What is Speckel?

Speckel is a growing platform that aims to enable architects, engineers, planners, contractors and building surveyors to design and build better building envelopes. Through an intricate knowledge of legislation, design, constructability and products, we create applications that:

  • Drive awesome outcomes in building envelope design and construction.
  • Keep the industry ahead of the curve, removing barriers to knowledge via education and openness.
  • Encourage greater awareness and uptake of better envelope building products and techniques.

Where does the name Speckel come from?

Speckel gets its name from its primary goal…. to better specify building envelopes. So the ‘spec’ in Speckel simply relates to specification. The ‘kel’…well, that just makes it sound cool!

Who are Speckel?

The Speckel team are a group of self-proclaimed sustainable design-loving geeks, with toes in building science, mechanical engineering and software development.

Our purpose is simple, to create better opportunities for building design and construction teams to work together to improve outcomes for the built environment. In a world where building envelope design is increasing in complexity and aspiration, we believe we can help create a more coherent and simply approach by encouraging the use of easy to use design tools.

We believe that healthier, safer and more energy-efficient building envelope solutions create the basis for better buildings, with the Speckel platform uniquely placed to guide users through an often-bewildering maze of ideas and requirements.

Can I meet the National Construction Code requirements with Speckel?

The National Construction Code is a performance-based code containing all Performance Requirements for the construction of buildings. It is built around a hierarchy of guidance and code compliance levels, with the Performance Requirements being the minimum level that buildings and building elements must meet.

As there is no obligation to adopt any particular material, component, design factor or construction method, the NCC provides a choice of compliance pathways via either a Performance Solution (Alternative Solution) or using a Deemed-to-Satisfy (DTS) Solution.

Speckel is a Performance Solution (Alternative Solution) that allows building envelope design and construction to directly addresses NCC Performance Requirement. By using calculations and other methods which determine whether a proposed building complies with the relevant Performance Requirements, Speckel may be used if the appropriate authority is satisfied that it establishes compliance with the NCC.

Is Speckel tested and verified?

Speckel undertakes thermal, moisture and other assessments of building envelope designs using established International, regional and best practise building physic equations that have been tested and verified by others.

Within each specification, the approach and assumptions for each unique calculation is stated, including any sensitivities, redundancies and uncertainty observed.

Using these equations, calculations are presented to determine whether a proposed building envelope or whole building complies with the relevant Performance Requirements of the National Construction Code.

Can I specify building envelope design using Speckel?

100%. Speckel uses, as a minimum, all applicable direct, primary and secondary equations stipulated in the National Construction Code. As a Performance Solution, using tested product data directly provided and verified by building envelope product suppliers, Speckel outputs determine whether a proposed building complies with the relevant Performance Requirements.

Does Speckel replace typical consultancy?

The value of a good consultant will not be replaced by Speckel, as Speckel applications are limited. Our aim is to streamline the process of designing the building envelope through clearer specification workflows while maintaining the values brought by a good design team.

Does Speckel verify projects?

No… we are a software company only and are not involved with the verification of individual projects. We want to disrupt how we specify buildings, but not who verifies your projects.

Can I trust Speckel?

We hope so and know it’s important…we have put in 1000’s of hours to rigorously test out platform and are happy to work with you to illustrate the value of using Speckel. Many engineering firms are independently testing to verify the outcomes on Speckel.

Who is the Speckel target audience?

We have developed a platform that is super easy to use, doesn’t rely on engineering knowledge and thus is for the widest of audiences to understand and test building envelope designs against the National Construction Code and other Standards. From planners, architects, main contractors, subcontractors and engineers to building surveyors, certifiers and policymakers, we believe our pricing and value for money will open the door to as many professionals as possible.

What is the difference between the National Construction Code facade calculator and Speckel?

The Australian Building Codes Board have made available a downloadable façade spreadsheet at  https://www.abcb.gov.au/. Speckel maintains the same calculation methodology as per the National Construction Code 2016 and 2019, where applicable. However, Speckel goes onto provide far more advanced calculations and is not a direct Deemed-to-Satisfy Solution.

Speckel is a Performance Solution (Alternative Solution) that allows building envelope design and construction to directly addresses NCC Performance Requirement. By using calculations and other methods which determine whether a proposed building complies with the relevant Performance Requirements, Speckel may be used if the appropriate authority is satisfied that it establishes compliance with the NCC.
