Glazing Efficiency
BackgroundExtensive glass surfaces at the Palais des Nations have a potentially high impact on the energy performance of the building. Ageing windows compromise insulation and increase energy demand. During earlier renovations in 2014, UNOG successfully replaced 1,070 windows, yet 620—equalling 2,241 square metres of glazing—remain in need of restoration and renewal.
ScopeUpgrading the glazing across the Palais des Nations would help boost energy efficiency and sustainability, thereby optimizing budget utilization. The installations can be flexibly divided into several sub-projects.
Impact
Its energy savings (electricity and gas) would result in a cost avoidance of approx. CHF 600'000/year.
CO₂ emissions of approx. 600 tons/year could potentially be evaded through the renewed efficiency.
Estimated Cost
