There is a huge opportunity to use resources more efficiently in the building services industry. A groundbreaking initiative led by WRAP and CIBSE will look at how industry can minimise the use of precious materials and resources, cut waste from procurement and encourage recycling


uilding services represent around 35% of the capital cost of a typical


city office building and 40-50% of lifecycle expenditure over a 30-year


period. Aecom estimates that building services represent 2%-12% of the total embodied carbon of a typical building, with highly serviced areas such as trading floors and hospital surgical departments representing the higher end of this range. Finding ways to use fewer precious materials and resources – and reducing waste when repairing and replacing them – could generate considerable cost savings, as well as reduce the impact on the planet. CIBSE has formed a partnership


with WRAP (Waste & Resources Action Programme) to increase awareness of the opportunities and business benefits of resource efficiency. WRAP has appointed Aecom to consult with the building services industry to identify the challenges and opportunities of resource efficiency, and to then prepare CIBSE guidance on the topic. Building services contain resource- intensive, valuable materials including


TAKING STEPS TO ENERGY EFFICIENCY


Five key areas offering opportunities for improved resource efficiency


Now: Compact fluorescent lamps contain mercury rare-earth


phosphors as do LEDs. The future: Organic LEDs containing no rare-earth materials?


Now: A typical lift includes stainless steel, copper, aluminium,


plastic and glass. The future: What are the opportunities for lifts to use alternative materials?


Now: Galvanised steel is often used in ductwork; it has a high embodied energy and also requires zinc. The future: Can we design using less ductwork, or use alternative materials?


Now: Efficient chillers with magnetic


bearings use less energy. However they use rare- earth magnets. The future: Can this be achieved without using rare elements?
