Each apartment will be provided with whole house heat recovery ventilation (MVHR) to extract air from the kitchen, bathroom(s) and utility room and to provide fresh air to the living areas and bedrooms. Ventilation extract boost will be operated by a switch located in the kitchen. The MVHR will also incorporate summer bypass. Extract grilles shall come with integrated removable filters to comply with the latest NHBC standards. All ductwork will be rigid plastic ductwork. There will be no use of flexible ductwork. Intake and exhaust ductwork will be insulated to prevent condensation. A double air brick on the façade shall be required for connecting the MVHR ventilation ductwork intake and discharge points to outside. Purge ventilation to each room will be provided through the use of an openable window. Cookers will be provided with recirculation hoods, as specified by the Architect. 2.2 Community Facility [D1] The Community Facility shall be provided with mechanical supply and extract ventilation based on 10l/s/person and in compliance with Building Regulations Part F. Ventilation shall be supplied from two central air handling units (AHU) as follows: Library AHU This AHU is located at high level in Block 2 cycle store (making use of the high floor to under soffit dimensions). The AHU will comprise of filters, heating and cooling coils and a thermal wheel. Air intake and exhaust shall be via high level louvres on the façade at ground floor level (see Figure 2). Stay & Play and Community Trust AHU This AHU is located at high level within the Buggy Store ceiling void. The AHU will comprise of filters, heating and cooling coils and a plate heat exchanger. Air intake and exhaust shall be via high level louvres on the façade at ground floor level (see Figure 2). Refer to Appendix A for detailed ventilation drawing of the North block ground floor. Figure 2: Community Facility ventilation strategy Intake 44444 AHU AHU Stay & Play Community Facility Creation Trust 2

2.3 Commercial unit [A1] The commercial unit is being designed as a shell and core for fit out by tenant. As part of the shell and core provision, high level louvres will be provided at ground floor level on each façade for the ventilation units to discharge exhaust air and bring in fresh air (see Figure 3). Final ventilation shall be designed and provided by the Fit-out contractor to suit the use of the space. Refer to Appendix A for detailed ventilation drawing of the North block ground floor. 2.4 Cafe [A1 / A3 ] The cafe is being designed as a shell and core for fit out by tennant. As part of the shell and core provision, high level louvres will be provided at ground floor at the front façade for the ventilation units to discharge exhaust air and bring in fresh air (see Figure 3). Final ventilation shall be designed and provided by the Fit-out contractor to suit the use of the space. Refer to Appendix A for detailed ventilation drawing of the North block ground floor.

3 South Block Ventilation 3.1 Health Centre [D1] The Health Centre shall be provided with mechanical supply and extract ventilation in accordance with Health Technical Memorandum (HTM) 03-01. Ventilation shall be supplied from a central air handling units (AHU) at roof level. The AHU will comprise of filters, heating and cooling coils and a thermal wheel. Air intake and exhaust shall be at roof level and separated by a distance of circa 10m and on different facades of the roof plant enclosure. Two smoke extract fans will also provide smoke clearance to the stair lobbies at each floor (see Figure 4). Refer also to Appendix B for a detailed roof level drawing of the South Block. 3.2 Early Years [D1] The Earl Years nursery shall be provided with mechanical ventilation in accordance with Part F of Building Regu lations. Ventilation shall be supplied from two central air handling units Early Years Facility and General AHU This AHU is located at roof level and will comprise of filters, heating and cooling coils and a plate heat exchanger. Air intake and exhaust shall also be at roof level and separated by a distance of circa 10m and on different facades of the roof plant enclosure (see Figure 4). Early Years Facility Kitchen AHU and extract fan The kitchen extract system shall meet the standard required by DEFRA Guidance on 'The control of odour and noise from commercial kitchen exhaust systems' (2011). A kitchen extract fan shall be provided at roof level with the exhaust also at roof level. Make-up supply air will be provided by a dedicated supply only AHU at roof levelthe AHU will comprise of filters and heating coils. The air intake will be at roof level and separated from the exhaust by a distance of circa 10m and on different facades of the roof plant enclosure (see Figure 4). Refer also to Appendix B for a detailed roof level drawing of the South Block.

3.3 South Block Basement BOH [D1] The Basement Back of House (BOH) areas shall be provided with mechanical ventilation in accordance with Part F of Building Regulations. Supply air ventilation shall be supplied from a roof mounted AHU and will comprise of filters, heating coils and a run-around heat recover coil linked to the extract unit located in the basement. Air intake is at roof level and is ducted through the building to the basement level to supply fresh air (see figure 4 above). The BOH areas of the basement shall have air extracted via an extract fan at basement level. The extracted air will be exhausted to outside at ground floor via louvres integrated into landscape feature (see Figure 5). This system will also run to provide smoke extract (albeit with dedicated smoke extract fans) in line with the Fire strategy. 3.4 South Block Basement Car Park [D1] The basement car park will be mechanically ventilated in accordance with Building Regulations Approved Document Part F and Part B and will achieve the standards set out in BS 7346-7: 2013. Dedicated duty / standby car park extract fans will extract air from one end of the car park and exhausting the air to outside at ground floor. In normal mode it will extract 6 ac/hr. In fire mode it will extract 10ac/hr. Make-up air will be drawn in naturally via the car park ramp entrance. In order to achieve good distribution of air flow, the mechanical ventilation will be supported with an impulse fan (see Figure 5). Refer also to Appendix C for a detailed basement drawing of the South Block ventilation.

4 Other Plant Flues and s 4.1 Temporary gas fire boilers A purpose-built flue riser will accommodate the temporary boiler flues in the North Block heating plantroom. An individual flue will be provided for each boiler, running horizontally to the flue riser in Block 1 and will then rise vertically to discharge to atmosphere at the highest point of level 15 roof level to comply with the requirements of the Clean Air Act (see Figure 6) The condensing boilers shall be low NOx type achieving 35mg/kWh NOx emissions. Refer also to Appendix D for a detailed drawing of the North block roof with MEP services. 4.2 North Block Life safety generator A life safety generator will be provided for back up electricity on failure of mains electricity to life safety systems in the North Block. The generator will be located at roof level with the flue discharging above the generator to meet the Clean Air Acts requirement (see Figure 6). As the generator is proposed for emergency only, it will only be running during scheduled tests or in the event of a power cut. Refer also to Appendix D for a detailed drawing of the North block roof with MEP services. 4.3 South Block Life safety generator A life safety generator will be provided for back up electricity on failure of mains electricity to life safety systems in the South Block. The generator will be located at roof level with the flue discharging above the generator to meet the Clean Air Acts requirement (see Figure 4 on page 4). As the generator is proposed for emergency only, it will only be running during scheduled tests or in the event of a power cut. Refer also to Appendix B for a detailed roof level drawing of the South Block.
