Sustainability has become a buzzword all over the world. With building development contributing significantly to environmental changes, the Australian government has introduced the National Construction Code (NCC) to help buildings reduce energy consumption and greenhouse emissions.
The NCC Volume 1, through the Building Code of Australia (BCA) Section J, specifies the energy efficiency requirements for commercial buildings. Two avenues are documented under the NCC BCA Section J – Deemed-to-Satisfy (DTS) method and the JV3 method to demonstrate the sustainability of commercial buildings. In this guide, we will learn the difference between these two methods of NCC BCA Section J. What is the BCA Section J DTS? The fundamental objective of the “Deemed-to-Satisfy (DtS)” assessment is to attain compliance by ensuring all components of the BCA Section J are met. The components include prescriptive examples of materials, design factors, products, and construction and installation methods, which must satisfy the performance requirements stated by the NCC. These DTS requirements fall under the NCC’s nine main sections: Part J0 – Energy Efficiency Part J1 – Building Fabric Part J3 – Building Sealing Part J5 – Air conditioning and ventilation (commonly known as HVAC) systems Part J6 – Artificial lighting and power Part J7 – Heated water supply, spa pool, and swimming pool plant Part J8 – facilities for energy monitoring Moreover, the DTS assessment process for NCC BCA Section J compliance is dependent on some additional factors, such as the building class, the development of which falls under the floor areas of different building zones and the specific climate zones. Another point you should know is the DTS provisions are generic and don’t consider the building’s geometry or unusual conditions. A professional assessor recommends deploying this form of assessment and reporting where building development is simple and doesn’t involve significant design innovations. The process is simple in terms of compilation procedure and, thus, is a faster and economically reasonable solution to assess whether the building development complies with the NCC BCA Section J. What is the JV3 Assessment? To comply with the NCC Section J requirements, the NCC introduced an alternate method to the DTS approach, i.e., the JV3 Assessment method. Implementing this approach, you can include non-compliant provisions in a building and still demonstrate the NCC Section J compliance. Using this approach, you can ignore the undesirable and expensive DTS requirements and instead deploy effective and inexpensive solutions to improve the overall performance and economics of specific building development projects. What is the Difference Between the BCA Section J DTS and JV3 Method? The requirements of each National Construction Code (NCC) section are specified under various sections of the Building Code of Australia (BCA) in the form of Deemed to Satisfy (DTS) requirements. The NCC BCA, Section J report, must state that the specific building meets all the applicable requirements of the BCA’s relevant parts to comply with the NCC requirements. Aside from the DTS requirements of the BCA, NCC also permits a performance-based alternative solution to help demonstrate the compliance of buildings with the requirements of the pre-stated building code. To comply with the NCC’s section J, the JV3 assessment formulates an alternative solution with authorised computer modelling. Wrapping up it all Most councils in Australia ask the building owners to submit the NCC BCA Section J report as a part of the documentation for the construction certificate stage. The report explains the requirements of the BCA Section J for the specific building according to the national and local area regulations. An expert consultant or assessor will deploy the Section J DTS or JV3 assessment to study the design of the proposed development to learn whether it meets specific energy efficiency requirements. Therefore, both BCA Section J DTS and JV3 assessment reports are crucial to constructing energy-efficient, sustainable buildings in Australia.

All new Australian residential construction and renovations costing over $50,000 needs to achieve a 6 star energy rating as outlined in the National Construction Code (NCC). The Nationwide house energy rating scheme, commonly known as NatHERS assessment, provides residential constructions with energy and thermal comfort star rating ranging from 1 to 10. The rating is based upon the structure's design, construction material and location of the project. The Australian harsh and unforgiving climatic conditions necessitate the construction of energy-efficient homes. However, only a few projects were able to achieve 10-star NatHERS rating. While NatHERS assessment is specifically reserved for residential constructions, the BCA section J report deals with commercial constructions. What Is 6-Starts NatHERS Rating? A thermal or energy efficient rating Indicates how much artificial heating and cooling is required to maintain a comfortable interior thermal temperature. Consequently, a six-star rated home will have greater thermal efficiency than a 5 star-rated construction. in simple words, a six-star rated home will most likely consume 24% less energy for artificially heating and cooling a house. What’s Included Within A NatHERS Assessment? A NatHERS assessment evaluates the following components of residential construction: When evaluating a new home and its compliance with a 6-star energy rating, an assessment considers the ‘skin’ of the building and materials that make up the home as well as environmental factors such as climate and orientation. These include:

Passive cooling utilizes the concept of ventilation, unrestricted air movement, evaporative cooling and thermal mass to maintain a cool temperature within the interiors. Passive heating and cooling are important components of the NatHERS assessment.
