Compliance Monitoring

• Employers Requirements sets targets for all key
  issues including energy and daylight
• Complex procurement method through original
  client, a developer and contractor
• Department for Constitutional Affairs
• Allied London Properties, Developer
• Bovis Lend Lease, Contractor
• Multiple compliance monitoring activities

Borehole Cooling

• Needs licence from Environmental Agency
• Licence needs renewing every 6 years
• Requires additional monitoring borehole
• Client must accept associated risks

Results

• Excellent BREEAM rating
• Energy consumption some 16 less than required by
  Building Regulations
• Carbon emissions savings equivalent to removal of
  135 cars
• Running cost savings of about 1.6m over the 25
  year lease.
• Chiller COP increased to 6.2 from 5.1
• Building leakage test results 28 better than
  regulations

53
Steps to sustainable design

• Client, architects and engineers to work together
  from the start
• Sketching and estimating is vital to developing a
  successful concept
• The whole to be better than the sum of the parts
  but with energy as a key driver, especially now
• Good ideas to be quantified early in the
  process
• For progress, feedback from innovative projects
  is vital

54
Architectural Competitions

• They encourage new concepts and ideas at
  competition stage
• They may stifle detail design development later

55
Summary

• Low energy considerations have informed the
  engineering and the architecture from the start
• The building is complex, innovative, iconic
• The brief targets have been met
• User feed back is positive
• Energy in use is still to be assessed
