Waste reduction final report -4 - Test Input

est outcome. This includes applying life cycle assessment across each stage of the
dismantling and recycling (or disposal) process).
Promotion of dismantlement of specific building materials and recycling
A greater understanding of the costs and benefits relating to the dismantlement and recycling
of specific building material wastes should be developed. Everyone in the supply chain
should co-operate to achieve the best outcome. The Government should provide web-based
resources relating to guidance and location of suitable recycling facilities.
Hazardous materials
Hazardous wastes must be dealt with correctly, in line with existing legislation such as Waste
Disposal Act, Clean Air Act, Act on Special Measures against Dioxins, Occupational Safety
and Hygiene Act. In particular, measures to prevent CFCs or asbestos from escaping into the
environment need to be implemented. Guideline includes specific guidance on the incidence
and control of CFCs in refrigeration applications (considered too difficult to retrieve from
insulation), asbestos, and wood treated with CCA.
3. Guidance documents and tools
CASBEE
CASBEE (Comprehensive Assessment System for Building Environment Efficiency) is an
environmental labelling method for buildings. BEE (Building Environmental Efficiency) was
developed as a new indicator. The environmental performance of the building is labelled as
B-, B+, A and S. The assessment categories of CASBEE are “Quality of Building” and
“Environmental Load”. “Quality of Building” includes “Indoor Environment”, “Quality of
Service” and “Outdoor Environment on Site”. “Environmental Load” includes “Energy”,
“Resources and Materials” and “Off-site Environment”. BEE is calculated by dividing
“Quality of Building” with Environmental Load”.
The sub categories relating to “Resources and Materials” in CASBEE are “Water Resource”
and “Material of Low Environmental Load”. “Material of Low Environmental Load” has sub
categories of “Recycled Materials”, “Timber from Sustainable Forestry”, “Materials with
Low Health Risks”, “Reuse of Existing Building”, “Reusability of Components & Materials”
and “Use of CFCs & Halons”. See Figure 8 for indicative results.
BEAT
BEAT (Building Environment Assessment Tool) is a life cycle assessment system that
calculates environmental impacts related with homes and offices. BEAT is a tool to help
designers of buildings to decrease environmental impacts, to be used by ordinary building
designers who are not familiar with life cycle assessment and environmental effects of
buildings.
BEAT considers the entire life cycle of houses and office buildings. The life cycle of building
is divided into five stages, production and transport of building materials and components,
assembling on construction site, using or living in the building, renewal and renovation, and
demolition. The results displaying window of BEAT-HOUSE is shown in figure 7. BEAT
was developed by the Building Research Institute and the National Institute for Land
Infrastructure Management.
