La Valentina North presented a valuable opportunity to explore the actual performance of low-rise multi-family design strategies that produce deep model-predicted energy savings. This research aligns with broader utility and state goals to move buildings towards ZNE use.
TRC monitored six dwelling units, representing at least one of each of the four types of units at the property. Electric end-uses were monitored via a remote, web-enabled system called eMonitor. Thermostats that communicate wirelessly with the eMonitor system were installed in each monitored unit.
We reviewed the monitored data to report on actual energy use as compared to predicted energy use by unit as well as average use for the building. Overall, results demonstrated large variations in energy use by unit—largely driven by the use of air conditioning equipment. Plug loads and appliances constituted a large portion of the overall energy use, which was relatively constant throughout the year.
As a result of the study, we were able to:
