2. GREEN BUILDING
Both a structure
and the using of
processes that
are
environmentally
responsible and
resource
efficient
throughout a
building’s life
cycle.

• 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

8. 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

11. Minimum Standards

12. 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.

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 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

17. NATURAL LIGHT
 cellular offices swept away, leaving large, uncluttered floorplates open to the atriums, allowing natural light to flood in

18. 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.

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
• 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

21. • 1,040kW of electricity
• 800kW of cooling
• 20% of the building’s heat
requirement.
• COLLECT
• FILTER
• REFINE

22. • 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.

23. 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%.

INTRODUCTION

26. • 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

27. South facing to
maximize solar gain
300,000 sq ft
exposed concrete,
which acts as a
thermal sponge

28. Site orientation

ORIENTATION AND FLOOR PLANS

29. • 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

31. 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

33. 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

34. • 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
