New Home Energy Audit Standard Published
The Building Performance Institute Inc. has published the BPI-1100-T-2012 Home Energy Auditing Standard. The document is designed to provide the home performance industry with a resource to enable home energy audits to be conducted in alignment with current industry practices.
The new standard provides the protocols to conduct a building-science-based evaluation of existing detached single-family dwellings and townhouses that meet specific criteria detailed in the scope of the standard, BPI officials state. The evaluation addresses energy usage, elements of building durability, and occupant health and safety; provides a comprehensive scope of work to improve the home; and includes a cost-benefit analysis. By applying the standard to their projects, home performance professionals are able to ensure that energy audits are conducted as thoroughly as possible, it is noted.
Related to windows and doors, the document notes that an "energy audit shall include an evaluation of the performance of the building enclosure and include recommendations for upgrades." Specifically, inspectors are to "evaluate window performance and fit by testing operation." Additionally, auditors are to provide an estimation of U-factors and solar heat gain coefficientsof windows, doors and skylights, as well as "evaluation of the feasibility and energy savings for window treatments, interior and exterior" and "evaluation of window improvements in thermal resistance and/or exterior shading devices."
BPI is proceeding to have BPI-1100-T-2012 published by the American National Standards Institute as an American National Standard, and will open a public comment period for this ANSI process in the near future, the organization notes. Developed by a working group comprised of subject matter experts representing the home performance industry and a variety of interest categories and geographical locations, the standard has already undergone multiple rounds of public review.
The organization has also released its new Standard for Residential Building Quality Assurance Related to Post-Installation Field Inspections (BPI-6300-S-201x) for public comment. Also known as the QA Field Inspection Standard, the standard includes protocols for third-party inspectors to confirm that home performance upgrade measures have been installed in accordance with the workscope and applicable standards.
A special web forum has been set up for those interested in viewing the inspection standard and submitting comments.
