Montgomery County, MD, Has a BEPS. What Do You Need to Do Now?

Montgomery County, MD, passed Bill 16-21, which creates a Building Energy Performance Standard (BEPS) for buildings within the county. The law also expands benchmarking requirements within the county, requiring private and Montgomery County-owned buildings over 25,000 square feet to benchmark energy use no later than June 1, 2024, in advance of demonstrating energy performance in the future.

Montgomery County BEPS: What We Know

Montgomery County’s BEPS phases in across different groups of buildings between 2024 and 2027. Each group will have 10 years to meet the BEPS for their particular building type.

Most importantly, each building will need to demonstrate that it meets the BEPS. All but the highest-performing buildings over 25,000 square feet may need to take some action. (more…)

The Numbers Are In! NYC Passive House Performance Data

In a collaborative effort that merged financing and energy use analysis, the New York City Passive House industry finally has performance data. Working together with Bright Power, The Community Preservation Corporation, and NYC Department of Housing Preservation & Development, this analysis is the first of its kind.

Why does this matter?

Energy Use Intensity (EUI) measures energy consumption on a per square foot basis to compare buildings and allows interested parties to gauge one building’s usage to another (or to a group of buildings with a similar use type). The study team compared the actual EUI of six completed Passive House-certified and Passive House-like buildings against recently completed multifamily code-built buildings. Information was gleaned from the EnergyScoreCards database and the Passive House (PH) target. The weather normalized data indicates the Passive House and Passive House-like buildings are performing much better than the comparable code-built group, but are not quite as efficient as the Passive House threshold. Industry leaders have recognized this performance gap – between predictive assumptions that rely on standardized patterns of use and the real-life habits of actual people living in the building. This gap has been a hot topic  at the past several New York Passive House conferences. The results from the current analysis provide a starting point now, so the industry can focus on strategies to continue to reduce EUIs.
