The city of Dubai (UAE), in accordance with its program of transformation into one of the most smart and sustainable cities, hosted the 2018 edition of Solar Decathlon, the first in the Middle East (SDME 2018). The harsh climate of UAE, along with the booming construction industry and energy consumptions and CO2 emissions among the world's highest, tasked participating university teams to find innovative solutions able to drive the region building sector towards a more sustainable future.

The development of heat pump technology in the tertiary sector can lead to a reduction in greenhouse emissions and enhanced exploitation of renewable energy sources, including solar energy. The present paper investigates the potentiality of an energy system equipped with photovoltaic thermal (PV) hybrid solar collectors, a storage tanks for the heat source and a heat pump for the space heating of a small office located in three different European cities. The behaviour of the heat pump according to the heat taken from the photovoltaic panels and stored in the tank has been analysed.