Wrapping Up Only a few Australian residential constructions have attained the aspirational pinnacle of 10-star energy efficiency. Hire an experienced building consultant to achieve a higher rating and enjoy greater market value and reputation through sustainable design concepts. For all residential buildings and structures in New South Wales, a BASIX certificate is mandatory for obtaining development applications and getting permission for the construction process. BASIX was a sustainability index introduced in 2004 to promote the development of environment-friendly, energy and water-efficient residential dwellings. This article will discuss fundamental facts about the BASIX report and certificate. Elements of the residential project included in a BASIX certificateA BASIX certificate entails the following components of residential development:
BASIX Certificate Is Mandatory For All Residential Projects in NSW.Single Dwellings
Multiple Dwellings
Renovations and Upgradations
BASIX Water, Energy And Thermal Comfort TargetsThe NSW Government’s building performance targets for BASIX include:
BASIX Report Isn’t Legally Valid, BASIX Certificate Is
Costs Associated With BASIX CertificateFees Charged By The Government EntitiesNSW department of planning (BASIX Governing body) charges a certain fee for each certificate created through the online BASIX tool, depending on the nature of the residential development and the number of dwellings within a particular project. NatHERS Certification FeesNatHERS Certification charges need to be paid to release a NatHERS certificate for demonstrating compliance towards thermal comfort levels. Currently, this price is $20+GST/dwelling. Consultation FeesHiring professional building consultants for preparing sustainability reports reduces complexity and makes the entire process seamless. The consultation charges vary depending on the intricacy of a project and your individual requirements. Get a quote from a reputed building consultancy agency to get an approximate understanding of the consultation fees. ConclusionConcerns about climate change, global warming and other degrading environmental events are leading sustainability requirements in the building industry to become more stringent.
To avoid delays in your project due to non-compliance and erroneous reports, it is recommended that you hire an experienced building consultant to assist you in the sustainability conference processes. The National Construction Code (NCC) Australia, previously known as the Building Code of Australia (BCA), requires commercial developments under Classes 2-9 and residential developments not covered under classes 1 to 2 to meet minimum mandatory energy efficiency standards under the Section J Energy Efficiency provisions.
NCC-Volume-1 entails the detailed requirements for the design and construction of commercial projects (Class 2-Class9). BCA Section J regulates the Energy efficiency of commercial buildings. BCA Section J report demonstrates compliance with energy efficiency standards for a particular commercial project. What Is The Overall Objective of Section J Report?
