Facility directors looking for ways to improve building performance, reduce energy consumption, and shrink their structure’s environmental footprint would do well to focus first on their lighting, cooling, space heating, and ventilation systems.
Green projects are constantly underway throughout the nation and HVAC contractors have embarked upon a number of environmentally conscious efforts, showcasing innovative displays of green awareness that improve energy efficiency and are cost-effective.
The pressure independent valves can provide real savings in systems that have the low delta T syndrome, which seems to affect a lot of campus style centralized chilled water/hot water systems. The low delta T situation is mostly encountered during part load conditions and is manifested in excessive pumping.
Heating, ventilation, and air conditioning (HVAC) in commercial buildings accounts for approximately 40 percent of total building energy consumption, but advances in HVAC technology can provide for much more efficient and less energy intensive operation.
New York City will formally unveil a plan tomorrow that will involve investing $1 billion into making public buildings more energy efficient over the next ten years. The changes will involve swapping out old lights for LEDs, replacing aged air conditioners and other changes
Advanced thermostats communicate to the Internet, enabling visibility and control of HVAC systems via the web. Communication capabilities create opportunities for energy and demand savings through smarter controls and enhanced HVAC performance management by maintenance staff. Additionally, the advanced thermostats can integrate with and control other energy consuming systems, such as lighting.
