OMEGA欧米茄总部

The market shows that a growing number of organisations are looking for and renting energy-efficient, sustainable office space. Oaktree and its project partners are looking to the future and actively helping to shape this trend.

The replacement window is the optimum solution here, because the existing outer window frames and their connections to the surrounding building fabric still offer adequate load-bearing capacity, tightness and thermal insulation. Thanks to our smart concept, we have been able to achieve a really far-reaching improvement in thermal insulation and the usability of the entire construction with a very limited and selective intervention in the building’s structure. It is an ideal alternative to the much more resource, time and cost-intensive option of replacing the entire façade.

We have closed the loop. Old, end-of-life windows are being turned into materials for new, contemporary windows. Our refurbishment concept is also saving on CO2 emissions in many different ways. On the one hand, we are using fewer materials, since we are only replacing the sashes and infills. The Hydro CIRCAL 75R alloy we are using means the replacement process itself has a very small carbon footprint. On the other hand, the upgrade of the façade for higher energy efficiency reduces the heating demand and thereby helps us save on CO₂ emissions in a third way.

To compensate for tolerances and ensure reliable tightness, we developed a project-specific adapter frame with integrated tolerance compensation for the pre-existing window frame.

The new windows and fixed lights with triple glazing achieve a U value of less than 0.99 W/m²K and satisfy all the EGB 55 values specified by the client. They feature an outstanding air permeability Class 4 to EN 12207 and water tightness Class 9A to EN 12208.
