IBO - Environmental and Health related Criteria for Buildings 10. CONSTRUCTION SITE MANAGEMENT The following examination will focus on environmental as well as health-related aspects of construction site activities and their implementation in the analysed assessment systems EU Ecolabel (3 rd draft), SBTool, CSH (Code for Sustainable Homes), LEED for Homes, DGNB, and TQB. The main topics are construction waste management, noise and dust attenuation, social responsibility with respect to all groups affected by construction site activities (including health protection and safety measures and avoidance of accidents, etc.).Transports to and from site and the related emissions to air are dealt with in chapter “Energy and CO 2 - emissions” 67 . 10.1. EU Ecolabel (3rd draft) (Construction) Waste Management The main focus of waste management strategies within the Third Draft of EU Ecolabel lies explicitly on the operation and demolition of the building. Construction-site related waste is only considered within the optional Section B which means that measures undertaken to reduce construction waste may contribute to achieve the EU Ecolabel, but are not obligatory. Mandatory waste management criteria are only referring to the use stage (Crit 16) and to the demolition stage of the building. Waste management strategies referring to the construction phase are optional criteria. To gain 3 additional points within category “Planning – Project – Construction” it is required that “at least 75% of construction and demolition wastes generated during the construction phase shall be reused or recycled”. Verification refers to the waste management plan and relative documentation showing compliance with the criterion. In order to be awarded with the EU Ecolabel, the building must score a minimum of 6 points for optional criteria within the sub-sections “Documentation”, “Planning-Project-Construction” and “Impact on site issues”. Compliance is demonstrated by process-related assessments (concerning waste management during construction as well as other design and construction topics), e.g. - experience of the designers with environmental building design (32.) in terms of energy and water efficiency, waste reduction, etc.. At least two relevant projects carried out in the last five years are required for verification. (2 points) - QMS (33.): “Companies in charge of the construction of the building shall have a Quality Management System according to the ISO 9001 standard.” (2 points) - EMS (35.): “Companies in charge of the construction of the building shall have an Environmental Management System according to EMAS regulation (2 points) or ISO 14001 standard (1 point)” 67 Transport of materials and products from factory gate to the building site including intermediate storage and distribution are taken into account. Transport of construction equipment (cranes,…) to and from site are not considered. Final Report 104 31 03 2011
IBO - Environmental and Health related Criteria for Buildings - In Crit. 34 an LCA-calculation for the building according to the ISO14040 standard or to prEN 15978 is required, without setting any benchmarks or optimisation steps. Social responsibility (loadings on neigbourhood,…) “Social responsibility during the construction phase” (criterion 5) is defined as mandatory in the Third Draft of EU Ecolabel, but not yet specified. It refers to prEN 15643-3:2010 68 where loadings from construction site activities are not yet taken into account. Annex B gives an outlook on criteria for the construction stage to be dealt with in future standardisation work: It is intended to develop assessment criteria evaluating the impacts on neighbourhood (from traffic and noise) and to develop social standards of construction process (safety, neighbourhood protection). Society-related issues shall comprise - Social standards of companies involved (CSR – Corporate Social Responsibility standards and reporting) - Social facilities on construction site (toilets, kitchen, etc.) Health and safety aspects related to construction workers are definitely excluded from the first generation of standards. As the current version is restricted to the use stage and awaits further development, assessment criteria for construction site activities cannot be derived for the EU Ecolabel from this draft standard. Besides, “levels, classes or benchmarks for measuring performance” will generally not be dealt within this standard. 10.2. SBTool (Construction) Waste Management Waste-relevant issues occur in the following sub-categories: A.2. Project Planning A.2.7. Collection and recycling of solid wastes in the community or project B.4. Materials Resid. Mixed use • B.4.4. Use of durable products • • B.4.10 Design for disassembly, re-use or recycling • C.3. Solid Waste C.3.1. Solid waste resulting from the construction and demolition process • C.3.2. Solid waste resulting from facility operations • • For (small) residential buildings, waste reduction is assessed only by two indicators both reflecting the use stage of the building. 68 prEN 15643-3:2010: Sustainability of Construction Works - Assessment of Buildings - Part 3: Framework for the assessment of social performance Final Report 105 31 03 2011
