energy efficient windows

See our new regular column on what tenders are out and about for emissions account-keeping, diesel emissions and for work on the Australian Building Codes.

Improvements to the energy efficiency requirements for residential dwellings in the 2022 National Construction Code are one step closer, with tenders closing last week for Technical Services to develop the provisions.

The tender is to develop content for the Australian Building Codes Board, to draft enhanced energy efficiency provisions, according to the tender documents.

Work is expected to start late this year, with an initial timeframe of completion by June 2020 and an option for six month’s extension.

Two sets of recommended options using a “whole of house” approach are to be developed for Class 1 dwellings, Class 2 sole-occupancy units and Class 4 parts of buildings.

Option one will aim to achieve net zero regulated energy through increased efficiency of building services and on-site renewable energy and storage; option two will achieve an “intermediate stringency” between current NCC 2019 provisions and net-zero by identifying a maximum annual energy budget.

The starting point for investigating the building fabric and glazing provisions has been set at 7 Star NatHERS.

Other elements of the work will include an updated NatHERS compliance pathway; updated Verification Methods including the Verification Using a Reference Building method; and, a new VURB method for sole-occupancy units in multi-residential buildings.

Tenders to deal with potential action  on diesel emissions

Did you know the ubiquitous lawnmower can generate 40 times the hazardous emissions of a small car? The issue of off-road diesel emissions is one that has been the subject of multiple inquires at both a federal and state level, however Australia still has no standards for these health hazards.

In this area, we seriously lag behind the USA, China and Europe. Sources of non-road emissions include trains, generators, mining equipment, construction plant, marine outboard motors, lawnmowers and other small plant and equipment.

The Community Affairs References Committee-Senate Standing Impacts on health of air quality in Australia Report delivered in August 2013 found emissions from these sources equalled the emissions of the entire on-road vehicle sector. The pollutants are recognised as carcinogenic, and also contribute to respiratory disease burdens.

Bottom-line benefits from reducing the PM10 particles and nitrous oxides from these sources were estimated to be in the realm of $2.5 billion to $4.7 billion (based on 2008 dollar values) by 2030.

The federal government is currently tendering for a consultant to deliver a cost-benefit analysis of implementing measures to manage the problem.

It’s not a definite commitment to impose standards or limits, rather the analysis is expected to examine the feasibility of measures and whether there is a business case for them.

Tenders close this Friday, October 25 at 2pm ACT time, and the project completion is slated for August 2020.

The analysis delivered by the successful tenderer is expected to include modelling of emissions, population exposure and health impacts. It will also need to refer to work researching health impacts carried out by the NSW EPA and refer to international emissions standards in particular the US EPA standards in developing policy options.

Non-regulatory and co-regulatory measures are to be considered such as Memorandums of Understanding, Industry Agreements in addition to a “phased in” introduction of international standards.

Help crunch the numbers on carbon accounting

Calling all experienced Greenhouse and Energy Audit service providers – the Clean Energy regulator wants you to put in a tender to join a panel of suitably qualified and experienced organisations to assist with the nation’s emissions account-keeping.

The tender to join the panel closes this Friday, October 25 at 5pm NSW/ACT time.

The successful contractors will be tasked with providing audit services for National Greenhouse and Energy Reporting, including the Safeguard Mechanism, Emissions Reduction Fund and Renewable Energy Target, including Emissions Intensive Trade Exposed entities. New schemes that the CER may become responsible for in the future could also be part of the remit. 

The term of the current panel of providers ends on November 1, 2019. The CER noted that since the panel was first established in November 2014, the market has matured and the number of suitably qualified and experienced Greenhouse and Energy Auditors has grown.

The new contract is expected to commence on 1 November 2019 and conclude on 1 November 2022. A two year, two x 12 month extension option will be incorporated into the contract.
