BRE Report: delivering sustainable buildings does not add significantly to costs

A new report by BRE and Sweett Group challenges the view that sustainable buildings are more costly to construct. The report shows that achieving lower BREEAM ratings can incur little or no additional costs.

The report’s authors applied cost data from real construction projects to three case study buildings – an office, secondary school and community healthcare centre – to obtain detailed capital and operational cost information.

The report also examines the life-cycle costs of operating buildings, focusing on energy and water consumption, and found that specifying sustainability measures during the building’s design and procurement stage can result in cost savings over the operational life of the building for little or no additional upfront cost.
