The Building
PalaCinema Locarno
The PalaCinema is a multicultural platform for the cinematic arts located in the historical centre of the city of Locarno in Ticino (Switzerland). The city hosts the Locarno Film Festival, so this centre is of particular importance. The Palazzo del Cinema Locarno project is guided by principles of economy, trying to capitalise in the existing structure and the public affection for the Palazzo Scolastico –which used to host the local schools and now hosts a variety of NGOs and community associations, to provide an architectural identity for the new cinema complex. This building is a landmark in the city. At a time when energy resources are dwindling and climate change has become a crucial problem for our cities, it would have been irresponsible to simply discard the existing building in order to build an entirely new one, with the corresponding expenditure of vital resources. Urban Recycling is a more adequate strategy for this intervention. Three levels of action to reduce the emissions have been considered: demand reduction, improved energy efficiency of systems and improved building management.

What is the Solution?
100% indirect Ground Water Heat Pump (GWHP) for heating/cooling and domestic hot water in combination with the solar PV plant in the roof of the building.
Why Does it work?
The production of thermal energy is guaranteed by a water-water heat pump with a primary medium of groundwater with 450 kW of thermal power capacity, while the refrigerating energy necessary for the air conditioning, of about 1'050 kW cooling power capacity, is ensured by a pumping station of water from the lake. In consideration of the fact that the lake water has a significant temperature difference depending on the seasonal trend and the depth of collection, in order to obtain an enough constant temperature and to allow an integral free-cooling function (10ºC at the point of use and 7ºC at the sampling point) it was necessary to go to a depth of 45 m due to the considerable length of the pipeline (approx. 1'000 ml.)
PROS
- Geothermal power can be generated throughout the year on twenty-four-hour basis as it is not much dependent on ambient temperature and weather conditions exploitation low enthalpy geothermal (aquifers) resources for heating and cooling.
- There is lower environmental impacts due to the exploitation of such geothermal resource.
CONS
- This solution presupposed an accurate analysis of various aspects such as:
- maintenance of the pumping station
- periodic cleaning of collection hoods
- housing and anchoring pipes
- operating pressures in the pipes
- power supply
