Eight H1a, H1b, H1c, H2a, H2b, H2c, H2d, H3 are defined in annex I to this Order.
Three classes of exposure of buildings to noise from transport infrastructure BR 1, BR 2 and BR 3 are defined and determined in accordance with the terms of Appendix II to this Order.
The terms necessary for understanding this Order are set out in annex III.
The building is called the initial building as it exists before the rehabilitation work. The building is called a project building as designed following the renovation work.
The conventional energy consumption of a building for heating, cooling, production of sanitary hot water, lighting, and auxiliaries for heating, cooling, hot water and ventilation, is expressed as a coefficient expressed in kWh/m2 of primary energy, noted Cep. This coefficient takes into account a possible production of electricity to remain in the building.
The area taken into account is equal to the non-network floor area within the meaning ofarticle R. 112-2 of the urban planning code.
This coefficient is calculated for a period of one year by adopting conventional climate data for each climate zone, according to the calculation methods defined in the TH-C-E ex calculation method approved by an order of the Minister in charge of construction.
Cepinital and Cepproject respectively note the conventional energy consumption calculated for the original building and for the project building.
The reference consumption of the building is called in the project and is noted This prefects the conventional energy consumption of the project building, calculated on the basis of the reference characteristics given in Title II of this Order.
The conventional indoor temperature reached in summer, noted Tic, is the maximum hourly value during the period of occupancy of the operating temperature; for residential the period of occupation considered is the entire day. It is calculated by adopting conventional climate data for each climate zone.
Tic's calculation methods are defined in the TH-C-E ex calculation method approved by a Minister's Construction Order.
Conventional reference internal temperature is called and Tic refutes the conventional indoor temperature reached in the summer, determined on the basis of the reference thermal characteristics given in Title II of this Order.
There are two categories of premises in respect of summer comfort and cooling, named CE1 and CE2, and defined in Annex III.
1. Is considered to satisfy this thermal regulation any project building for which the construction master is able to show that the following conditions are met simultaneously:
1° The conventional energy consumption of the initial Cepinital building is estimated using TH-C-E ex, in accordance with the terms specified in Article 14 of this Order;
2° The conventional energy consumption of the building in the Cepproject project is less than or equal to its reference consumption Cepref;
3° For buildings in residential projects, conventional energy consumption for heating, cooling and production of sanitary hot water, expressed in kWh/m2 of primary energy of the building in project, is less than or equal to a maximum Cepmax coefficient, determined in the manner specified in Article 13 of this Order;
4° For non-residential project buildings, conventional energy consumption of the Cepproject building is less than 30% than the consumption of the original Cepinital building, estimated as 1 (1°) of this article.
5° The minimum requirements set out in Part III of this Order are met.
6° For areas or parts of CE1 category areas and for each of the project areas defined by its use, the conventional internal temperature of the Tic zone is less than or equal to the conventional internal reference temperature of the Tic ref area. This requirement can also be met by considering each part of the building areas for which Tic and Tic ref tower are calculated; If the calculation leads to a value of Tic ref below 26 °C, Tic ref is then equal to 26 °C.
This requirement does not apply to areas comprised of EC2 class premises.
2. Project buildings whose construction products and their implementations are deemed to be in compliance with the technical processes and solutions approved under the conditions described in Part IV of this Order are deemed to be in compliance with the regulations.
For the purposes of Article 12, the values of the maximum Cepmax coefficient are given in the following table:
| Fossil or wood fuels | H1 | 130 |
| | H2 | 110 |
| | H3 | 80 |
| Electric heating | H1 | 165 |
| (including heat pumps) | H2 | 145 |
| or Heat Network starting January 1, 2010. | H3 | 115 |
| Electric heating | H1 | 195 |
| (including heat pumps) | H2 | 175 |
| or Heat Network until December 31, 2009. | H3 | 145 |
In the following two cases, by derogation from 1 (1°) and 1 (4°) of Article 12, it is not required to evaluate the Cepinital consumption and, for non-residential buildings, the consumption of the Cepproject building must not necessarily be less than 30% than the Cepinital consumption:
― renovation work is accompanied by a change of use within the meaning of the TH-C-E ex method;
― or the entire pre-renovation building was not used, or heated or cooled.
The other provisions of section 12 apply.
The workmaster must be able to justify any value used as input data for the calculation of the Cep and Tic coefficients in accordance with the TH-C-E ex calculation method:
where products are subject to application Decree No. 92-647 of 8 July 1992 modified with respect to the suitability of the use of construction products, the products identified in this case by the affixing of the CE mark, and that the latter includes the thermal characteristic, the justification of this value is provided by reference to the harmonized standards or European technical approvals;
otherwise, the characteristics of the products are justified by reference to French standards or equivalent technical advice or national standard accepted by a member country of the European Union or contracting party of the EEE agreement, and are issued by an independent third party body notified under Directive 89/106 recognized by a member State of the European Community or a Contracting State of the Agreement establishing the European Economic Area. The benefit of this provision is only valid during the period preceding the application of a harmonized European standard or European technical approval.
In the absence of the power to justify a value of the thermal characteristic of a product under these terms, the value to be used is specified in the TH-C-E ex calculation method.
With the exception of buildings whose construction products and their implementation are in accordance with technical processes and solutions, the construction master shall make the description of the data used for the calculation in electronic format, according to the model defined in the TH-C-E ex calculation method.
The master also prepares, at the latest, a synthesis of thermal study according to the terms specified in Annex VI.
Inertia
The reference daily inertia is determined by inertia prior to renovation work using the TH-C-E ex method. If the inertia before work is light or very light, the reference inertia is equal to the inertia of the building before work. Otherwise, the reference inertia is medium.
The reference sequential inertia is very light within the meaning of TH-C-E ex.
Surfaces and wall orientation
For the calculation of Tic ref and Cepref, the reference bay surfaces are those of the project.
However:
― where the renovation works provide for the installation or replacement of the entire curtain façade such as the bay surface is greater than 50% of the façade surface, it is considered to be 50% of the façade surface for the reference building calculation. The considered front surface is equal to the sum of vertical wall surfaces in contact with the outside or with a non-heated space;
― where the renovation works provide for the replacement of the entire cover of a high floor, the surface of the reference horizontal bays has a maximum limit of 10% of the total surface of this floor.
Surfaces above these thresholds are considered opaque walls and are added to them.
For the calculation of Tic ref and Cepref, the reference bays are those of the project building.
Thermal deflections by transmission through the walls and bays of a building are characterized by the average thermal depletion coefficient of the building, called Ubat, expressed in W/(m2.K), and determined in the TH-C-E ex calculation method.
The reference thermal deflections are calculated with dimensional characteristics A1 to A7 and L8 to L10 of the project defined as follows:
A1: surface of vertical opaque walls, including the vertical walls of the fitted panels and projected surfaces of roller shutters not integrated into the bay, with the exception of opaque surfaces taken into account in A5, A6 and A7;
A2 : surface of high floors and roofs other than those taken into account in A3 ;

