The Energy Cost Metric (ECM) is anticipated to provide a novel and meaningful approach to designers to achieve very-low energy designs at early stages of the design project, without undue cost. It also serves as a common method and language between beneficiaries, project managers, architects, engineers, contractors and quantity surveys, where matters relating to capital cost, sustainability and energy use can be debated in an inclusive and holistic manner.

In this report, the ECM used to design Civil Engineering Building (CEB) was explained and then tested in practice with outside partners on the CEB development project. This report includes the following design stages: the Brief to Design, the Concept Design and early Developed Design (Stages 1-3 according to RIBA Plan of Work 2013) and consists of 5 main chapters: Meeting Sustainability Requirements; Energy Brief for Civil Engineering Building; Energy Cost Metric; Application of Metric; and Discussion and Conclusion.
