Energy savings certificates Calculation sheet Installation of complete windows or French windows* A- APPLICATION SECTOR Residential building: existing individual houses and apartments B- DESCRIPTION OF STANDARD OPERATION Installation of a complete window or French window with air vents (if necessary) corresponding to a surface transmission coefficient Uw of 2 W/m²K. Installation of a complete window or French window with air vents (if necessary) corresponding to a surface transmission coefficient Uw between 2 and 2.5 W/m²K. Special conditions for granting of certificates Windows and French windows will have NF CSTBat certification and an ACOTHERM label or equivalent. Windows and French windows must comply with CE marking as soon as this is applicable. Where there is no certification, the systems used to manufacture the windows or French windows must be accredited or have been the subject of a Technical Evaluation. Windows and French windows must be double-glazed with increased insulation certified by CEKAL. Windows and French windows must be installed in accordance with the DTU and directions set out in the CSTB specifications in effect for each type of material (aluminium, wood and PVC). Installation carried out by a professional. * Complete replacement means the installation of a complete window (frame + casement). The old window frame may be retained and used as an external frame installed in accordance with the CTSB specification.

D- BASELINE SITUATION Correction for climatic area (cf. RT 2000) Area Climatic coefficient H1 1.1 H2 0.9 H3 0.6 The aim of these works will be to replace old windows and French windows with poorly performing single or double-glazing. The average surface transmission coefficient Uw in each of these cases is: Old frames fitted with Single Glazing => Uw = 5 W/(m².K) Standard wooden frames fitted with 4/6/4 clear Double Glazing => Uw = 4W/(m².K) In order to simplify the process, and given the difficulty of verifying the initial position after the event, a single value has been used to value window and French window replacement activities, whatever the initial position. The baseline surface transmission coefficient for this activity is Uw = 4.5 W/m²K. This value is a penalising factor in view of the proportion of individual houses built before 1975 not covered by any regulations (62%) and the proportion of domestic households replacing single-glazed windows compared with all those replacing windows (95%; source: ADEME). E- NATURE OF OPERATION AND LIMITS OF VALUATION Installing windows or French windows with a surface transmission coefficient Uw of less than 2W/m²K is valued at 100%. However, so as to retain an incentive to move towards better performance, installing windows or French windows with a surface transmission coefficient Uw between 2.5 and 2 W/m²K has been valued at 50%.

The old window frame may be retained and used as an external frame installed in accordance with the CTSB specifications. The rules for installing windows in existing frames are set out in the CSTB technical specifications. There are no restrictions on the thermal performance of this technique compared with installation into masonry. Windows installed according to the so-called renovation technique can be ACOTHERM certified in the same way as newly installed windows. BR81 - Page 4/4

Energy savings certificates Calculation sheet Water/water type heat pump A- APPLICATION SECTOR Residential building: existing individual houses and apartments. B- DESCRIPTION OF STANDARD OPERATION Installation of a water/water type heat pump. Special conditions for granting of certificates Performance coefficient measured in accordance with standard EN 14511 equal to or greater than 3. Installation carried out by a professional Remarks: The only eligible systems are heat pumps, i.e. appliances designed to produce heat (primarily through their heat exchangers) and which may or may not produce cool air if reversible. The domestic hot water that may be produced by the heat pump from a renewable energy source is not considered here. This may be reviewed as the potential of heat pumps changes over time. In the absence of any particular requirement for the value of the performance coefficient being clearly defined in the programme, a value of 3 will be used as a baseline. ---------------Groupe de travail----------------- Documents de référence Bâtiment résidentiel : équipement Bâtiment résidentiel : enveloppe et systèmes thermiques fixes Bâtiment tertiaire : équipement N Rev date Bâtiment tertiaire : enveloppe et systèmes thermiques fixes Collectivités locales et réseaux de chaleur Industrie Services d'efficacité énergétique Transport Fiche de calcul Correspondants Fiche de synthèse associée validation ATEE BR112 7 06/03/2006 27/09/2005 16/01/2006 validation ADEME ATEE ADEME N Date N DIDEME D.

