L (Loadings): Building Environmental Loadings
Evaluates ‘negative aspects of environmental impact which go beyond the hypothetical enclosed
space to the outside (the public property)’.
By relating these two factors, CASBEE results are presented as a measure of eco-effi ciency or
BEE (Building Environmental Effi ciency). Results are plotted on a graph, with environmental load
on one axis and quality on the other – the best buildings will fall in the section representing lowest
environmental load and highest quality. Each criterion is scored from level 1 to level 5, with level 1
defi ned as meeting minimum requirements, level 3 defi ned as meeting typical technical and social
levels at the time of the assessment, and level 5 representing a high level of achievement.
CASBEE major categories of criteria include
Building Environmental Quality and Performance
# Indoor environment (noise and acoustics, thermal and visual comfort, and indoor air quality)
# Quality of services (functionality and usability, amenities, durability and reliability, fl exibility and
adaptability)
# Outdoor environment on site (preservation and creation of biotope, townscape and landscape,
local characteristic and outdoor amenities)
Building Environmental Loadings
# Energy (Building thermal load, utilization of natural energy, effi ciency in building service systems,
and effi cient operations)
# Resources and materials (water conservation, materials of low environmental loads)
# Off -site environment (air pollution, noise and vibration, odour, sunlight obstruction, light
pollution, heat island eff ect, and load on local infrastructure)
1. 2.3 GBTool
GBTool was developed by the International Framework Committee for the Green Building Challenge,
an international project that has involved more than 25 countries since 1998. GBTool is designed to
be adapted by sponsors to refl ect regional conditions and context. It includes criteria in categories
such as Site Selection, Project Planning and Development; Environmental Loadings; Energy and
Resource Consumption; Indoor Environmental Quality; Functionality; Long-Term Performance; and
Social and Economic Aspects. Criteria are assessed using scales that are based on local benchmarks
of ‘typical’ practice; buildings can score –1 if below typical practice or from +1 to +5, representing
good to very high performance. All criteria must be attempted. The benchmarks of typical practice
and weightings of criteria are set by the sponsoring organization to represent national, regional, or
local codes, practice, context, conditions, and priorities.
GBTool major categories of criteria include the following.
# Energy consumption is assessed through total use of non-renewable energy (embodied and
operational), electrical demand, usage of renewable energy, and commissioning.
# Resource consumption is assessed through materials use (salvaged, recycled, bio-based and
sustainably harvested, locally produced, designed for disassembly, re-use, or recycling) and
water use for irrigation, building systems, and occupant use.
# Environmental loadings include GHG emissions, other atmospheric emissions, solid wastes,
storm water, waste water, site impacts, and other local and regional impacts.