L9: linear of the peripheral link of the intermediate or sub-alloyable floors with a wall;
L10: linear of the peripheral link with a wall of high concrete, masonry floors or with ribbed metal plates.
The surfaces of vertical opaque walls and bays take into account the specifications of Article 18.
A1 to A7 surfaces are the inner surfaces of the walls and linear L8 to L10 are determined from the inner dimensions of the premises. Only, for the determinations of these surfaces and linear, are taken into account the walls or connections giving on a heated space, on the one hand, and on the outside, an unheated space, the ground or a sanitary vacuum.
The surface to be taken into account for doors, windows and windows is the table.
In case the peripheral link of a floor is at the junction of an intermediate floor with a low floor or a high floor, the linear to be taken into account is L8 or L10 respectively.
The values of the reference thermal transmission coefficients a1 to a10 corresponding to the dimensional characteristics A1 to A7 and L8 to L10 are given in the table below:
| a1 (W/m2K) | 0.36 | 0.40 |
| a2 (W/m2K) | 0.20 | 0.25 |

For the calculation of the Cepref coefficient, berries are equipped with mobile protections such as the solar factor and the luminous transmission rate are 0.40 in open position and 0.15 in closed position.
For the calculation of Tic ref the reference solar factor of the berries is defined in the table below, depending on their exposure to noise, orientation and inclination, as well as the climatic zone and altitude. The reference luminous transmission factor is taken equal to the reference solar factor.

