Why Multifamily Properties Should Consider Heat Pumps
When it comes to heating and cooling homes in PG&E service territory—which mostly features a mild, Mediterranean-type climate—heat pumps are a great alternative to air conditioners (AC) and furnaces. Heat pumps provide exceptional efficiency, can enhance safety, and improve indoor air quality. Continue reading Why Multifamily Properties Should Consider Heat Pumps
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
