The aim of the study was to find out whether the office building could be passive after a thorough facade renovation.
In parallel with our research, another study was conducted into optimisations of the technical installations using dynamic simulations of energy consumption.
The biggest part of the study was a very thorough analysis of the current building envelope. We did this using the as-built file, on-site tours, dismantlements and soundings. We left no m2 untouched.
Within the predefined scenarios, we explored the possibilities of thermally optimising each of the building envelopes. TRISCO software was an important tool here to solve the thermal bridges caused by external support structure. Principle detail drawings were prepared of the scenarios to visualise elaborated and calculated issues.
The higher insulation and airtightness quality of the building envelope after renovation reduces energy consumption for heating, but will extend the cooling season and thus increase cooling costs significantly.
Correct glass selection with sufficient solar control properties is therefore important.
Using SunEye 210 (Solmetric), the shading of the external support structure on the façade was mapped in situ.
For different types of glass, our expert Martijn Vyncke analysed cooling loads, passive solar gains and savings on artificial lighting. From this, he concluded that glass with a good ratio of daylighting versus solar control glass had the best chance of succeeding in achieving the set goal.
We did not recommend a type of glass with a similar golden aspect.
Our study showed that an insulation quality K16 was not feasible within the proposed scenarios. Even in the most conservation-minded scenario where the facade aspect remains completely unaffected, only a K28 was found to be achievable.
