- 12. PROCESS Innovation Credits Awarded foreither complying with pre- defined BREEAM issue exemplary level requirements, through the appointment of a BREEAM Accredited Professional or Suitably Qualified Assessor or process approved as ‘innovative’. Fees On top of the BREEAM assessor fees for the time allowance, BRE certification fees must be paid. Currently these are around £1,230. Additional fees apply for BREEAM Other Buildings. Timeframe From three months to three years depending on the type of building, type of assessment, project programme and how quickly the required documentation is provided by the project team to the BREEAM Assessor.

- 15. KEYFACTS •Stage: Post-Construction •BREEAM version:BREEAM 2008 Offices • 40,000m2 total floor area • Ground floor below the station • floor 1 to 9 above with structure, services and lifts passing through Charing Cross station.
- 16. OLDBUILDING • Entrance particularlydepressing. “ heavy, monolithic and dark with a fountain that stank of chlorine.” • Removal of fountain • Vertical circulation difficult • hidden away stairwells • overused lifts REFURBISHMENT inserting an open stair in the south atrium Two scenic lifts inserted into the north atrium plenty of breakout spaces, meeting rooms and quiet spaces for uninterrupted work. REFURBISHMENT TWO HALVES 5-9 FLOOR FIRST The ninth floor breaks the orthogonal open-plan office mould. Light through the glazed, barrel-vaulted roof
- 17. NATURAL LIGHT cellularoffices swept away, leaving large, uncluttered floorplates open to the atriums, allowing natural light to flood in
- 18. SUSTAINABILITY FEATURES LANDSCAPING hardand soft landscaping work break-out areas to be created on each of the terraces emphasis on the use of recycled materials CONTRIBUTE EIGHT POINTS installation of new paving, recycled composite decking, bed construction using recycled plastic boards • level two a stainless steel wire living wall, with climbing plants established in pots at the base. • level eight, installed two large galvanised and powder-coated frames to support pots filled with soil and pre-grown ivy.
- 19. Level ten,micro-habitat , encourages specific bird species such as the Black Redstart, the Linnet, and the House Sparrow. Level seven, provides foraging and breeding for birds, and attracts bees, butterflies, hover flies and other invertebrates. 1300 square metres of roof space dedicated to support threatened and protected species of birds and invertebrates.
- 20. INNOVATION CREDITS • abiofuel powered tri-generation unit that provides heat, cooling and power. • bump the building up from an EPC “B” to an “A” CONTRIBUTE 15 POINTS • powered by biodiesel made from waste vegetable oil • waste oil from central London's restaurants • huge amount of savings with particulates, carbon, Sulphur dioxide
- 21. • 1,040kW ofelectricity • 800kW of cooling • 20% of the building’s heat requirement. • COLLECT • FILTER • REFINE
- 22. • thermal panelsin More London are used to provide hot water for the washrooms. • active chill beam system, which is a very efficient way of, of passing chilled water throughout the building and enabling us to cool the occupants in a very sustainable way.
- 23. Utility bill savingof £250,000 a year, but PwC forecasts more: electricity (-221%); gas (-11%); and water (-33%). • Today building emits 40% less carbon than one typical of its size; and 20% of heat and 60% of its energy needs are produced on-site. • The refurbishment is expected to pay for itself in less than four years • PwC's 2017 targets to reduce carbon emissions by 50% and energy use by 25%.

- 25. • Co-operative Group’snew 15 storey headquarters • BREEAM Version: BREEAM Offices 2008 • Stage: Final Post-Construction • Score: 95.16% • BREEAM rating: Outstanding Architects: 3D Reid Location: Miller Street, Manchester, UK Area: 328000.0 ft2 Project Year: 2012 Client: The Co-operative Group Project manager: Gardiner & Theobald Structural and M&E engineer: Buro Happold Contractor: BAM INTRODUCTION
- 26. • Fully glazeddouble skin façade minimize heating and cooling loads • Summer- Ventilation: Louvres at top open to allow the warmed air trapped between its inner and outer skins to rise up and out of the building • Winter- Insulation: Louvres close so the facade can form an insulated blanket around the building KEY FEATURES • 15 Storey atrium- floods the building’s interior with light • Light reflected by the exposed white painted concrete coffered floors, reducing required artificial lighting from 550 to 300 lux. • Used building information modelling (BIM) to create building before construction to prevent unnecessary wastage of materials and time
- 27. South facing to maximizesolar gain 300,000 sq ft exposed concrete, which acts as a thermal sponge
