5. How can property developers create cost-effective sustainable developments?
• Cost Effective for who?
• Avoid complex designs
• Design & Build shortcuts
• Resist property agents &
institutional lenders requirement
for air conditioning
• Specify A or B rated EPC & DEC
• Specify BREEAM Outstanding
• Exceed Building Regulations
• Set energy targets
• Sign up to Green Leases

10. ENERGY EFFICIENCY
- Time Lapse during Earth Hour
• Implement a recognised
energy management regime
• Carbon Trust Standard
• BS-EN 16001
• Measure – Manage – Reduce
- Certify
• Set targets
• Use technology
• AMR Network of 400+
meters
• BMS
• Invest in energy efficiency

14. What technology is available for retrofitting old buildings?
NOT NECESSARILY ABOUT
NEW TECHNOLOGY – ITS ABOUT
USING IT EFFECTIVELY!
• CHP
• VSDs on Pumps and Fans
p
• PC control
• Voltage optimisation
• Fabric Improvements
• Lighting & controls
g g
• Heat recovery
• Solar thermal
KEEP IT SIMPLE &
INNOVATE

15. BUILDING ENERGY EFFICIENCY PROGRAMME - BEEP
• Energy Efficiency Retrofit
Programme at 42 GLA
buildings
• First significant energy
performance contract in
considerable time
• Supported by Clinton
Climate Initiative
• Desktop Audits
• Investment Grade
Proposals
• Delivers projects with ‘not
to exceed prices’
• And guaranteed energy
savings

16. PALESTRA – A sustainable case study
The brief…
• Improve BREEAM to Excellent
• Maximise
M i i recyclingli
• Payback within lease period
• Minimise energy & water
• Meet cycling requirements
15

17. Palestra
• >2000 staff relocated
• Modern, flexible workspace
• High user satisfaction rate
• Increased productivity
• Increased collaboration
between departments
16

18. Have Energy Performance Certificates been successful?
• ‘B’ Rating at Oxford Circus
House
• ‘B’ Rating at North Greenwich
• Both BREEAM Excellent
E cellent
• What will effect be on valuation? Oxford Circus House 14 Pier Walk, North Greenwich
• Really the need is for DECs for
all buildings
17

19. What are the waste management / onsite recycling options available?
18

20. What sustainable materials are most cost-effective?
• What is the definition of ‘cost-
effective’
• Depends on method of
evaluation
l ti
• Life cycle
• Fire rated
• Strength
• T i it
Toxicity
• Maintenance
19

21. Likely effect of recession on government and businesses’ commitment to zero
carbon?
• Less cash to invest
• Reluctance to invest
• Risk to fiscal measures
• Ri k t i
Risk to incentives
ti
• Enforcement of building
regulations
• Toned down Legislation - DECs,
CRC, EPCs,
CRC EPC EPBD II
BUT!
• Cheaper to borrow
• Insulate against utility spikes
• Improve asset value
• Greener is mostly cheaper!

22. RECOMMENDATIONS
• Invest in design
• Keep it simple
• Human as part of the machine
• Be inspired and innovate
• Consider Maintenance
• Consider cost and life cycle
• Use common sense
