General Energy Use, Strategies and Systems

Energy Use:

embue Building Intelligence provides each owner with active building energy consumption and production data with a local and mobile interface.

No additional, special, or unusual energy systems or strategies were required.

Energy Strategies:

The primary energy strategy was to reduce all energy loads to about 1/3 the typical load and meet those with on site solar PV and thermal systems. The passive strategies include a highly insulated and airtight building envelope, passive solar gain, passive ventilation, and natural day lighting. Active systems include energy recovery ventilation and mini-split units for space conditioning and CFL and LED fixtures for lighting and Energy Star appliances.
