Home energy efficiency standards in France
To try to understand the rules, you'll also learn not quite a few RT2005 strange hieroglyphics – BBC QEH THQE – so we thought a quick tour of the different labels and the basic standards established by each may be useful.
The RT2005 is the minimum standard for energy efficient new homes, replacing the model Previous RT2000 called.
The full description is Thermal Regulations 2005 and applies to all new buildings, where the planning application was submitted after September 1, 2006.
The standard defines a maximum level of energy requirements for Housing, expressed in quantity of energy consumption kWh / m2 per m2 per year, or year (kilowatt / hour per square meter per year of energy primary). In general, the classification measures the energy loss through the building envelope. The lower part of the kWh/m2, the more energy is building.
For residential properties in the standard RT2005 kWh/m2 between 150-230 per year, depending on location geographical property, including its altitude.
High Energy Performance – HPE 2005
To obtain Standard HPE needs of energy consumption must be at least 10% below established in RT2005.
The standard covers a performance analysis comprehensive housing around the heating, hot water, air conditioning, ventilation and lighting.
In the standard there is also HPE HPE Renewable Energy (ENR HPE) in 2005, where at least 50% of heating should be from renewable sources.
Build the old houses between January 1, 1948 and January 1, 1975 are also capable of obtaining high energy efficiency standard replacement (HPE renovation 2009).
The standard set of global energy for homes and is a bit more generous than for new dwellings, 150 50 kWh / m2 per year, depending on location and altitude.
Curiously, it does not seem to model energy for homes built before that date, and because 1948 was chosen as the threshold, it is probably known only by technocrats who drafted the law.
Very High Performance, Energetics THPE 2005
To achieve this standard, the overall level of energy consumption must be at least 20% below RT2005. This would give an energy rating of 90-150 kWh / m2 per year depending geographic location and altitude of the property.
Once again there is a renewal model of energy with THPE mimumum with 30% of energy from renewable sources.
Construction of a property for grants THPE standard fee increase field density (coefficient of land use) in 20%.
Low Consumption Building (BBC)
To achieve this level of energy consumption must be less than 50 kWh / m2 per year, varied the location and altitude for 40kWh/m2 65kWh/m2.
Construction of a property to the standard BBC grants the right to increase the density of the plot (coefficient of land use) of 20%.
Existing dwellings built between January 1, 1948 and January 1, 1975 may also obtain the standard Low Energy Consumption Building Renewal (Renovation BBC 2009).
Standard Globel all energy for households because it is a bit more generous than for new housing in 50-80 kWh/m2 year.
A certificate of quality to meet the standard BBC award for 'Effinergie, the French agency for higher standards of low energy consumption.
The RT2012 and RT2005 replace the equivalent the BBC.
In 2020, the housing must be built with a pattern that makes energy neutral or positive.
Grants and tax credits for energy conservation
There are grants, interest-free mortgages and tax incentives available for measures of energy conservation, which can be viewed on our guide to home energy savings in France.
The rules do not always need a certain level of energy performance is achieved in particular with tax credits that are available, although in all cases, there are rules on the level of performance of materials and equipment to use.
In other case, you will typically required for energy performance audit conducted, with an assessment of the expected benefits of the work.
