In addition to the initiatives already embedded in this specification, we will work with our customers to establish an Eco-features budget for the development which may be used on a number of technologies, the purpose of which is to reduce the operating carbon footprint of our buildings.
These may include:

  • Wind-generated power
  • Photovoltaic
  • Ground source heat pump
  • Air source heat pump
  • Solar wall/energy wall
  • Combined heat and power
  • Uprating thermal performance of roof lights
  • Biomass boilers
  • Biomass CHP
  • Energy from waste
  • Electrical off-peak power control
  • Central heat recovery on fit-out
  • Passive ventilation where office dimensions allow
  • Night-time cooling within fit-out design
  • BMS system within fit-out design
  • High efficiency fans on all systems
  • CO2 sensors to control VSD fans to ensure that air is delivered only when required

In addition to the initiatives already embedded in this specification, we will work with our customers to establish an area within the demise, behind the security line, where, within the landscaped area a small, level, grassed area accessible from the car park, circa 20 metres × 6 metres, together with a small timber shed, can be allocated for the future location of an apiary area for the use of local British Beekeeping Association members. All subject to the full agreement with the operator and subject to the operator permitting regular access though their security line.

Design criteria

  • Offices to be positioned externally from the main warehouse
  • Offices to be either 10 or 14m deep
  • Light and airy reception
  • Floor-to-floor dimension to be 4.2m overall
  • Operationally sub-divisible
  • Ability to provide extra yard depth (min 36m / ideally 56m)
  • Ability to provide canopies above level-entry doors
  • Warehouse frame spacing to be 8.0m and docks to be 4.0m centre to centre
  • Provision of HGV parking spaces at circa one per 4,000 sq ft of warehouse
  • Provision of minimum of 20% car charging spaces
  • Loading dock ratio of one per 5,000 sq ft of warehouse minimum
  • Below-ground services for the future provision of warehouse offices – ducts and drainage
  • Stacking at gatehouse to be a minimum of three articulated vehicles
Electrical services

2000kVA low loss of the MIDEL liquid-filled type (KNAN).

Main LV panel
The LV Switchboard will have sufficient outgoing ways to cater for the developer base build services with 25% spare capacity.

Automated monitoring and target system
The electricity metering strategy is required to be designed and operated in line with Part L2 of the building regulations and GIL065 (Guideline for sub-metering new build premises), and CIBSE: TM39 – 2006. The main LV panel and sub-distribution boards are fitted with pulsed / open protocol meters that measure the building’s energy consumption in line with Part l2 building regulations. The sub-meters are linked to the BEMS system.

Over-door busbars
Overhead IP54 rated plug-in busbar systems are provided for all dock leveller doors level access doors.

Main offices power
Generally, within the first and second floor office areas with raised access floors, power is provided via 4-compartment flush floor boxes, at a ratio 1 per 9 sq m. Each floor box is complete with two twin general switched sockets, one quad data plate for future data installation, and one blanking plate.

The flush floor boxes are supplied from the floor void below, via under-floor power high-integrity earth busbars.

Each floor box is supplied with a 3m mains connection lead. Two No 25mm flexible conduits shall be provided and installed for use by the data specialist. All other areas by 3-compartment dado trunking.

All toilets are fitted with White Dyson Airblade hand dryers.

Disabled refuge call system
The system consists of a single master station, located within the reception area and outstations.

Office lighting
Ultra-high efficiency LED, has been fitted to the office areas, with in excess of 100 lumens/circuit watt. This is combined with presence detection and daylight linking controls (for two rows near windows). The life expectancy of the LED fittings is in excess of 50,000 hours.

External LED lighting
Ultra-high efficiency LED lamps, with in excess of 110 lumens/circuit watt, have been installed. Each fitting is provided with a wireless mesh node for ultra-flexible control and is fixed to the building/lighting columns (8m affl). Luminaires are fixed in horizontal plane for zero upward light spill in compliance with ILE Dark Skies policy. Each LED fitting will have a life expectancy of over 50,000 hours.

Electric car chargers
Electric car charging has been installed to cater for 20 car charging points in the main car park. Duct infrastructure has also been installed to facilitate extension for an additional future 60 cars to meet the projected increase in electric vehicles on the road forecast in the next 20 years.

Mechanical services

Office heating and cooling
The office heating and cooling system is designed and installed in accordance with CIBSE TM13-2013.

The Main Office reception, rst and second oor open o ce areas, North and South Pod first floor open offices are heated and cooled by a Hydronic VRF system via an Air Source Reverse cycle heat pump. This significantly reduces the extent of refrigerant charge.

Low-temperature hot water
The LTHW heating is provided by a high-efficiency low NOx (≤40mg/kWh) gas-fired modular floor standing system condensing boiler(s).

Hot water systems
Hot water to all Main Office toilet areas is provided via indirect HWS calorifiers in conjunction with a solar heating backup system on the Main Office plant only.

Rainwater harvesting system
External below-ground rainwater harvesting system (12000 litres) is provided to the main office. The water is utilised for urinal and WC flushing, greatly reducing tenants, water usage.

Office heating and ventilation
The offices’ heating/ventilation is provided by heat recovery air handling units.

The controls systems are provided with TREND IQ outstation that can be interfaced with a future tenant TREND BEMS installations

Sensor taps/low-flush WCs
Sensor taps are provided to the main toilet facilities for water savings. Low-flush WCs (4/6 litres) are also provided which when combined with rainwater harvesting systems will mean lower water usage.

Major water leak detection
Each incoming water position to the building is monitored with alarm links to the BEMS, which identifies up any out-of-range readings/leaks. This is an early warning system prior to visual leak detection.

Variable speed drives on pumps/fans
Variable speed drives will be installed on pumps and fans to match the fan/pump flow rates with the actual requirements. This saves on electricity usage and CO2 emissions.

Solar thermal
Solar thermal system will be provided to pre-heat the office hot water system and save on gas usage and therefore CO2 emissions.

Excellent airtightness of building (in excess of building regulations requirements)
The building will obtain an excellent air tightness of 1m3/ (m2·h) @50 Pa or better which greatly exceeds 5 m3/ (m2·h) @50 Pa requirement of building regulations. This will reduce the warehouse heating costs and thus gas usage and CO2 emissions.

15% roof lights
The warehouse is provided with 15% GRP roof lights which will be evenly distributed on the north/south facing roof slopes. This will provide an excellent daylight factor of approx 3% which, when combined with daylight, controls reduces the electricity usage and CO2 emissions of the warehouse lighting installation, when installed.
