7. ab cd Working in partnership to secure a better quality of life for all PRESENT POLICY FRAMEWORK 2004 – PPS 22 ‘Renewable Energy’ 2007 – PPS 1 ‘ Planning and Climate Change’ – Supplement 30 April 2009 ?? – The South East Plan Local Development Frameworks

8. ab cd Working in partnership to secure a better quality of life for all HORSHAM POLICY LDF Core Strategy Policy CP 2 ‘Environmental Quality’ LDF General Development Control Policies Policy DC8 ‘Renewable Energy and Climate Change.’ This states :- a) Planning permission will only be granted for proposals which ensure that : - measures are incorporated that reduce the impact on climate change;and - wherever possible and certainly for any development of 10 or more dwellings and other forms of major development, sufficient on-site renewable energy equipment or other design measures are provided to achieve at least a 10% reduction in the scheme’s predicted carbon dioxide emissions.

9. ab cd Working in partnership to secure a better quality of life for all HORSHAM POLICY b) The Council will permit schemes for renewable energy ( eg solar, biomass, and energy crops, landfill gas and hydroelectricity ), where they do not have a significant adverse effect on landscape character, wildlife, areas of historical significance or amenity value.’ Renewables versus Sustainable Design and Construction.

10. ab cd Working in partnership to secure a better quality of life for all APPLICATION PROCESS Pre Application – examine policy and consider potential at the outset. Application – details in ‘energy statement’ or ‘design and access statement.’ Processing – ensure case officer is satisfied with the details. Committee – divergent member views Decision – conditions should be expected if permission is granted. - many authorities will specifically refuse permission if ‘renewables’ not addressed.

11. ab cd Working in partnership to secure a better quality of life for all EXAMPLES OF CONDITIONS – renewables London Borough of Merton No works in relation to the proposed development shall commence on site pursuant to the planning permission until details of a renewable energy generation system for the proposed….development which provides at least 10% of the predicted energy requirements have been submitted and approved by the local planning authority and suitably and operational to the satisfaction of the local planning authority prior to the occupation of the accommodation. London Borough of Enfield The development shall be carried out in accordance with the measures identified in the sustainability assessment form submitted on … ( and amendments received..). Before the development is first occupied, the developer shall submit to the LPA a statement confirming that the development hereby approved has been so carried out.

12. ab cd Working in partnership to secure a better quality of life for all EXAMPLES OF CONDITIONS – renewables Woking Borough Council Prior to the commencement of any development, details of predicted energy use of the development and the generation of on- site renewable energy shall be submitted and approved by the Local Planning Authority. These details will demonstrate how energy efficiency is being addressed, including bench mark data, and show the on-site measures to be taken to produce a minimum of 10 per cent of the total energy requirements of the new development by means of renewable energy sources. Such details as may be approved shall be implemented and retained in perpetuity.

13. ab cd Working in partnership to secure a better quality of life for all INSPECTORS CONDITION – code for sustainable homes. No development shall take place until an initial design stage assessment by an accredited assessor for the Code for Sustainable Homes has been carried out and an interim certificate has been submitted to and approved in writing by the local planning authority stating that each dwelling has been designed to achieve a minimum of Level 3 of the Code (or an equivalent level of performance if an alternative independently assessed means of sustainability assessment is used). No dwelling shall be occupied until a final certificate stating that the dwelling complies with a minimum of Level 3 of the code has been submitted to the local planning authority.

14. ab cd Working in partnership to secure a better quality of life for all FROM NOW ON More LDF’s with ‘Merton Rule’ policies More of those policies will be prescriptive and ‘require’ rather than ‘encourage’ The level at which the policy operates will reduce For the next speaker but The Code for Sustainable Homes requirements ( level 3 -2010, level 4 - 2013, and level 6 - 2016 ), are increasing, with level 5 requirements meaning that on site renewables are essential

27. Climate change and Building Control What does it have to do with us? David Starr

28. What do we have to say? Introduction. The position in which we find ourselves. The story so far. How the regulations have changed over the recent years. What we have seen. The way SAP, energy calculations, drainage and permeability design have been used. Better by design. Improvement on good design.

29. Introduction Changing emphasis, requirements and concerns. Horsham district council Climate change working group. Getting advice.