Design Ideas For Energy-Efficient Commercial Buildings Considering Building Orientation To Maximise Natural Energy Inputs By ensuring the correct building orientation of your commercial development, you can take better advantage of natural energy source sunlight and strategically place windows accordingly. Such designs reduce reliance on artificial lighting and heating requirements during the day, enabling the occupants to save more on their utility bills. Also Read This : A Short and Sweet Guide To BCA Section J Report Don't Forget The Aspect Of Retrofitting In The Future. Designing for sustainability is not a one-time thing. In fact, timely renovations and modifications enhance the building's performance. With better performance, you might even be eligible for earning a fair NABERS Rating. That way, you can find high-value buyers and investors who can have a good foundation to start on after purchasing, rather than starting from scratch themselves. Have The Correct Insulation Insulation is a vital element for making commercial buildings energy efficient. First, select a green insulation material such as polystyrene or cellulose. Then, ensure that you insulate your entire commercial building thoroughly and with great precision. With proper insulation, you won't need to worry about hot or cold air escaping, thus helping you save substantial dollars on your utility bills. Insulation constitutes an important part of the BCA Section J report. Strategically Choose The Windows The types of windows you install within your building premises make a considerable difference as well. Selecting double or triple-paned and low-emissivity windows can enhance insulation and protect the building further against unnecessary energy losses. The occupants can enjoy even more saving on your utility bills. Use Insulated Concrete When constructing an energy-efficient commercial project using energy-efficient construction materials such as Insulated Concrete Forms (ICFs) is an excellent option. Coupled with metal framing, such materials design a more resilient, energy-efficient commercial structure, offering extra insulation, and can withstand unforgiving weather conditions with ease. JV3 assessment allows great flexibility in choosing building materials and architectural designs for maximising energy efficiency while maintaining aesthetics and functionality. Choose A High-Efficiency HVAC System The HVAC system is another vital component of any home or commercial space. This system regulates the entire heating, ventilation, and cooling of the whole building. Thus, choosing Energy Star-rated heating and cooling machines is necessary. Additionally, efficient sealing of the building to prevent loss of energy using a sealant makes your building more energy-efficient. Part J5 of the BCA Section J report highlights the details of the HVAC system. Sustainable Building For A Greener Future Using energy efficiently saves businesses and buildings significant dollars and helps the earth along the way. The design ideas above are just the tip of the iceberg. With an open-minded approach and energy-efficiency aim in mind, the commercial developments of tomorrow can set the gold standard for sustainable energy usage. The NABERS Sustainability Rating, also known as National Australian Built Environment Rating System, has been established to encourage, promote and reward project owners, developers, and building owners for reducing carbon footprints and playing their critical part in combating climate change evil. The built environment is one of the largest contributors to climate change – generating 30-40% of global greenhouse gas emissions. Therefore, the Australian Government targeted the biggest carbon production source for driving significant changes to restore the ecological balance. The NABERS rating tool has been leading the way for sustainability in Australia's property industry for over 20 years now. Maintaining and improving building efficiency through NABERS requires consistent monitoring and assessment. What Is NABERS Rating? NABERS is an Australian building performance rating system that measures and ranks the environmental performance of several types of developments using a 6-star scale. NABERS is applicable for both commercial and residential developments, including office spaces, hotels, shopping complexes, and apartment buildings. The NSW Environment and Heritage Office manages the NABERS Rating system on behalf of the Australian, state, and territory governments. NABERS Rating For Different Developments NABERS Office Ratings Commercial office spaces and tenancies across the country can measure sustainability performance with NABERS office ratings. While NABERS includes indoor environment quality, water consumption, and waste management for office buildings, BCA Section J exclusively deals with the energy efficiency of the commercial buildings. Statistics revealed that commercial office building owners who have registered for ten NABERS ratings and made modifications to improve results in the subsequent assessments had reduced energy consumption by 40% on average. NABERS Office Rating is applicable for:
NABERS Rating for base building:
NABERS tenancy rating assessments are specifically designed to assess the efficiency of tenancies within an entire commercial building, informing individual businesses of their energy and water consumption and overall sustainability performance. NABERS Whole Building Rating includes the following:
The NABERS rating for Apartment Buildings represents a superior advantage for the residential sector, enabling apartment buyers and project owners to become aware of the development's sustainability performance even before investing. By carefully focusing on reducing apartments' carbon footprint, owners and tenants can enjoy significant energy savings. An apartment building refelecting a high NABERS rating indicates that it is:
NABERS For Shopping Centers NABERS rating for shopping centres evaluates the energy and water performance that comes under the management of a shopping centre owner, including:
NABERS Rating For Hotels The NABERS rating system for Hotels measures the environmental efficiency of hotels across Australia. NABERS rating is different from the star rating system that rates a hotel according to the services they offer. It rates:
NABERS rating for hotels reflects the commitment of a hotel or chain of hotels to the environment. This is a great sustainability tool empowering owners to identify cost-saving opportunities and minimise their carbon footprint. NABERS Hotel rating system includes:
NABERS For Data Centers Data Centres can also benchmark their sustainability performance using the NABERS rating tool. NABERS energy ratings for data centres can be defined as a collection of performance metrics for calculating the energy efficiency and environmental impact of networked computer centers and facilities. Also Read This : NABERS Ratings: A Comprehensive Guide NABERS rating for data centers is categorized into the following groups:
Sustainability has become the keyword for every industry, and the real estate industry is no exception. Therefore, to ensure that the building industry is strictly adhering to the sustainability standards, the Australian Government has introduced various regulations and standards to promote sustainable development in both residential and commercial sectors.
