ENERGY IMPROVEMENT OF BUILDINGS

ADDITIONAL STOREY OF A RESIDENTIAL BUILDING
An example in the Milan hinterland.
The project concerns the widening of a residential building site in the suburbs of Milan. The new volume has allowed the construction of a housing unit of 140 square meters, consisting of kitchen, living room, two bedrooms, a study, two bathrooms and a large terrace.
The load limits imposed on the existing structure have recommended the adoption of a structure made entirely of wood, with french roof and the walls closing in solid bricks.
A careful study of the details of construction has made it possible to form a continuous thermal envelope and free of thermal bridges, even at critical points such as floors, balconies and cornices. The thermal insulation in the roof is made of wood fibers, the walls were insulated with Stiferite, while on floor was built in a cork slab with high thermal and acoustic insulation.
The thermal casing was then completed with the predisposition of high quality wooden windows and double glazing safety, low emittance coating and argon gas: Ug = 0,6 W/mq k, Uf-value = 0.94 W/mq k, 38dB of noise isolation.
For the technological plants has been provided a plant for the Controlled Mechanical Ventilation with heat recovery (95% yield), production of heat with high efficiency condensing boiler, radiators and diffusion at low temperature, hot water production combined with condensing boiler and solar panels with an accumulation of 200 liters, electromagnetic induction plates to the kitchen, predisposition system multi split air conditioning.
The project has also provided an overall assessment of the energy balance of the building through the use of Cened Protocol, reaching the Class A, with a primary energy demand for heating of 24.24 kW h/mq a.
