REHAU RENEWABLE ENERGY PRODUCTS SHOWCASED ATBASF CREATIVE ENERGY PROJECT
BASF House, Nottingham University 
REHAU’s Building Solutions division is focused on developing products which are energy efficient and which utilise the inherent features of polymer to deliver environmental benefits.
Most recently, it has been involved as a partner on the BASF House Project at Nottingham University’s School of the Built Environment. This innovative BASF collaboration, which opened at the end of January, is designed to demonstrate how passive heating and ventilation can be successfully achieved in a UK property.
REHAU, whose products have already been used in low and zero energy projects across Europe, has supplied its AWADUKT Thermo ground air heat exchanger for the building, as well as its RAURAIN rainwater management system, PVC-U window frames and flexible polymer pipework.
The unique AWADUKT Thermo system uses ground source energy to provide occupants with a continual supply of fresh filtered air which is pre-warmed in winter and pre-cooled air in summer.
It relies on a network of polypropylene pipes laid around the property at just 1.5m below ground where the earth’s temperature is a constant 8-12ºC throughout the year. Fresh air is drawn through the pipes via an air intake and the solid walled polypropylene acts as a very good heat conductor allowing excellent heat transfer between the ground and the air.
The south facing façade of the building also has two separate REHAU PVC-U window screens in place which capture the solar gain - heating the air for use in the rest of the building. The south facing elevation is almost 100% REHAU glazing and the north facing 30% providing improved quality of life in the home by utilising good daylight. This also cuts the energy requirement to light the home.
The RAURAIN rainwater management system which has been installed collects rainwater in a specially designed underground tank and then distributes it via a filter, pump and separate pipe system for non-potable water requirements such as flushing toilets, washing machines and watering gardens.
REHAU’s market leading PVC-U window systems and polymer pipework for plumbing and drainage have been used on the project because of the favourable environmental performance of polymer materials over more conventional alternatives.