Total market (new and existing) 1,317,000 dwellings Taking into account the construction of 340,000 homes every year, the existing market is estimated at 980,000 dwellings. The vast majority of heat pumps are currently installed in new homes (95%). The existing market for air/water pumps is of the order of a few hundred units. It appears to be larger in the air/air sector (as a replacement for electric heating). Although this is low, a symbolic coefficient of 0.995 has been applied to take account of the current market in existing homes. This coefficient equates to around 5,000 appliances installed in existing homes, which is much higher than in reality. F- AMOUNT OF ENERGY GAIN GENERATED PER STANDARD OPERATION (expressed in kwh/year and per home treated) As heat pumps use renewable energy sources, the calculation has been based on taking into consideration the production of heat from a renewable source (from the ground in this example).

17,000 multi-split air/air heat pumps of 7 to 17 kw per year Total market (new and existing) 1,317,000 dwellings Taking into account the construction of 340,000 homes every year, the existing market is estimated at 980,000 dwellings. The vast majority of heat pumps, all technologies combined, is currently installed in new homes (95%). In renovation projects, air/air heat pumps are usually installed to provide additional heating in one or more rooms. The aim of this standard operation is to provide 95% of heating throughout the period when heating is required. Although this is low, a coefficient of 0.95 has been applied to take account of the current market in existing homes. F- AMOUNT OF ENERGY GAIN GENERATED PER STANDARD OPERATION (expressed in kwh/year and per home treated) As heat pumps use renewable energy sources, the calculation has been based on taking into consideration the production of heat from a renewable source (from the air in this example). Hypotheses: Appliance performance coefficient = 3.2 or 3.6 (the performance coefficient is measured in accordance with standard EN 14511 and certified by Eurovent Certification). 95% of heating requirements are covered by the heat pump. Unit: kwh/year and per average-sized dwelling (equivalent to the average number of main rooms shown in table 2).

Average consumption (CEREN statistics given in methodology note) Calculation principle: Distribution and production yield of equivalent systems in current building stock APPENDIX Calculation hypotheses The ESC values solely the quantity of renewable energy taken from the environment. This therefore refers to the quantity Q1 in the preceding diagram. The value Q1 is obtained from the performance coefficient and quantity of energy produced as an output from the heat pump (Q2) to satisfy the heating requirement. COP Heating requirem ent to be satisfied Heat pump distribution yield Quantity of heat produced as an output from the heat pump = Q2 Q2 and Q2 Q1 W Q1 Q2 1 1 W COP The quantity Q2 is initially calculated based on the heating requirement to be satisfied, taking into account the distribution yield hypotheses for the heat pump. The heating requirement to be satisfied is established on the basis of average consumption statistics and average yield hypotheses for the equipment installed. As these systems can be reversible, a summer consumption of 0.5kWh/m² has been deducted from the energy gains. Yield hypotheses: The following yields have been used to convert consumption statistics into a heating requirement and then into the quantity of heat to be produced by the heat pump condenser: Production yield for electric heating: 1 Distribution yield for electric heating: 0.98 Production yield for an individual fuel-based boiler (current installed base): 0.8 Distribution yield for the network of radiators connected to the fuel-based boiler: 0.85 Distribution yield for air/air heat pump: 0.95 Breakdown of housing stock (in thousands) by heating energy (CEREN 2000): Before 1975 After 1975 Totals Apartment: electric 1,372 1,276 2,648 Apartment: heating oil or other 1,950 475 2,425 Apartment: gas (or LPG) shared 1,951 353 2,304 Apartment: gas (or LPG) individual 1,792 735 2,527 Total number of apartments 7,065 2,839 9,904 IH: electric 1,198 2,303 3,501 IH: heating oil or other 4,391 1,598 5,989 IH: gas (or LPG) 2,766 1,157 3,923 Total number of IH 8,355 5,058 13,413 Totals 15,420 7,897 23,317 Quantity of heat from renewable sources taken from the environment = Q1 Electrical energy consumed by the compressor + non-permanent auxiliary sources = W BR121 Air/air heat pump Page 5/5

