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

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

Name ________________Unit 6/P7 – Legislative Constraints• Legislative constraints = laws

and legislation that limit your project.

• Building Regulations• The materials selected must

meet fire regulations• The pitch of staircase cannot be

too steep.• You must provide fire exits on

commercial• Where drainage goes• Choice of insulation, eg

materials to meet minimum U-value

• HASAWA• Will limit the hours people work• Will limit who works on your

site = qualification• You must have all paperwork in

place

• CDM• Will control how you work at

height.• You must have CDM coordinator• Digging trench – using crane

• Town an Country Planning Act• Concerned about the visual

appearance• Will limit height• Will limit the use, eg

residential , commercial• Will limit the type of materials,

eg they may want you to use the same as is in the street.

• Tree Protection Order prevents you from cutting down certain trees

• Section 106• LPA may require you to provide

affordable housing.• LPA may require you to employ

young or local work force.
