Energy Use Intensity (EUI) is an indicator for how energy efficient a building’s design and operations are. EUI is not the same thing as energy use, but understanding the types of energy can help us to better understand the EUI metric.

BERDO 2.0: Boston’s Drive Toward Decarbonization
BERDO is a city ordinance in Boston. BERDO’s goal is to improve the performance of large existing buildings.

BERDO 2.0 came along in 2021 and builds on the first ordinance to not only require annual reporting, but also mandate performance requirements to drive decarbonization.

But tall buildings come with additional challenges and risks that owners and property managers have to consider. As we build up, it becomes increasingly important that we protect what’s below – from low-rise buildings to everyday pedestrians.
That’s why Boston passed the Boston Facade Ordinance 9-9.12 in 1995, which requires the exterior walls of buildings meeting certain criteria to undergo periodic inspections.

Thermal Bridging, Derating, and the new 10th Edition MA Stretch Energy Code
Have you ever come across the term “thermal bridging“? You may start hearing about it more now that the Massachusetts stretch energy code requires more analysis related to thermal bridging.
In short: thermal bridges are thermally-conductive points, lines, or areas in the building envelope which allow heat to pass through more easily.
