  • (1888PressRelease) January 24, 2012 - From waste ground to an attractive, futuristic district describes Milan's Via Stephenson zone, a north-west suburb close to the Expo site. It is an area that is rapidly changing and connects the old city to the new emerging Expo district. This area is populated with the new Certosa multiplex designed by architect Giancarlo Marzorati; the Alliance Insurance Group skyscraper and the new Boscolo BH4 hotel tower, again by Marzorati. The latter earned the prestigious Real Estate Award "Golden Brick" and "the best hotel and tourism project" of the year in June 2009.

    The tower, which rises to 91 meters, rests on a circular platform 44 meters in diameter. The total area of the facility is 145,000 square meters and is supported by reinforced concrete pilings that rest on vertical pillars, which rise from the reinforced concrete circular steel cast. The facades on all four sides are composed with coplanar blue-green glass surfaces and lined at different widths that are interrupted to allow for windows. The room comfort is achieved with high quality thermal and acoustic insulation, with double walls between the rooms and corridors, floors and ceilings are also insulated to the highest quality.

    Particular attention to the environmental and energy saving aspects characterize the structure. Thanks to a study of the building and the use of heat pumps combined with renewable sources, it has been possible to achieve an optimal energy performance for this building. Heat pumps take advantage of ground water using it to control temperatures in all rooms and for the production of domestic hot water, eliminating CO2 emissions. The units installed are two Climaveneta INTEGRA multi-purpose units - ERACS2 WQ-3202 and WQ-ERACS 1102 - a 4-pipe system suitable for the production of cold and hot water by two independent water circuits, with a total heat output of 2392kW.

    Each circuit operates with a semi-hermetic screw type compressor, R134a refrigerant and three shell and tube exchangers. One dedicated to cold on the system side, shared by the two circuits, which operates as an evaporator in the production of cold water. One is on the plant side and operates as a condenser to produce hot water. The third one is a source-side heat exchanger that operates as a condenser or evaporator according to the required loads.

    The wells that reach the first water take advantage of the return temperature. The use of heat pumps reach the temperatures needed for the primary fluid supply, both hot and cold depending on the season, and in this way saving a considerable amount of energy.

    The plant is designed to operate at low speed and low noise levels and is therefore able to work at partial loads without waste, even if the building is not fully occupied. The air conditioning in the rooms is provided by a traditional system, composed of primary air and fan coils, ensuring swift operation and functioning when the room is busy, saving even more energy.

    As said by Agostino Liuni, Alinvest CEO, "It is necessary to overcome the traditional speculative logic which requires a build that is economical as possible, but otherwise it is important to do it using the best technologies available on the market, to have a sustainable building that keeps its value over time".

    INTEGRA unit's installation improves the building's energy class and increases the present and future value of the property.
