EQUIREMENTS
The computer simulation requirements shall be referred to Section A2 -
Numerical Method for Building Energy Analysis in BEC.
Clause A2.1 in BEC states: The numerical method for the building
energy analysis shall be targeted for the estimation of energy
consumption in buildings in a comprehensive manner and shall include
calculation methodologies for the building components or systems being
considered.
The required numerical method shall include but not limit to the following
features:-
The use of a computer-based hour-by-hour, full-year, multiple-
zone numerical analysis for modelling and simulating the design
energy and energy budget is required.
The simulation program shall be capable of modeling and
simulating the thermal behaviour of a building and the interaction
of its building fabric, air-conditioning, lighting and other relevant
energy consuming equipment and systems.
The simulation program shall be capable of performing design
load calculations to determine the required air-conditioning
equipment capacities and air and water flow rates for both the
designed building and reference building.
The simulation program shall be able to deliver the following
printouts:-
(a) breakdown of energy consumption for lighting installation,
space cooling and heat rejection equipment, space heating
(if provided), fans of AHUs and ventilation fans, pumps for
