energy demand that can cause rolling blackouts. An October 2005 update regulated energy efficiency for roofs in California for the first time. The basic principle behind Title 24 is to establish and meet an energy budget for a building. The budget is based on the climate zone location of a building. California is divided into 16 climate zones.
Title 24 applies to all new construction, alterations and additions, including reroofing for nonresidential buildings with slopes of 1:12 or less that are mechanically air-conditioned or heated.
Information is knowledge and knowledge is power.
Marketing our company as knowledgeable about energy saving roof systems will result in more sales.
Eventually building regulations across the nation will be adhering to Title 24 and we have already been involved with this in the St. Louis area.
The Leadership in Energy and Environmental Design (LEED) is also making inroads into the St. Louis roofing market advocating the use of Green Roof Systems.
Use of Photovoltaic Roof Panels are now making inroads into roof design.
