Two buildings may look alike from the outside, yet their energy usage can differ dramatically. Experience has shown that assumptions or general solutions are not enough – improving energy efficiency requires understanding how a building truly behaves. In this post, I explain why, and how Jokons Oy helps property owners find out where energy is actually going – and what actions make sense.

Appearance Doesn’t Tell the Whole Story
Property owners are often surprised to discover how two nearly identical buildings can have vastly different energy consumption. The reasons typically lie in a combination of structure, systems, and usage:
Is heat distribution well balanced?
Does the ventilation work as intended?
How is the building used in daily life?
What are the actual indoor temperature settings and usage times?
These questions can't be answered by visual inspection or broad claims about savings.
Energy Doesn’t Disappear – It’s Used Somewhere
To make smart decisions about energy efficiency, one must first understand where energy in the building is truly going. At Jokons Oy, we do this by modeling the building’s overall energy balance.
This means we identify:
Where energy is coming from
How it’s distributed (heating, ventilation, hot water, losses, etc.)
Why current consumption is what it is
The result isn’t just a report – it’s a practical foundation for decision-making: which measures are truly worthwhile in your specific building, and which are not.
Why Independent Advice Matters
There are many solutions on the market, each promising big savings. But without understanding the building's specific conditions, the return on investment is often uncertain.
Jokons Oy acts as an independent expert. We don’t sell equipment or systems – we offer unbiased insight and recommendations based on facts, measurements, and years of experience.
Clarity and Control Over Energy Use
Whether you’re managing a residential building, commercial property, or industrial hall, our approach is always the same:
✅ Independent analysis
✅ Recommendations based on real data
✅ Understanding the whole picture – not just isolated fixes
