In the UK, historically or architecturally significant buildings that are of special interest are protected by the English Heritage that makes every effort to preserve them. There are over 370,000 listed buildings in the country, and over 92% of them are considered ‘Grade II’. This means that any building work will require planning consent to prevent indiscriminate demolition and damage, and very little change is allowed specially on external elements. The majority of the Grade II listed buildings in the country are pre-1930s and consequently very energy inefficient, but are, nevertheless, occupied. In this paper, the authors present a study of architecturally sensitive energy efficient upgrade measures applied to a dwelling in the Royal Standard House, a Grade II listed building located in Nottingham, designed by Evans, Cartwright & Woollett and opened in 1923. Firstly, on-site field work gathered qualitative and quantitative data, such as comfort of occupiers, indoor daylight distribution, temperature variation and infrared thermography images. Secondly, the building was dynamically simulated with step-by-step envelope improvements considering different scenarios, and their impacts on comfort and energy performance were noted. Daylight distribution was also analysed to evaluate the impact of the building envelope changes on the daylit environment. The energy performances of the different scenarios were compared in order to evaluate the impact of the different refurbishment measures for existing buildings. The findings show that over 50% reduction on energy use can be achieved with no impact on the external character of the facade and with a minimum impact in the interior space. It was concluded that the fabric energy efficiency category of the Code for Sustainable Homes (CfSH) standard, normally applicable only for new-build, can be taken as a benchmark for a refurbishment. The results have also shown that a balance between optimum daylight distribution and thermal performance can be achieved with a holistic design approach.
