Passive building technology
Passive systems engineered from first principles.
Summotive® develops building technologies grounded in thermodynamics and materials science that reduce operational carbon in the built environment - without active energy systems; every performance claim independently verified by accredited laboratories.
The built environment problem
Buildings produce 37% of global energy-related CO₂ - 28% operational, 11% embodied. Two-thirds of the 2050 building stock already exists today. Decarbonising the existing stock is not optional; it is the only viable path.
Engineering approach
We apply thermodynamics, fluid dynamics and materials science in place of active energy systems - the laws of physics require no maintenance. Every product is independently measured by accredited laboratories under reproducible, controlled conditions; our results are based on measured data, not simulation models.
The regulatory inflection point
2026
LEED v5, BREEAM New Construction and GRESB have made whole-life carbon assessment mandatory - covering not just operational energy but the embodied carbon of materials, manufacturing, transport and end-of-life. The EU Energy Performance of Buildings Directive (EPBD, 2024/1275/EU) requires all new buildings to meet zero-emission building (ZEB) standards from 2030. The question facing investors, developers and contractors is no longer whether a verifiable low-carbon solution is required. But which one.
Engineering principles
Application of the laws of physics - without active energy systems
Retrofit-first - designed for the existing building stock
Third-party verified - accredited laboratory testing, not modelling
Whole-life carbon - durability cuts embodied carbon cycles
Decarbonisation is not a marketing position - it is an engineering problem. We solve it.
Summotive®. Science. Not promises.
