Covestro completes sustainable, affordable housing model
The House of nations in Bergisch Gladbach was built with wall panels that have a polyurethane core. Those panels are lightweight, highly insulating and make the building with €1150 per square meter affordable.

LEVERKUSEN, GERMANY: Covestro AG together with industry partners, government agencies and society, 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.

Short construction time

“This highly cost- and energy-efficient building was completed in just four weeks. With this pilot project, we want to show how we can work with partners to provide housing quickly and inexpensively. This is an increasing challenge in many cities,” said Dr Markus Steilemann, chief commercial officer, Covestro board of management.

“Communities like Bergisch Gladbach often face the challenge of providing affordable housing as quickly as possible. And this is exactly where the model building comes in. In view of the advantages for all stakeholders, I can well imagine that it will be a success in other locations as well,” said mayor Lutz Urbach.

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 ( a manufacturer of polyurethane rigid foam)– and the drop ceiling likewise are insulated with polyurethane.

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

Cost benefits in construction and occupancy

The elements are simple to manufacture and very lightweight. Each of the large-sized, composite elements weighs only slightly over 100 kilogrammes. Transporting them, therefore, is simple and consumes less fuel. What is more, they are easy to install. Taken together, these factors reduce time and expense both in the preparation phase and on the construction site.

According to Logelis, the total costs add up to €1,150 per square meter, making the building significantly more affordable than a conventionally built structure.

Successful projects in Asia and the Middle East

Covestro for several years has been supporting projects in Asia to provide affordable housing for permanent occupancy. The projects draw on the company’s competence in raw materials and the expertise of customers and were implemented in close cooperation with local government authorities and partners. The projects mainly benefit people who have become homeless after a natural disaster. Numerous housing units of this kind have already been constructed in Malaysia alone.

Industry partners in the Middle East are also using this method to construct turnkey buildings that fulfil local codes.

The residential units are designed for permanent occupancy and to secure the quality of life and health of the residents. The advantages of this model are to benefit over 10 million people by the year 2025.

New business model

The model is based not on donations, but on cooperation between socially minded, often small partners, who build cost-efficiently and retain only a moderate profit margin for themselves in order to support their commercial independence. Covestro manages the collaboration locally and sees to the required permits.

All projects are in line with the company’s integrated sustainability concept. All activities are intended to benefit society while having only minimal impact on the environment. This model for providing affordable housing also contributes to fulfilling the United Nations sustainability goals.
