Energy balance

His home energy reviewenergetique

A new thermal regulation is in force. Among the novelties, carry out a diagnosis of thermal performance of real property.

Since 1 November 2006, the diagnosis of the Energy Performance of buildings (DPE) part of the mandatory documents to be attached to the contract of sale of a dwelling (and, effective from 1 July 2007, any new contract). It has only an informational value, but it must establish the thermal characteristics of housing.

That takes into account the DPE :

  • The respective share of renewable and fossil energy.
  • The consumption of all heating and cooling positions.

The estimation of heating greenhouse gas emissions, the production of domestic hot water and cooling… The use of renewables is widely encouraged, Similarly the bioclimatic architecture (summer and winter comfort).

The House of the future ?

Today, the standards that define a passive house are called to become the European standards. Specific criteria necessary do not exceed certain levels in heating, sealing air and primary energy consumption.

To go even further and closer to home 100% autonomous, There are specific facilities… Wind turbines, solar panels, heat pumps, Canadian wells, dry toilets, recovery of water and solar ovens are just some examples of alternative solutions to our existing systems.

Thermal regulations 2020

On the horizon 2020, It is envisaged that the RT 2020, who will implement, the concept of positive energy building (BEPOS). These future regulations are regulations of objectives, they leave design freedom while limiting energy consumption. A positive energy building is a building that produces more energy (electricity, heat) that it uses for its operation. This difference in consumption is generally considered over a period of one year.

If the period is very short, We speak rather of autonomous building (electricity is easily storable over several months). It is usually a passive building high-performance and highly equipped with the means of energy production over its energy needs. The roofs, walls, even windows or other elements (canopies of veranda or balcony, walls, garage or shed roof, foundations, etc.) can be used to accumulate and render the heat or produce electricity.
