Owner approach of sustainability

Our work gives great satisfaction and urges the best virtues. "It always happens to me: first dream, then project, then build. In the end, I see people living inside my buildings, and it gives me satisfaction and pride to have it realized" We focus on a single energy carrier (electricity) by eliminating the gas that emits CO2 emissions.

Architectural description

The prestigious residential complex (class A), commercial and executive, consists of five buildings with a courtyard and green spaces. Edilvi has submitted the Borgo to architectural restoration work characterized by the respect of the original materials of prestige and the realization of elegant finishes of the highest quality. Throughout Italy, Borgo Meschio is the first complex with a bond of fine arts that has become a class A building through a restoration. The restoration was inspired by modern bio-building according to the criteria of sustainable building with the exploitation of renewable energies for Heating, refrigeration and hot water production. During the work, environmentally friendly materials such as wood-fiber insulation made of wood fiber and low-conductivated brickwork made of mineral-free mineral material are used. The beautiful blend between the architectural recovery of the old and the comfort of the most modern technology is able to ensure maximum efficiency from the use of clean and renewable energy, guaranteeing remarkable energy and economic savings but without sacrificing the spectacular design given by The historicity of the complex. Heating, cooling and conditioning of buildings and the production of sanitary hot water are carried out without the use of boilers, but through heat pumps. These are connected to 13 vertical geothermal probes and 81 energy poles, which drain free and renewable energy from the subsoil to a depth of about 100 meters. All our homes feature an induction hob and heating system with heat pump. This completely eliminates the need for a gas supply. The total absence of fossil fuels cancels the risks of any leakage and resets CO2 emissions into the environment. The heating in winter and the cooling in summer are distributed in the rooms through a plant with radiant ceiling, floor and wall panels. The system ensures a lower circulation of dust in the air and reduces the present humidity, saving considerable savings compared to normal wall radiators. Ceiling heating works as a result of irradiation and spreads heat in all directions. In this way, the differences in temperature between different areas of the room tend to be eliminated and a good thermal balance is created from the ceiling to the floor. The Aquapol wall drainage system prevents the environment from dampening. Thanks to the natural magnetic field released by the device, moisture moves slowly into the wall and returns to the ground. In this way the walls remain dry and only a residual natural moisture content remains in the air. The energy required for the operation of the power plant and the common parts of the Borgo is provided by a solar photovoltaic plant of 15.19 kW. For energy management, Edilvi's ESCo division deals with supply, energy efficiency, operation and overall maintenance of plants, with 24-hour emergency assistance. This allows for further tax savings on VAT on fuels, goods and services . Costs are accounted for individually based on the kWs actually required and supplied. The rainwater from the roofs is recovered and collected in an underground tank, filtered and connected to the irrigation system. This avoids the waste of drinking water and, above all, reduces consumption costs.

Building users opinion

In 2012, a customer satisfaction survey was sent to all users, with 40 multiple-choice questions and a score from 1 to 5 (from "Bad" to "Great"). The average of the ratings received was 4/5, in particular we received the highest votes in questions about interior comfort, material quality, and relationship with the site manager.
