Whilst manufacturers are rightly focused on reducing the energy use of their products, they also spend time finding ways to increase the efficiency of manufacturing and assembly facilities. Rolls-Royce is a good example, having set goals for efficiency improvements.

Baselined on 2014 performance, these targets are to: reduce energy use by 30% (normalised by revenue) by 2020 and reduce greenhouse gas emissions by 50% (absolute) by 2025 (excluding product test and development).

Sustainable infrastructure is key to meeting these challenging goals. Rolls-Royce invested more than $450 million in the development of Seletar, a large aerospace campus in Singapore in 2012. The facility was designed with sustainability criteria in mind – primarily energy efficiency, water efficiency, environmental protection, indoor environmental quality and high environmental building performance.

The building cooling system has been optimised to provide best practice system efficiency, with a heat recovery system to control building humidity and condensate water recycling. The buildings are also orientated to minimise solar heat gain. A system which manages storm water, collects rainwater and irrigates the grounds, is also in place. The buildings were all constructed using sustainable construction materials.

The Seletar campus has been awarded a platinum rating by the Singapore Building Construction Authority Green Mark scheme. The scheme recognises the highest levels of environmental design in construction and the use of green building technologies.

Meanwhile, in Bristol, UK, a state-of-the-art new LED lighting system will result in an estimated 78% reduction in lighting energy consumption at the site, as well as reduced maintenance costs. Prior to the new lighting system being installed a trial was carried out to encourage employees to feedback on their personal preferences on a range of different LED lighting options. On completion of the trial a light was chosen with superior illumination levels and the most natural feel.