The gain is calculated over the life span of the CFL (6,000 hours) with an average annual use of 800 hours (i.e. 2 hours 10 minutes per day), to give a programme length of 7.5 years. Today, 70% of the 8 million CFLs sold annually are used as a substitute for an incandescent light source (75 W) whilst 30% are used to replace a CFL (18 W) that has reached the end of its life (source: SOFRES 2001). An 18 W CFL equates to a theoretical 80 W incandescent bulb. Potential yield from the operation: 80% of the annual sales of 8 million CFLs are made through mass-market retailers. We have calculated that the potential yield is therefore: 0.8 x 8,000,000 = 6,400,000 CFL/year i.e. 6,400,000 x 230 = 1.472 TWh/year Average price of an incandescent bulb 0.80 Average price of a CFL 5 Additional cost: 4.20 Gain (cumac) per CFL 230 kwh Value of ESCs at 0.01/kWh 2.30 ESC coverage of additional cost 55% 1 Other bulbs include fluorescent tubes, low-voltage and pencil-style halogen bulbs, etc. BR20 - Page 3/3

APPENDIX Additional information Annual consumption of installed base of domestic refrigeration equipment: 15.4 TWh in 2001 (Data: CEREN) Market data The installed base of refrigeration equipment is 39 million appliances (4 million of which are doubled up). Annual sales total 3 million appliances (source: GIFAM), 75% of which are to replace existing stock (SOFRES 1999). The baseline calculation for domestic refrigeration appliances is based on the range of products available in stores (information gathered from websites and catalogues), distinguishing between combined fridge-freezers, refrigerators and freezers. Information about upright and chest freezers is combined in the calculation of unit gains in order to avoid increasing the number of types of appliance.

Aluminium frames are predominant in non-residential building renovations, with a market share estimated at over 55%, followed by PVC with 30% and wood at just over 10%. Given the predominance of aluminium frames in the renovations market for non-residential buildings and the absence of any regulatory requirements for renovation works, the performance of windows installed in this sector is currently significantly in excess of 3W/(m².K), although this figure should decrease with RT2005. The exemplary renovation works carried out on certain buildings, such as junior and senior secondary schools, under the influence of the HEQ scheme, are still very much in the minority. The aim of these works will be to replace old windows and French windows with poorly performing single or double glazing. The average surface transmission coefficient Uw in each of these cases is: Old aluminium frames fitted with Single Glazing => Uw = 6.15 W/(m².K) Aluminium frames with 4/6/4 clear Double Glazing => Uw = 4.5W/(m².K) BT232 Replacement of windows and French windows Page 2/5

The share of aluminium frames in the building stock to be renovated is of the order of 85%. Based on the minimum hypothesis that 1/3 of the old buildings to be renovated have single glazing in aluminium frames, the average Uw coefficient would be 5 W/(m².K). In order to simplify the process, and given the difficulty of verifying the initial position after the event, a single value has been used to value window and French window replacement activities, whatever the initial position. The baseline surface transmission coefficient for this activity is Uw = 5 W/m²K.

E- BASELINE SITUATION Depending on the technical constraints of the project (evacuation of by-products of combustion, size of heat exchangers, etc.) it is not always possible to install the best available technology, i.e. a condensing boiler, as a replacement for an obsolete boiler or as a new installation in an existing building. In order to take account of the technical and economic realities in which projects are carried out, the installation of a low-temperature boiler that offers a significant gain in energy performance is valued in terms of energy savings certificates. So as to retain an incentive to move towards better performance, however, the standard gain of 35% obtained compared with a typical boiler from the old installed base is only valued at 50%, i.e. 17.5%.

The load factor is calculated by taking the time of use multiplied by the average motor load. This load factor is taken from the European study Improving the Penetration of Energy Efficient Motors and Drives carried out as part of the SAVE II 2000 programme. This study is based on analysis of six industrial sectors representing 75% of the total consumption of motors in the European Union. This load factor assessment only includes sectors not subject to the National Allocation Plan (NAP).

