- Technology: A roof coating that absorbs less sunlight, and that makes roof colder than air even in high summer temperatures – discovered by researchers at theUniversity of Technology Sydney.
- Researchers claim that the new surface “stayed 11 degrees or more colder than an existing state-of-the-art white roof nearby because it absorbs only 3 per cent of incident sunlight while simultaneously strongly radiating heat at infrared wavelengths that are not absorbed by the atmosphere,”
- The advantages of a cool roof: improved energy efficiency, for more comfortable interiors.
- Potential overall advantage: “If enough roofs in a precinct are kept cool then the local climate can also be beneficially influenced.”
- Availability: Material used currently available commercially – may be suited to be used on basic roofing.
- Technology stakeholders:
- Regulatory Bodies/Government: Good to have a legislation that would push for the implementation of standardized special/white coat roofs on all new buildings. For existing structures, it would be good to have a regulation that would push existing buildings to comply with new requirements and make changes within a specified time frame.
- Architects and Construction Companies: would require these stakeholders to implement this special coated material on new projects/new constructions.
- Building Owners/Managers/Home Proprietors: would require these stakeholders to adopt special coated material on existing roofs.
- Implementation:
- Inform stakeholders of new technology (media outlets and direct mail) – showcasing overall benefit.
- Provide product availability information (shopping locations and cost info)
- Inform suppliers of upcoming demand (try to negotiate lower price)
- Commission lobbying people to push for legislation implementation
- Have regulatory legislation implemented
- Follow up with stakeholders to ensure implementation is being done successfully
