Following the successful renovation of the external facade at 18 Belgrave Square, the Austrian Embassy, NBA were commissioned to continue the work on the internal elements of the Grade I listed building.
In conjunction with M&E, Engineers Environmental Engineering Partnership, NBA were able to develop the principles of providing a sustainable solution to working on a Grade I listed building. Specific design solutions were aimed at replacing the overall heating system, both water and air based, in line with current best practice guidelines within the fabric of the 200 year old building. Particular attention was paid to the sympthetic insertion of heating and ventilation elements within the existing interior furnishings. New radiator grilles and wall panels had to be inserted to match existing features and colour schemes.
Whilst double glazed units were accepted in some areas the key facades were only permitted to include secondary glazing elements. careful specification helped to reduce not only the heat loss from these areas but also improve significantly the acoustic performance of the windows. Bedrooms were the greatest benifactor of these improvements along with the Ambassador's study!
The overall air filtration rate was improved by three times the original rate leading to significant energy biill savings to the whole Residence.