30. Introduction The Times January 29, 2009 Scepticism grows over the viability of green projects Robin Pagnamenta, Energy and Environment Editor Speaking on the sidelines of the World Economic Forum, Lord Turner, chairman of the Financial Services Authority (FSA) and of the Government’s Committee on Climate Change, said that the study was a response to mounting scepticism over the Government’s plans for a huge expansion of wind and tidal power. The Times March 26, 2009 When oil, coal and gas are cheap, who is going to throw their cash into the wind? Robin Pagnamenta, Energy and Environment Editor The credit crunch has undermined developers’ ability to borrow to fund big wind and solar power schemes, while tumbling prices for conventional fuels like oil, coal and gas have undermined the economics of the renewables industry. “Are we able to worry about more than one concern at a time”.

31. Can or does the country continue to think about the environment and environmental issues while the immediate economic situation looms large. The Guardian, Thursday 12 February 2009 Britain should prepare for massive loss of landmass, warn engineers UK should change building design, transport and energy infrastructure ahead of climate change and high sea levels Terry Macalister The climate change movement must be inclusive The climate change movement must broaden its social base from the white middle-classes to include the poor and ethnic minorities if it is to be successful in protecting the environment For weeks now the world has been mesmerised by the "credit crunch". But the biggest single long- term threat to all our futures remains the issue of climate change.climate change

32. Man’s effect or natural fluctuations. Temperatures set to rise. Climate change is casting its influence over the construction industry.

33. Sea level changes Weather conditions

34. What does this have to do with the building regulations.

35. The story so far. Building Regulations. Health and safety in use. 1985 regulations – conservation of fuel and power. by 1995

36. In 2002 changes add a requirement for information on boilers and there operation. (d) providing sufficient information with the heating and hot water services so that building occupiers can operate and maintain the services in such a manner as to use no more energy than is reasonable in the circumstances. Also at this stage control of replacement services and fittings was included.

37. 2006 edition the options were limited, removing the elemental approach. CO2 became the prime measure.

38. Checklist for dwellings. 5 Criteria. As built information.

39. Other parts of the regulations. Approved document F. Guidance notice-air permeability Approved document H. Section H3-surface water disposal

42. Changes to come Approved document G – Use of water. Approved document L – changes to align more closely with the code for sustainably homes. Approved document F – ventilation details. Approved document C – flood resilience.

43. What have we seen so far. I have a ‘Green design’ because I met the requirements of the building regulations. SAP calculations added at the end, not used as part of the design tools. Adjustment of the design to just meet the minimum requirement. Use of loopholes to justify design. Removal of elements of the design.

44. The use of high permeability figures in the DER/TER design.

45. Better by design. By linking the building regulations with the code for sustainable homes, using other guidance and manufactures design information, sustainable elements can be built in to your buildings that satisfies your clients needs the site limitations and the regulatory requirements. Future proofing.

46. Better by design. Orientation Natural and designed shading. Rainwater harvesting. Gray water capture. Foundation design. Flood protection. Whole life design.

47. How you can use the regulations. The regulations are not must does, they contain options. Remember that they are only the minimum standard to be achieved. Read the guidance notes the help to link the approved documents together.

48. In conclusion Government response to Climate change is putting pressure on the construction industry. Changing emphasis of the building regulations. Site specific design can help meet the regulations and code requirements. Use the code as part of your design tools. Adaptation and whole life design.

55. Rainwater Harvesting Presented by Phil Bradbury Environmental Wastewater Solutions

56. Introduction to WPL Limited WPL Ltd provide innovative and reliable wastewater treatment, rainwater harvesting and grease management systems for domestic, commercial and industrial markets Manufactures and Distributors of waste water treatment plants for the Domestic and Commercial & Industrial markets Distributors/Resellers of Domestic and Commercial Rainwater Harvesting Systems Framework supplier to most UK water utilities Over 25 years experience in Water & Waste Water Treatment Environmental Wastewater Solutions

57. Learning Objectives Understand what rainwater harvesting is Why use rainwater harvesting Design considerations What is available Installation Features & Benefits Cost Conclusion

58. Environmental Wastewater Solutions What is rainwater harvesting? Upto 50% of mains water that is currently used can be safely replaced with rainwater without any inconvenience to the customer. Properly designed rainwater harvesting systems are designed to provide sufficient water for a property to have 21 days water storage capacity and this reduces the potable water consumption to be significantly less than 80 litres per person per day thereby enabling an immediate 6 star rating within the Codes Water Category. Can be fitted in new and existing properties The collection of water for re-use from a roof or hard standing area. Uses: Toilet Flushing Washing Machines Cleaning Garden Car Wash

