The rapid economic growth of United Arab Emirates (UAE) over the past three decades has triggered the construction of a large number of commercial buildings such as hotels, which consume a massive amount of energy and water, especially when compared to hotels in other countries.

Based on the results of the audit process, the best energy efficiency action was chosen: a Heat Pump instead of a Steam Boiler was proposed in order to solve the low temperature loads.

Abstract
The rapid economic growth of United Arab Emirates (UAE) over the past three decades has triggered the construction of a large number of commercial buildings such as hotels, which consume a massive amount of energy and water, especially when compared to hotels in other countries. Hence, the necessity of improvement of the energy performance in this sector to reduce the carbon emission would be very high. The paper deals with an Energy Efficiency intervention in an important Hotel in Abu Dhabi. The Intervention started doing an audit aimed at documenting the usage of diesel fuel in the building’s thermal processes in order to study a set of strategies intended to mitigate fuel consumption and the associated costs. Based on the above purposes, the root generation and distribution network of thermal loads within the facility (Boiler/Steam network) were identified and the network’s architecture as well all the points of demand, from appliances to thermal exchangers, were analyzed. Therefore, the desired outcome of this exercise was the proposition of energy saving and retrofitting strategies along with their energy savings estimation. Based on the results of the audit process, the best energy efficiency action was chosen: a Heat Pump instead of a Steam Boiler was proposed in order to solve the low temperature loads. Finally, the baseline to calculate the energy and cost efficiency was defined and the intervention was carried out with a financial partner and the post-operam monitoring is still in progress.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
