Environmental Sustainability
A computer fluid dynamic model of the building was created to assess the most appropriate building form and fenestration design. This ensures that the building works as a climate moderator and therefore can operate with less reliance on building services systems. The results of this analysis indicate that Broadway Two will perform to a higher standard than the notional SBSA benchmark building. As a consequence, the building's whole life costs will be reduced and this generates a capital saving with a consequent reduction in CO2 emissions. A mixture of low energy techniques have also been employed to enhance the energy efficiency performance of the building:
| • |
Broadway Two will benefit from external shading; this reduces the reliance on cooling. |
| • |
The Scottish climate will provide potential to cool the office space via a portion of free cooling. |
| • |
A low solar transmittance value for the glazing will minimise the level of solar gain entering the space: this again reduces the electrical cooling load. |
| • |
A lighting system which incorporates photoelectric daylight sensors will reduce
the reliance on artificial electric lighting. |
|
| • |
The energy consumption for lighting will be 12W/m2, while that of a notional building is 18.5W/m2. |
| • |
Good thermal insulation will keep heat loss to a minimum whilst an enhanced air permeability performance reduces energy loss further. |
| • |
Target BREEAM – 'Excellent'. |
| • |
Target EPC – B.
