AN ADVANCED REFURBISHMENT EVALUATION METHODOLOGY FOR MODERNIST OFFICE BUILDINGS

The energy used in non-domestic buildings accounts for 18 % of the energy use in the UK. Modernistoffice buildings, typically defined as those built between 1945 and 1985, represent a promising sectorfor refurbishment and energy demand reduction. This paper aims to present an advancedmethodology for refurbishing modernist office buildings. The methodology involves creating anarchetypal building model which is assessed by using sensitivity analysis to evaluaterepresentativeness and develop insight into the most effective refurbishment design parameters. Forthis, a parametric study, using dynamic thermal simulation modelling, was undertaken for arepresentative modernist office building model, located in London, UK. Combinations of heating andpassive cooling refurbishment measures were applied to the representative model. The resultsshowed the suggested methodology provides an improved understanding of refurbishment solutionsand draws out useful pathways to enhance existing approaches to refurbishment.
