In principle, BEAM would accept the use of most of the energy
analysis simulation software listed in the latest edition of EMSD
Performance-Based Building Energy Code.
However, the BSL TRC might review the acceptance of any other
software that are not in the list but embrace those simulation general
requirements as highlighted in latest edition of ANSI/ASHRAE/IES
Standard 90.1. The Applicant shall submit a report to justify its
suitability.
ASHRAE A
PPROACH
ANSI/ASHRAE/IES Standard 90.1-2010 Energy Standard for
Buildings Except Low-Rise Residential Buildings is to provide
minimum requirements for the energy-efficient design of buildings
except low-rise residential buildings. Appendix G of
ANSI/ASHRAE/IES 90.1-2010 provides the alternative approach,
which is intended for use in rating the energy efficiency of building
designs that exceed the requirement of Section 11 of the
ANSI/ASHRAE/IES standard 90.1-2010.
It may be useful for evaluating the performance of all proposed
designs, including alterations and additions to existing buildings,
except designs with no mechanical systems. The detailed
requirement, assumption and modelling methodology for calculating
the proposed and baseline building performance shall be made
reference to the ANSI/ASHRAE/IES Standard.

Where simulation programmes cannot adequately model the design
strategy (for example passive design contributing to reduced CO
2
emissions), material, or device the BSL TRC may approve an
exceptional calculation method to demonstrate above-standard
performance.
The exceptional calculation shall make reference to Section A3.4 of
Code of Practice for Energy Efficiency of Building Services Installation
2012 Edition [3], Appendix G2.5 of ANSI/ASHRAE/IES 90.1 2010 [4],
and Appendix D of the Advanced Energy Modelling for LEED
Technical Manual v1.0 (September 2011 Edition)[5].

PPROACH
Whilst computer simulation is the generic and preferred approach for
predicting annual energy use, the implementation of prescriptive
strategies for reducing the annual energy consumption in th
e project spacecan be used as an alternative to the simulation method.
The prescriptive strategies listed herein, may include the use of high
efficiency equipment, the implementation of energy saving measures,
and the provision of appropriate zoning and controls. Further details of
the rewarded strategies are provided in this Manual.
The Applicant shall submit clearly cross-reference materials including
tables, drawings, technical data sheets, measurements, and the like to
justify compliance.
