RT 2000) Area Climatic coefficient H1 1.1 H2 0.9 H3 0.6 The average Upinit coefficient used for external walls is 3.3 W/m².K. E- NATURE OF OPERATION AND LIMITS OF VALUATION Depending on the technical constraints of the project, it is not always possible to install insulation with thermal resistance equal to or greater than 2.4 m²k/w. In order to take account of these difficulties, installing insulation with thermal resistance of between 1.2 and 2.4 m²k/w has been valued at 50%. However, so as to retain an incentive to move towards better performance, installing insulation greater than or equal to 2.4 m²k/w has been valued at 100%.

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.

9 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%.

11 APPENDIX Additional information Baseline hypotheses: - Uninsulated roof/loft: Transmission coefficient Up = 3 W/(m².K) - Poorly insulated roof/loft: Transmission coefficient Up = 1 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 insulation activities, whatever the initial position. The baseline transmission coefficient for this activity is Upinit = 2 W/m²K Average degree day (ADD): 2,450 K Intermittency coefficient and incidental gain = 0.5 Yield from electric heating system: = 95% Yield from fuel-based heating system: = 60% Up final = 1/(1/Up initial +R) Up = Up final Upinit Gain = Up x average ADD x 24h x 0.5 / Number of individual houses = 13,537,577 (source: 1999 census) Of which built pre-1975 = 8,383,482 (62%) Number of domestic households having carried out insulation work in uninsulated lofts and roofs in 2002 = 223,500 (source: ADEME) Number of domestic households having carried out insulation work in poorly insulated lofts and roofs in 2002 = 76,800 (source: ADEME) 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 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

14 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 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). Hypotheses: Appliance performance coefficient = 3 or 3.5 or 4 (the performance coefficient is that indicated by the manufacturer and measured in accordance with standard EN 14511). 100% of heating requirements 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).

33 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 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).

35 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, ,425 Apartment: gas (or LPG) shared 1, ,304 Apartment: gas (or LPG) individual 1, ,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 = 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

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

54 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.

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.

84 C- PERFORMANCE DIFFERENTIATION CRITERIA FOR STANDARD OPERATION ACCORDING TO INSTALLATION CONDITIONS Criterion 1: Type of motor use: pump, fan, compressor Criterion 2: Power rating of motor D- AVERAGE CONSUMPTION STATISTICS According to the 1999 CEREN study on potential resources for energy management in industry: Electric motors represent on average 70% of electrical energy consumption in industry, or 89 TWh in 1997 Pumps, fans and compressors represent 43.5 TWh All industrial sectors combined, pumps, fans and compressors operating in load fluctuation represent 16.4 TWh, including 1.4 TWh corresponding to machines already equipped with variable speed drives (mechanical or electronic). 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 fans Compressed air 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

85 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.
