If a disclosure affected building or area is undergoing major physical works that will change the NABERS Energy for Offices rating by at least half a star, as assessed by a CBD Accredited Assessor (Assessor), you can apply for an exemption while the refurbishment is underway.
Whether the works will affect the NABERS Energy for offices rating is a judgement for an Assessor to make and justify to the Department of Climate Change, Energy, the Environment and Water (the department) on your behalf, for an exemption to be granted.
Definition of a major refurbishment
A major refurbishment is set out at regulation 5B(1) of the Building Energy Efficiency Disclosure Regulations 2010 (the BEED Regulations). A major refurbishment is one that, according to a Assessor, will alter the NABERS Energy for offices rating of the base building by at least half a star.
This assessment must be based on the NABERS Energy and Water for Offices Rules (the NABERS Rules).
Typically, an office building’s base building energy consumption is driven primarily by HVAC and lighting. Upgrading these systems are common examples of major refurbishments that may change the base building rate by at least half a star.
An exemption on the basis of a ‘major refurbishment’ is in force for 12 months from the day the exemption is granted.
Specific requirements
In addition to the standard requirements, an exemption application on the basis of a ‘major refurbishment’ must include:
- an assessment by a Assessor, showing that the refurbishment is a ‘major refurbishment’; and
- whether the Assessor has complied with subregulation 9(3A) by disclosing any conflict of interest in relation to the application.
Both requirements can be completed by an Assessor through the CBD Assessor Portal.
An exemption may only be granted if the Secretary (or Delegate) is satisfied that a ‘major refurbishment’ of a building (or area) is underway.
Therefore, an exemption application on this basis should include supporting documentation to assist the Secretary (or their Delegate) in being satisfied that the refurbishment of the building is:
- a ‘major refurbishment’ (r 5B(1) of the BEED Regulations); and
- is underway.
Where the Secretary (or their Delegate) is not satisfied that the building is undergoing a major refurbishment, they may request additional information to support the exemption application, which may delay processing.
Supporting documentation
Supporting documentation for major refurbishment exemption applications may include:
-
A brief description of any new equipment or systems installed as part of the project. This can be documented in the CBD Assessor Portal, noting that the contents can be copied from a suitable existing document and does not have to be created specifically for this purpose. For example, this could include information about:
-
central heating, ventilation and air-conditioning (HVAC) system functions or equipment, including controls upgrades;
-
improved energy efficiency of new equipment;
-
addition of variable speed drives (VSDs) or variable frequency drives (VFDs) on motors;
-
vertical transportation system energy consumption;
-
central hot water systems;
-
Any addition of solar photovoltaic (PV) and battery systems.
-
-
Information about any change of use for the building. For example, if the building is being refurbished to upgrade from educational tenants (unrateable) to being suitable for office tenants, this would constitute a change in the NABERS rating.
-
Similarly, if a building was being converted from a warehouse (not office) to a facility suitable for lease as office space. See example around refurbishing a warehouse at Definition of an office.
-
Comparisons between previously installed and proposed equipment efficiencies, if known.
-
Signed contracts for significant components of the major refurbishment project. Note that the major refurbishment project can be deemed to have started if copies of signed contracts of major work elements are provided, even if site work is yet to commence.
-
Works schedule, waterfall diagram or Gantt chart showing a summary of start and finish dates for key elements.
-
Copies of tender, schedule and scope documents or relevant excerpts from contracts to support claims.
-
HVAC contractor documents showing changes to main HVAC systems.
-
Electrical or lighting contractor documents showing changes to base building lighting systems.
-
Solar PV system design documentation including panel layout and estimated output.
-
Photos of the area of the planned works, or of construction work if construction underway.
To be a ‘major refurbishment’, upgrades must alter the base building rating of the building by at least half a star. Upgrades to tenant systems such as tenancy lighting or tenant installed supplementary air-conditioning will not normally reduce base building energy consumption or have an impact on the base building NABERS rating to satisfy this requirement.
When do your disclosure obligations apply?
The stage of the refurbishment project determines when disclosure obligations apply, and whether you can apply for an exemption.
Under the current NABERS Energy and Water for Offices Rules, a building will become eligible for a NABERS Energy for offices rating as soon as 12 months of data can be collected. This is the NABERS Rating Period.