The reference solar factor for opaque walls and peripheral connections is 0.01 for the calculation of Cepref and 0.02 for the calculation of Ticréf.
Air permeability under 4 Pa of the exterior envelope of the building referenced and reported to the surface of the envelope is equal to:
1.7 m3/(h.m2) for residential or office buildings, hotels, catering and teaching facilities as well as sanitary facilities;
3 m3/(h.m2) for other uses.
For buildings with different areas of use, the reference value is calculated on average weighted by the useful surfaces of the areas as defined in the TH-C-E ex calculation method.
The surface of the envelope referred to in this article is the sum of the A1 to A7 surfaces referred to in Article 21, excluding the surfaces of the low floors (A4).
The reference ventilation system is such that the same outdoor air is used to ventilate the contiguous or separated premises only by traffic, within the limits of existing regulations.
For residential premises, the reference system is a system by air extraction taking air directly outside, the sum of the modules of the air inputs is 90% of the maximum flow value resulting from hygiene regulations.
The flow rates to be recovered are equal to the minimum flow rates resulting from hygiene regulations or, if not, conventional specific flow rates defined in TH-C-E ex rules, plus the Crdb flow rate control coefficient equal to 1, and the overflow factors taking into account the uncertainties associated with the characterization of the mouths and leaks of the Cd aerallic network equal to 1.1 and Cfres equal to 1.
The extractor mouths located in the kitchen are at two flow rates and equipped with a manual flow management device. The other mouths are flat-rate.
The reference power of the Pventref fans is 0.25 watt per cubic metre and per hour of airflow per fan. This value is ranged to 0.40 if the installed system is equipped with a Class F5 to F9 Insufficient Filter. Powers are calculated for hygienic rates increased by 10%.
For residential premises heated by Joule effect, the reference ventilation system is a system of modulation of ventilation flows to reduce by 25% the energy depletion due to the specific ventilation, calculated on the basis of articles 26 and 27.
For other residential premises, the reference ventilation system is a system of modulation of ventilation or heat recovery flows to reduce by 10% the energy losses due to the specific ventilation calculated on the basis of articles 26 and 27.
For all of these premises, the impact of the reduction of the flow from the flow through the leakage defects is taken into account in the calculation.
For non-residential premises, the reference system is a system by insufflation and air extraction without heat exchanger and without fresh air preheating and whose incoming and outward flow rates are equal. The flow rates to be supplied and taken back are equal to the minimum flow rates resulting from hygiene regulations or, if not, conventional specific flow rates defined in TH-C-E ex rules, plus the Crdb flow rate control coefficient equal to 1, and the overflow factors taking into account the uncertainties associated with the characterization of the mouths and leaks of the Cfres aerial network equal to 1.25 and Cd.
For premises for intermittently reunification of persons, as defined in annex III, the reference Crdnr flow reduction coefficient is 0.5.
The reference power of blowing fans and Pventref extraction fans is 0.30 watt per cubic metre and per hour of airflow per fan. This value is ranged to 0.45 for blowing fans if the installed system is equipped with a F5 to F9 Class Insufficient Filter. Powers are calculated for hygienic rates increased by 10%.
The reference consumption for a Joule effect heating system is calculated with the following data:
1. The system does not have losses for heating generation, storage and distribution;
2. The programming of the heating intermittences is provided by a programmator taking into account the internal temperature, directly or by a change of the control points of the terminal regulations, but not having an optimization function;

4. The losses on the back of the emitters are zero;
5. For category CE1, transmitters are not equipped with fans. For category CE2 premises, the transmitters are equipped with reference fans whose power is 2 W/m2.
For heating systems other than those referred to in Article 30, the reference consumption for heating is calculated with the following assumptions.

– a manual device allowing the extinction from each workstation.
Any local whose lighting control is within the purview of its management staff, even during periods of occupancy, must include a device for lighting and lighting ignition. If this device is not located in the local area, it will then have to allow to visualize the state of the lighting in this space from the place of order.
In premises with several uses requiring very different levels of illumination for at least two uses, such as sports premises and multi-purpose rooms, a device will have to reserve to persons authorized the start-up of higher lighting at the basic level.
In the same room, artificially illuminated points, which are placed less than 5 metres from a bay, must be ordered separately from other lighting points as soon as the total power installed in each of these positions is greater than 200 W.
When natural lighting is sufficient, artificial lighting should not be automatically started, including a clock or presence detection device.
In the case of non-residential buildings, cooled premises with a cooling system being installed or replaced as part of the work referred to in Article 4 shall be provided with specific ventilation devices.

― for residential buildings and accommodation cooled by refurbishment of new air without increasing the treated flows beyond the double of the hygiene requirements, the obligation of the first paragraph is considered satisfied if the supply of cold is, on the one hand, regulated at least according to the air recovery temperature and the outside temperature and, on the other, prohibited in heating period.
In the event of installation or replacement of the cooling system, the new system shall not heat and cool, or cool, and then heat the air, before final emission in the local area, with energy-using devices designed for heating or cooling air. This provision does not apply in case the heating is obtained by recovery on cold production.
For buildings for use in dwellings, equipped with a heating system or the production of collective sanitary hot water serving the dwellings in horizontal distribution, one or more devices shall allow to follow the consumption of heating and sanitary hot water, possibly confused, of each dwelling.
For non-residential buildings, if the heated surface exceeds 400 m2, one or more devices shall allow to monitor the operating time of each ventilation unit of the facility.

