When retrofitting buildings for efficiency, replacing windows can be a great place to start. Windows can comprise up to 25 percent of a property’s exterior wall area and can account for up to 50 percent of a property’s heating and cooling demand (1). However, replacing otherwise functioning windows only for the sake of increased efficiency is generally not cost effective. Windows tend to be expensive, and the cost savings due to increased efficiency will usually not recoup your initial investment in a satisfactory time period. Continue reading ENERGY STAR® Windows
While California’s 2017 drought may be receding into memory, property owners should still prioritize water cost control in multifamily buildings. In addition to the cost of water, the energy used to heat water makes up, on average, 15 percent of a property’s utility bills. In addition, during hot summer months, water use due to landscaping, pools, and spas increase, and so do water and sewer costs. Reducing water use presents an opportunity for multifamily properties to conserve water and reduce spending on both water and energy.
The following are three ways in which your property can take control of water costs.
Home energy management systems (HEMS) allow for monitoring, measuring, and controlling multiple end uses including appliances, HVAC, hot water equipment, and plug loads throughout the home. Note, HEMS can refer to a standalone technology, such as a singular smart thermostat, or a suite of interconnected components. A HEMS provides homeowners a high degree of control over energy use in the home, and allow homebuilders to market units as energy efficient and green.
What is the Building Envelope, and Why is it is so Important to Energy Efficiency?
Simply stated, the building envelope is the physical barrier between the conditioned environment (heated or cooled) and the unconditioned environment. The envelope typically consists of walls and insulation, doors, windows, and roofs. These components work together to keep conditioned spaces comfortable for residents by minimizing the amount of heat transfer between the interior and exterior. Continue reading Building Envelope
How to save energy and money while reducing water use
California’s growing population, coupled with last year’s recent, historic drought, makes water conservation a priority for the state. With future water costs in flux and the threat of drought always a factor, it makes sense for properties to get ahead of the curve and reduce water use. Luckily, there are many devices available to reduce property-wide water use.
