BPI Releases New Standard For Multifamily Energy Performance

The Building Performance Institute, Inc (BRI) released BPI-1105-S-201x: Standard Practice for Multifamily Energy Auditing to help identify weaknesses in energy efficiency. The audit defines the minimum criteria for conducting a building-science-based evaluation of existing multifamily buildings. This provides specific technical procedures to conduct a multifamily building energy audit.

Created by BPI's Multifamily Standards Technical Committee (MSTC), this new standard reflects the best practices and advances in technology, according Andrew Brooks, chair of the group who developed the tool. The group is comprised of experts with different specialities located is various locations.

"The new Multifamily Energy Auditing Standard builds upon the strong foundation of the Multifamily Building Analyst Standard, but is far more expansive in scope and aims to address building types and systems that are found in every region of the country," stated Brooks.

The energy audit includes:
  • on-site evaluation of the residential units
  • common area public spaces 
  • all central building systems affecting energy use in residential space, 
  • will address energy usage and limited aspects of building durability
  • used as a tool to evaluate occupant health and safety. 

A comprehensive report with prioritized recommendations on how to improve the building. It will also include a cost-benefit analysis of all proposed measures.

This standard is currently undergoing American National Standards Institute (ANSI) review, which includes a 45-day public comment period as defined under BPI's standards development process. Comments are being solicited from stakeholders and the general public. 

The standard is currently under review and and for more information and to comment, please visit Standards Under Review and Formal Public Comment Process

GreenEdu offers a Home Energy Auditing course. Students learn about home energy auditing techniques and how to apply the skills in a real-world scenario. Against a backdrop of degree day theory, concepts behind calculating by measure, saving paybacks, building science, infiltration theory, and approved retrofits, class participants will learn home energy auditing techniques and apply them in a field exercise. Techniques include blower door guided air leakage tests, heat systems testing and analysis, material estimation, measuring and working with a field data collection form.
