Model for the environmental impact assessment of neighbourhoods - Damien Trigaux

  1. 1. DAMIEN TRIGAUX MODEL FOR THE ENVIRONMENTAL IMPACT ASSESSMENT OF NEIGHBOURHOODS DOCTORAL SEMINAR ON SUSTAINABILITY RESEARCH IN THE BUILT ENVIRONMENT | DS²BE SEMINAR | BRUSSELS |19.03.14
  2. 2. 2 [CONTENT] 1. STATE OF THE ART 2. OBJECTIVES 3. METHODOLOGY 4. RESULTS 5. CONCLUSIONS DAMIEN TRIGAUX | DS²BE SEMINAR | BRUSSELS |19.03.14
  3. 3. 3 [STATE OF THE ART] BUILDING SUSTAINABILITY ASSESSMENT METHODS (BSAM) § Scoring tools § MulD-­‐criteria assessment § Wide range of sustainability issues (e.g. energy, materials, water and comfort) § Life Cycle Assessment (LCA) tools § EvaluaDon of the life cycle environmental impacts § ScienDfic base § Limited to the micro-­‐scale (individual buildings) and environmental aspects [Trigaux, D., Allacker, K., De Troyer, F., DAMIEN TRIGAUX | DS²BE SEMINAR | BRUSSELS |19.03.14 Compara(ve analysis of Building Sustainability Assessment Methods for neighbourhoods, Architecture and Sustainability: Cri(cal Perspec(ves, not yet published] SCORING TOOLS LCA TOOLS ARIADNE
  4. 4. 4 [OBJECTIVES] MAIN OBJECTIVE ElaboraDon of an assessment method for the DAMIEN TRIGAUX | DS²BE SEMINAR | BRUSSELS |19.03.14 evaluaJon of sustainability in neighbourhoods § Integrated life cycle approach, combining Life Cycle Assessment (LCA) and Life Cycle CosDng (LCC) calculaDons § Quality assessment: mulD-­‐criteria analysis (MCA) § Decision support tool (helping decision makers like architects, urban planners, engineers and policy makers) § Applicable during the different design phases BUILDING IMPACT BUILDING QUALITIES ECONOMIC SUSTAINABILITY Life cycle cosJng (LCC) ENVIRONMENTAL SUSTAINABILITY Life Cycle Assessment (LCA) VALUATION ENVIRONMENTAL IMPACTS QUALITIES FOR USERS MulJ-­‐criteria analysis (MCA) SOCIAL SUSTAINABILITY Social life cycle assessment (sLCA) VALUATION SOCIAL IMPACTS QUALITIES FOR SOCIETY MulJ-­‐criteria analysis (MCA)
  5. 5. 5 [OBJECTIVES] SUB-­‐OBJECTIVES 1. Extension DAMIEN TRIGAUX of the scale of the individual building | DS²BE SEMINAR | BRUSSELS |19.03.14 to clusters of buildings and neighbourhoods 2. Extension of the evaluaJon scope (e.g. impact assessment of commuter transport, water consumpDon and building site land use, evaluaDon of society related qualiDes)
  6. 6. 6 [METHODOLOGY] LIFE CYCLE APPROACH § Impact assessment over the DAMIEN TRIGAUX whole building life cycle | DS²BE SEMINAR | BRUSSELS |19.03.14 (from cradle to grave) § Based on exisDng LCA methods: SuFiQuaD (Sustainability Financial and Quality evaluaDon of Dwelling types) and MMG (Milieugerelateerde MateriaalprestaDe van Gebouwelementen) PRODUCTION raw materials transport manufacturing construction activities LCA USE cleaning maintenance replacement heating END-OF-LIFE demolition transport waste processing and disposal CONSTRUCTION transport
  7. 7. 7 [METHODOLOGY] ELEMENT METHOD FOR COST CONTROL § Hierarchical subdivision in § Neighbourhoods as a combinaDon of DAMIEN TRIGAUX funcJonal elements | DS²BE SEMINAR | BRUSSELS |19.03.14 buildings, networks and open spaces BUILDING MATERIALS WORK SECTIONS BUILDING ELEMENTS BUILDINGS NEIGHBOURHOODS
  8. 8. 8 DAMIEN TRIGAUX | DS²BE SEMINAR | BRUSSELS |19.03.14 [RESULTS] ENVIRONMENTAL PROFILE OF AN ASPHALT ROAD FOR LOCAL TRAFFIC § Low environmental impact of base and sub-­‐base: recycled materials (crushed rubble) § High contribuDon of asphalt layers: impact of producDon and replacement (scenarios) [Trigaux, D., Allacker, K., De Troyer, F., Model for the environmental impact assessment of neighbourhoods, accepted paper Environmental impact 2014 Conference -­‐ Ancona]
  9. 9. 9 DAMIEN TRIGAUX | DS²BE SEMINAR | BRUSSELS |19.03.14 [RESULTS] ANALYSIS OF ABSTRACT NEIGHBOURHOOD MODELS § Important impact differences between the dwelling typologies (different amount of infrastructure, building elements and heat losses per floor area) § Limited contribuDon of road infrastructure, compared to the impact of buildings [Trigaux, D., Allacker, K., De Troyer, F., Model for the environmental impact assessment of neighbourhoods, accepted paper Environmental impact 2014 Conference -­‐ Ancona]
  10. 10. 10 [CONCLUSIONS] RECOMMENDATIONS § Extension of the element method for cost control DAMIEN TRIGAUX | DS²BE SEMINAR | BRUSSELS |19.03.14 to the neighbourhood scale § Extension to other infrastructural components (e.g. bicycle and foot paths, electricity and water networks, sewerage and district heaDng) § Detailed analysis of the maintenance and replacement scenarios of the road surfacing layers § Importance of neighbourhood layouts and building typologies (compared to the opDmisaDon of a specific process such as operaDonal energy) [Trigaux, D., Allacker, K., De Troyer, F., Model for the environmental impact assessment of neighbourhoods, accepted paper Environmental impact 2014 Conference -­‐ Ancona]
  11. 11. 11 [CONCLUSIONS] OPEN ISSUES § LCA tool DAMIEN TRIGAUX adapted to the architectural pracJce: | DS²BE SEMINAR | BRUSSELS |19.03.14 different target groups and design stages § EsDmaDon of the energy consumpJon, based on the layout and geometry of buildings and all possible interacDons (solar shading) § Impact assessment of commuter transport, based on locaDon and transport faciliDes § Impact assessment of building land use and ecological systems (e.g. municipal parks and green roofs) § EvaluaDon of society related qualiJes (e.g. socio-­‐cultural values, process qualiDes and diversity)
