Green Testing: Southwest Inspection and Testing has added a new division to its laboratory. A GREEN TESTING Division. In Accordance with Title 24, Southwest Inspection and Testing will incorporate HERS Testing and Solar Reflectance Testing (ASTM E1918) to its index.

Solar Reflectance Testing: This test method covers the measurement of the solar reflectance of various horizontal and low-sloped surfaces and materials in the field, using a pyranometer. This test measures Albedo, which is the ratio of outbound or reflected solar radiation to inbound radiation. This test aims to improve environmental and economic performance of buildings and sites.
"A study on the influence of pavement albedo on air temperature in Los Angeles predicted that increasing the albedo of 490 sq miles of pavement by 0.25 would save cooling energy of $15,000,000.00 per year and reduce smog-related medical and lost-work expenses by $76,000,000.00 per year. Concrete surfaces often have higher albedo than surfaces constructed of other materials, and can be made even higher by judicious selection of constituent materials. Reducing the urban heat island effect through cool surfaces is being promoted by organizations such as the U.S. EPA, Energy Star, LEED, and energy codes." ~

HERS Testing: The California Energy Commission is required by Public Resources Code Section 25942 to establish regulations for a Home Energy Rating System (HERS) Program to certify home energy rating services in California. The goal of the program is provide reliable information to differentiate the energy Efficiency levels among California homes and to guide investment in cost-effective home energy efficiency measures.
The California HERS Program includes field verification and diagnostic testing available through Commission-certified providers and their raters when duct efficiency, thermostatic expansion valves (TXVs), refrigerant charge and airflow measurement, and building envelope sealing measures are used for complying with the new 2001 building efficiency standards (effective June 1, 2001).
