WEBINAR – Evolution of Solar Thermal Requirements in US Building Codes

This webinar was originally presented in January, 2019, and provides an overview of the codes that impact the solar heating and cooling industry across the U.S. It identifies the relevant model codes and where they are adopted. It also notes states where local and amended codes are being used, creating localized requirements. The webinar describes ways key solar industry standards like SRCC Standard 100, 300 and 400 are referenced in the codes. It also shows how many other non-solar standards like NSF 61, NSF 372, UL 1703 and ASCE 7 can apply to solar heating and cooling systems. It ends by showing how certifications and listings are used to show compliance with code requirements.


Federal Investment Tax Credit for Solar Thermal Products

The federal Investment Tax Credit (ITC) provides for tax credits for various renewable and energy efficient products in residential applications in some cases. Solar Water Heating equipment is addressed by this credit, which requires the product to be "certified for performance by the nonprofit Solar Rating and Certification Corporation or a comparable entity endorsed by the government of the state in which the property is installed." ( 2016 IRS Instructions for Form 5695, Cat. No. 66412G ). For more information consult the IRS Instructions for Form 5695, IRS Instructions for Form 3468 and a qualified tax professional. Additional resources are provided below.


Database of State Incentives for Renewables & Efficiency (DSIRE)

DSIRE is the a comprehensive online source of information on incentives and policies that support renewable energy and energy efficiency in the United States. Established in 1995, DSIRE is operated by the N.C. Clean Energy Technology Center at N.C. State University and is funded by the U.S. Department of Energy. DSIRE contains information on many regulations and incentive programs for solar heating and cooling technologies, most of which reference SRCC OG-100 and/or OG-300 certification. The easy-to-use website allows users to seek out programs applicable to their U.S. state and technology and application of interest. Click here to learn more about DSIRE.


Natural Resources Canada (NRCan) Energy Simulation Tools

Natural Resources Canada has developed and maintains energy simulation tools for low-rise residential buildings. The software was designed to support the EnerGuide Rating System, ENERGY STAR® for New Homes and R-2000 energy efficiency programs. NRCan also supported the addition of Canadian One-Day Ratings to most ICC-SRCC OG-300 system certifications. This value, which is based on the conditions established in the CAN/CSA F379 Series-09 (R2013) - Packaged solar domestic hot water systems standard.