DEFINITION AND DETERMINATION OF EXHIBITIONS
OF BAIES IN THE BRUIT OF TRANSPORT INFRASTRUCTURES
The class of exposure of a bay to noise from an infrastructure depends on:
―from the classification of the ground transportation infrastructure in the vicinity of the construction, given by a prefectural order taken under the Decree No. 95-21 of 9 January 1995 relating to the classification of land transport infrastructure and amending the urban planning code and the code of construction and order dated 30 May 1996 relating to the classification of land transport infrastructure and the acoustic isolation of residential buildings in the areas affected by noise;
the situation of the bay in relation to these infrastructures;
―the situation of the building in relation to areas A, B, C or D of the noise exposure plan (PEB) of the airport approved by a prefectural order taken under articles R. 147-5 to R. 147-11 of the urban planning code,
in the following manner and conventions:
Definition of an obstacle to exposure
An obstacle to exposure is a mask to the spread of the noise (building, screen, earth butt...) having an altitude greater than or equal to that of the exposed floor.
When the obstacle is more than 250 metres from the bay under review and to take into account the curvature effect of the propagation of noise (nightly thermal reversal), 10 metres are added to the minimum altitude required to take into account the obstacle for residential premises.
Definition of an infrastructure view from a bay
The view of the infrastructure from a bay is defined as follows:
A direct view is defined for an infrastructure plan view of more than 30° after deduction of barriers to exposure. This is the case of side faces of a building without a mask.
A partial view is defined for a horizontal view of the infrastructure below 30°, after deduction of obstacles to exposure.
There is a masked view of the infrastructure when the infrastructure cannot be seen, taking into account obstacles to exposure, from the bay. When the obstacles to this view are of insufficient height within the meaning of the definition of an "hazard to exposure" to form a "shown view", but that they allow to remove any direct vision of the infrastructure, the view is then considered partial.
A rear view is defined for the rear façade of the building.
A protected rear view is defined for a bay located in a remote rear façade of the building and any vis-à-vis façade that would be directly exposed to the noise of the infrastructure.
A view of a closed courtyard can be reached for a closed courtyard on its four sides, without porch or open passage exposed to noise.
Determination of exposure class
at the sound of a bay of a building
1. Depending on the category of infrastructure near which the building or part of the building is built, and to the extent that this building is located at a distance greater than the maximum distance taken into account the transport infrastructure indicated below, all of its bays are then in the BR1 class of noise exposure.
| Infrastructure Category | 1 | Distance greater than 700 m. |
| of Land Transport: | 2 | Distance over 500 m. |
| | 3 | Distance greater than 250 m. |
| | 4 | Distance over 100 m. |
| | 5 | Distance greater than 30 m. |
| Aerodrome | | |
| Out of the noise exposure plan. |
| Category 1 | 15-50 m | 50-160 m | 160-300 m | 300-460 m | 460-700 m | 1,700 m |
| Category 2 | 0-25 m | 25-80 m | 80-250 m | 250-370 m | 370-500 m | 1 500 m |
| Category 3 | | 0-30 m | 30-100 m | 100-160 m | 160-250 m | 1 250 m |
| Category 4 | | 0-10 m | 10-30 m | 30-60 m | 60-100 m | 1 100 m |

2. Elements to be provided by the applicant
The request can be made either for a particular building project or for the inclusion of a particular system in several building projects.
2.1. Application for a specific building project
After indicating the calculation method that is not applicable, the applicant must provide:
- the design of the construction project concerned;
- the list of input data for parts of the calculation method that are applicable;
a detailed description of the reasons that make the calculation method unapplicable to other parties;
an explicit argument in which the project respects the principles at the basis of this regulation.
This argument must be used to justify the alleged level of performance of the operation, therefore the compliance with all the requirements of the regulations, both in respect of land guards, the limitation of summer discomfort and the limitation of conventional energy consumption.
2.2. Application for a particular system
usable in several building projects
After indicating the calculation method that is not applicable, the applicant must provide:
― a description of the system considered accompanied by elements to assess its thermal performance (test reports, measurement campaigns...) in particular with a view to justifying the adaptation proposal for the calculation;
a description of the scope of this system;
- the list of input data for parts of the calculation method that are applicable;
a detailed description of the reasons that make the calculation method unapplicable to other parties;
– an adaptation proposal to make the calculation for non-applicable parties. The proposed adaptation may relate either to the proposal of rules of entry by equivalence of input data of the TH-C-E ex calculation method, or to the proposal for processing of the output data of the calculation, together with an example of digital application.
In addition, the applicant may propose an adaptation of the algorithms of the TH-C-E ex calculation method.
