To improve the energy efficiency of a building, a variety of energy retrofitting measures (ERMs) could be applied. By using simulation models such as eQUEST, the effect of each ERM can be estimated separately or as a whole. In this paper, an integration of a photovoltaic (PV) system and a combined heat and power (CHP) generator in an educational building located in Dayton OH was designed to conserve the energy consumption and reduce carbon dioxide emission, using eQuest and Homer models. Furthermore, some ERMs including, enthalpy wheel, natural ventilation, daylighting and overhang were adopted to the model to explore the optimum energy saving solution. The results showed that the PV-CHP integrated system with the all ERMs, might lead to a 32.5% reduction in the total energy consumption and annual carbon dioxide emissions. Besides, the total annual bill toward the retrofitting options was reduced up to 54%. The Homer model showed that 46% of the heating load of that building should be supplied by the CHP system and a standalone boiler may cover the rest. The investment required for applying the ERMs and the PV-CHP integrated system was $225,500 and the payback was 5.8 years.
