Last year, we wrote about New York State’s plans for replacing the 2,000 megawatts of electricity provided by Indian Point. As of March 2018, Indian Point is still slated to close in April of 2021. The New York State Independent System Operator (NYISO) will reassess the plant’s retirement plan later this year and will continue […]
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 […]
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, […]
Variable refrigerant flow (VRF), also known as variable refrigerant volume, was a concept developed by Daikin Industries in the 1980s. The technology is based on transferring heat through refrigerant lines from an outdoor compressor to multiple indoor fan coil units. VRF systems vary the amount of refrigerant delivered to each indoor unit based on demand, […]