59. Environmental Wastewater Solutions Using rainwater harvesting for domestic and commercial buildings: As a result of the growing population water reserves are declining. The code for sustainable homes uses a ‘star’ system to demonstrate the overall sustainability of a home. A growing number of planners and developers’ customers are already asking for the design and construction to be at a 5 or 6 star rating. Key Benefits: Helps alleviate flood risks by collecting excess water. Due to erratic weather systems we either have an abundance or drought. Rainwater Harvesting is the only sustainable drainage system that removes the initial impact of storm water from the site. Any Development with over 10 houses must undertake a flood assessment. The E.A. accept rainwater harvesting as an appropriate form of surface water attenuation. Provides a source of usable water during periods of low rain fall. One of the easiest and inexpensive ways to achieve cost savings on water bill. Legislation bought in by the government in 2006 gave water companies the right to compulsorily meter all it’s customers, currently about 40% of the population have meters, but this will increase over time. The legislation aims at 90% within 10 years. Adds sustainable value to a property. Regulations SUstainable Drainage SystemsThe Building Act & Regulations Part H Drainage and Waste DisposalH3 Rainwater Drainage Part L Sustainable rainwater drainage Why choose rainwater harvesting?

60. Environmental Wastewater Solutions The Code for Sustainable Homes - Category 2: Water Over a number of years the Code for Sustainable Homes is introducing water reductions on a phased basis between public and private housing. The code aims: “ TO REDUCE THE CONSUMPTION OF POTABLE WATER IN THE HOME FROM ALL SOURCES, INCLUDING BORE HOLE WELL WATER, THROUGH THE USE OF WATER EFFICIENT FITTINGS, APPLIANCES AND WATER RECYCLING SYSTEMS” The use of dual flush toilets, aerated taps etc are commonplace within the code to achieve the lower code levels 1 & 2. Code levels 3 & 4 are already in place for public housing, and will be introduced to the private sector by 2010. To achieve this level you need smaller baths as well as the previous methods above, however these methods may prove to be unpopular to the house holder, primarily comfort and convenience. Rainwater harvesting is the most cost effective and practical way to achieve the code levels 5 & 6, which will be mandatory by 2013 for the Public sector and 2016 for the private sector. Code for Sustainable Homes Weightings: The weighting factor to percentage points contribution for the water category is 9%. With 6 credits available in the category, the weighted value of each credit is 1.50 – the highest of any category within the code.

66. Environmental Wastewater Solutions Installation Considerations Plumbing Legislation Type AA or AB Air gap WRAS dictates that pipes carrying non-potable water must be clearly marked WRAS recommend –Hazard assessments –Prevention of cross contamination –Screened Inlets –Insulation to minimise frost damage Maintenance Whilst filters are self cleaning, inspection 3 times per year is recommended Gutters need to be kept free of debris A visual inspection of the tank is required once a year Control systems should be checked once a year

67. Environmental Wastewater Solutions Water Quality No water quality standards exist for Rainwater Harvesting Studies done suggest the following as standards –Vehicle washing <10 total coliforms –Irrigation <1,000 total coliforms –WC Flushing <1,000 total coliforms –In microbiological tests, Harvested Rainwater had less than 10% of the above as total coliforms cfu/100ml Sources Of Contamination Asbestos – cement roofs Metal roofs can taint the water with leachates Bitumen or felt can cause odour Grass or other vegetation may cause soil and colour problems When not to use Do not collect from hard standing, animal contamination as well as oils from cars Should not be used for drinking or ingestion with out further treatment

68. Environmental Wastewater Solutions Benefits Other than filtering no further treatment required Compliance with building regulations Reduced loading on sewers Reduced water bills End User Perceptions The cost of systems are prohibitively expensive Concerns over water quality and health risks Costs The costs for systems vary but for a basic system they start at £1,500 up to £3,500. Installation costs vary from £300 up to £1,500

69. Environmental Wastewater Solutions Conclusions Relatively cheap attenuation for sites Customers will see a payback if on water meters Supply of water for the garden during hose pipe bans Ease of installation on new builds, more difficult on retrofits Compliance with new regulations and guide lines Sources Of Information WRAS Water Regulatory Advisory Scheme Web site – www.wras.co.ukwww.wras.co.uk –Specification for backflow prevention Environment Agency Web site – www.environment-agency.gov.ukwww.environment-agency.gov.uk Phone – 08708 506506
