A project of the National Institute of Building Sciences. The WBDG provides single-point uniform access and use of facility information in a knowledge-based management environment. It provides an overview of the various topics, concepts, and "best practices" associated with good 'whole building' design, and offers a ready means of accessing commercial and government guides, standards, and criteria needed to create such designs. The WBDG allows access to relevant information by direct links to other resources available on the Internet with the click of the mouse. This way, design objectives and performance requirements can be considered in concert with each other to achieve quality, high-performance building projects. At the heart of the WBDG are Resource Pages containing reductive summaries on particular topics written by industry experts. Click here for the Cool Metal Roofing Resource Page


The Cool Metal Roofing Coalition was founded in 2002 by five industry trade associations to help the public understand the business and environmental rationale for specifying cool metal roofing systems. The Coalition has the mission of educating architects, building owners, specifiers, codes & standards officials, and other stakeholders about the sustainable, energy-related benefits of metal roofing. The Sustaining Members of the Coaltion are shown below:

American Iron and Steel Institute (AISI)
For over a century, North American steel producers have left their day-to-day rivalries behind to work as partners and members of the American Iron and Steel Institute in furthering its mission to promote steel as the material of choice and to enhance the competitiveness of the North American steel industry and its member companies.

Metal Building Manufacturers Association (MBMA)
Organized in 1956, MBMA serves the metal building systems manufacturers, metal roofing systems manufacturers and associate member suppliers. Its membership represents more than $1.9 billion in annual steel shipments and accounts for approximately one-third of the total non-residential low-rise construction marketplace.

Metal Construction Association (MCA)
The Metal Construction Association was formed in 1983 with the purpose of promoting the wider use of metal in construction. Its website contains information on metal roofing manufacturers, their suppliers, and performance guidelines of metal roofing systems.

National Coil Coating Association (NCCA)
The National Coil Coating Association (NCCA) is an established trade organization dedicated to the growth of coil coated products. The NCCA consists of 160 member companies that are at the forefront of the industry. They provide the coil coating service and are leading manufactures and suppliers of metal, coatings, chemicals, and equipment.


The Metal Initiative (TMI)
The Metal Initiative is an industry-wide program designed to increase metal usage in the commercial construction market by educating building owners, architects, and general contractors about the many functional and environmental benefits of using metal.

Metal Roofing Alliance (MRA)
Visit the Metal Roofing Alliance website where you can view an assortment of residential metal roofing products, applications and case studies. Assistance is also available for locating metal roofing contractors.

Cool Roof Rating Council
The Cool Roof Rating Council (CRRC) is an independent and non-biased organization that has established a system for providing Building Code Bodies, Energy Service Providers, Architects & Specifiers, Property Owners and Community Planners with accurate radiative property data on roof surfaces that may improve the energy efficiency of buildings while positively impacting our environment.
