To ask the Scottish Executive what methodologies it has considered using in respect of non-domestic buildings in order to comply with Article 3 of the EU Energy Performance of Buildings Directive and what the estimated cost per survey would be of using each methodology.
I have asked Dr. PaulStollard, Chief Executive of the Scottish Building Standards Agency (SBSA), toanswer. His response is as follows:
The SBSA has to dateconsidered using the Simplified Building Energy Model for non-domesticbuildings, although it is likely that in the future some commercial detailedsimulation models will be available and suitable for use. No assessments havebeen undertaken regarding the cost of using the different methodologies ashourly and daily rates vary from company to company or from sole trader to soletrader. Independent research has, however, established the following datacollection times for existing buildings:
Three days for very largebuildings.
One day for average sizebuildings.
