Improving the energy efficiency of a commercial property in downtown Bottrop is one current example of how such buildings can also be transformed into energy-plus properties. Bayer MaterialScience and other companies involved in the EcoCommercial Building Program (ECB) have provided numerous energy-efficient solutions – in particular using polyurethane rigid foam for an efficient thermal insulation – to ensure the building generates more energy than it uses.

Maastricht, April 14, 2015 – Improving buildings’ energy efficiency is key to meeting European and national climate protection targets. Buildings account for over 40 percent of the world’s energy consumption and around a third of greenhouse gas emissions.

Among industrial insulating materials, rigid polyurethane foam has a very low thermal conductivity. Thanks to ongoing raw material developments – often in collaboration with customers – Bayer MaterialScience has kept on improving this material’s insulating performance. When renovating a 50-year-old building, an insulating layer just ten centimeters thick is sufficient to reduce the building envelope’s energy losses by up to 70 percent.

Benefits for consumers and environment alike
While efficient thermal insulation makes a valuable contribution to climate protection and resource conservation, consumers also benefit from lower energy bills. High-durability rigid polyurethane foam lasts for over 50 years, which makes using this material to renovate a property a worthwhile investment. And opting for a thinner insulating layer frees up more space while still providing effective insulation.

Such insulation also boasts excellent green credentials. After the restoration of a building based on current energy efficiency requirements, insulating panels save 70 to 100 times the amount of energy in comparison to the so-called grey energy, which is required to for their manufacture, transportation, installation, dismantling and disposal. Thanks to their closed-cell structure, the foams exhibit good mechanical stability and moisture resistance.

Energy-efficient “Building of the Future” in Bottrop
Improving the energy efficiency of a commercial property in downtown Bottrop is one current example of how such buildings can also be transformed into energy-plus properties. The project is part of the environmental redevelopment of an entire district. Bayer MaterialScience and other companies involved in the EcoCommercial Building Program (ECB) have provided numerous energy-efficient solutions to ensure the building generates more energy than it uses.

As well as utilizing renewable forms of energy such as photovoltaic and geothermal power, sophisticated sunlight management and other measures help optimize the energy balance.

However, the low energy consumption derives from the excellent insulation of the building envelope with its rigid polyurethane foam insulating panels located in the ventilated curtain wall and the flat roof. The rear of the building is clad with an external thermal insulation composite system – and here, too, the insulating layer is made of polyurethane.

This and many other examples provide impressive proof of how rigid polyurethane foam optimizes energy efficiency and achieves climate protection targets in new buildings and also when renovating existing properties.
