  A N N E X E
  PRICE MODALITIES IN ACCORDANCE WITH THE NILAN SYSTEM
  COMPACT IN THE THERMAL REGULATION 2005
  1. Definition of Nilan Compact P system

  
  For the purpose of this decree, the Nilan Compact P system is a double-flow thermodynamic ventilation system. The system ensures ventilation, part of the heating, production of sanitary hot water and, if applicable, refreshment:
  ―new air renewal (with filtration);
  ― static recovery on air extracted from a thermodynamic recovery (heat pump on air extract);
  ― refreshing the air provided in summer by the thermodynamic system (reversible system) completed with a static exchanger and bypass;
  ― production of sanitary hot water using the thermodynamic system. In the summer, the heat pump condenser promotes the production of sanitary hot water.

  
  2. Area of application

  
  This method applies only to residential buildings (individual house and collective building) with a living area, by dwelling, between 70 m2 and 240 m2 and heated:
  - electricity;
  - in the oil, gas or wood by boilers whose combustion products are evacuated independently of the ventilation system.

  
  3. Method of inclusion in calculations
  for the non-directly flexible part

  
  This method proposes the integration of the Nilan Compact P system into the Th-C-E calculation method, as consisting of three separate systems:
  – a dual flow mechanical ventilation with a heat exchanger;
  – a heating booster system, possibly refreshing, thermodynamic on outdoor air;
  ―a system of thermodynamic hot water production on outdoor air.
  This method assumes that the heating and hot water production modes are separated.

  
  3.1. Modelling of the ventilation system

  
  The value of the nominal output of the dual flow ventilation system is by linear interpolation between two columns of Table 1 following depending on the reference air flow:

  
  Table 1: Nominal exchanger yield value

  
  

  Base air flow rate (m3/h)	128,6	191.9	289.6
  Exchanger yield (percentage)	90	88	85

  
  
  The yield value is considered certified as defined in the Th-C-E calculation method. The calculation value is equal to the certified value.
  The three binomes (reference air flow)/(return of the exchanger) to determine the nominal return of the exchanger are:
  ―from Table 1;
  - be determined from values certified by an independent body accredited under the NF EN 45011 standard by COFRAC or any other accreditation body that is a signatory to the relevant European multilateral agreement as part of the European coordination of accreditation bodies, based on the NF EN 308 standard; the three airflows to which the tests have been carried out shall then take the values between 80 and 100 m3/h, 100 and 200 m3/h, 200 and 300 m3/h respectively.
  The calculation of fan power is as follows:

  
  Pvent = 0.337 × Dair

  
  with:
  Dair: reference airflow.

  
  3.2. Modelling of the heating system

  
  The heating generation system is modelled as follows:
  – a heat pump (external air/recycled air) without loss of distribution and with management according to the internal temperature;
  – regulation in all or nothing.
  The heating emission system is modelled as follows:
  - emitters with a Class B spatial variation and a temporal variation with the default values (regulations that do not allow a total emission stopping);
  – a programming corresponding to a fixed time clock with mood control.
  The basic system + supplement of Annex B of the Th-C-E rules is used.
  The values of COP and power of the heating system are obtained by linear interpolation between two columns of Table 2 following according to the reference air flow:

  
  Table 2: COP and heating system power values

  
  
  

  
  
  7/20 °C
  7/20 °C

  Reference airflow (m3/h)	92	179	235	92	179	235
  COP	2.69	3,32	3.55	2,39	2.79	2.88
  Power (kW)	P = 2/3 * 0.86	P = 2/3 * 1.03	P = 2/3 * 1.1	P = 2/3 * 0.55	P = 2/3 * 0.67	P = 2/3 * 0.72

  
  
  COP values are considered to be reported within the meaning of the Th-C-E calculation method. The calculation value is 0.8* declared value.
  The six trinômes (reference air flow rate)/(COP)/(Puissance) to determine the values of COP and heating system power are:
  ―from Table 2;
  - be determined from measured values on the basis of NF EN 14511; the three airflows to which the tests have been carried out shall then take the values between 80 and 100 m3/h, 100 and 200 m3/h, 200 and 300 m3/h respectively and, for the values taken in each interval, be identical to ― 7/20 °C and 7/20 °C.

  
  3.3. Modelling of the cooling system

  
  The cooling generation system is modelled as follows:
  – a heat pump (external air/recycled air) without loss of distribution and with management according to the internal temperature;
  – regulation everything or nothing.
  The cooling emission system is modelled as follows:
  - emitters with a Class C spatial variation and a temporal variation with the default values (regulations that do not allow a total emission stopping);
  – a programming corresponding to a fixed time clock with mood control.
  The EER and power values of the cooling system are obtained by linear interpolation between two columns of Table 3 following depending on the reference air flow:

  
  Table 3: COP and cooling system power values

  
  

  
  
  35/25 °C

  Reference airflow (m3/h)	92	179	235
  EER	0.95	1.74	2,06
  Power (kW)	0.56	0.87	0.99

  
  
  EER values are considered declared within the meaning of the Th-C-E calculation method. The calculation value is 0.8* declared value.
  The three trinômes (reference air flow rate)/(EER)/(Puissance) to determine the EER and cooling system power values are:
  ―from Table 3;
  - be determined from measured values on the basis of NF EN 14511; the three airflows to which the tests have been carried out shall then take the values between 80 and 100 m3/h, 100 and 200 m3/h, 200 and 300 m3/h respectively.

  
  3.4. Modelling of the ECS production system

  
  The ECS generation system is modeled through the aforementioned 13 May 2011 decision taking into account an external air system. The COP values at + 7° C of the thermodynamic ECS production system are determined in accordance with the NF EN 16147 standard, for a reference temperature, WH ≥ 52.5 °C and obtained by linear interpolation between two columns of table 4 following according to the reference air flow:

  
  Table 4: COP values of the thermodynamic ECS system

  
  

  
  
  7 °C

  Reference airflow (m3/h)	100	200	280
  COP	2,14	2.25	2,30

  
  
  The COP values of the thermodynamic ECS production system are considered by a test conducted by an independent laboratory and accredited according to the NF EN ISO/CEI 17025 by COFRAC or any other accreditation body signatory to the relevant European multilateral agreement as part of the European coordination of accreditation bodies. The calculation value is 0.9* justified.
  The three binomes (reference air flow)/(COP) to determine COP values of the sanitary hot water production system are:
  ―from Table 4;
  - be determined from values justified by a test conducted by an independent laboratory and accredited according to the NF EN ISO/CEI 17025 standard by COFRAC or any other accreditation body signatory to the relevant European multilateral agreement as part of the European coordination of accreditation bodies based on the NF EN 16147 standard; the three airflows to which the tests have been carried out shall then take the values between 80 and 100 m3/h, 100 and 200 m3/h, 200 and 300 m3/h respectively.
  The value of the electric power of the thermodynamic ECS system to compensate for storage losses, Pes, is:
  equal to 35.1 W;
  - be determined from a value justified by a test conducted by an independent laboratory and accredited according to the NF EN ISO/CEI 17025 standard by COFRAC or any other accreditation body signatory to the relevant European multilateral agreement as part of the European coordination of accreditation bodies.
  The Pes value is considered justified within the meaning of the Th-C-E calculation method. The calculation value is 1.1* justified.
