Market Acceptance
For a voluntary scheme the extent to which performance can be
enhanced is determined by market acceptance of the assessment
criteria, BEAM’s track record, and the cost of undertaking assessment.
Judging from the number of projects certified the performance criteria
included in the various versions of BEAM have been both realistic and
attainable in practice.

RINCIPLES
According to international consensus [4, 6] building assessments should
be performance based as far as possible. Assessment needs to take a
holistic view of performance with the emphasis on life-cycle impacts.
Assessment purely on prescriptive features would preclude areas
without those features from obtaining a good result regardless of their
actual performance. Furthermore, assessments based on features
would only encourage feature-based design, construction and operating
practices.
Transparency
BEAM Plus recognises that assessment criteria and methods to achieve
compliance need to be transparent, providing details of the benchmarks
(baselines), data, assumptions and issues taken into account in the
assessments and the rating.
BEAM Plus Interiors, a first for BEAM, conducted an open, three month
consultation period (April-July 2013) when stakeholders, members of the
public, and professionals submitted comments.
Flexible and Objective
BEAM Plus embraces a wide range of projects, variable in terms of
scale, location and mix of uses (types of premises). The assessment
criteria and methods of assessment need to be flexible, and have
alternative means of compliance, yet are reasonably objective to enable
the Assessor to draw conclusions without undue delay or controversy.
Updates to Assessment Criteria
The BEAM Plus rating schemes are revised and updated from time to
time to reflect changes in industry standards and practices, findings from
Credit Interpretation Request, Circular Letters and other related
developments. Updates are issued as addenda to the rating system in
circulation at the time and incorporated into future revisions.
Where the criteria is revised or modified after the project has been
registered, the framework and credits that were current at the time of
registration shall prevail unless the Applicant wishes to embrace the
revisions and updates.
Special Cases
It is possible that some projects may not be fully embraced by the
criteria currently presented in this Manual, whether due to their unusual
nature or variety of forms and system designs, etc. In such
circumstances certain assessment criteria or the method of
demonstrating compliance may need to be modified. This requires
advance agreement between the Applicant and the BSL TRC.
Certification Upon Completion
A key principle of BEAM Plus rating tool, and its predecessors has
always been that certification is issued only upon completion of the
project, this helps to ensure that committed design features are actually
installed, that construction practices have met the required standards,
