  • 1.6     Lighting Heat Gain
    The design of the air-conditioning system shall allow for a heat gain, due to artificial lighting of 8 W/m².
  • 1.7     Small Power Gain
    The design of the air-conditioning system shall allow for heat gain, due to small office equipment of 25W/m².
  • 1.8     Fresh Air
    Fresh air allowance of 12 l/s per person shall be provided for office areas at 1 person per 6 m²
  • 1.9     Environmental Control
    The offices will be comfort cooled by a Variable Refrigerant Volume (VRV) heat recovery system, with fresh air provided by multiple Heat Recovery Ventilation (HRV) Units on each floor.
    The heating/cooling and fresh air is control via an addressable control system providing grouped and individual control.
    Monitoring of the air quality within each floor will be undertaken by the BMS system.
    The Ground Floor Office Reception area are heated/cooled by a dedicated (VRV) heat pump system.
  • 1.10     Heating System
    Heating to the office floor shall be via the VRV system as described within the environmental control section. The VRV system shall be heat recovery type capable of simultaneous heating or cooling depending on zone requirements.
    No gas supply will be provided to the building for use by the offices.
  • 1.11     Soil & Wastewater System
    A fully vented soil system will be provided to remove the effluent from the various sanitary appliances throughout the cores. Dedicated soil and vent pipes with branch connections will be provided in the Cores to serve Tenant’s Tea Stations.
  • 1.12     Potable Cold Water Supply System
    The office boosted potable cold water mains supply will be provided and distributed through dedicated landlord’s risers to provide water to the toilet core. Valved and capped drinking water connections will be provided within each office floor for future tenants needs.
  • 1.13     Domestic Hot Water Service
    Domestic hot water is provided within the WC cores for use within the WCs be Wash hand basins. The tenant shall be provided with the ability to connection a cold water service to their demise only. Tenant hot water generation shall be by the tenant.
  • 2.0     Building Management System
    A BMS controls system will be provided to give fully automatic control of the HVAC Systems.
  • 3.0     Electrical Services
    The electrical installation shall be designed to the following criteria:
  • 3.1     General Lighting
    Lighting is designed in accordance with the CIBSE code for interior lighting to BS EN 12464-1-2011 office lighting. All lighting is LED providing energy efficiency and longevity.
    Addressable Lighting controls will include daylight management (dimming) to the offices and occupancy control to all spaces. Lighting shall be direct/indirect with hard wired lighting control modules.
  • 3.2 Lighting
    Office Lighting: 300 – 500 lux
    Core / WC Lighting: 150 - 200 lux
  • 3.3     Power
    Small Power Tenants   25 W/m²
    Lighting Tenants   8 W/m²
    Emergency Lighting 1 lux along defined escape routes in accordance with BSEN 1838 (BS 5266).
  • 3.4     Fire Alarms
    An analogue addressable Type L2 system protection of all escape routes from the building. Protection of life in accordance with BS 5839 part 1, with single stage evacuation.
  • 3.5     Life Safety Systems
    All life safety systems will be provided with an emergency generator supply via a change-over arrangement directly adjacent to the points of supply.
    The life safety system will comprise of:
    – Fire-fighting Lift
    – Life Safety Sprinkler System
  • 4.0     Energy
    The following details have been incorporated into the design to provide:
    – An air permeability rate of 5m³/h/m² at 50 Pa
    – Energy efficient lighting and heating and controls
    – Appropriate energy metering and monitoring
    – Highly efficient Air Source Heat Pumps, to provide heating and cooling. With a high COP and Seasonal efficiency rating
    These factors combine to provide the building with an  ‘A’ EPC rating.
