  24. 24. Reduced CO 2 emissions The combined effect of the passive and active designs produce an improvement of 35% over the 2006 building regulations. BCO Bench mark less than 40 (B) EPC rating 37 (B) 717 MWh/yr £73,000/yr 255 tons of CO2 New build bench mark 79 (D) Existing stock 146 (F) Predicted annual energy saving over EA existing buildings is £144,000 and 661 tonnes of CO2
  25. 25. Horizon House Summing Up
  26. 26. Has property changed the business? – Business efficiencies – multiple sites into single site, aggressive utilisation target – Reduced environmental impact – BREEAM excellent, energy and water efficient building – Demonstrate that being green makes business sense – Improved culture, inspired staff, attract talent. – Visible champion for the environment.
  27. 27. Has property changed the business? – Expected £1m pa excluding energy savings – 74% of staff used to commute by car, staff travel plans suggest only 14% continue to use car. 2500 commuter miles per day – Best BREEAM Office for 2010, reduction in water consumption, B rated building – Energy savings of B rated building over C rating for 20 year lease = £820,000 Saving From F rated old stock = £2,860,000 (current cost) – Improved culture, inspired staff, attract talent. TBC – Visible champion for the environment - TICK
  28. 28. Lessons learned so far. – Businesses looking for property want more than £x per sqf. – An energy efficient, sustainable building will be more attractive to end tenants. BREEAM and Renewable Energy is no longer a nice to have. – Choices to make – what is sustainable? Performance based contract. – BREEAM can throw up interesting choices. – Consider fit out procurement when procuring base build. – High utilisation and space efficiency can be delivered through reflecting on how your people work. Ensure the right support services are in place.
