Passive Habitat

A Byzance Design passive house consumes 90% less heating energy than an existing building. And 50% less than a newly built house according to current thermal regulations (RT 2012). Regardless of its construction and geographical location, a Byzance Design passive house, with all the modern comforts, needs no more than 15 kWh per m² per year (1.5 liters per m² and per year). of oil equivalent) in heating.

Current passive achievements show that this definition is valid for regions with a harsh climate or a southern climate; the entire area between Madrid and Stockholm. A passive house costs between 10 to 25 euros per month in heating. This is significantly lower than a low energy house (between 40 to 65 kWh / (m²a), depending on the climate zone). And yet the comfort is much better!

For heating, passive house Byzance Design uses all available heat sources (sun, inhabitants, appliances, etc.). Extremely high insulation of exterior walls, roof and floor; as well as triple glazed windows allow to keep the heat inside. The fresh air is provided by acontrolled mechanical ventilation (VMC), double flow and inaudible (25db), which recovers heat from the outgoing air to warm the incoming air.

RT 2020

The RT2020 will implement the positive energy building concept all new housing built in 2020, also called "BEPOS" within the Sustainable Building Plan, these regulations will be objective regulations, leaving a total freedom of design, limiting simply energy consumption. Positive energy buildings are buildings that produce more energy (heat, electricity) than they consume. These are generally passive buildings that are very efficient and strongly equipped with energy production means in relation to their energy needs.

In the realization of positive energy habitats Byzance Design adopts the principles of the passive house, including in addition elements of energy production such as ventilation with heat recovery on stale air, reinforced thermal insulation, passive solar energy capture, high-quality windows, limited energy consumption of household appliances, rainwater harvesting.

Thus, walls, roofs, windows are used in the accumulation and return of heat or in the production of electricity. The surplus in energy is done thanks to bioclimatic and constructive principles but also by the behavior of the users who will limit their consumption. A study conducted by ADEME in June 2012 shows that for the hundred or so positive energy projects in France (65% in the tertiary sector, 29% in individual houses and 6% in collective dwellings) consumption is around 50 kWh / m2 / year, performance that can be further improved, making the 2020 goal of 3X20 possible, through the generalization of detection lighting and LEDs.
