Final design for the tendering and construction management of mechanical, electrical and special systems for the redevelopment of the station complex Fs Garibaldi.
The design of the towers A and B is an example of the energy benefits obtained in this case from the redevelopment of an existing tower building destined to offices use, built in the 80s of last century. The project’s principles can, in fact, be summerised as follows: high performance building envelope, high energy efficiency, system choice with local “impact zero” emissions, winter energy certification class B ( obtained from a difficult situation ex ante being the existing building placed in class E ) and low running costs.
Sustainability elements that have found integration into the project are: interactive with active systems of attenuation of solar radiation in the cavity, bioclimatic greenhouses, use of renewable energy: recovery of geothermal heat through the removal of underground water as exchange fluid for termo-frigo-polyvalent reference groups; solar photovoltaic; solar thermal,type of heat recovery from the exhaust air enthalpy, secondary hydronic circuits of the variable-displacement air conditioning, pre-cooling outer parts air hygienic means of indirect exchange with groundwater, recovery of rainwater- with replenishment of water pumped groundwater in technological use – to power the toilet flushing WC designed ( dual network ), solar chimney ( exploitation of natural convection to the air extraction from toilets ), arrangements for the automation of artificial lighting, building management system ( B.M.S. ) that integrates in a single interface all management functions of the building ( HVAC, electricity and motive power, safety, etc. ).
Commissioning activities for the Tower B, aimed at the delivery of the building on the property under the defined conditions in the project and optimal operation for the well-being of the occupants, safety, maintenance and energy saving, achieved through analysis and assessment of technical documentation as-built mechanical installations, development of the commissioning plan, coordination of tests and measurements on site, technical supervision during adjustments, estimating the benefits obtained with the actions of commissioning, final report of commissioning, consulting for the development of the maintenance schedule.
The following phase of continuous commissioning aimed the energy monitoring through the design and installation of an Energy Management System,for maintaining the objectives achieved during the commissioning and monitoring performance and energy consumption.
