1 Wayne Howatt 01. Welcome The Climate Challenge Director, Dearle & Henderson for Scottish FHE Institutions

2 Nature of Business Established Size Coverage Major Disciplines 02. Introduction Property & Construction Consultants Staff UK Wide and Oversees Design Building Surveying Compliance Quantity Surveying Project Management Energy & Sustainability Our Company

3 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

4 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

5 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

6 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

7 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

8 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

9 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 (%)

10 Stage 6 Changes To Properties Future Proposals 03. Heriot Watt University Survey Maintain Model Update To Reflect Any Changes To Relevant Features Or Attributes Future Compliance Issue Develop Use Of Model As A Tool Assess Value/Benefit Of Proposals A Basis For ROI Calculations The Carbon Emission Rating Process

11 04. Design SolutionsUsing The Model As A Design Tool

12 Cost Sustainability Flexibility Future proof Maintenance Running Costs Security Functional Value Sustainable 3 Possible Routes 04. Design SolutionsEnvironmental Engineering Requirements

13 04. Design SolutionsEnvironmental Engineering Requirements Natural / Passive Openable Windows Natural Ventilation Stack Driven Ventilation Solar Shading Ultra Low U Values Renewable Energy Sources Commercial Standard Non-Openable Windows Mechanical Ventilation Refrigerant Cooling Lightweight Building Standard U Values Fan Coils VRV etc. Low Energy Engineered Choice of Open/Non-Openable Windows Mechanical Ventilation Renewable Energy Techniques Peak Summer Temp. Control Innovative Cooling Techniques

14 04. Design SolutionsConceptual Development Consider parkland / urban visibility - views general arrangement Public / private – security sustainability future flexibility internal movement natural daylight materials custody suite organisation operations / fsu relationships

15 Modelling Techniques04. Design Solutions

16 Fundamental Systems Integration

17 Main office accommodation on north face, which is shaded and cool Sealed façade to reduce noise from adjacent highway NOISE Solar panels following the sun path could provide a percentage of renewable energy Potential for green roof to reduce heat gains and improve thermal insulation Ground source heat pump could provide a considerable percentage of free energy 04.
