ENGINEERED MULTI-UNIT HEATING AND COOLING ENERGY MONITORING AND COST ALLOCATION SYSTEM

摘要

In an aspect, a system is provided for determining an energy usage cost overa time period for a selected unit of a multi-tenanted building. The systemincludes a fluidmover for the selected unit, configured to operate at at least one pre-selected volumetricflow rate to deliver fluid flow to the selected unit; and a monitoring systemconfigured to:a) detect uses of the fluid movers and detect the associated flow rate;b) determine the duration of use of each fluid mover;c) determine an energy usage cost for the selected unit based on thedurations of use, on the flow rate associated with each detected use, on thedurations ofuse for the other fluid movers, and based on a total energy usage cost for allthe units ofthe multi-tenanted building; andd) indicate the energy usage cost for the unit for the time period.
