IBO - Environmental and Health related Criteria for Buildings Detailed information of neighbours and the public in general (including contact points for complaints) are reserved to large-scale building sites in the current version of TQB, but will probably be integrated for “average” building sites in future versions. 10.7. Summary and Conclusions – Construction Site Management Summary Construction sites are responsible for various impacts, especially at a local level. These arise from disturbance (noise, dust, etc.), pollution and waste. The weighting of construction site related issues is usually marginal (at about 3% of all achievable credits) 97 compared to criteria assessing the use stage of the building. Nevertheless, they illustrate a phase within the building’s lifecycle in which social impacts are extended to neighbourhood and workers at the building site. The analysed building assessment systems refer to similar impacts caused by building site activities (construction waste, noise, dust, environmental impacts to soil, water), but use different indicators for rating. Ratings differ in scope and subject of assessment, extent of impact and groups affected by the considered impact. Example “dust”: Dust avoidance in DGNB primarily refers to working conditions and handling of construction machines generating dust (main target group: operatives). TQB considers dust prevention measures primarily in order to avoid disturbance of neighbours, although workers benefit as well from dust attenuation at the building site (e.g. interdiction of free storage of sand and debris; grave or paved building streets; wetting of waste during reloading, etc.). Apart from CSH and DGNB, working conditions during construction are not part of assessment systems of buildings. CSH, the Code for Sustainable Homes offers the most comprehensive evaluation for construction sites using an established third-party certification scheme of the construction industry (“Considerate Constructors”) to detect and assess all relevant impacts of construction site activities including operational safety and health protection measures and cleanliness of site as well as information policy and a code of behaviour for operatives. Besides this certification scheme, CSH additionally awards the ecological value of site and its conservation, monitoring of energy and water consumption of building site activities and responsibly resourcing of construction timber. Third Draft for EU Ecolabel mainly relies on process-related criteria. It asks for certification of constructors (e.g. QMS, EMS) and approved experience of designers in ensuring quality of planning and construction. CSH, the Code for Sustainable Homes as well as all BREEAM (based) schemes refer to QMS and EMS by assessing the production process of materials, but not construction site activities. DGNB also includes several process-related assessment criteria (such as integration of sustainability requirements in tender guidelines, quality of design process, quality of 97 CSH, TQB, LEED for Homes Final Report 122 31 03 2011
IBO - Environmental and Health related Criteria for Buildings constructors, quality assurance of construction, integrated design process) which do not include target values to achieve, but processes to pass. LEED for Homes mainly focuses on construction waste management and protection measures for soil to guarantee prospective planting and landscaping. Reduction, diversion, re-use, recycling of construction site waste is assessed in almost all systems (apart from SBTool applicable for small residential buildings where the waste arising in the construction phase is neglected). Energy and water use are minor impacts in relation to the overall impacts of the building and therefore usually not assessed (CSH requires setting targets for site-related energy and water consumption and monitoring measures for verification). Emissions resulting from transports to and from site are usually not directly assessed, but taken into account by the requirement for regional materials and products. Reduction of the building site traffic by avoidance of unloaded trips (from the site) and by higher usage of trains or waterways (if applicable) is only assessed within TQB (for more information to traffic-related issues; see also chapter “Energy and CO 2 Emissions).
