BAL Reports. Bushfire Attack Level (BAL) Assessments Sustainability WA can help. A Bushfire Attack Level (BAL) Assessment is a means of measuring the severity of a buildings potential exposure to ember attack, radiant heat and direct flame contact in a bushfire event, and thereby determining the construction measures required for the dwelling. The BAL assessment takes into account several factors including the Fire Danger Index, the slope of the land, types of vegetation and how close it is to the proposed building. Once a BAL is calculated, building construction requirements can be calculated from the relevant sections of the Australian standard to ensure the correct resistance to bushfires. These requirements take into account the BAL rating for attack from burning embers, radiant heat and flame contact.

The Bushfire Attack Levels are broken down into 6 categories: BAL Low There is insufficient risk to warrant specific construction requirements Ember Attack BAL Flame Zone. Commercial Energy Efficiency. From small office refits to new schools, hotels and apartment complex’s Sustainability has both JV3 and Deemed to Satisfy reports available. Let Sustainability WA assist you with your next commercial project by providing an easy to read, cost effective solution. We have 2 options available for Section J Compliance: Deemed To Satisfy Deemed To Satisfy provides the least flexible way to achieve compliance of energy efficient home design elements but can still be useful in some circumstances, particularly light weight constructions. The BCA dictates the insulation or performance levels you need to comply with for each energy efficient home design element. For example, a floor will have to have a certain R value, as well as the walls and so on.

This often makes it difficult to comply with this method. As always energy efficient home design will be easier with Sustainability WA and we will find the correct assessment method for your project. JV3 Assessments Our Service includes: Green Star Services. Sustainability WA is able to take care of all your energy efficiency requirements. Green Star is a national rating system for buildings and communities that goes beyond the requirements of the Building Code with the aim of establishing buildings and communities that use less power and water as well as promote healthier places to work and live. There may be a number of reasons why you are interested in a Green Star Assessment and wish to engage in our services: Your development is in a Metropolitan Redevelopment Authority area and you need an accredited Green Star Consultant to comply with their requirements.Your development is for a government body and they have requested a minimum Green Star level.Your development guidelines mandate a minimum Green Star Rating.You or your client wish to ensure the development is sustainable and liveable and take advantage of the benefits listed below.

Some of the benefits of having your project assessed against the Green Star criteria are: Basix Assesment. We provides an easy to read & cost effective solution Basix is a sustainable planning measure implements by NSW which aims to make all residential dwellings energy and water efficient. A Basix assessment considers water use, Energy Consumption and Thermal Comfort. A BASIX assessment is required as part of the planning process and is needed before plans are lodged to the council.

The BASIX assessment measures your proposed development for sustainability against BASIX targets that are based on the NSW home benchmark average. Once your design has complied with BASIX a BASIX certificate can be printed and attached to your development application for submission to the council. If your proposed design does not comply with BASIX due to conflicts with heritage controls or because it uses a new technology not recognised by BASIX, an alternate assessment can be requested.

The wide experience from out team means whatever development you are working on, the construction type or size, we have the experience to ensure you get the best result from your energy efficiency certifications. Additions and alterations without the headaches Did you know regulations for additions and alterations are changing and will soon demand 6-star compliance? We did. In fact, Sustainability WA helped develop the protocol governing additions and alterations.

There will be a number of options for compliance when the 5 star exemption lapses in May 2015. The first will be to comply with the energy efficiency requirements of the current NCC as do new houses. The second will be to obtain energy efficiency certification using the protocols as endorsed by the Building Commission of WA. What does this mean? In general terms: How to comply? Most importantly the whole house, even the portions that will be unaffected by the additions and alterations, needs to be documented. Got a question – ask us. Latest Update: Changes to Energy efficiency Requirements for Alterations and Additions.

As promised in our last update we are filling out some of the detail for Alterations and Addition requirements now that the official protocol has been released by the Building Commission. The protocol and documentation to be used with the protocol is available here: Building Commission Bulletin – Alterations and Additions There will be a number of options for compliance when the 5 star exemption lapses in May 2015. The first will be to comply with the energy efficiency requirements of the current NCC as do new houses. The second will be to obtain energy efficiency certification using the protocols as endorsed by the Building Commission of WA. Why the need for the protocol? When a HERS home energy rating system program is used the whole house must be assessed. To counter this, the protocol has been introduced. What does this mean? In general terms: How to comply Most importantly the whole house, even the portions that will be unaffected by the additions and alterations, needs to be documented.

Sustainability WA and Energy Efficiency. When asked about our work, or about our qualifications regarding sustainability, from our own experiences, the response is often understood as dealing with solar panels or being involved in other clichéd sustainable actions. While such technologies and actions can play a role in an approach to the sustainable dichotomy these are just a fraction what we do and know.

There is a whole lot more that could be understood to what energy efficient home plans sustainability is. Knowing the full spectrum of what sustainability is can assist in making certain adjustments to making life for yourself, family and community a whole lot better. The following articles in this category will endeavor to educate and bring to attention some important initiatives that can improve your well being, be sustainable, improve your economical status, well-being and help make the environment around you a better place.

The measure of the energy efficiency of a residence is measured as a star rating. More Energy Efficiency Regulation Changes. Lately the building industry has been in a constant state of change. With building regulations changing and then clarifications and amendments, these changes make it hard to keep a handle on where we stand. Energy Efficiency assessments are no different. The change to 6 star regulations in Western Australia last May was a huge change for the building and design industry. This has been followed this May with further changes. The BCA states that a residential energy efficiency assessment that is conducted using the NatHERS protocols and achieves 6 stars have satisfied the energy efficiency regulations.

The NatHERS regulations set out what software can be used and how the assessment must be conducted. So what are the changes and how does it affect you? The changes can be broken into 4 key areas: Zoning Changes When an assessment is conducted a house is broken into zones. There was previously freedom to choose the usage and if the area was heating and cooled.

Colours Obstructions Lighting. 6 Star Certifications. One pathway for proving that you house or building project has met the minimum energy efficient home design standard is to gain a 6 star rating (The minimum energy efficient star rating) using House Energy Rating Software(HERS). This sophisticated software analyses your building plans and assesses the heating and cooling loads required to keep your future house at a comfortable temperature. It takes into account the full building fabric – Roof, Ceiling, Walls, windows and floors – and the heat and cold that can pass through these elements. The Energy rating depends on: Zero stars means the building shell does practically nothing to reduce the discomfort of hot or cold weather, while occupants of a 10 star home are unlikely to need any artificial cooling or heating.

Verification using a Reference Building Method(VURB) Sustainability WA can work with you to tailor an alternative solution for BCA energy efficiency compliance with the Verification using a Reference Building assessment method (VURB). This alternative gives you flexibility to meet energy efficiency compliance and good energy efficient home design by using both the Deemed-to-Satisfy Elemental Provisions method and the thermal modelling software.

The Verification using a Reference Building assessment method uses the Elemental Provisions as a compliance benchmark. A building is modelled with the Elemental Provisions using thermal modelling software to create target annual energy consumption. The building is then designed with your desired specification and this proposed building is also modelled in the thermal software. If your proposed building uses the same or less energy than the reference target then it is deemed to comply. A reference building cannot be labelled as 6 stars but can be more cost effective to construct compared to 6 stars. Elemental Provisions. Residential Energy Efficiency. We have 3 different pathways available to comply with the energy efficiency regulations including: 6 Star Certifications One pathway for proving that you house or building project has met the minimum energy efficient home design standard is to gain a 6 star rating (The minimum energy efficient star rating) using House Energy Rating Software(HERS).
