GreenLab Project

GreenLab Project

A global benchmark for Green Technology

Kerakoll GreenLab is a leading centre also from an architectural point of view, an engine of growth and sustainable development where natural construction materials represent the element generating sustainable architectures and increasingly smart buildings. A highly innovative project of strong impact on European industrial culture where the real value of the GreenBuilding, a building-icon of sustainable architecture, can be perceived.

The study and development of innovative solutions in the context of bio-building are the fundamental pillars of the Kerakoll GreenLab project which combines elements of structure sustainability in terms of bioclimatic and energy efficiency (class-A building), high quality of interior spaces at the service of researchers linked to the perceptual as well as relational aspects of architecture. The intervention contemplates the use of natural, breathable and ecological construction materials produced directly by the company. The home comfort of working environments is guaranteed by constructive choices and materials used, and improves the microclimate and the quality of "indoor" air, by virtue of natural ventilation and the green system, to provide natural lighting through control systems and advanced optimization, also taking into account the principles of colour therapy and natural heat equilibrium.

At the end of 2010, Kerakoll GreenLab won the Legambiente GreenLife Award for Environmentally Friendly Innovation, a prestigious national recognition for company innovation in the environment protection sector. It was also selected to participate in the Italian Pavilion of the 13th Venice Architecture Biennale (Aug/Nov. 2012) as a bona fide example of the care and attention to the workplace that iconic Italian company Olivetti was renowned for, and the theme of this year's exhibition.

The solutions involve clear advantages in terms of

Energy Saving:

> Heat insulated walls (Thermal block - Biocalce® Termointonaco - Biocalce® Silicato Puro Pittura).

> High thermal insulating glass with the insertion of special blades for the reflection of thermal radiation and the diffusion of light inside the building.

> High insulation roof made of laminated wood. The coating of the cover made entirely with Kerakoll innovative technologies marked the "Cool Roof" effect with very high solar reflectance and thermal emissivity which naturally guarantee less heating of interior spaces.

> A photovoltaic system consisting of a plant of 208 panels for a surface of 280 square metres which can produce up to 16 KW of electrical energy was built to shade the facade.

> Building Automation:
sensors to check internal light levels, topping up natural light with artificial light as necessary; presence sensors are fitted throughout. The Building Automation system controls and manages: the climate control, lighting, alarm system, climatic chambers, access control, irrigation system.

> Geothermal: 9 geothermal probes at a depth of 100 metres each cover 65% of winter and 50% of summer heating requirements. The geothermal energy system combined with the Radiant Panel heating system provide high efficiency energy saving.


> Metal structure and wooden roof recyclable at the end of its life cycle.
The wood used is PEFC certified, Programme for Endorsement of Forest Certification Schemes, for the implementation of sustainable forest management.

> Exclusive use of Kerakoll materials,
natural, breathable and extremely low emissions for the construction of outer and inner parts of masonry walls – flooring – waterproofing and bonding of the covering made with Trencadis.

372 tons of materials of which 127 tons of recycled materials, 255 tons of local materials were used to build these elements. Of these 372 tons. 314 are recyclable at the end of their lifecycle 58,695 kg of organic base products that contained only 348 kg of solvent (less than 1%) were used as well.

> Natural lighting
of the environments is guaranteed and glare is prevented by light entering from above through the large skylight, sun tunnels in the roof, and windows fitted with adjustable blades to carry and control light.

> Recovery of rainwater
from the roof with vegetated filtration system. Recovered water is used for irrigation and for replenishing the water in the tanks lost by evaporation.

> Recovery of waste water
for toilet and dressing rooms. Treatment of biological purification with UV ray disinfection. Reintagration in the cassettes. Savings of 30% of water used in toilets.

> Rainwater is collected via a vegetated filtration system
and reused for irrigation and to fill bioclimatic cooling tanks. SUDS-Sustainable Urban Drainage Systems are also used for purification, water level control and slow infiltration of surface water into the ground.

> Bioclimatic:
built along the north-south line, glazing on the southern facing side of GreenLab absorbs the sun’s heat energy while heat loss is minimised on the window-less north-facing side. Micro-climatic control is favoured by internal and external landscaping, glazed photovoltaic panel screens, and water tanks.


> Indoor pollutants: the majority of the materials used have very low volatile organic compound emissions (VOC) and so guarantee a healthy working environment with no risk of sick building syndrome. The 5 principal indicators of indoor pollution are monitored live inside the building referring to the European commission Index project made in collaboration with the Joint Research Center with results that are far below the average levels recorded in European buildings.

> Allergens, bacteria, mould and mildew:
almost all the products used are certified bacteriostatic and fungistatic by the French CSTB authority with effects, that even in this case, are positive on the health of the workplace. Even the bacteria and mildew are monitored with results far below the standard limits.
