This 90 acre site adjoining junction 18 of the M1, north of Crick in Northamptonshire was acquired in March 2005. The site was formally used as an abattoir, for pet food manufacture and distribution operations.
Following extensive consideration of the site constraints and opportunities, we initially approached the Local Authority with our outline proposal in September 2005 and as part of formulating the redevelopment proposals and in accordance with the recommendations of Daventry District Council we undertook a Community Involvement Exercise in Crick during February 2006 taking the form of a public exhibition which was received as a resounding success.
Our proposal incorporated the demolition of all the current buildings and a redevelopment of the site to provide a single 1,250,000 sq.ft. distribution building and a further, smaller 250,000 sq.ft. building.
The full Planning Application was submitted in June 2006 following a very comprehensive and detailed analysis of the site specific constraints in engineering, planning and environmental terms. As a consequence of our approach, detailed planning consent was granted in January 2007.
Fundamental to our success was our approach to sustainability which was based on the following objectives:
- Fully examine and comprehend the key sustainability themes in relation to the development proposals;
- Identify the performance of the development proposals in relation to each of the themes; and to
- Identify sustainability objectives and the appropriate ‘actions required’ to ensure that sustainability is delivered during and in the ‘built form’.
Bio Diversity, Flora and Fauna
A major commitment was made to habitat creation and overall enhancement of the ecological value of the site. Our overall design was influenced by the identification of ecological constraints and opportunities on the site with the intention to design out any potential impacts. This is achieved by:
- Realignment of the existing brook with a broader and ecologically led planting and a habitat creation strategy.
- Providing approximately 11 Hectares of new landscaped planting. See below summary.
|Type ||Area ||Number |
|Woodland Tree planting ||5.7ha (14 acres) ||43,772 |
|Woodland shrub planting ||3.5ha (8.6 acres) ||24,735 |
|Meadow grass ||0.62ha (1.53 acres) || |
|Aquatic planting ||0.94ha (2.32 acres) || |
|Specimen trees ||215 || |
|Ornamental shrubs ||0.35ha (0.86 acres) ||13,932 |
|Total ||11.11ha (27.45 acres) ||82,864 |
|Percentage of the overall site area ||28.69% || |
- Planting is introduced on a very large scale which transforms the landscape assets of the site and indeed the surrounding area and increases commensurately the extent, range and value of habitats. Overall, the planting provisions add up to a total of some 44,000 woodland trees and with some 27,500 woodland edge shrubs: with meadow, aquatic and formal planting total of 83,000 plants.
- Realignment of the existing footpath through the new landscaped woodland area.
In terms of improving energy efficiency a number of measures are included in the detailed design to ensure that the best practice energy consumption can be achieved: The offices have been designed externally from the warehouse to ensure:
- The orientation provides maximum exposure to the sun path, providing natural light therefore maximising daylight
- 10% – 15% roof lights to the warehouse areas to maximise daylight and reducing energy consumption for lighting
- Natural ventilation will be adopted wherever feasible to reduce size of cooling plant within the offices
- Provision of solar shading via the building form is being provided
- Enhanced insulation will be provided to reduce heat loss in the building fabric
- Low levels of air permeability will be achieved – target 5mcu/hr/m sq
- Lighting within the offices will be controlled using PIR sensors with automatic daylight dimming control to ensure only active areas of office are lit
- Low energy lamp sources will be utilized to reduce energy use
- High efficiency plant will be selected with guidance provided to the occupier on efficient use and operation
- The loss of energy and thermal loss will be reduced through enhanced insulation to pipework and ductwork installations
Renewable Energy Sources
We have adopted a target of 10% of the buildings energy requirements are to be provided via renewable sources. This will be achieved through a combination of:
THE BOILER IS EXPECTED TO CUT SOME 230 TONNES OF CO2 ANNUALY.
Domestic water use will be restricted to reduce energy further by:
- Installing water efficient staff showers
- Installing spray taps over and above the current requirements for low water content WCs.
- Harvesting rain water from the roof and reusing in the building for grey water recycling in the toilets and for irrigation of the new landscaped areas.
WITH ALL THESE PROPOSED SAVING THE kgC SAVED WOULD BE 4279kgC
A full assessment has been made of the potential greenhouse gas emissions (GHG) arising for a “Base Case” development and an “Actual Design” case, to establish the carbon footprint benefits which result from the incorporated design upgrade features.
- By modifying the site layout and levels at the design stage we are able to significantly reduce the volume of material being disposed off site, thus reducing transportation and PROVIDING A SAVING OF 678 TONNES OF CO2
- By using low carbon intensity construction materials we can ACHIEVE A SAVING OF 660 TONNES OF CO2
- By ensuring contractors use plant with lower GHG emissions it is estimated A SAVING OF 139 TONNES OF CO2 WILL BE ACHIEVED
