SSS SSS STRATEGIES FOR REDUCING ENERGY DEMAND IN OPERATIONS AND MAINTENANCE: ¢ USE FREE ENERGY. Use the facility’s orientation and appropriate shades, windows, and vents to take advantage of natural ventilation, solar energy, and daylight.
- MONITOR CONSUMPTION. Use energy monitoring and feedback systems to encourage occupants to reduce energy demand. SSS DEMAND RESPONSE Demand response (DR) strategies encourage electricity customers to reduce their usage during peak demand times, helping utilities optimize their supply-side energy generation and delivery systems. One strategy is tiered demand electricity pricing. Another is incentive programs that reward commercial consumers who agree to change their usage patterns when the utility company sends an alert (to the building’s operator or the building automation system) announcing a DR event (also known asa curtailment event). DR programs set a maximum number of events that can be announced and specify the time frames in which they may occur. By reducing overall demand for electricity, DR helps utilities avoid building additional power generation facilities, transmission lines, and distribution stations, thereby avoiding some of the environmental effects of energy infrastructure and consumption. DR also helps balance the contribution of renewable energy sources. For example, on calm days or at night, when renewable sources such as wind and solar are less available, grid operators must either find additional generation sources or persuade energy users to lower demand. DR achieves the latter, balancing systemwide usage and reducing the need for nonrenewable backup generation. REDUCE DEMAND BY REDUCING BUILDING SIZE Zz = Energy demand typically increases in direct relation to building size: the more square feet in a building, a the more energy it consumes. Although there are exceptions, the relationship between square footage and & consumption is very strong. 4 i | The LEED for Homes rating system includes a point adjustment to compensate for the effect of square a footage on resource consumption. This prerequisite is for projects using the Energy and Atmosphere 3 prescriptive path. w i uh LEED for Homes is currently the only LEED rating system with this type of adjustment. 6 oO WwW a fe} oO a w Ww =| 66