APPENDIX Additional information Operation context: - Improvement of existing system or replacement of a motor for final use - One-off purchase of an EFF1 energy efficient motor - Purchase of equipment fitted with EFF1 energy efficient motors How has the standard energy saving been estimated for the operation concerned? - Baseline: CEMEP classification of squirrel-cage motors (1.1 kw - 90 kw, 3000 rpm or 1500 rpm) - Baseline situation: motor corresponding to the motor market average in 2003 (CEMEP data) - Assessment of average motor efficiency for each of the efficiency classes 2 calculation sources: o Source 1: Estimated average efficiency per power class of motors available in France, produced by the two main manufacturers in the market: EFF2 class motor: the efficiency is assumed equal to the average observed for motors available on the French market (according to technical data provided by the two main suppliers) distinguishing between 2-pole 3000 rpm motors and 4-pole 1500 rpm motors. EFF1 class motor: the efficiency is assumed equal to the average observed for motors available on the French market (according to technical data provided by the two main suppliers) distinguishing between 2-pole 3000 rpm motors and 4-pole 1500 rpm motors). EFF3 class motor: the efficiency is assumed equal to the average observed for motors available on the French market according to data obtained from the EuroDEEM 2000 database, averaged between 2-pole 3000 rpm motors and 4-pole 1500 rpm motors. o Source 2: Efficiency limits for the different classes defined for the EFF1, EFF2 and EFF3 categories. In order to limit the potential effects arising from samples that are small and therefore distorted by the range of choices made by the motor manufacturers, the difference between the two sources is calculated for each motor power range, then averaged to give a single constant value for the entire power table, for each category. The efficiency values considered are shown in the table below (CEMEP limits and values used for typical cases). I500 - Page 6/10

E- BASELINE SITUATION The operation applies to all new or existing installations including motors (pumps, fans and compressors) with variable loads, regulated by a device giving rise to losses (bypass, throttling, etc.). The conventional system is replaced by an electronic variable speed drive, which is the most energy-efficient solution. IMPORTANT: Note that energy gains from individual operations can be highly variable. Before any installation, a specific analysis must systematically be performed to determine its technical and economic feasibility. Market condition and technical potential VSDs for electric Motor Systems, produced as part of the European SAVE II project: Basic data used to assess potential gains in the industrial sector: Application Application possibility (%) Existing application (%) Technical potential (%) Pumps 60 9 51 fans 60 7 53 Compressed air 30 5 25 Incorporating the market baseline situation: Compressed air Ventilation Pumping 0.69% 3.86% 3.64% F- AMOUNT OF ENERGY SAVING GENERATED PER STANDARD OPERATION (expressed in kwh per year) There is no simple segmentation method for calculating the saving associated with the I502 - Page 2/7

installation of variable speed drive systems. The key parameters involved characterize variation ranges (flow levels and associated times). These parameters are highly variable: they depend on the installation design calculations, the process type, production organisation, etc. The simplest fixed rate approach therefore consists of establishing the following savings: Pumps and fans: 30% saving, Compressors: 15% saving. Energy saving taking the market structure into consideration: Application Average saving (%) Pumps 28.9 Fans 28.8 Compressed air 14.9 The number of operating hours can also be set at a fixed rate: Application Annual duration (hours) Pumping 5,091 Ventilation 6,148 Compressed air 4,709 Energy saving in kwh/year according to the application and motor rating: Energy saving per year Application and per kw of motor rating Pumping 1,472 Ventilation 1,773 Compressed air 701 NB: This assessment of the saving corresponds to the average of the cases considered. Under no circumstances may it be used to prove energy savings on a project to the customer the customer. It will be used solely for administrative purposes for MDE programme directives. In all cases, the detailed calculation of the saving must be performed as part of the preinstallation study carried out for the customer company, taking the economic and technical parameters into consideration.

APPENDIX Additional information Operation context: Improvement of existing installations for pumps and fans or renewal in the case of air compressors Isolated or combined operation How has the standard energy saving been estimated for the operation concerned? Baseline situation: motor equipped with a load variation device giving rise to losses. Description of the new situation: replacement of the existing load variation device by a VSD The estimated fixed savings of 30% and 15% are based on in situ feedback. The number of operating hours has been set as follows: - for industry: source - SAVE study Improving the penetration of energy-efficient motors and drives see table 1 below, Estimated life span: 10 years.
