TM56: Resource Efficiency of Building Services

Resource security is becoming more of an issue, with risks affecting the availability and price of materials essential to industry. Construction clients are becoming increasingly interested in resource efficiency, particularly in terms of the embodied energy of buildings. Most research into resource efficiency and embodied energy has focussed on building structure and fabric, specifically excluding building services. Building services represent a significant proportion of the materials used in a building. Plant and equipment typically use a high proportion of steel, aluminium, plastics and copper in their construction and use rare earth elements for key components such as permanent magnets in motors and phosphors for lamps.
 
There has been limited research or focus on the resource efficiency of building services in terms of the impacts of manufacturing, construction, maintenance and disposing of the equipment at end of life. TM56 aims to set out the current situation and to raise the issues relating to resource efficiency, rather than providing all the answers to this complex subject.
 
The document aims to:

  • help engineers and consultants to understand the principles and importance of resource efficiency

  • provide guidance on principles and tools relating to resource efficiency

  • set out opportunities to improve the resource efficiency of building services.

 

Sarah Clayton, Head of Products and Services, WRAP writes:

This Technical Memorandum will help develop greater clarity and certainty around resource efficient, low carbon solutions for the entire sector. Now is the time for the industry to capitalise on the opportunities that will arise by showing construction clients the way to reduce capital costs and limit their exposure to price volatility and supply risks. All while developing a built environment that is better for people and the environment.
