Melpet Farm Residences, Affordable Net Zero Ready
General Energy Use, Strategies and Systems
Energy Strategies:
The challenge of building energy efficient affordable rental housing involves per unit cost limits, motivating sub-contractors and effecting occupant behavior. The architectural details were reviewed by consultants for not only improved performance but for constructability and knowing the utility payment structure (the Owner pays all utilities in this case). All these factors defined the energy strategy.

Datasets and utility bills sources and reliability: The buildings are only recently occupied. The energy data from the VRF system is collected through a component of the system. There is a plan to monitor unit plug loads to collect and analyze the data and provide resident education if necessary.

Renewables and Energy Balance
Renewable Energy Sources: Renewable energy is generated within the building footprint (e.g. solar PV on the roof)
Renewable Energy System Description & Details
Because of the location in a historic district or an area controlled by the Old Kings Highway commission we were required to use an all black panel. Our first choice was the Sun Power 350 watt panel which would have generated more power but we ended up with the LG 300 watt panel. Our consultant managed to minimize the lower performance. Once the residences are occupied for a year we plan to evaluate the actual load versus the PV system performance and potentially add ground mounted arrays to fill any gap.
Annual renewable energy generated

300Watts
Photovoltaics
The PV system will be installed in March so to date our production data is estimated. We are expecting to export during the summer.
