GBTool V 1.81
This is a tool for researchers involved in the Green Building Challenge (GBC)
process, and is not intended for direct application by end users. However, members
GBT 2k2 V1.81 of national GBC teams are free to convert the tool into a system for end users. Such
conversion will involve establishing or adjusting the default weights, assessment
July 2002 criteria, emission and cost criteria to be relevant to local conditions. Persons testing or
using this system are urged to submit their comments to the GBC Secretariat so that
we may improve the system in the future.
GBTool is intended to be used for the assessment of potential energy and environmental
performance of buildings. The GBC process is managed by iiSBE, the International Initiative for a
Sustainable Built Environment .
GBTool provides approximate assessments of a broad range of potential environmental performance
parameters, all related to performance benchmarks that are relevant to the region and building
occupancy. Although GBTool performs various internal calculations, it is primarily designed to act as a
framework for scoring and weighting, using data generated in external models to perform detailed
studies.
In GBTool, scores are assigned in a range of -2 to +5, where:
- 2 and -1 are levels of performance below the acceptable level in your region, for occupancies specified;
0 is the minimum level of acceptable performance in your region for occupancies specified;
3 is Best Practise; and
5 is the best technically achievable, without consideration of cost.
The 0 or Benchmark values are assigned in the Bmark worksheet, plus a few +5 Benchmark (or "Best")
values for energy performance.
The performance scores for the Design are assigned in the Assess worksheet.
There are four levels of parameters included in the system, including in descending order of generality,
Issues, Categories, Criteria and Sub-Criteria. The Issues and Category parameters are voted on by team
members in the Vote worksheet, but the two lowest levels are assigned automatically (see the Weight
worksheet). Scores are multiplied by the weights and the weighted scores are shown in the Results
worksheet.
GBTool can handle both new building and renovation projects. Please note that, in the re-use of an
existing structure to serve as part or all of a new building, the description of the new building in the Area
worksheet (floors, areas, volumes etc.), includes the existing re-used structure in Block 1. However, the
other worksheets which describe the Design (Arch, Tech, Matrl) treats old and new in an integrated way.
Features and
comments
Features and
comments
GBTool looks pretty scary at first glance, mainly because we have built in many options (up to 4 blocks,
up to 4 occupancies etc.) If you want to hide some of the things you don't need, go to the Views
menu, then to the Custom Views sub-menu, and pick a more manageable version. In doing this,
the data do not disappear, but are only hidden. To see everything, use the "All shown" option. Note that
printing formats are based on the "All shown" setting, and result in 103 pages. Printing the
Benchmarking option only results in 27 pg., the Assessment option results in 52 pg., and the Designer 2
blocks and 3 occupancies requires 49 pg. of printout.
GBTool is implemented in Excel 2000, but on our site (http://iisbe.org) you will also find an Excel 97
version. In preparing the Excel 97 version, an error message was generated, stating that one error was
generated in the conversion, but the message did not specify which cell was affected. This is probably
not a major issue. As you move from one level of detail to another in the Assess worksheet, you will also
come across an error message stating that a formula contains an invalid reference to an external
worksheet. Despite a standing offer (since 1997) of a prize, nobody has been able to identify the source
of this spurious message.

ID occupancy types in the building (up to four).
The following worksheets should be completed by a team that does NOT include persons who are linked to the design or
persons who are undertaking the assessment.
Cntxt (Context) is meant to characterize the micro-urban neighbourhood so that assessors have an
understanding of relevant local issues. This information is needed to establish meaningful weights and may
also inform the establishment of benchmarks. For example, an area that is characterized in C30 or C31 as
Cntxt having a shortage of water may lead the assessor to set a low benchmark for water consumption (see Bmark
B80-B91)
The Vote worksheet allows GBC teams to set the weights that are appropriate for their regions for the two top
levels of parameters used in GBTool: Issues and Categories. Our approach to setting weights makes a clear
distinction between the very general Issue areas and the more specific Categories. GBC takes the position
that Issue areas are so broad as to be inherently subjective; whereas more objective means, such as national
data, may be used to establish Categories within each Issue area. GBTool therefore provides defaults for
Issues, but allows teams to change these and to indicate what basis they used for their decision.
Vote For Categories, up to 12 persons may enter votes, which are then averaged and sent to the Weight
worksheet. The basis for voting should be related to appropriate skills; e.g., the Categories for Indoor
Environmental Quality should be voted on by persons having extensive knowledge in these areas. Mauritz
Glaumann of Sweden is developing a more rational basis for assigning weights which may be adopted in the
next version.
