JV3 Modelling Tools
JV3 modelling is like NatHERS modelling, yet with far more capabilities. The software used for the JV3 alternative method or the energy Performance Solution should be capable of hourly energy modelling of a building and should comply with the ABCB’s set of regulations.
At Energy Compliance we model buildings with DesignBuilder modelling software. This robust energy modelling software complies with all the requirements in NCC energy Performance Solution clauses. For commercial buildings, it complies with the ABCB Protocol for Building Energy Analysis Software (Version 2006.1). Referring to Clause 3 of the ABCB protocol for building energy analysis software; DesignBuilder software:
Is commercially available in Australia;
Is based on a simulation program using an hourly climate data file;
Is capable of computing the annual energy consumption of a building under the Verification methods of the NCC;
Can geometrically describe the building in 3D, which accounts for the surface azimuth, tilt angles and adjacent structures and features;
Provides the results comparable to other similar software under ASHRAE Standard 140, Standard Method of Test for the Evaluation of Building Energy Analysis Computer programs using International Energy Agency BESTEST,
Satisfies all the specific capabilities in Clause 4 of the ABCB protocol for building energy analysis software.
Has a calculation method that complies with ANSI/ASHRAE Standard 140 and can assess the heating load and cooling load by modelling:
(i) The building fabric; and
(ii) Glazing and shading; and
(iii) Air infiltration and ventilation; and
(iv) The function and use of the building, including zoning, hours of occupation, hours of heating and cooling availability and internal heat gains; and
(v) Relevant built-environment and topographical features; and
(vi) The sensible heat component of the cooling load and heating load.
DesignBuilder can use climatic data in the calculation that is based on hourly recorded values and represents a typical year for the proposed location.
