9 9 Sustainability is Key Driver for Resource Efficiency

10 10 Resource Efficiency

11 11 Ellen Macarthur and the Circular Economy

12 12 Linear Economy Verses The Circular Economy

13 13 The Circular Economy - Restorative by Design

14 Life Cycle Assessment Extraction Landfill Reuse Disposal Waste Maintenance Transport 14 Use Construction

15 15 CIBSE and WRAP Join Forces

16 16 Low Carbon Construction - Risks of Focus on Operational Energy The IGT report recommends a whole life carbon appraisal. The risks of just considering operational energy include: It would otherwise be possible to count an energy saving product as a good thing when it consumes more energy in its manufacture than it can save over its working lifetime that there is less pressure to reduce the high levels of materials waste in the industry that unnecessary increases in carbon emissions may be created by demolishing and replacing a building, where the carbon benefit of recycling existing structures is not taken into account. The IGT report on Low Carbon Construction

17 17 Government Policy improving our understanding of design approaches, including passive design, to balance energy demand and supply in the built environment is vital in enabling the industry to design and construct high performance, resource efficient buildings. The Government s Industry Strategy: Construction 2025

18 18 Drivers for Resource Efficiency The drivers for resource efficiency of building are to: reduce capital costs, price volatility and project risk, and help to provide a hedge against future risks of material shortages reduce the running costs by reducing the resources required to maintain and upgrade equipment demonstrate compliance with regulations and standards address the project brief or tender requirements.

19 19 Defining Resource Efficiency Resource-efficient building services make the best use of materials, water and energy over the lifecycle of the plant and equipment. This includes: Reducing materials consumption and wastage; Increasing reuse and recycled content, and enabling reuse and recyclability at end of life; Using resources with no scarcity and source security issues; Using products with lower embodied carbon and embodied water; Reducing energy and water use during construction; Designing for deconstruction, and Enabling energy efficiency and water efficiency in use. Adapted from WRAP definition of resource efficient construction

20 20 Aims of Project Resource efficiency in building services sector Engage with the industry to identify the barriers, challenges and opportunities. Set out how to deliver improvements in practice Improve awareness of opportunities & business benefits Produce a CIBSE guide on resource efficiency The opportunities in heating, cooling, ventilation, lighting and vertical transportation

26 26 Construction Materials From Cradle to Grave

27 Environmental Impacts - Pressure to Extract in sensitive environments Aggregate quarry in Malaysian Jungle 27 in unsafe conditions Marble quarry in China

28 28 Fiscal Measures - Landfill Tax There are two rates of Landfill Tax a standard rate for active wastes, 72 per tonne and a lower rate of 2.50 per tonne for inactive or inert waste such as rocks and soil HMRC checked on 22/7/14

29 Fiscal Measures - Aggregates Levy The Aggregates Levy was introduced in This encourages recycling and the efficient and sustainable extraction and use of an important natural resource by charging 2.00 per tonne for sand, gravel and rocks subjected to commercial exploitation in the UK. The Aggregates Levy is the most frequently given reason for the expanding recycled aggregates businesses since How much you pay You pay tax of 2 per tonne of sand, gravel or rock. You pay less on smaller amounts. For example, you d pay 1 on half a tonne. You still pay tax if you import the materials. 29 HMRC checked on 22/7/14
