25 LODGE S DESCRIPTION Briefing indicating operation regime, schedule, capacity, occupation, activities performed. This lodge is suitable for the accommodation of 42 old people. Due to the fact that a senior home guest permanent lodger, the establishment works 24h per day during all the year. The annual occupancy rate is 95 %. In the lodge, we can find a collective kitchen linked to a restaurant. There is no laundry in the building. Brief description about constructive characteristics. The building can be divided in two parts : o the castle : o the annex : The old part of the lodge, build with stones. The density of nearby obstructions can be describe as moderately dense. The part has been totally modernize in This part was build in 1990 mainly with stones and is now linked to the castle. All the windows are double-pane glass and the roof is well insulated. Walls of the castle are not insulated but it s impossible to realize a external insulation. An internal insulation present lots of risk for the building structure and is quite expensive. Short description about systems and appliances that consume energy (heating, cooling, lighting systems, domestic hot water production, kitchen equipments, etc.) A fuel boiler of 479 kw provide the building with heat and domestic hot water. The burner can be drive at two different speeds; commanded by aquastats. Three climatic regulations adapt the temperature of different circuits for heat distribution. Lighting systems mainly use fluorescent tubes. No cooling system is required and installed. ICEDD asbl Page 25 of 52

Short description about systems and appliances that consume energy (heating, cooling, lighting systems, domestic hot water production, kitchen equipments, etc.) There are two fuel boilers of 183 kw each to heat the building. Burners are double-speed burner. Domestic hot water is produce by another boiler of 43 kw linked to a hot water tank of 400 litres. A climatic regulation is installed in the electric panel; heating terminal units are provided with thermostats. Lighting systems mainly use incandescent lamps. No cooling system is required and installed. ENERGY DEMAND Characterisation of energy supplies, principally fares structure. ICEDD asbl Page 48 of 52