BCA Section J, NABERS Rating and JV3 modelling are some of the initiatives started by the Government for commercial sector sustainable building development. Why Are Environmental Friendly And Sustainable Buildings Necessary? Buildings contribute to 40% of the global greenhouse gas emissions and consume approximately:
NABERS Rating NABERS was launched to influence builders and project owners to put sustainability commitment at the forefront. NABERS (an acronym for the National Australian Built Environment Rating System) offers easy, trustworthy, and comparable sustainability measurements across several building and development sectors, including offices, shopping centres, hotels, apartments, data centres, etc. NABERS provides a star rating from one to six for indicating building efficiency across:
JV3 Assessment JV3 is the alternative assessment method for commercial projects, which involves a reference building to compare the total assumed energy consumption of proposed development with respect to their location and climate. There are several reasons to consider the JV3 assessment as a part of your new design. Buildings replicating the design, layout, and construction materials, can have a different energy consumption situated xx kilometres away. Due to elements like its geographical location and climatic zones, the annual energy consumption can be considerably different. This assessment involves the comparison of a proposed commercial project with a DtS reference building while considering the certain location and weather data of the proposed building. The proposed construction’s annual energy consumption should not exceed the DtS reference building’s annual energy consumption, thus enabling greater flexibility. Connect with professional building consultants to get your sustainability assessment done seamlessly and with fewer chances of error. Energy-efficient commercial developments are crucial for a positive environmental impact. Environmentally friendly buildings save money on energy bills, reduce greenhouse gas emissions, and help owners and renters project an environmentally conscious image. Industry practitioners must maintain specific construction standards-compliant with the Building Code of Australia (BCA) technical requirements. Also, energy-efficient measures need to be considered while developing new constructions. This leads us to the BCA Section J report and JV3 Assessment for sustainability measurements of buildings. But, first, let's find out what sustainability of a building means. What Is Meant By Building Sustainability?In practice, achieving sustainability entails living in peace with nature, taking social, environmental, and economic factors into account when making decisions, and lowering our carbon footprint by less energy and water usage. Social sustainability is equally critical, and efforts to create a safe and healthy community are frequently linked to economic and environmental goals. What Are The Ways to Measure Building Sustainability?Buildings around the world use a lot of energy. Green Star, NABERS, JV3 Assessment, BASIX and DtS are the most common evaluation systems used in Australia to measure the sustainability performance of buildings, including energy performance. Industry professionals need to pick the correct evaluation tools to assess their buildings' sustainability performance. Each of these systems employs various evaluation techniques, including simulation-based or indicator-based evaluation, to evaluate different types of constructions. The Curious Case Of Large Boarding HousesThese evaluation systems assess the energy usage of different classes of buildings. The large boarding houses fall under the class 3 category of buildings. Initially, both BASIX and Section J were applicable for large boarding homes. However, with the new set of regulations, the Dept. of Planning has announced that no BASIX certification will be required for large boarding houses (Class 3 buildings effective from March 2022. These buildings will be assessed under the Building Code of Australia for energy efficiency, National Construction Code and Australian Standard AS/NZS 3500 for water efficiency. Therefore instead of BASIX or NatHERS, now BCA Section J Report will be applicable. So, what's exactly a large boarding house?
