Model building in Bergisch Gladbach / Germany

Providing housing quickly, cost-effectively and sustainably is a global challenge. This is true above all in low-income and economically underdeveloped regions, but also in places where housing is scarce or expensive, such as in densely populated areas or cities with a high influx of refugees.

Covestro is breaking new ground in its search for creative solutions. Together with industry partners, governments, government agencies and society, the company is developing models of affordable housing and carrying out specific projects locally. One current example is the “House of Nations,” a multipurpose building in Bergisch Gladbach, Germany, that was designed and built by the city administration, the French prefabricated building manufacturer Logelis and Covestro.

All-around insulation with polyurethane

The outer envelope of the model building is fully insulated with polyurethane. Self-supporting, prefabricated elements from Logelis were used for the walls. They comprise a core of polyurethane foam encased in a thin layer of cement. The floors – with insulation boards from puren gmbh – and the drop ceiling likewise are insulated with polyurethane.

Thanks to the excellent thermal insulation of the wall panels, a wall thickness of only 16 centimeters was sufficient. The annual heating energy requirement is designed to be less than 15 kilowatt-hours per square meter, meaning the building fulfills the respective requirements of the passive house standard.

House of the Future in Bottrop / Germany

The ecological rehabilitation of an entire district – this unique project is currently being implemented in the former mining center of Bottrop/ Germany. The InnovationCity Ruhr initiative hopes to serve as a prototype for the renewal of not just the entire Ruhr region, but other industrial metropolitan areas throughout the world. One of the lighthouse projects: a commercial building downtown that after extensive rehabilitation now generates more energy than other newly constructed buildings.

This was made possible by a worldwide network of experts for sustainable building under the leadership of Covestro. They followed a holistic approach combining the various disciplines and coordinating products and solutions to find the best solution with respect to ecology and costs for a specific building.

In the case of the Covestro Building of the Future, as it is now known, the primary measure was to insulate it on all sides using polyurethane, a high-performance insulating material whose components are produced and continuously further developed by Covestro. Heat no longer escapes, and the cold stays outside. Other rehabilitation measures include energy-efficient windows and innovative lighting and building services technologies.

The resultant, drastically reduced energy requirement is covered ecologically by means of a photovoltaic system on the roof in combination with geothermal energy and district heating. The Covestro Building of the Future can therefore serve as a prototype for the rehabilitation with respect to energy efficiency of many similar commercial properties in Germany and throughout the world. More information about the various components is available.

PUReWallTM for residential construction in the USA

The PUReWall™ technology, enables panelizers to integrate higher levels of functionality and quality in a wall assembly that simplifies on-site construction for builders with less waste, time and cost. The end product meets or exceeds International Energy Conservation Code (IECC) 2015 requirements, providing a better wall assembly for homeowners.”

PUReWall™ panels are constructed with insulation (continuous and between framing) installed at the panelization facility. The continuous insulation, with taped joints, also functions as a weather-resistive barrier. Wall assemblies constructed from materials that are air and vapor barriers provide long term durability for years of comfortable and worry-free living.
