1. Name ________________ Unit 6/P7 – Environmental Implications (what do developers need to take into account when building) Noise Nearby Residents Hours of work Council will enforce CO2 Emissions Plant machinery Transport of materials Construction Methods Prefab = less time on site Heavy weight = concrete = stores heat in thiick walls Lightweight = timber frame = quick = thermally efficient Destruction of Environment Perseveration of open space Greenbelt TPO’s Embedded Energy The amount of energy required to produce a material = extraction, processing, transport Pre-cast concrete = high Extraction and Manufacture Timber is sustainable – it will grow back. FSC = sustainable source Fossil Fuels Prime resource depletion Recycling vs Reusing Construction often includes the demolition of buildings Steel can be recycled Brick can be crushed for hardcore Separate skips = on site recycling

2. Name ________________ Unit 6/P7 – Code for Sustainable Homes Method of assessing homes Introduced 2006 Will be replaced in 2016 and incorporated into building regs Homes are rated 1-6 (6 = best) Measure by: Energy usage Operational energy Alternative energy – solar power – wind power – ground heat Water saving Low use appliances Re-use rainwater Materials What was the impact of the materials – extraction – processing – transport – embedded energy Waste Provision for recycling Garden compost Pollution Higher insulation = less energy usage Water Run Off How does the site deal with water run off – paved areas = more run off = flooding. Health and well being Natural light Sound insulation Privacy Accessibility Management Provide home user guide Design in security Reduced impact of construction Ecology Green space Roof top gardens