The 12-month NABERS Rating Period can only begin once one of the following requirements is met:
-
75% of the office Net Lettable Area is occupied by tenants, or
-
it has been 2 years since the Certificate of Occupancy (or equivalent) was issued.
Where a refurbished building is not eligible for a NABERS Energy for offices rating, you can seek an exemption on the basis that the building or area is non-assessable. See non-assessable building exemptions for more information.
You will also need to allow time to prepare and process the NABERS Energy for offices rating. NABERS Assessors are allowed up to 4 months after the NABERS Rating Period ends to submit their application.
An exemption may be granted to cover the data collection for the NABERS Rating Period and submission time. The longest exemption is 12 months, but multiple exemptions may be granted if it isn’t yet possible to work out the NABERS Energy for offices rating.
Planning a refurbishment
Before a major refurbishment begins and throughout the planning stage, a building that is disclosure affected remains affected and isn’t eligible for a major refurbishment exemption, as the major refurbishment is not ‘underway’.
In some circumstances, an exemption may be granted for other reasons. For example, an exemption may be granted on the basis that the disclosure affected building or area is non-assessable where a building has been fully vacant for more than 12 months and a NABERS Energy for offices rating can’t be completed.
If you are not granted an exemption, your disclosure obligations will apply. You will need a current registered Building Energy Efficiency Certificate (BEEC) if you offer a disclosure affected building for sale, lease or sublease, and you will need to follow the advertising rules. This applies even when a planned future refurbishment is expected to change the NABERS rating.
A company has accepted a concept plan for a mechanical services upgrade in their office building. The tender documents are being drawn up, but no contracts have been signed for the work.
An Assessor engaged by the company estimates the building’s NABERS Energy for offices rating will increase from 2 stars to 4 stars when the works are complete.
The building is not eligible for a Major Refurbishment exemption because the work is not considered to be underway until the contract is signed.
The company needs a current registered Building Energy Efficiency Certificate (BEEC) or other exemption before it advertises or offers to sell, lease or sublease the building.
Refurbishment is underway
You can apply for an exemption to your CBD Program obligations when the major refurbishment is underway, that is, once the contract for construction or equipment supply have been executed. While a major refurbishment of a building is underway, a building or area that is disclosure affected is still identified as such, even if your exemption is granted.
A company has approved an upgrade to their office’s air-conditioning to achieve a 2-star improvement in the NABERS Energy for offices rating. Contracts have been signed and the first stage of construction work is due to start.
The project is now considered to be underway as contracts have been executed.
The company can seek an exemption from their CBD Program obligations on the basis that the major refurbishment is now underway.
Scheduling conflicts have led to a major upgrade of a company’s office air conditioning system being pushed back by 6 weeks.
The project is still considered to be underway as the contract has been executed.
The company can seek an extension to their exemption from their CBD Program obligations on the basis that the major refurbishment is still underway.
If during the assessment, the Assessor indicates that the rating of the building will not change by half a star or more, then the works are not considered to be a ‘major refurbishment’ in accordance with the Regulations. The disclosure affected building or area is not eligible for an exemption on this basis.
A company has signed contracts to upgrade the lifts and foyer in their disclosure affected office building. An Assessor has advised that this won’t change the building’s NABERS Energy for offices rating by half a star or more.
This means the works do not meet the definition of a major refurbishment for the purposes of the BEED Regulations.
Even though the work is underway, it is not possible to grant an exemption from the CBD Program obligations on this basis. If the disclosure affected building or area is offered for sale, lease or sublease it will require a current registered BEEC a different type of exemption.
Refurbishment is complete
As part of the CBD Program’s compliance monitoring activities, you may be asked to provide information to substantiate that the major refurbishments were undertaken and are completed.
After a major refurbishment project is completed, a building or area is not disclosure affected for 2 years from the date the Certificate of Occupancy (or equivalent) is issued. This is automatic, you don’t need to apply.
If there are staged certificates for different areas of the building, the building is not disclosure affected until 2 years from the date that the final certificate is issued.
The conditions for issuing a Certificate of Occupancy vary between jurisdictions. In many locations, no Certificate of Occupancy will be issued if air conditioning plant items have been replaced but there have been no changes to fire services or the building classification.
A company applied for and received a 12-month exemption while its office building was undergoing major refurbishment.
The work was completed in 6 months but due to the nature of the work, a Certificate of Occupancy (or equivalent) wasn’t issued. This means that the building remains disclosure affected.
