New Buildings Institute (NBI) has developed what it calls the “first ever” set of plug load energy use metrics, which will allow easy insight into building energy use. A study of the NBI metrics to assess plug load energy use at PECI headquarters in the First and Main building in downtown Portland, Oregon revealed an 18 percent kWh reduction of PECI’s plug load.
40-year-old Philadelphia high-rise exemplifies new benchmark for energy efficiency in older buildings. The RENOVATE by Berkowitz™ (Renovate) window retrofit system has enabled 400 Market Street, a 12-story building in Philadelphia, to reduce its annual heating and cooling energy consumption by more than 25 percent and significantly improve indoor comfort according to results from a year-long study funded by the U.S Department of Energy.
Featuring Individual Control of Multiple Room Units And Standard-equipped with High Value-added FunctionsTokyo, Nov 25, 2013 – (JCN Newswire) – On November 25 Mitsubishi Heavy Industries, Ltd. (MHI) will commence domestic marketing of a newly developed series of packaged air-conditioners, the “HYPER VSX Series,” equipped with the dual capability to control multiple room units simultaneously or individually.
A unique software application created by the Energy Department’s National Renewable Energy Laboratory (NREL) could improve the efficiency of commercial buildings by allowing occupants to interact with buildings more directly.
The sequence of operation is one of the most important design aspects of any HVAC system. Without a proper sequence, the system is left to operate wildly—or not at all. When approached methodically, the process can be broken into smaller segments. We’ll look at the steps required to create a successful sequence of operation using a single-zone variable air volume (VAV) air handling unit serving a convention space. These same steps can be applied to any piece of equipment.
Many would say building automation technology has paved the way for numerous changes in the way structures are monitored and maintained during their lifecycles. Among those changes is the way a building’s energy use is tracked, and subsequently adjusted to make it more green and cost-efficient. As time goes on, such practices may become more common.
With modern glazing systems and sophisticated designs that minimize glare issues, daylighting for industrial buildings is making a strong comeback.
Desk-based technologies and other electronics that plug into office building receptacles draw a considerable amount of power, some of it 24/7. In fact, “plug loads” account for roughly 25% of total electricity consumed within office buildings. GSA currently owns and leases more than 370 million square feet of building space in some 9,600 buildings nationwide. The size of this real estate portfolio alone suggests the possibility of enormous energy savings, if plug loads can be reduced.
