Byzance Design is a reference in the construction and renovation of passive housing or meeting the criteria of RT 2020. We provide personalized assistance from the design of your project to the choice of materials for different spaces such as the kitchen, the bathroom, and the bedrooms. Your expert in construction and renovation also realizes villa renovation, an extension of a traditional house, renovation of a wooden frame house, etc.

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 (which is 1.5 liters per m² and per year 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 keeping the heat inside. The fresh air is provided by controlled 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 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, the 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.

Thanks to its Préfabéton factory in Pontarlier, Byzance Design enjoys affiliation with the French Federation of Passive Construction (FFCP)

Precast concrete and wooden frame constructions : Exclusive eco-friendly construction systems 

Byzance offers high end precast concrete constructions, quickly and at very competitive prices.

Byzance Design is the exclusive distributor of the Magmur building system: prefabricated concrete walls with insulators and integrated electrical ducts. A process developed by the company PréfaBéton. Ultra-resistant, natural, local, non-polluting, 100% recyclable, with a high thermal inertia ... After analysis and contrary to popular belief, concrete cultivates its qualities and erases its defects to meet the challenge of sustainable construction. Thanks to many technological innovations, the most used material in the world is becoming more and more ecological. Particularly involved in the development of constructive modes respectful of the environment, Byzance also develops a new wood offer for the residential ...

The advantages of our concrete and wood prefabricated construction systems :

/ The very competitive quality / price ratio of concrete and wood materials is related to the production environment in which they are made. Indeed, this framework reduces the number of errors, the amount of waste and therefore the costs.

/ Reduced construction time on site also reduces labor and travel costs.

/ The temperature control, the specialization of the workers and the appropriate situation of the site have a favorable impact on the quality. Thus, our prefabricated elements meet all the main national and international standards.

/ With a UPC coefficient of less than 0.20, our products are extremely efficient both in summer against heat and winter against cold. They are also part of the RT2020 and passive habitats. The savings on the heating balance can go up to 80%.

/ The supporting structures do not require any maintenance.

/ Our prefabricated solutions are flexible and modular.
An extension or a possible transformation of a prefabricated house will be without problems and can thus adapt to the needs of the moment, and grow according to the increase of the family.

/ Quality is also reflected in other characteristics of our prefabricated materials, such as shape retention, dimensions and properties, as well as weather resistance.

/ Our materials are CO2 traps: the gas in the air enters the wood and concrete through the porous network and, in the presence of water in the concrete, is fixed in calcium carbonate. A lifelong phenomenon of materials that helps reduce their carbon footprint.

/ Unlike traditional building materials, wood and prefabricated concrete are materials whose revaluation or recycling is considered without harm to the environment.