This worksheet provides users with tables to enter emission values for fuels and electricity production relevant
Engen to their regions. The results, based on fuel mixes for base loads, are used to determine emissions due to
energy consumption, which are shown in the Report worksheet.
The Bmark worksheet is designed to allow the entry of benchmark performance values that are appropriate to
the region and occupancy types included in the building. Benchmarks in GBTool are the basis for assigning
scores for performance of the Design, so they are of considerable importance. In GBTool, benchmarks are set
as the minimum acceptable industry norm or regulation that is applicable. In some case this is easy, because
Bmark a regulation exists; but in other cases a panel may have to be assembled to develop a benchmark. In all
cases, the intent is to provide a meaningful comparison for performance values of the Design.
20 River Terrace, Battery Park City, V1, New York City, USA, Introduction
The following worksheets are intended to be completed by a team of persons who are knowledgeable about the design.
Data on number of stories, functional area requirements, gross areas, net areas, wall areas and glazing area
and characteristics are entered in this worksheet. These data are used for many subsequent calculations in
other worksheets and must be completed. A specific example is the relative areas of various occupancy
Area types, which influence several weights at the Criterion and Sub-Criterion level in the Weight worksheet. Note
that the worksheet allows for up to four separate blocks to be designated, which is useful in the case of larger
building complexes.
The Archworksheet permits user entry of the basic occupancies in the building, as well as descriptions of a
number of other architectural features and elements. Up to four occupancies can be specified in a single
project. Multi-unit Residential is designated as either being present or absent, and up to three other
Arch occupancy types can then be specified freely by the user. The specific occupancies specified then become
headings for data entry in the Bmark worksheet.
The Techworksheet provides space for the characterization of technical systems in the building, including
Tech HVAC, lighting and control systems. It also provides entries for energy consumption.
The Matl (Material) worksheet provides a table to capture weight and volume data on some major groups of
Matrl materials. It also allows estimates to be made of the percentage of these material groups that conform to
various environmental requirements.
The Ops worksheet is intended to describe various features related to the future operation and management
Ops of the building.
The LCC (Life-cycle Costing)worksheet is only partially complete. The intent is to provide a full basis for the
LCC calculation of life-cycle costing, but data on replacement materials and components is not yet available. As it
stands, the worksheet provides a crude indication of life-cycle cost.
The Trrnsprt (Tansport) sheet is under development. When complete, it will provide inputs and algorithms to
Trnsprt allow a crude estimate to be made of the commuting transport that is likely to be generated by the building.
The Assess worksheet is intended to be completed by a team of persons who have reviewed all other worksheets and who
The Assess worksheet is intended to be completed by a team of persons who have reviewed all other worksheets and who
have the skills required to assess various specialized aspects of building performance, but who are ot associated with the
Design. The other worksheets (Rprt, Weight and Result) require no user input.
Rprt (Report) provides users with a summary report on a variety of building characteristics and performance
Rprt data. Note that many results are normalized by occupancy. There are no user-modifiable fields.
The Weight worksheet is one of the key worksheets in the system. Weighting values for Issues and
Categories are transferred from the Vote worksheet, and weights for Criteria and Sub-criteria are also shown.
Except for some comment spaces, there are no user-modifiable fields in this worksheet. Many of the weights
Weight for Criteria and Sub-criteria are developed through the use of formulae that take into account relative areas of
occupancies or mechanically-cooled space. Others are determined by total building size or presence of
Radon, ambient noise characteristics etc. All are annotated.
This is the key worksheet in the whole system. It contains scoring fields for all parameters in the system, and
then weights these scores according to the weights assigned in the Vote and Weight worksheets. Some are
calculated automatically and are shown in grey. The yellow scoring boxes require the intervention of team
members to pass judgement, since they are not amenable to calculation. Enough information should be
Assess available in the Context, Arch and Tech worksheets to be able to assign a meaningful score. It should be
noted that any parameters that have been weighted at 0 do not require a score to be assigned. Also note that
the worksheet can be viewed at any of four levels of detail (boxes at upper left hand corner)
The final worksheet in the series shows results of the assessments made, via scores and weights. There are
two types of results shown: Environmental Sustainability Indicators (ESI), which are absolute numbers; and
Result barcharts that show weighted scores (-2 to +5) relative to the benchmarks (0).
