Last year, Jim Urbanski, Energy Manager at Wicomico County Public Schools in Maryland, spent 20 hours each week scheduling heating and air conditioning for after-school events. This year he spends just 20 minutes to schedule two weeks of events. That is a 99% reduction in labor hours, and he isn’t done yet.
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.
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.
Zondits reached out to Greensleeves and asked their President and CEO to speak about geothermal systems in general and more specifically about using Greensleeves’ patent-pending software.
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.
