“…For the student apartments, 37% source energy savings were projected throughout the B10 Benchmark in hot-dry climates (Dakin et al 2012). These measures, and specifically the package of measures, have the potential to lead to market-ready solutions that cost-effectively provide comfort in multifamily buildings with efficient, safe, and durable operation.…”

“…A 2012 ARBI study (Dakin et al 2012) documented the West Village design processes surrounding the development of the package of energy-efficiency measures. The 2012 report presents the 2009 evaluation of heating, ventilating, and air-conditioning and water-heating options completed in conjunction with the West Village Community Partnership, LLC (the West Village project developers).…”

The work presented in this report does not represent performance of any product relative to regulated minimum efficiency requirements. The laboratory and/or field sites used for this work are not certified rating test facilities. The conditions and methods under which products were characterized for this work differ from standard rating conditions, as described. Because the methods and conditions differ, the reported results are not comparable to rated product performance and should only be used to estimate performance under the measured conditions. v Contents List of Figures .

“…Over the 25-year PV lifespan, the electric DHW heater would accrue $13,600 more RECs than the heat pump. A back of the envelope calculation estimates that the additional cost of PV panels and an electric heater is about 3 $6375 more than the purchase of a heat pump, whose price was adapted from DEG [38]. Ironically, assuming an electric heating system costs $6375 more upfront but saves $13,600 in credits over its lifetime, the electric system would save a net $7225 compared to an energy efficient heat pump, in the case of one Ramble Apartment building.…”

Appliance time-of-use in a net-zero energy apartment was shifted to offpeak hours. Net-metered residents were not charged for consuming more than they produced. Residents accrued twice as many credits by shifting heavy-duty appliances.For some rate structures it is only beneficial to schedule between May and October. Electrically heated homes accrued more credits than those using a heat pump.g r a p h i c a l a b s t r a c t a r t i c l e i n f o b s t r a c tThis paper investigates the financial incentives of load shifting under a time-of-use rate and Net Energy Metering pertaining to the solar net-zero energy apartment community, West Village in Davis, California. By ''smart-scheduling'' the electricity and domestic hot water demand of the dishwasher, clothes washer, dryer, sinks and showers solely to off-peak periods, the peak demand is reduced by 18%, the part-peak demand by 32% and the off-peak demand increased by 12%. With this shifted schedule customers accrue twice as many credits as they would receive under a non-shifted schedule with the same time-of-use rate, totaling to $2975 of ''free'' electricity per year for one 12 unit building. But, under current rates smart-scheduling is found to be worthwhile only during the months from May through October, when 96% of the credits are accumulated. If the rate schedule is altered to include peak-periods during the winter months, the credit savings will double again in value. These comparisons are prepared using two photovoltaic simulation programs (PolySun by Vela Solaris and System Advisory Model by the National Renewable Energy Laboratory) and for apartments using an electric heater and a heat pump for domestic hot water. By quantifying these savings, PV generating customers are informed that a time-of-use rate can benefit them significantly, especially if the surplus generation is maximized and sold to the grid during peak day time hours. With this information, housing developers can create effective incentives for residents, and utility companies, policy makers and designers of smart-scheduling household appliances can encourage a more reliable, clean and economical national grid.
