ClearVue-LandVac joint venture moves from development to real-world validation
ClearVue Technologies Limited (ASX: CPV) has commenced the first real-world deployment of photovoltaic glazing technology jointly developed with LandVac, marking an execution milestone following the recently announced Hong Kong joint venture between the two parties. The deployment will provide real-world data for Project Delta and is located at a hotel in Macau under a Letter of Intent with the customer, and targets the global retrofit market for next-generation glazing solutions.
Key highlights from the deployment include:
- A Measurement and Verification (M&V) comparison pitting the new technology directly against existing legacy single glazing under real operating conditions
- Environmental sensors monitoring electricity generation, thermal performance, and air-conditioning energy consumption
- Three Building-Integrated Photovoltaic (BIPV) façade cladding panels with different surface finishes being evaluated for durability, weathering, and maintenance performance
- Independent engineering support provided by erbas
The jointly developed single-glazed insulating photovoltaic window technology was first presented to ClearVue shareholders during the April 2026 Investor Webinar.

What Project Delta is and why the Macau test matters
Project Delta employs a Measurement and Verification methodology to generate credible, comparable performance data. An existing legacy single-glazed window at the Macau hotel is replaced with the jointly developed technology, while an adjacent room retaining the original glazing serves as a direct side-by-side control. This configuration allows sensors to measure electricity generation, thermal performance, and air-conditioning energy consumption under comparable operating conditions simultaneously.
Separately, three BIPV façade cladding panels incorporating different surface finishes will be installed at the site for evaluation. These panels will not be electrically connected during this phase. Their assessment focuses on durability, weathering, and maintenance performance under Macau’s subtropical climate, providing insights into long-term surface performance and maintenance requirements.
Macau’s subtropical climate makes it a particularly relevant test environment for analysing heat transfer and cooling load, given that high humidity and heat amplify the performance differences between glazing systems. Independent engineering support is being provided by erbas, whose involvement will validate the technology under real operating conditions.
Understanding the technology: what makes Project Delta different
Building-Integrated Photovoltaic (BIPV) glazing refers to glass that generates renewable electricity while functioning as part of a building’s façade or envelope. Unlike rooftop solar panels, BIPV glazing replaces existing windows or cladding, making it particularly suited to the retrofit market, where upgrading existing buildings represents a large-scale opportunity without the need for new construction.
Project Delta’s jointly developed technology delivers a dual benefit: it generates renewable electricity and reduces thermal transfer, meaning less heat enters the building through the glass. According to Chief Executive Officer and Managing Director Doug Hunt, the product delivers thermal performance comparable to approximately 1.5 metres of brick wall, while being approximately the thickness of a mobile phone.
Hunt further noted the technology achieves a 20% less solar heat gain coefficient, is approximately three times more efficient than a standard double-glazed unit, and approximately 12 times more efficient than legacy single glazing.
The product also carries a potential carbon reduction benefit on two fronts: reducing operational carbon in buildings through improved thermal performance, and reducing embodied carbon in construction due to its lower weight and reduced material requirements.
| Technology | Metric | Performance Claim | Comparison Basis | Source |
|---|---|---|---|---|
| Project Delta glazing | Thermal performance | Comparable to approx. 1.5 metres of brick wall | Brick wall equivalent | CEO Doug Hunt |
| Project Delta glazing | Physical thickness | Approximately the thickness of a mobile phone | Consumer device reference | CEO Doug Hunt |
| Project Delta glazing | Solar heat gain coefficient | 20% less solar heat gain coefficient | Not specified | CEO Doug Hunt |
| Project Delta glazing | Energy efficiency | Approximately 3x more efficient | Standard double-glazed unit | CEO Doug Hunt |
| Project Delta glazing | Energy efficiency | Approximately 12x more efficient | Legacy single glazing | CEO Doug Hunt |
Three voices on what the Macau deployment means for investors
The announcement carries commentary from three individuals directly involved in the ClearVue-LandVac joint venture. Each offers a distinct perspective on the significance of the Macau deployment.
LandVac Founder, Mr ZHAO, Yan
“The Macau hotel is the first real-world deployment of our work with ClearVue, and it certainly won’t be the last. From day one, our aim has been to develop next-generation glazing products that improve the thermal and energy performance of the building envelope… Legacy single glazing allows significant heat transfer, driving up cooling loads in hot, humid climates, which makes Macau’s subtropical conditions an ideal test environment. A side-by-side comparison with an adjacent room will show us two things: how much electricity the window generates, and what difference it makes to cooling demand. We look forward to applying those insights to the next products we develop with ClearVue.”
CEO & Managing Director, Doug Hunt
“This deployment demonstrates the early execution of our joint venture with LandVac and represents an important step in taking our jointly developed technology from product development into real-world validation… Independent real-world data is an important part of progressing the technology towards broader commercial deployment and building confidence among architects, engineers, developers and building owners.”
Non-Executive Director, Andrew Lau
“Across Asia, improving the performance of existing buildings is becoming an increasingly important priority as governments, building owners and developers seek practical solutions to reduce energy consumption and carbon emissions. The retrofit market represents one of the largest opportunities to improve the energy performance of the built environment, and validation under real operating conditions is an essential step in demonstrating both technical performance and practical application…”
What comes next for the ClearVue-LandVac joint venture
The Macau deployment is positioned as a stepping stone toward broader commercial deployment rather than an endpoint in itself. Independent M&V data generated through Project Delta is intended to build confidence among architects, engineers, developers, and building owners, as noted by Hunt in his commentary.
The global retrofit market, representing the upgrade of existing buildings rather than new construction, is the stated strategic target for the joint venture. Real-world validation under operational conditions is presented as an essential prerequisite for commercial adoption at scale.
ClearVue’s retrofit contract for the Rio Business Centre in Paphos, Cyprus, awarded earlier in 2026, demonstrated the same commercial logic at work: existing buildings with legacy glazing replaced by a solar-generating system, with performance specifications selected as the deciding technical credential over competing suppliers.
For investors, the key signal from this announcement is one of execution: the ClearVue-LandVac joint venture is moving from product development into real-world validation, with independent data expected to support the next stage of commercial progression.
