  1. A concept for environmental management of chemicals in the building process The Royal Institute of Technology University of Gävle, HIG Beatrice Kindembe, PhD student1, Mauritz Glaumann, Dr Eng2 1Department of Urban Planning and Environment, Division of Built Environment Analysis Unit, KTH, S-10044 Stockholm, Sweden 2 Department of Technology and Built Environment, HIG, S-801 76 Gävle, Sweden

  2. Background • EcoEffect, a tool for environmental assessment of buildings • The internal impacts, the assessment of the risk for discomfort and ill-being due to the indoor and outdoor environment within the boundary of the building property. • The external impacts of manufacturing and transport of the building materials and the production of power and heating consumed during the operation phase. Waste and natural resource depletion. • Knowledge of content in and possible release of hazardous substances from the building materials is scarce and these aspects have often been neglected in environment assessment tool • Only well-known hazardous substances such as PCB, heavy metals Pb, Cd, Hg, As are inventoried in old building when planning demolition to provide a coherent waste management. The aimTo design a coherent concept for environmental management of chemicals providing data on hazardous chemicals in buildings

  3. Method • A survey of the building sector environmental management strategy related to chemicals • Document study, 33 companies (real estate companies and organizations, constructors and building consultants) • Goals • Questionnaire to 8 real estate companies • the implementation of the strategy • chemicals related environmental information/storage of building data. • Case study, 2 building projects • the implementation of the environmental management strategy and documentation routines in the building process

  4. Studied building projects

  5. (II) Implementation of the management strategy during the building process

  6. (III) Stored data based on the building owner’s requirements

  7. Chemicals substances, 31 Jan 2000 Vinyl chloride polymer CAS-nr 9002-86-2: 1,52 kg/m2 DEHP CAS-nr 117-81-7: 0,57 kg/m2 Calcium carbonate, aluminium silicate, calcium magnesium carbonate. 0,75 kg/m2 Titanium dioxide, etc: 0,06 kg/m2 Ca-Zn compound, etc: <0,05 kg/m2 Surface compounds, polyurethane: < 0,03 kg/m2 Chemicals substances, 06 Dec 2000 1,52 kg/m2 Diisononyl phthalate (DINP) CAS-nr 28553-12-0: 0,54 kg/m2 0,75 kg/m2 <0,05 kg/m2 < 0,02 kg/m2 Environmental declaration of a floor carpet

  8. The concept

  9. Chemical data, flooring products

  10. Chemical profile - based on chemical content of products

  11. Chemical profile - based on the built-in chemicals

  12. Conclusion • The building owners can influence the nature of data on buildings regarding built-in materials and chemicals earlier during the building process. • To trace chemicals in building, the difference should be remained between used chemicals and built-in chemicals mostly regarding chemical products. Chemicals of concern for the work environment during the construction phase may not be of concern for the Indoor Air Environment and the demolition waste in the future. • Specific tools based on Life Cycle Assessment (LCA) approach have been developed to assess environmental impacts of buildings. Often effect categories such as global warming potential, acidification, eutrophication, photochemical ozone creation potentials are calculated based on the occurred emissions during the production of the energy and manufacture of used building materials. Hazardous substances and possible emissions from building materials have often been neglected in LCA because of the lack of data. • A key issue to increase the knowledge of chemicals in buildings is to create a structure for conveying information from the product manufacturer to the building tenants. The first step in this process should consist to document chemicals used during the construction process and register their amounts.

  13. Mentoring • Inspire to higher education • Explain how the University/Institution/Department/Company works • Spends time talking with and listening to • Introduce to our world - new people/network, places, interests, or ideas • Coach to reinforce positive behavior and encourage ambitions • Share personal experience relevant to the needs of the youth • Share the experience of having double identities –African-Swedish

  14. Target group: Secondary school’s pupils 13-16 years/Before the Upper Secondary School choice Channels: Schools African Diaspora organizations/families Procedure: Introduction of Nawes, resource group Matching of Nawes members and the pupils depending on the pupil’s needs. Ongoing dialogue with the school of Hjulsta, Stockholm Coming activities • Meeting with the the counsellor, Hjulsta skolan • Visit and Nawes introduction to Hjulsta school • Information to the parents • Parent’s agreements • Meeting, school-parents-pupils • Mentors – mentees
