    Abstract

    The aim of this project was to investigate the embodied energy implications when redeveloping office spaces into residential use.

    A critical literature review was undertaken to establish what information there currently is regarding embodied energy within the construction industry. It was demonstrated that the lifecycle of a building project comprises; Product; Construct; Use and End-­‐life. It was deemed to be beyond the scope of this project to investigate the embodied energy of all these stages. The result of the literature review however indicated the importance of one area, ‘Product’, which, in this case can be seen as the production and selection of materials for construction. As such, it was decided that this investigation should look specifically at the embodied energy in construction materials.

    Three investigations were carried out. These were;

    • A case study to investigate the embodied energy associated with the redevelopment of an existing office space compared to a re-­‐build. This required 3D computer modelling and a spreadsheet based calculation.
    • The production of a questionnaire aimed at selection of construction industry experts, namely civil engineers, construction managers, architects, quantity surveyors, property developer and environmental engineers.
    • A targeted and planned interview with a professional expert from the sustainability consultants, Building Research Establishment (BRE).

    The results of each approach complemented each other as they all acquired different types of results regarding embodied energy in an office space redevelopment. The case study concluded that 93% of material embodied energy could be saved when redeveloping office spaces as opposed to a new build of the same size. The questionnaire looked at the construction industry’s attitudes towards embodied energy and shed light on the widely shared attitude regarding the capability of BIM and how it can and will be used in the future to hold information and undertake analysis on all aspects of embodied energy. Finally the interview established how the construction industry can be improved regarding sustainable construction and embodied energy, and how it may even be Finally the interview established how the construction industry can be improved regarding sustainable construction and embodied energy, and how it may even be necessary to allow for Government intervention to impose taxation on materials with large amounts of embodied energy. Similarly, the Government may need to intervene to ensure that local planning authorities do more to promote sustainable construction and enforce guidelines.
