For its efforts in the realization of this building, the Municipality of Cologno Monzese officially reached the status of Partners of the GreenBuilding Programme. During the design and construction phases, the Municipality was supported by the technical partner Rockwool, particularly in regards to the thermal insulation material and systems. For its support to the project, the company Rockwool became Endorser of the GreenBuilding Programme. Both the Municipality and the technical Endorser Rockwool were awarded at national and european level, during the GreenBuilding Awards in 2010.
The building owner and the endorser were supported by the end-use Efficiency Research Group of Politecnico di Milano (eERG-PoliMI), as National Contact Point in Italy for the GreenBuilding Programme.
Description of the ENERGY CONCEPT and the building
The building´s function is that of a kindergarten for approximately sixty children and a civic centre for social and cultural activities for families. The school and social structure was ordered and will be managed by the Municipality of Cologno Monzese, in the suburbs of the Milan area, in the north of Italy. The main volume of the intervention is a new building, whose architectural shape is quite unconventional and very attractive. It has curved roof surfaces - which contribute to the overall organic feeling. The aim of the architects is to create a building with functional internal and external spaces (classrooms, multipurpose spaces, gardens, offices and rooms for employers, etc.) and has an interesting appeal for children and family of the community. Building envelope has a high thermal insulation level, both for opaque and transparent surfaces. In the summer period, solar gains are reduced by an adequate shape of the roof surfaces on the south exposition, and by the presence of vegetation in the garden on the West. A mechanical ventilation system is installed, with high efficiency thermal recovery devices and the possibility to adopt night time mechanical ventilation in the summer. Great care was used to choose a high efficiency heat pump for heat production, with a water heat exchanger from the ground. In summer, free cooling is adopted, by using a ground water heat exchanger, and a high temperature floors radiant cooling system. A good part of electric consumption of the building is covered by photovoltaic panels, installed on the roof of a nearby building.
BUILDING ENVELOPE, PLANTS AND CONTROLS
Opaque building envelope
External walls, roof and ground floor are built with thermal resistance higher than required by legislation. In particular, maximum adopted values are:
Light coloured, metallic covering roof surfaces
Windows and transparent parts of façades
Transparent surfaces are built with thermal resistance much higher than required by legislation.
Windows – all types (triple pane, argon filling, Low-E):
Skylights cover 1,5% of roof area and are positioned over rooms located in central part of the building volumes (such as offices, service rooms) in order to deliver natural light (daylighting) to these spaces.
(triple pane, argon filling, Low-E):
The artificial lighting plant is composed almost entirely of fluorescent tubes powered by electronic ballasts. Exceptions are limited to the high profile reception areas.
ENERGY MANAGEMENT STRATEGIES
The main basis of the Municipality’s energy management plans are: to establish clear rules for the procurement of energy using equipment, clear goals for the energy team (an energy team appointed by the Municipality will guarantee the achievement and maintenance of the level of performance foreseen at the design stage), periodical maintenance activities on heating and cooling plants, ventilation system and lighting devices are all included in order to guarantee both health and safety conditions and energy performance in the buildings.
