UTENJA aims to support thermal energy networks and promote new jobs in the decarbonization sector for residents.

Figure 3: An energy recovery ventilator unit installed at an administration building in Massachusetts. The ventilator exchanges heat between outdoor air and ventilation from occupied spaces. It operates in air economizer mode when the outdoor air temperature is below 60°F and modulates the outside air damper and return air damper to maintain the mixed air temperature set point.

Homeowners of a high-rise building wanted to install chargers throughout their underground garage and wanted to do so without changing the risk profile of their building. The homeowners association (HOA) of an existing high-rise condominium building would like to install Level 2 electric vehicle (EV) chargers for half of the parking spaces in their underground parking garage. They are concerned that if they provide a high density of chargers, they will increase the risk to their building.
