Buildings account for approximately 40–50% of global energy consumption. Germany faces the challenge of replacing fossil-fuel heating systems with renewable and efficient solutions under its new Heating Act. Experience shows that traditional building renovations, such as insulation and window replacement, are not sufficient to achieve climate targets. Smart automation has become an indispensable complement.
The Heating Act aims to replace fossil-based heating systems to achieve climate neutrality in existing buildings. Estonian company Bisly supports this transformation through intelligent, real-time energy and building management: heating, ventilation, lighting, and access systems are dynamically optimized to ensure maximum efficiency.
AI-driven automation transforms buildings from passive consumers into active participants in the energy market – a crucial prerequisite for integration into virtual power plants and the decentralized energy transition.
Bisly smart automation as a synergy to traditional renovations
Bisly offers a new generation of affordable, AI-based Building Automation and Control Systems (BACS) that increase energy efficiency and enable smart management across residential, commercial, and hospitality properties. “With Bisly, up to 15% additional energy can be saved on top of traditional renovation measures, and in some cases, external studies even show up to 20% – a clear indicator of what sets our technology apart,” says Ants Vill, CEO of Bisly.
With hybrid infrastructure, Bisly also allows retrofits in occupied buildings. The system is designed so that installation is possible with minimal technical effort, thanks to digital twins and QR code-based setup. This reduces the cost and complexity of traditional systems by 30–50%.
Economic efficiency for housing companies and developers
For new builds, Bisly can reduce costs through digital twin technology to match the price of conventional standalone solutions for heating, ventilation, and access systems. For renovations of multi-family buildings, early studies show potential savings of around 15% with a payback period of 2–3 years.

In Germany, Bisly has already been deployed in pilot projects, for example in collaboration with the One-Gruppe. Early retrofits in residential and administrative buildings have demonstrated that the systems are flexible and easily integrated, even in existing structures. International projects, such as the Crown Estate in London, additionally demonstrate potential savings of 30–40% in commercial properties, underscoring the effectiveness of the technology.
Support through funding programs and data protection
In Germany, intelligent building technologies are eligible for funding: the BEG program supports smart home solutions that increase energy efficiency with grants of up to 30%. KfW programs for age-appropriate construction and accessibility also include smart assistance systems. This financial support makes investments in systems like Bisly attractive for many stakeholders.
Another key aspect of the German market entry is data protection. Bisly ensures GDPR-compliant security: users retain full control over their room data, while third parties only have access to aggregated system information.
Bisly in Germany: market entry and growth
Led by Sascha Stuckmann, Bisly is currently expanding its presence in Germany. Early partnerships, such as with Henko-Service, demonstrate local acceptance. For 2026, 20–30 projects are already planned in Germany, with a long-term target of reaching €40 million in revenue by 2030.
Bisly’s innovative approach was recently recognized through its selection for the Mastercard Lighthouse MASSIV Fall 2025 programme, highlighting the company’s mission to make buildings smarter, greener, and more energy-efficient.
GOOD TO KNOW
- Bisly develops AI-based building automation systems that reduce energy consumption, lower costs, and enhance comfort for occupants.
- Their solutions can be seamlessly integrated into both new and existing buildings, making them smarter, more sustainable, and highly efficient. By combining hybrid infrastructure, digital twin technology, and easy QR-code-based installation, Bisly enables scalable, cost-effective automation that supports the energy transition and climate neutrality in the built environment.
- In the current political and societal discourse around the Heating Act and the energy transition in the building sector, such intelligent automation is indispensable. It ensures that climate protection in residential and commercial properties is not just a vision, but a measurable achievement.
