The goals of this monitoring plan are to develop a protocol for monitoring the SMUD DER GreenBuilt project and answer the following major questions:
- Are renewable energy systems performing as expected?
- Are energy efficiency systems performing as expected?
- Are whole house energy and peak cooling demand savings as expected?
- Is heat pump water heater performing as expected? What interactions are there with the solar hot water system?
- Based on monitored results, how can performance be improved in future retrofit projects?
Greenbuilt Project as a Lab Home The Greenbuilt house is to remain unoccupied and operate as a lab home until August 2010. Control and monitoring equipment installed in the home allows NREL to simulate occupancy patters and record the resulting impact on energy consumption. Automated controls include the operation of some lighting and electrical loads, activation of hot water use, simulation of internal heat gain loads and control of thermostat set points. Occupancy patterns are controlled by an automated program that can be updated and changed remotely. Some short term testing of equipment performance can also be accomplished remotely through the operation of control equipment.
Comparison of Monitored Performance to Expected Performance This monitoring plan will compare measured performance to the expected performance of renewable and energy efficiency systems. BEopt will be used to provide estimates of the expected energy performance for the monitored home. The retrofit solution will be evaluated to determine energy savings with respect to Title 24 and SMUD Baseline standards. Recommendations for improvements in the performance of future projects will be made based on monitored results.
Measurement of Energy Demand NREL monitoring activities will focus on evaluation of the energy demand of the major end uses that are being targeted by the SMUD ZEH program including site PV generation, space conditioning energy use (Heating, AH, and AC), hot water energy use, and total electric energy use.
Domestic Hot Water The Domestic Hot Water (DHW) system includes a solar hot water preheat system utilizing an Integrated Collector Storage (ICS), an Air Tap heat pump hot water heater and a 40 gallon storage tank located in the garage. The DHW system will be evaluated with long term measurements to determine its effectiveness at reducing electric use and what amount of energy is contributed by solar. Performance of the heat pump water heater will be evaluates both with and without the contribution of the ICS.
Control4 Home Energy Management (HEM) System In the GreenBuilt home, Control4 provides automated control of selected lights and electrical loads and thermostat settings.
