Buildings, HVAC and comfort

Simplified heat and moisture balances; site-specific assumptions.

areas, U-values, indoor/outdoor temperatures → design conduction heat load

air exchange, building volume, temperatures → sensible heat load

heat-loss coefficient, degree days, system efficiency → seasonal energy estimate

envelope, solar gains, people, equipment, weather → screening cooling capacity

heating/cooling demand, COP curve, temperatures → electrical demand, heat delivered

temperature, relative humidity, pressure → dew point, humidity ratio, enthalpy

air state, surface temperature → dew-point margin, condensation condition

water volume, temperatures, heater efficiency and power → energy, reheat time

airflow, temperatures, sensible effectiveness → recovered heat, remaining heating load
