VURB Assessments

VURB Verification offers a cutting-edge solution for energy efficiency compliance in dwellings, using a Reference Building as its benchmark instead of depending on an Energy Star rating like NatHERS. Our team of qualified professionals is here to help you identify the best options for your development. This report option is available across all States and Territories, with the exception of NSW.

VURB

What is VURB?

Verification Using a Reference Building (VURB) is an advanced method for demonstrating compliance with the energy efficiency requirements of the National Construction Code (NCC). This approach involves comparing the proposed building's energy performance to that of a reference building, ensuring that the new design uses less or equal energy for heating and cooling.

Why Choose VURB Assessments?

VURB assessments offer flexibility and cost savings by allowing for a more realistic and tailored approach to energy compliance. This method is particularly beneficial for projects where traditional compliance methods, such as NatHERS ratings or Deemed-to-Satisfy (DTS) provisions, may be challenging or costly to achieve.

Key Benefits of VURB Assessments

Cost-Effective Solutions
- VURB assessments can help reduce construction costs by optimizing the use of materials and design elements. For example, it allows for trade-offs between insulation and glazing, enabling you to achieve compliance without unnecessary expenses.
Flexibility in Design
- This method provides greater flexibility in building design, accommodating unique architectural features and innovative solutions. It is ideal for projects with high ceilings, large windows, or other distinctive design elements.
Enhanced Energy Efficiency
- By using detailed energy modelling, VURB assessments ensure that your building meets or exceeds the energy performance of the reference building. This results in lower energy consumption and reduced greenhouse gas emissions.

Applications of VURB Assessments

New Residential Buildings
- VURB is an excellent choice for new residential projects, ensuring that your design meets stringent energy efficiency standards while allowing for creative and cost-effective solutions.
Alterations and Extensions
- For existing buildings undergoing significant renovations or extensions, VURB assessments provide a practical way to achieve energy compliance, especially when maintaining parts of the original structure.
Complex Building Designs
- Projects with complex or unconventional designs benefit from the flexibility of VURB assessments. This method accommodates unique features and optimizes energy performance without compromising on aesthetics.

How VURB Assessments Work

Modeling the Reference Building
- The process begins by creating a detailed energy model of a reference building that meets the minimum NCC requirements. This model serves as the benchmark for comparison.
Evaluating the Proposed Building
- An energy model of the proposed building is then developed, incorporating your preferred design elements and materials. The energy performance of this model is compared to the reference building.
Optimizing for Compliance
- If the proposed building's energy usage exceeds that of the reference building, adjustments are made to improve efficiency. This may involve enhancing insulation, optimizing glazing, or incorporating shading devices.
Final Verification
- Once the proposed building meets or exceeds the energy performance of the reference building, a VURB report is generated, demonstrating compliance with NCC requirements.

2. Why is VURB important?

VURB is important because it offers flexibility and cost savings by allowing for a more realistic and tailored approach to energy compliance. This method is particularly beneficial for projects where traditional compliance methods, such as NatHERS ratings or Deemed-to-Satisfy (DTS) provisions, may be challenging or costly to achieve.

3. What types of projects benefit from VURB assessments?

VURB assessments are ideal for:

New residential buildings
Alterations and extensions to existing buildings
Projects with complex or unconventional designs
Large houses, houses with elevated floors, or houses with unique architectural features

4. How does the VURB assessment process work?

The VURB assessment process involves:

Modeling the Reference Building: Creating a detailed energy model of a reference building that meets NCC requirements.
Evaluating the Proposed Building: Developing an energy model of the proposed building and comparing its performance to the reference building.
Optimizing for Compliance: Making necessary adjustments to the proposed building's design to ensure it meets or exceeds the energy performance of the reference building.
Final Verification: Generating a VURB report that demonstrates compliance with NCC requirements.

5. What are the key benefits of VURB assessments?

Key benefits include:

Cost-Effective Solutions: Reducing construction costs by optimizing the use of materials and design elements.
Flexibility in Design: Accommodating unique architectural features and innovative solutions.
Enhanced Energy Efficiency: Ensuring the building meets or exceeds the energy performance of the reference building, resulting in lower energy consumption and reduced greenhouse gas emissions.

6. How long does it take to complete a VURB assessment?

The time frame for completing a VURB assessment can vary depending on the scale and complexity of the project. It typically involves detailed energy modeling and comparison, which may take longer than other compliance methods. For an accurate estimate, it is recommended to contact an experienced energy assessor with your project details.

7. Is VURB more expensive than other compliance methods?

While the initial cost of a VURB assessment may be higher due to the detailed modeling required, it can result in long-term cost savings by optimizing construction materials and design elements. This makes it a cost-effective method in the long run, especially for complex or unique projects.

8. Do I need a NatHERS rating before a VURB assessment?

No, a NatHERS rating is not required before a VURB assessment. VURB and NatHERS are both methods of energy compliance, and you can choose the one that best suits your project's needs.
