Summary

In order to mitigate climate change, sustainable and responsible use of resources is required. In the present study, different technologies applicable for the renovation of an office building are evaluated considering, both economic feasibility and environmental impact for the climates of Rome Stuttgart and Stockholm. Decentralized heating and cooling systems represented by different types of heat pumps (i.e. air-to-air On/Off and modulating) are considered in combination with photovoltaic panels (PV), battery and efficient lighting (LED) in order to investigate the achievable energy savings and the additional cost . The environmental impact is evaluated in terms of electricity and total primary energy (PE) savings calculated with constant and monthly conversion factors representing different scenarios with different share of renewables in the electricity mix. It was observed that the energy savings calculation method influences the ranking of renovation packages. High-energy savings with low additional cost are achievable with HP in combination or not with LED and PV, in Stockholm and Stuttgart, and with LED and PV in combination with electric heating in Rome. Battery brings additional energy savings with high additional cost.
