Heat Pump Water Heater Model Validation Study
A substantial fraction of the electricity consumed in the residential sector is used to heat water. Indeed, it is the second-largest single end use of electricity next to space heating. Due to the sheer size of the load there is substantial opportunity for energy use reductions. Recognizing the importance, heat pump water heaters (HPWHs) have…

Agricultural Irrigation Initiative: Using Soil Electrical Conductivity Mapping for Precision Irrigation in the Columbia Basin
Variable Rate Irrigation (VRI) and Variable Speed Irrigation (VSI) applications require accurate maps of soil water-holding capacity as inputs to the applied water prescription generation process. Thus, determining accurate soil variability information and conducting soil mapping are necessary steps toward successful implementation of precision irrigation.2 These accuracy requirements are typically not satisfied by freely-available soil…

Agricultural Irrigation Initiative: Precision Water Application Test
As water becomes increasingly scarce, agricultural management of this precious resource becomes ever more critical. Maximizing performance of agricultural land and minimizing the use of water and other resources, such as energy, requires optimal use of new irrigation technologies such as Variable Rate Irrigation (VRI).

Agricultural Irrigation Initiative: Pivot Evaluation Best Practices
Growers using center pivot irrigation delivery systems generally schedule irrigation based on the driest ten percent of a field. While this approach meets crop water requirements for most areas, it can overwater others. The challenge of uniformly meeting crop water requirements is compounded when the amount of water applied by the center pivot’s sprinklers varies…

Agricultural Irrigation Initiative: Grower Experience
Market adoption of precision irrigation practices and technologies requires acceptance and use by growers within the contexts of their farm operations and agronomic practices. While these technologies offer the promise of improved yield and corresponding savings in energy and water costs, they also come with the burden of time and effort for the growers to…
