  • ClearVue has completed design of an Archetype model building of 15,000 m² to demonstrate how ClearVue product can achieve a Net Zero or Near Zero energy-use building
  • Modelling was completed on a design in Toronto, Canada, benchmarked against the Toronto Green Standard (TGS) from 2030  - one of the world’s highest standards of building performance
  • The Archetype was shown to achieve the highest level of performance under the TGS from 2030 (V6 Tier 1) and an ENERGY STAR score in the top 1% of Canadian office buildings for energy performance
  • The Archetype – a computer simulation and detailed thermal model – will support ClearVue’s sales teams when engaging with architects and engineers seeking to design Net Zero buildings

12 January 2022: Smart building materials company ClearVue Technologies Limited (ASX:CPV) (ClearVue or the Company) is pleased to announce the outcome of recent modelling work undertaken in the context of the global ‘Race to Zero’ in construction decarbonisation.  

During the second half of calendar year 2021, ClearVue commissioned energy efficiency and sustainability specialists, Footprint[i] to develop an energy efficient archetype model office building named ‘ClearZero’ (the Archetype) to demonstrate how ClearVue’s world-leading window integrated photovoltaic products can be used to assist in the design of highly energy efficient, energy neutral buildings. 

The objective for development of the ClearZero Archetype was to explore the energy performance of selected energy and design strategies to achieve a net zero energy building design using ClearVue product. 

The Toronto Green Standard (TGS) is one of the toughest building standards in the world with building code requirements in relation to energy use and building thermal envelope stepping up in stages until 2030. The TGS for construction from 2030 onwards (V6 Tier 1) was used as the benchmark to assess the performance of the Archetype.

The ClearZero Archetype was shown to achieve the highest level of performance under that standard.  Footprint confirmed that the modelled building would achieve an ENERGY STAR score of 99 out of 100, putting it in the top 1% of Canadian office buildings for energy performance if built to the Archetype design.

ClearVue’s patented solar glazing technology cuts heating and cooling costs, and improves building energy efficiency, by preventing unwanted solar radiation from entering a window and converting it into electricity using photovoltaic cells.

Integral to the Archetype design was the use of ClearVue’s advanced technology-based building integrated photovoltaic glazing solution across the total building design, and as the primary façade material for the Archetype, including the use of higher glazing to wall ratios on the facades with higher solar exposure.
