1. Edexcel BTEC Level 2 Diploma in Construction Influencing Factors Unit 3 Sustainability in the Construction Industry

2. Edexcel BTEC Level 2 Diploma in Construction Aims Learning Outcome 4 Know how sustainable design and construction techniques are used to address environmental issues. http://www.edexcel.com/migrationdocume nts/BTEC%20Firsts%20from%202010/BF 021800-Firsts-Construction-Issue3.pdfhttp://www.edexcel.com/migrationdocume nts/BTEC%20Firsts%20from%202010/BF 021800-Firsts-Construction-Issue3.pdf

3. Edexcel BTEC Level 2 Diploma in Construction Objectives To identify four sustainable design and construction techniques (P7) To describe four sustainable design and construction techniques (P8) To evaluate one specific sustainable construction technique from each stage of the development project (planning, design and construction) (M3) justify the selection of an appropriate sustainable technique (D2)

4. Kingspan Lighthouse Watch the video and make a list of as many of the sustainability techniques as possible. http://www.youtube.com/watch?v=aDqCdWn xmQc Edexcel BTEC Level 2 Diploma in Construction Techniques

5. Boiler Biomass boiler The boiler provides hot water and space heating in winter, fuelled by wood pellets. It is located in the utility room to provide a dedicated drying area, as an alternative to the (electricity sapping) tumble dryer. Edexcel BTEC Level 2 Diploma in Construction

6. Photovoltaic (PV) array PV panels capture energy from the sun to supply electricity for the whole house. Any surplus is sold back to the grid. Edexcel BTEC Level 2 Diploma in Construction

7. Solar thermal panels The panels generate all the hot water in the summer and some in the spring and autumn, reducing the demand on the biomass boiler and the amount of wood used, keeping costs to a bare minimum. Edexcel BTEC Level 2 Diploma in Construction

8. Building envelope Utilising the Kingspan TEK wall system, the construction method provides the highest level of thermal efficiency and air tightness. This helps to provide a code 6 rating Edexcel BTEC Level 2 Diploma in Construction

9. Smart metering and monitoring systems A smart meter records energy consumption, to help occupants identify any wastage and to promote more environmentally aware lifestyles. Edexcel BTEC Level 2 Diploma in Construction

10. Ventilation The mechanical ventilation and passive system operates – the ‘wind catcher’ – that operates in tandem to provide flexible and effective ventilation. Edexcel BTEC Level 2 Diploma in Construction

11. Heating The building envelope specification will deliver high levels of thermal insulation and air-tightness so that the home will only need to be heated for a couple of months in mid- winter. Edexcel BTEC Level 2 Diploma in Construction

12. Reducing solar gain External shutters can be used in summer to reduce the build up of heat. Edexcel BTEC Level 2 Diploma in Construction They block out all direct sunlight.

13. Reduced glazing Complying with the U values of the Code, the glazing is 5 - 10% less than that in the traditional home. The living space is adapted to accommodate this with a large double height volume on the upper levels with sleeping accommodation below. Edexcel BTEC Level 2 Diploma in Construction

14. Air tightness Lobby areas designed to the front and back of the house maintain the high level of air-tightness in the build. Edexcel BTEC Level 2 Diploma in Construction

15. Water Increased awareness about what water to use where - rainwater for the garden and washing machine and used shower and bath water for the WC. An average saving of 50% compared to a conventional house. Edexcel BTEC Level 2 Diploma in Construction

16. Student Activity Techniques (P7)Description (P8) 1. 1. 1. 1. Edexcel BTEC Level 2 Diploma in Construction Identify four sustainable design and construction techniques that are used to minimise environmental impact. At least one example of design and one example of construction should be included among the four techniques. (P7). For the second part you must describe a minimum of two sustainable design and construction techniques that are used to minimise environmental impact. (P8)

17. Stages of the development process Edexcel BTEC Level 2 Diploma in Construction Sustainability techniques can be used at each stage of the project to address environmental issues. Planning can involve providing incentives to developers to incorporate sustainability, providing cycle and pedestrian zones, specifying the use of Brownfield sites, support from EU regeneration grants and monitoring of emissions. Design can involve incorporating sustainable designs, building orientation, green roof technology, rainwater harvesting and grey water systems, sourcing and specifying local materials, using zero carbon materials and alternative energy sources. Construction can involve using prefabrication units, module units and timber frame construction, minimising waste on site and reducing pollution landfill.

18. Factors influencing these stages Many factors influence the planning, design and construction of the project: Edexcel BTEC Level 2 Diploma in Construction StageFactorsImpact Planning Space available to develop. The local plan in which the council decides what will be built and where. Greenfield Or Brownfield site Costs of decontamination of ground. Government grants available historical nature of the site and surroundings Planning with regard to Brownfield sites Planning with regard to greenfield sites Design Costs of the initial sustainable design Legal constraints through planning, height, size, etc. Physical size of the site Aesthetic - if a building looks good it can lift an area and create further opportunities Visual impact depending on what the designer wants building to look like Materials specified by the designer Services and energy used in the design Construction The construction design and management regulations 2007 Construction costs needing to be within budget Sustainable construction techniques needing to be employed Waste management from construction operations Noise dust and waste disposal which can have an environmental impact on the local community Congestion of roads by construction traffic Use of non local resources adding to transport Use of greenfield sites

19. Your chosen technique here StageEvaluation (M3) Planning Design Construction Edexcel BTEC Level 2 Diploma in Construction Student Activity For the third part; chose one of the techniques above and evaluate its effectiveness in use when compared to the techniques it has replaced at each stage of the development project (planning, design and construction) (M3)

20. Student Activity Chose one sustainable technique from the Kingspan Lighthouse and justify the selection in terms of the environmental benefits in terms of both effectiveness in use and relative costs. (D2) Edexcel BTEC Level 2 Diploma in Construction
