Energy efficiency in commercial buildings and establishments is extremely important. Green buildings can minimise power costs, reduce greenhouse gas emissions and aids in projecting an eco-friendly image for both owners and tenants.
However, it’s not the customer demand alone driving sustainable constructions and energy-efficient buildings.
Certain regulatory requirements ensure that Australian commercial buildings are designed and built to meet appropriate environmental standards. A BCA Section J Report is one such regulatory requirement.
What is a BCA Section J Report?
As a component of NCC, the Australian Government has determined a set of regulatory requirements to make sure that commercial buildings adhere to a basic level of energy efficiency and sustainability.
Section J of the NCC mandates construction companies to furnish evidence that the construction has fulfilled the energy efficiency criteria for Class 3-9 buildings (and, in certain cases, common areas of Class 2 buildings).
These constructions include commercial, residential buildings, apartment buildings, office establishments, retail buildings, schools, hospitals, industrial establishments, public buildings like car parking establishments, etc.
The main objective of a BCA Section J Report is to make sure that the design, built materials, and construction of these buildings fulfil the energy efficiency standards outlined in Section J of the NCC.
The report aims to ensure all Class 3-9 buildings reduce greenhouse gas emissions through lesser energy consumption, promotion of energy-efficient systems and facilitation of passive heating/cooling techniques.
When is a BCA Section J Report Required?
A BCA Section J Report is required before the construction of all class 3-9 commercial buildings. The report is also necessary for building extensions and refurbishments.
It is generally required when you apply for a development application or construction certificate application.
Ideally, the report should be completed during the project’s design phase to rectify any non-compliant design elements. This eliminates the hassle and cost of reordering raw materials to make changes to an already underway construction.
Who Performs a BCA Section J Report?
BCA Section J Reports are conducted by qualified energy efficiency consultants. Consultants must have adequate knowledge of the relevant energy efficiency measures for major mechanical and electrical systems of a building and the thermal properties of building fabrics and insulating materials.
What does the BCA Section J Report Entail?
Section J compliance assessment is performed against the following categories-
J1: Building Fabric
J2: Glazing – includes shading
J3: Building Sealing
J4: Air Movement Facilities and Provisions
J5: Air-conditioning and Ventilation Systems
J6: Artificial Lighting and Power Supply
J7: Hot Water Supply, Swimming Pool and Spa Pool Plant
J8: Access for Maintenance and Monitoring Facilities
Once all aspects of the design get assessed by a qualified energy efficiency consultant, the building can be issued with an approved BCA Section J Report.