However, the alternative evaluation method is used upon meeting only the first criterion for these boarding houses. Furthermore, buildings that comprise mainly serviced apartments are not qualified for an alternative assessment. Also, a BASIX assessment will be conducted for small boarding houses accommodating 12 people or less. Professional building experts have extensive experience in preparing BASIX certificates and Section J report for projects, large and small. Contact the BASIX consultants for a cost-effective energy assessment service today! What Is A BCA Section J Report?
However, if your project design cannot conform to these high requirements, or if you want to change any aspects of the building's design to make it more cost-effective and aesthetically pleasing, you can use the JV3 assessment technique. What Is A JV3 Assessment Method?The JV3 Assessment is an evaluation approach for non-residential buildings that compares new buildings' overall estimated energy usage to a reference building, considering climate and location. Using particular computer software with acceptance criteria and completing relevant tests, a JV3 approach entails generating a 3D model of the building with the precise location, orientation, and climatic information of the surroundings. A Section J consultant will require the following information.
ConclusionThe building sustainability concept emphasises living in harmony with nature while retaining comfort and efficiency. With some effort on our side, we can plan our lives without squandering natural resources or harming the environment.
Therefore, it is necessary to get your building certified by sustainability assessors to ensure proper usage of non-renewable resources. Get your building plan verified by the experienced and professional Section J consultants ASAP! Green buildings have recently gained popularity worldwide for their efficient energy use and reduced waste production. These buildings frequently include methods to reduce energy consumption, including the energy necessary to collect, process, deliver, and install building materials and the operating energy required to supply cooling, heating, and equipment power services. Such constructions are rated with NABERS rating, JV3 assessment, Green Star, etc., to check for their energy efficiency. For residential buildings, BASIX and NatHERS assessments are used as sustainability rating standards. What Is A Green Building?Green building, also known as ecologically sustainable construction, refers to a real-estate structure/development and the use of environmentally friendly and resource-efficient (energy, water, thermal comfort) methods throughout the development's life cycle. Features of a Green Building.Any structure, whether it is a residence, an office, a college, a medical facility, a community centre, etc., can be a sustainable or a green building if it has the criteria stated below.
Benefits of Green Building?There are several financial and ecological benefits of green buildings that traditional structures don't provide. Let's first focus on the economic benefits of these sustainable structures. Financial BenefitsCost savings from reduced water, energy, and waste, cheaper operations and maintenance expenses, and improved tenant productivity and health are all advantages of green buildings. Operating expendituresGreen buildings can reduce minimise eneryg and water use, thus lowering long-term operating and maintenance expenses. The energy savings often outweigh any cost premiums connected with planning, design, and construction within an acceptable payback period. Attracting more valuable clientsMany customers are environmentally conscious and look for companies that share their beliefs. Recently more and more people prefer eco-friendly houses over traditional buildings. Green buildings are believed to affect the well-being and health of occupants positively. Additionally, the design features and internal environment of green buildings have been shown to boost the productivity levels of workers. So, these buildings are proving to be financially beneficial for businesses. Costs of design and constructionAccording to research, green buildings do not have to be more expensive, especially with proper design, program management, and environmental plans. The construction costs of the buildings can come down substantially. Ecological BenefitsThe ecological benefits of green buildings include: Temperature regulationGiven the rising temperatures year after year, it is more prudent to invest in sustainable construction, which helps control the temperature considerably. Structures with green roofs stay far cooler than ordinary buildings, which is an undeniable benefit for people. Furthermore, the flora around the building generates dampness, which produces a pleasant climate within and around the structure. JV3 assessment allows greater design flexibility to ensure better thermal efficiency even with intricate designs. Reduced energy wastage and pollutionGreen buildings may substantially reduce energy usage through improved airflow, natural sunlight, and the utilisation of renewable energy sources. The use of locally available materials during the construction of green buildings