Project Description:
Proposes to research the feasibility of new IR reflective coatings that can be applied to residential concrete or clay tile roofs to achieve a minimum 40% solar reflectance.
Proposed Outcomes:
§ Five experimental IR reflective coatings of different primary colors
§ Building energy simulation models for collecting temperature data and computing the reduction in cooling power demand and cooling energy usage by applying the IR coatings.
§ Feasibility analysis based on performance of prototype coatings.
Anticipated Benefits:
§
This technology has the potential to reduce the cooling
load in residential homes with cement or clay tile roofs. Potential to reduce roof deck temperature
10-20%.
§ Coatings could be used on existing homes as a retrofit product, which increases the potential impact to the CA electric market.
