INNOVATION ZERO IMPACT

Innovation and sustainability for the new headquarters Nuncas: the first building that generates its own energy. The headquarters, a new plant in Settimo Milanese, avant-garde in Italy and Europe for its advanced technology and architectural solutions and techniques employed, was deliberately designed by the engineer Luca Manzoni to have a minimal environmental impact, like all Nuncas products. It is self-sufficient in energy by using solar panels, uses eco-friendly materials and is an example to be copied as far as home automation, ventilation and natural lighting. All this has allowed Nuncas to win the prize Ecohitech Awards 2009 for the category "Companies eco- virtuous." The commitment of Nuncas is also visible in the study, design and manufacture of products that respect the environment and the health of the client. It starts from the raw materials, carefully selected by the Research and Development sector, according to the criteria of non-toxicity and high quality, to eliminate anything that appears to be particularly dangerous or polluting; it goes on with the basic ingredients of fragrances, natural, hypoallergenic, until the bottles, no more PVC (polyvinyl chloride ), but in PE (polyethylene), a more eco-friendly plastic, which assures a lower impact on the health of workers who work the plastic material at high temperatures. Finally, the cartons used for packaging are made from recycled paper.

Mechanical plants

The project involved the installation of a ground water heat pump system that feeds the circuits of the radiant panels and primary air. The reversible ground water heat pump is able, in winter, to absorb heat from the ground water and, in summer, to release the heat. The summer yield (COP) is 3.5 while the winter yield is 4.5. The COP of heat pumps in fact depends on the temperature difference between the cold and hot source. The summer and winter air conditioning of the building is achieved by means of low temperature radiant ceilings and an air handling unit where the exhaust air extracted from the rooms crosses in countercurrent with that sucked in from the outside in order to recover the heat. in winter and cool in summer. The radiant panel systems of the offices and the warehouse are powered by low temperature water to make the best use of the heat pump and condensing boiler serving the warehouse. The panels used have a vast thermal inertia as they are detached from the structure of the floors, thus allowing the system to be completely switched off at night. In addition, to reduce heat accumulation in the summer season and the need in the winter, panels fed by groundwater were installed between the insulating material of the roof slab and the flooring of the roof itself.

Opaque, transparent casing and lighting

The new Nuncas Italia headquarters is located in the municipality of Settimo Milanese and was built in 2007. In the building intended to house offices, the supporting structure is made of reinforced concrete covered with a layer of insulating materials, on the outside of which there is a air gap and an Alucobond®-type aluminum cladding. This stratigraphy achieves a transmittance of 0.49 W / m2K. The coverage is more performing guaranteeing a transmittance equal to 0.26 W / m2K. The windows and doors are composed of an aluminum frame with thermal break and low-emission double glazing of the Klimaplus4s type. The transparent envelope is equal to 2.31 W / m2K The windows can be darkened with automatically operated external blinds and with adjustable metal slat blinds inside. In winter the external solar curtains are raised to allow the passage of solar radiation inside the rooms, while in summer they are lowered to avoid overheating phenomena. The strategies regarding the lighting systems are aimed at maximizing on the one hand the efficiency of the artificial lighting and on the other the exploitation of the natural lighting of the environments. Environments without windows are also illuminated directly by sunlight through a system of light fireplaces. The light detectors placed on the roof capture the natural light which is then transferred to the interior and diffused into the room itself. The lamps are low consumption with automatic ignition with presence detector and with variable adjustment of the artificial light intensity based on natural light conditions.

Renewable energy sources

624 photovoltaic panels have been installed on the roof, whose total nominal power is 134 KWp and the annual production in the project 154000 KWh. The panels are made of monocrystalline silicon and have an orientation of 11 ° SOUTH / EAST and an inclination of 30 ° with respect to the horizon. The total absorbing surface is 811 square meters. 6 square meters of solar thermal collectors were also installed on the roof to produce hot water for sanitary use.

Forest Bomb

Forest Bomb was born in Nuncas from the desire to celebrate our centenary, which took place in 2020, by planting a tree, symbol of the future, sustainability and growth. This will meets Pietro Zucchetti, president and founder of the Italian Permaculture Institute, an expert supporter of resilient and sustainable projects, and with him, what was originally just a tree, has become a real edible forest, right in the garden of the headquarters of Seventh Milanese. Permaculture is a set of practices that allow the cohabitation of man with all of creation, be it animal, vegetable and mineral, to continue in a continuous, sustainable and resilient manner. The Forest Bomb is therefore an ideal symbol for Nuncas and his 100th anniversary, since, like the company, it will grow every day, projecting itself into the future, but sinking more and more roots into the ground for stability and nourishment.