can help to reduce pollution caused by transportation. The building design includes measures to reduce the wastage of water, power, and other resources. Water conservation can be achieved by recycling water, installing water-saving faucets, and harvesting rainwater. Australian Tools To Ensure Green Buildings.Green StarGreen Star is a globally recognised grading system that establishes the benchmark for healthy, sustainable buildings and environments. It is a flexible rating system that may be used on any project, whether it's a new or old structure. NABERS RatingNational Australian Built Environment Ratings System or NABERS rating is a national environmental rating system that assesses a building's or tenancy's operating efficiency in terms of energy and water usage, indoor air quality, and management of wastes. BEECAccording to the Building Energy Efficiency Act, any commercial building above 1,000 square meters (sqm) must obtain a current Building Energy Efficiency Certificate (BEEC) when being sold, leased, or sublet. BCA Section JThe BCA Section J of the National Construction Code ensures that the commercial buildings' construction plans and architectural details allow for effective energy use. JV3 assessment and DtS MethodJV3 assessment is an alternative evaluation approach for non-residential buildings that compares new buildings' overall estimated energy usage to their climate and location using a reference building. When energy efficiency rules were initially established in the Building Code of Australia (BCA), the Elemental Provisions technique became famous, also called the Deemed-to-Satisfy (DTS) method. The assessment procedure includes evaluating the proposed building's development to the National Construction Code's requirements (NCC). The assessment yields a stringent pass/fail outcome with no room for error. For Residential Structures- NatHERS and BASIX certificationThe Nationwide House Energy Rating Scheme (NatHERS) assigns a star rating to a resident based on its thermal comfort levels. A high star rating means using less energy to keep the internal environment of the house comfortable. BASIX is also a regulatory certificate that verifies that a proposed project meets standardised energy, thermal, and water specifications. ConclusionLiving in balance with nature while maintaining comfort and efficiency is central to the green building philosophy. It is feasible to organise our lives without wasting natural resources or damaging the environment with some effort.

Most developers and project owners venturing into the residential building sector had one question in common-- Which thermal assessment model should be used for accessing large boarding hoses (Class 3 buildings)? Should it be BASIX at the Development application stage or BCA Section J at CC (Construction certificate stage)? So, why the big confusion? According to Government guidelines and NCC/BCA (building code), class 2 and class 4 construction required BASIX certificate during DA. While class 3 buildings required a Section J report at the construction certificate stage. However, various councils started demanding BASIX certificates as well. Additionally, the court also ruled that BASIX was necessary for large boarding houses because of the definition of dwelling defined in the Environmental Planning And Assessment Act. “Dwelling” in a BASIX building is defined as a room or suite of rooms utilised, modified, adapted, occupied, or constructed for use as a separate domicile. BASIX Challenges For Large Boarding HousesHowever, BASIX presented two complications for large boarding houses: 1. BASIX simulation software was not originally developed to assess large boarding house buildings. Therefore, project owners, building consultants or developers had to use the software for Class 2 buildings (multi-units) which returned skewed results; and 2. BCA Section J was still applicable at the later Construction Certificate stage. This led to two different sets of sustainability requirements applied to one single development. The NSW Department of Planning introduced an alternative thermal assessment for large boarding houses to minimise these complications. This assessment process combines BASIX and Section J in a way that they complement each other. Section J can be assessed through JV3 assessment or DtS assessment. Which Constructions Qualify For Large Boarding Houses Thermal Assessment?NSW planning portable introduced an alternative thermal model known as the large boarding house thermal comfort method. This method streamlined the process for fulfilling a BASIX assessment of Class 3 buildings (large boarding houses). The alternative assessment was also applicable to student accommodation, given the development meets all the following criteria:
How Does The Large Boarding House Thermal Comfort Method Work?The alternative assessment method for Class 3 buildings is known as the Large boarding house thermal comfort method. The method is similar to a standard BASIX assessment, with certain differences. To use this advanced thermal assessment method, you can follow the steps as explained below:
