The knowledge supplier for the heat and energy demand of homes
De Duurzame Oplossing is a technology company of physicists and engineers. Years of knowledge about energy and homes come together in one knowledge base with validated content, calculators and a rich data model. That is how we make the real heat and energy demand of homes visible, and help organizations make well-founded choices about sustainability faster.
Three founding principles
Three beliefs run through everything we build. They shape how we compute, how we expose our knowledge, and how we work with partners and clients.
Physics-grounded, AI-ready by design
Validated simulations are the foundation. On top of that we build a knowledge base that slots straight into your own infrastructure.
Our visionSupercharge people, not replace them
With AI tools, the work shifts from producing to checking. We make it faster, sharper and more consistent.
The human is the protagonistKnowledge supplier, not tool vendor
We are the supplier of validated data, calculations, formulas and knowledge about residential energy. You can work with us in three ways: partnership, integration and consultancy.
Three waysFast, steerable and flexible
Our knowledge moves with your situation, audience and ambition, without you having to build, manage or maintain anything yourself. We base it on unique, validated data and models from our own R&D team and on current knowledge of the Dutch market.
Here is what it gives you:
- Fast: save a great deal of time.
- Flexible: adjust straight to your question, project or audience.
- Cost-saving: use built-in expertise.
Result: you can focus on what really counts for your organization. Spreading and applying knowledge.
The knowledge base, in four parts
Four parts working together: curated content, calculators, a data model and a way of working — designed to land inside your application or project.
Curated, AI-ready content
A growing knowledge base covering sustainability, energy systems, building physics, subsidies and regulations. Structured for direct use by LLMs and agents, or through a traditional front end.
A wide range of calculation tools
Calculators for heat demand, energy use, yield, payback periods and scenarios — all drawn from the same validated models, with consistent outputs across every surface.
A rich data model for households
A flexible model describing homes, residents, appliances and consumption at the level of detail you need. Build individual households, compare measures, model neighbourhoods.
Working together
From a partnership to a connection with your own system, or a sparring session about a single question. There are several ways to put our knowledge and expertise to work. Find out which form fits your question.
