Embodied carbon is reduced by preserving the historic town hall fabric, avoiding demolition and rebuild, and specifying durable clinker brick with a long service life.

• From the outset in 2017, the project focused on sustainable urban planning and careful renovation of the listed town hall. A key strategy was the preservation of as much of the historic fabric as possible, avoiding the emissions associated with demolition and replacement. 
• The new extension was inserted where a 1960s annex once stood, allowing continuity without increasing the site footprint. 
• Durable, low-maintenance clinker bricks — developed as a custom Hagemeister Sonderbrand Type K185 — were used across both facades and roofs, reducing the need for future replacement. 
• Precast elements with brick slips also supported material efficiency and construction precision.

Operational performance is improved through the use of a combined heat and power plant, triple glazing, abundant daylighting, external solar shading, and concrete core activation.

• Energy and heating are supplied by a combined heat and power plant, ensuring efficient generation. 
• Triple-glazed aluminium windows (Schüco AWS 90.SI+, anodised light bronze) and curtain walling improve thermal performance, complemented by external solar shading. 
• Abundant daylighting reduces reliance on artificial lighting, while concrete component activation (thermal mass activation) lowers energy demand. 

Together, these measures deliver a town hall and library with significantly reduced operational emissions compared to conventional benchmarks.