Once the exemption expires, if the disclosure affected building is offered or advertised for sale, lease or sublease, it will require a current registered BEEC or other exemption.
After refurbishment
In some cases, a refurbished building might be disclosure affected but not eligible for a NABERS Energy for offices rating. This means that it can’t get a current registered BEEC.
Under the most recent NABERS Rules, if your building is subject to a major refurbishment, it will be eligible for a NABERS Energy for offices rating as soon as a 12-month Rating Period can be completed.
The 12-month NABERS Rating Period can only begin once one of the following requirements is met:
- 75% of the office Net Lettable Area is occupied by tenants; or
- it has been 2 years since the Certificate of Occupancy (or equivalent) was issued.
After a major refurbishment, if a building is not eligible for a NABERS Energy for offices rating you can seek an exemption on the basis that the building or area is non-assessable.
A company has just completed a major refurbishment and received a Certificate of Occupancy, meaning the building won’t be disclosure affected for 2 years.
The company has maintained an occupancy rate in their building above 75% throughout the project.
This means the building can begin its NABERS Rating Period immediately and will be eligible for a NABERS Energy for offices rating after 12 months of data is available from the completion of the refurbishment.
Knowing that after 2 years from the Certificate of Occupancy being issued, the building will become disclosure affected again, the company organises an Assessor to complete the NABERS Energy for offices rating and BEEC application before the 2 years is up.
By starting early, the company is able have the BEEC application approved as soon as the building becomes disclosure affected.
In this example, as the building is eligible to gather NABERS Energy for offices data at any time due to maintaining the 75% occupancy, the owner could voluntarily submit a BEEC application even earlier in the non-disclosure period.
A company’s major refurbishment takes a year to complete, with a 12-month exemption issued about halfway through the process.
Due to the nature of the works, a Certificate of Occupancy wasn’t issued. This means that the building remains disclosure affected.
However, as occupancy remains below 75%, the building is not immediately eligible for a NABERS Energy for offices rating. When the major refurbishment exemption expires, a new exemption is gained for the maximum duration of 12 months on the grounds that the building is non-assessable, because a NABERS rating is not possible.
Eight months after the major refurbishment was completed, the building achieves 75% occupancy and the NABERS Rating Period (12 months of data collection) begins.
The company obtains a third, shorter exemption just to cover the remaining NABERS Rating Period and the 4-month submission period.
A company obtains a 12-month exemption due to major refurbishment works.
When the works are complete, a Certificate of Occupancy is issued. The building automatically enters the 2-year non-disclosure period.
Eighteen months after the Certificate of Occupancy was issued, occupancy reaches 75%, which means the NABERS Rating Period (12 months of data collection) can begin.
The building becomes disclosure affected 6 months later, when the Certificate of Occupancy is 2 years old.
Although the building is now disclosure affected, it is still non-assessable, as the occupancy of 75% has only been achieved for 6 months.
The NABERS Energy rating can’t be obtained until an Assessor has collected 12 months of data based on occupancy of at least 75%. Once 12 months of data has been collected, the Assessor applies for a NABERS Energy for offices rating, which can take up to 4 months to process.
The building is therefore disclosure affected, but non-assessable, because only 6 months of data is available so far. The company obtains a 10-month exemption to cover the 6 months remaining in the Rating Period, and the 4 months for submission.
A company obtains a 12-month exemption due to major refurbishment works.
When the works are complete, a Certificate of Occupancy is issued. The building automatically enters the 2-year non-disclosure period.
Occupancy only reaches 60% during this period so the NABERS Rating Period cannot begin.
The building becomes disclosure affected when the Certificate of Occupancy is 2 years old. On the same day, the NABERS Rating period begins.
Although the building is now disclosure affected, it is still non-assessable, as an occupancy rate of 75% has not been achieved.
The NABERS Energy for offices rating can’t be obtained until an Assessor has collected 12 months of data and applied for a NABERS Energy for offices rating which can take up to 4 months.
During the data gathering period, the building owner obtains its second exemption; a 12-month exemption on the grounds that the building is not assessable.
The building owner will need to apply for and receive a further 4-month exemption to cover the NABERS lodgement period. The NABERS Energy for offices rating is certified and then at the end of this third exemption, the BEEC is issued.
