The impact of microturbines and PV systems of office buildings in energy-efficient, economical, and environmental aspects

Net-zero energy buildings can maximize electrical and thermal energy efficiency as they use renewable energy resources, particularly combined heat and power (CHP) systems and photovoltaic (PV) systems in this study. Therefore, the objective of this study is to present a demand response study for analyzing the impact of CHP and PV systems of small-, medium-, and large-office buildings in energy-efficient, economical, and environmental aspects. Then, each case study of small, medium, and large office buildings hosting CHP and PV systems in the Atlanta area is simulated. Finally, their energy-efficiency improvement and economic sensitivity analysis on investment costs are presented.
