Assessment of economically feasible net zero energy building concepts using the example of an office building in Germany

Scope of this paper is the evaluation and assessment of a net zero energy building concept in respect of functionality and economic feasibility. The analysed energy concept is based on air source heat pump technologies, a mechanical ventilation system and a photovoltaic system. The evaluation work comprises the monitoring of the described building energy concept, a parametric study on economically feasible improvement potentials as well as a comparative study on alternative energy supply solutions.
