3 Design Criteria The design criteria will be in accordance with the recommendations of the following: Back of house circulation 13 to 20°C ± 2°C 21 to 25°C ± 2°C 10 l/s/person • This RIBA stage 2 report • CIBSE Guides • Statutory undertakings • Health and Safety Executive (HSE) Guidance and all relevant legislation • CDM regulations • Pressure system safety regulations • Relevant British Standards External design conditions External design conditions for thermal load calculations and plant sizing will in general have been determined in accordance with CIBSE Guide, Section A2, Weather and Solar Data and the design criteria identified by and discussed with the users. Winter: -5°C Summer: 30°C db, 21°C wb Chillers: 35°C Summer & -10°C Internal Design Conditions Location Winter Summer Ventilation Requirements Exhibition space / event space 19 to 21°C ± 2°C 21 to 25°C ± 2°C 10 l/s/person Hogarth gallery 19 to 21°C ± 2°C 21 to 25°C ± 2°C 10 l/s/person – Humidity control required to this space and any adjacent connected galleries. Café 19 to 21°C ± 2°C 21 to 25°C ± 2°C 10 l/s/person Main kitchen 17 to 19°C ± 2°C 21 to 25°C ± 2°C 40 ACH Choir Room 19 to 21°C ± 2°C 21 to 25°C ± 2°C 10 l/s/person Comms room 19 to 21°C ± 2°C 12 to 25°C ± 2°C 10 l/s/person Plant rooms Uncontrolled with Frost Protection Uncontrolled Occupation density Occupation densities are generally based on furniture layouts shown on architectural layouts. To achieve the design criteria with natural ventilation servicing strategies, limits will be defined for the occupancy at the next stage of design. Noise Criteria Gallery Spaces NR30-35 Café NR40-45 Events Space NR40-45 Circulation Spaces NR45 Plantrooms NR75 Site Boundary Noise levels to be confirmed by Environmental Health Officer or acoustic consultant. Design Internal Heat Gains People Sensible – 90W per person Latent – 50W per person Lighting 8 W/m² Equipment Schedules to be provided by the users Infiltration Rate The external air infiltration rate will be taken as 0.5 air change per hour in winter and 0.5 air changes per hour in summer. This is the air infiltration to be utilised in heat loss/ heat gain calculations and will account for both occupied spaces and the ceiling/ floor voids. As the design progresses, the specified airtightness of the building will be applied to improve the accuracy of the heat gain and heat loss calculations. Drainage The above ground drainage and sanitation systems will be designed generally to comply with the following standards and regulations: BS8301 Building Drainage BS 5572 Sanitary Pipework CP 305 Sanitary Appliances Building Regulation and Water Regulations Office 21 to 23°C ± 1°C 22 to 25°C ± 2°C 10 l/s/person Toilets 19 to 21°C ± 1°C 21 to 25°C ± 1°C >5 ACH 1563.R1 – Stage 2 report Page 6 of 29

EXISTING ELECTRICAL AND MAINS COLD WATER CAPACITY TO BE ASSESSED AND PLANT ROOM REQUIREMENTS ADVISED ACCORDINGLY. LOW LEVEL KITCHEN EXHAUST PROPOSED - AS CURRENTLY INSTALLED ELECTRICAL DISTRIBUTION BOARD MEP STRATEGY DRAWINGS The following drawings highlight the intended MEP strategic approach. In accordance with the outcomes of RIBA 2, they provide a robust basis for further development at RIBA 3 This is particularly critical, as a key element of the design approach is the requirement for: ROUTE REQUIRED FOR KITCHEN EXHAUST DUCTWORK EXISTING BOILER PLANT TO REMAIN. NEW AREAS HEATED BY AIR SOURCE HEAT PUMP. • Natural and passive environmental strategies wherever possible • A ‘fabric-first’ approach to sustainability • The maximum concealment of services to maintain the purity of the spaces themselves PROJECT: ST MARY REDCLIFFE SKETCH TITLE: BASEMENT M&E COMMENTS_rev 4 DATE: 29/08/2019 ENGR: JD