If your Project fulfils all the eligibility criteria mentioned above, the BASIX online tool will automatically enter heating and cooling loads values equivalent to the heating and cooling limits pre-defined for the climate zone of your Project. Thus, with this method, you don’t require to assess the thermal comfort of your Project according to the BASIX protocols. Instead, you’ll require to perform the thermal comfort assessed at a later stage (for obtaining the construction certificate) under BCA Section J provisions of the National Construction Code (NCC) – Vol 1. The BASIX Certificate will clearly mention an additional commitment requiring Section J assessment prior to obtaining a construction certificate. However, you’ll need to complete the other two sections of the BASIX assessment, including passing the Energy and Water sections. Remember, your BASIX report and certificate will not specify the values of the heating load, and cooling load since the thermal comfort assessment section has not been completed. What If Your Project Doesn’t Qualify For Large Boarding House Thermal Method?If your boarding house projects meet the first criteria for large boarding houses but do not fulfil the second and/or throat criteria, you can apply for an alternative assessment for large boarding houses, as mentioned below. This alternative assessment is only applicable for the following development:
If your Project constitutes a small boarding house (designed for accommodating 12 people or less, with a total floor area measuring 300m2 or less), you need to complete a BASIX assessment utilising the single dwelling tool and assess the whole building’s thermal comfort through DtS or JV3 assessment. What Are The Benefits Of a Thermal Assessment For Large Boarding Houses?Reduced Cost Of ConstructionWithout thermal modelling for large boarding houses, you’ll require to apply two sets of thermal assessment protocols. Thus the construction cost will rise substantially. Reduced Intricacy and PaperworkTwo sets of thermal assessments will lead to more complexities while complying with BASIX. Additionally, more documentation and paperwork will be required. How Professional Services For Building Consultant Can Help?Building consultancy agencies have experienced build sustainability experts with years of experience on various residential and commercial projects to help you with your BASIX and Section J Compliance.
In real estate documentation, knowledge is the actual power. Hire a renowned and experienced building constituency agency for your real estate projects. JV3 is an alternative solution (also known as energy performance solution) for non-residential structures when attaining energy compliance is impossible or costly with the ‘Deemed-to-Satisfy’ (DTS) method. JV3 assessment is similar to modelling residential dwellings for thermal comfort compliance using NatHERS software. The JV3 method involves a reference DtS building to compare the total energy utilisation to that of the new commercial development. The annual energy consumption of both buildings is calculated using simulation software. The software must be approved by ABCB (Australian Building Codes Board) Protocol for Building Energy Analysis. Section J compliance is attained only when the annual energy consumption of the proposed commercial development is less than the reference DtS building. When Do You Require JV3 Assessment?A JV3 verification can be helpful in the following situations:
Fortunately, even when DtS compliance methods make it challenging to attain energy compliance standards, the JV3 assessment can be a good alternative. Before we discuss the benefits of the JV3 verification method, let’s understand how the process (energy compliance solutions) works. How Does JV3 Modelling (Energy Compliance Solutions) Work?The National Construction Code (commonly known as NCC) has standardised construction/glazing levels to attain compliance. However, the NCC allows certain flexibility. You can justify and elaborate that your commercial construction has achieved a performance as good as the prescriptive method (DtS approach) using alternative assessment. In such cases, you can balance certain low-performing components such as glazing with high-performance design elements such as insulation. In simple words, you have the flexibility to swap building components to achieve energy compliance. JV3 assessment is applicable for
Commercial buildings include residential portions of hotels, offices, shops, restaurants, cafes, storage units, factories, hospitals, clinics and other public utility spaces. Pre-requisites for JV3 AssessmentTo prevent any poor quality outcomes, abusing the provisions and duplicacy, the NCC regulates certain aspects of the JV3 Performance Solution. These include:
What Are The Benefits Of the JV3 Assessment?Although the costing and the method of JV3 modelling might be more than DtS, it can be beneficial for the following reasons:
DtS is a simple and cost-efficient solution. But it doesn’t consider the following: Thermal interaction of building fabric materials.
All these elements play a critical role in improving the energy efficiency of the building. Thus the construction ends up becoming expensive. Connect with an expert building consultant to get started with the JV3 assessment of your commercial venture. |
