03. Heriot Watt University SurveyThe Project Background Our Commission, Estate Condition and Compliance Survey Condition of Fabric & Infrastructure DDA Audit Asbestos Data Fire Data Energy Performance of Buildings in Relation to EU EPBD

03. Heriot Watt University SurveyThe Project Background Riccarton Campus Statistics Approximately 100 Hectare Site 100 Buildings 170,000 Sq.M. of Floor Area 9000 Individual Room Spaces Property Age Range in Excess of 200 Years Very Wide Range of Building Use

Stage 1 Construction Data Site Survey Data 03. Heriot Watt University Survey Data Capture From Drawings And Specification Built Form Use Plant And Equipment Real World Information – Up To Date Fabric, Condition And Use The Carbon Emission Rating Process

Stage 2 Build 3d Geometry 03. Heriot Watt University Survey Start Computer Model From Acquired Data Floors Walls Openings Roofs Stairs & Lifts The Carbon Emission Rating Process

Stage 3 Maintenance Attach To All Individual Spaces & Components Environmental Data 03. Heriot Watt University Survey Attach Attributes To Geometry Update And Check System Static Data Set Appropriate Settings, Conditions, Values And Rules Building Data Activity Data Lighting Data Heating Data Location And Weather Model The Carbon Emission Rating Process

Stage 4 Run Actual Run Notional Results 03. Heriot Watt University Survey Simulations On Building As Built With Actual ‘U’ Values Based On Building As If Compliant With Current Regs. (Part L 2006) Kg Carbon Dioxide per Sq.M. The Carbon Emission Rating Process

Stage 5 Compare Outputs Produce Certification Log Book 03. Heriot Watt University Survey Outputs Determine Relative Emissions Actual Carbon Emission Notional Carbon Emission Relative Emission Performance (%) Index Rating Against Scale (EPBD/Relative) All Background Material And Ancillary Data The Carbon Emission Rating Process Actual Notional X 100 (%)
