Rating System Using checklist or forms

GBTool (Green Building Tool)
4
BREEAM (Building Research Establishment
Environmental Assessment Method)

• BREEAM is a tool that allows the owners, users
  and designers of buildings to
• review and improve environmental
  performance throughout the life of a building.
• Assessment is based on credits awarded for a
  set of performance criteria.

5
Green Globes

• Green Globes is an online building and
  management audit tool.
• It is web-enabled self-assessment based on
  BREEAM/Green Leaf.
• It uses a confidential questionnaire, and
  generates an online report.
• It is the newest addition to the BREEAM/Green
  Leaf suite of environmental assessment tools.
• It is intended for property manager and owners
  of commercial and multi-residential buildings.

LEED Rating System
Self-assessing system requiring documentation
Focuses on five environmental disciplines
Offers four levels of certification Intended
for the U. S. Market

7
NABERS (National Australian Buildings
Environmental Rating System)

• NABERS was designed to rate the environmental
  impact of buildings (commercial residential).
• This rating system will be structured to have a
  series of headings, with "scores (1 5 stars)"
  chosen as the unit
• of measurement.

8
CASBEE (Comparative Assessment System for
Building Environmental Efficiency)
CASBEE is designed for use along with the
building design processes, beginning with the
Pre-design phase, and followed by the Design
and Post-design phases. CASBEE comprises a
variety of assessment tools (Pre-design
assessment tool, DfE tool, Eco- labelling tool
and Sustainable operation renovation tool).
CASBEE covers the four assessment aspects
9
Ecoprofile
Norwegian LCA based computer tool which
calculates the environmental effects during the
life cycle of building Ecoprofile is divided into
three principal components.
10
ENVEST

• Envest is the software tool developed by UK for
  estimating the life cycle environmental impacts
  of
• a building from the early design stage.
• The first version is for office buildings and
  considers environmental impacts of both
• - materials used during construction and
• - the energy and resources consumed over a
  building life.
• Envest identifies the elements with the most
  influence on the buildings environmental impact

11
ATHENA

• Athena is a LCA-based environmental decision
  support tool for building materials and buildings
• Athena helps designers achieve the best
  environmental footprint by showing the five
• separate conceptual designs.
• Easy-to-use decision support tool
• Only North American software for LCA of buildings

12
ECOQUANTUM

• LCA based computer tool which calculates the
  environmental effects during the entire life
  cycle of the building
• This includes the impact of energy, the
  maintenance during the use phase and the
  differences in the durability of parts of the
  construction related to the life span of the
  building
• Eco-Quantum also takes into account the
  possibility for selective demolition, recycling
  and product reuse.

13
BEAT (Building Environmental Assessment Tool)

• BEAT is an LCA-based life cycle inventory tool
  for building products/building elements/buildings
• BEAT is based on the Danish life cycle
  assessment method EDIP (Environmental Design of
  Industrial Products)
• BEAT is a relation database designed using
  Microsoft Access
• The database contains data for most conventional
  primary building products
• used n the Danish building industry (cement,
  concrete, gypsum boards etc.) commonly used
  building elements.
• It also contains a number of energy sources and
  means of transport.

14
GreenCalc

• GreenCalc is a computer tool to calculate the
  environmental load of a Dutch office building.
• It is divided into four modules materials,
  energy, water usage and mobility.
• - Material module choice of materials,
  quantities, insulating values
• - Energy module energy consumption in the
  operation phase (use of building,
  air-conditioning, ventilation, lighting.)
• - Water usage water consumption in the
  operation phase (facilities, sanitary facilities,
  rainwater etc.)
• - Mobility accessibility from home to work
  place (location, public transport, own transport)
• Results are expressed in terms of money as
  so-called submerged environmental costs (cost per
  m2)
• (Total score on a scale from 1 - 2000. The
  average building built in 1990 has a score of 100
• and the goal for 2050 is buildings with a
  score of 2000)

15
BEES (Building for Environmental and Economic
Sustainability)
Develop and implement a systematic methodology
for selecting environmentally and economically
balanced building products.
16
LCAid

• Computer software developed by NSW Department of
  Public Works and Services (DPWS)
• User friendly decision making tool using LCA
  methodology to evaluate
• -to evaluate the environmental
  performance of design options, and
• -to identify the largest impacts over
  the entire life cycle of a building.
