  2. 2. GREEN BUILDING Both a structure and the using of processes that are environmentally responsible and resource efficient throughout a building’s life cycle.
  3. 3. • Structure design • Energy efficiency • Water efficiency • Material efficiency • Waste and toxic reduction FUNDAMENTAL PRINCIPLES OF GREEN BUILDING COMMON OBJECTIVES OF GREEN BUILDING • Efficiently using energy, water and other resources • Protecting occupant health and improving employee productivity • Reducing waste, pollution and environmental degradation
  4. 4. ENVIRONMENTAL BENEFITS ECONOMIC BENEFITS SOCIAL BENEFITS Enhance and protect bio diversity and ecosystem Reduce operating cost Enhance occupant health and comfort Improve air and water quality Improve occupant productivity Improve indoor air quality Reduce water streams Enhance asset value and profits Minimize strain on local utility infrastructure Conserve and restore natural resources Optimize life cycle economic performance Improve overall quality of life Social Development Economic Growth Environmental protection SUSTAINABILITY
  5. 5. DEMERITS • Efficient Technologies • Easier Maintenance • Return On Investment • Improved Indoor Air Quality • Energy Efficiency • Water Efficiency • Waste Reduction • Temperature Moderation • Water Conservation • Economical Construction For Poor • Healthier Lifestyles and Recreation • Improved Health • Initial Cost Is High • Availability Of Materials • Need More Time To Construct • Need Skilled Worker MERITS
  6. 6. Impacts of buildings alone on resources
  7. 7. First launched in 1990 BREEAM- WORLD’S FIRST BUILDING ASSESMENT SYSTEM • Inspires developers and creators to excel, innovate and make effective use of resources. • Focus on sustainable value and efficiency • BREEAM certified developments attract property investments and generates sustainable environments that enhance the well-being of the people who live and work in them BREEAM in numbers worldwide 552,968 Certificates 2,254,176 Registered Buildings 77Countries WORKING CRITERIA
  8. 8. BREEAM New Construction BREEAM International New Construction BREEAM In-Use BREEAM Refurbishment BREEAM Communities Types of buildings assessed Rating system
  10. 10. Minimum Standards
  11. 11. PROCESS Innovation Credits Awarded for either 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.
  13. 13. PWC'SLONDON OFFICE • Client: PwC • Architect: TP Bennett • Project manager: Turner & Townsend • M&E engineer / BREEAM assessor: ChapmanBDSP • Structural engineer: Arup • Contractor: Overbur • Location: London, near Tower Bridge in central London • BREEAM score of 96.31 % • The first BREEAM “outstanding” rating
  14. 14. 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.
  15. 15. OLDBUILDING • Entrance particularly depressing. “ 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
  16. 16. NATURAL LIGHT  cellular offices swept away, leaving large, uncluttered floorplates open to the atriums, allowing natural light to flood in
  17. 17. SUSTAINABILITY FEATURES LANDSCAPING  hard and 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.
  18. 18.  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.
  19. 19. INNOVATION CREDITS • a biofuel 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
  20. 20. • 1,040kW of electricity • 800kW of cooling • 20% of the building’s heat requirement. • COLLECT • FILTER • REFINE
  21. 21. • thermal panels in 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.
  22. 22. Utility bill saving of £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%.
  24. 24. • Co-operative Group’s new 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
  25. 25. • Fully glazed double 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
  26. 26. South facing to maximize solar gain 300,000 sq ft exposed concrete, which acts as a thermal sponge
  27. 27. Site orientation Floor plans Top floor plan ORIENTATION AND FLOOR PLANS
  28. 28. • Low energy LED lighting & IT equipments • Greywater and rainwater recycling systems for toilet flushing • High efficiency passenger and service lifts SUSTAINABILITY FEATURES • Earth tubes to bring in cool air via a heat exchanger • Waste energy -> absorption chiller -> cools the building • Heat recovery from the IT systems -> heats the building • Combined Heat and Power (CHP) plant fuelled by waste cooking oil and rapeseed oil produced on own farm • Electrical car charging points
  29. 29. Color changing lights with daylight sensors- sense & measure natural light, triggering the fixtures to only emit as much light as necessary, increasing energy savings and sustainability
  30. 30. READY FOR GLOBAL WARMING! Future-proofed against forecast 2050 temperatures – a predicted 5% percent increase in temperatures & 30% more rainfall in winter • On the external outer skin, additional £120,000 for a bronze anodised rather than powder-coated finish Lifetime guarantee of reduced maintenance costs. • Digital storage policy reduced the amount of paper the business used. • Same amount of paper as before -> Additional 4 stories needed for storage alone. No longer paper mail delivered to the building
  31. 31. • Energy Plus Building(EPB)- produces more energy than imports • £110 million investment £ 142 million lease for 25 (2013) 80 PERCENT FEWER CARBON EMISSIONS 50% LESS ENERGY CONSUMPTION 30% REDUCTION IN OPERATING COSTS SAVES £500,000 PER ANNUM
