Recovering from Heat Recovery Woes

The International Energy Conservation Code (IECC) has a number of requirements involving energy recovery on ventilation systems. Requirements vary based on climate zone, building type and size, equipment capacity, and equipment operating hours. As a result, many new construction projects must now incorporate energy recovery considerations into their design. An energy recovery unit (ERU) equipped with […]

When the Rubber Meets the Road

  As the Passive House standard continues to make waves across New York City and the U.S., an entirely new design process has evolved to respond to the challenges of higher insulation levels, balanced mechanical ventilation, and perhaps the most difficult hurdle – an air tightness level that most would think is impossible. For the […]

Transformers: Problems in Disguise

Sometimes a significant source of energy inefficiency in a building can be hiding in a place difficult to detect. In some buildings, a single transformer can have a substantial impact on electrical consumption. Some Background Transformers are responsible for stepping the incoming voltage to a building up or down depending on the design, intended use, […]

Designing Solar for High Density Areas

Hear the term “solar energy” and you’re likely to think of vast fields of glistening panels and hillsides transformed into disco balls. Hear the term “solar energy” and you might picture suburban McMansions with roofs that reflect the sky. Hear the term “solar energy” and you envision… skyscrapers? Affordable housing units? Clusters of panels lurking […]
