New super-efficient rooftop units that heat and cool commercial buildings offer significant energy and dollar savings, say scientists at the Department of Energy’s Pacific Northwest National Laboratory. They found that the devices reduce energy costs an average of about 41 percent compared to units in operation today.
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.
Heating, ventilation, and air-conditioning (HVAC) equipment, such as boilers, chillers, air handlers, furnaces, and heat pumps, make up some of the largest sources of energy consumption in most buildings. Not surprisingly, there is a big opportunity to optimize and reduce this consumption with better management and equipment improvements.
