BUILDING REGULATIONS 2013 (Starting in 2014- but may not have started construction until 2015!)

The newly introducted Building Regulations has seen a vast change in Fabric First- On most projects I would say that there is always a possibility of using a 100mm Cavity in a Tradtional Brick and Block Wall to achieve the Fabric Energy Efficiency (TFEE) compliance with Part L 2013.

There is always a case to consider building to the higher energy efficiency levels in Part L- but we would also highlight any potential cost of 

BUILDING REGULATIONS 2010

Green Heat Ltd - The Energy Efficiency Company are uniquely placed to help assist through Parts AD L1a L1b L2a and L2b.

Soince 1990 we have been calculating Carbon, finding energy efficienct solutions for achieveing complaince with the building regulations, and some newly intorduced planning conditions- such as the Merton Rule 10% or the London Major's Plan. 

BUILDING REGULATIONS 2002

Following extensive research, involving consultation with industry and environmental specialists, the Department of the Environment, Transport and the Regions (DETR) published, in March 2001, a draft of the revised Part L1 of the Building Regulations (Conservation of Fuel and Power).

This draft was made law in September 2001 and subsequently came into effect in April 2002. The amendments to Part L1 impact on the construction industry by introducing new methods of compliance with the ultimate aim of reducing the emissions of greenhouse gases caused in particular by carbon dioxide, a by-product of the combustion of fossil fuels.

Similar regulations apply in Scotland (Part J) and Northern Ireland (Part F).
There are three methods to demonstrate compliance:

    Elemental method
    Target method
    Carbon index

NEW BUILDING REGULATIONS REQUIREMENTS

These new regulations use SAP2005 as the only method to demonstrate compliance.

New Dwellings Approved Document L1A 2006

To implement the legislation of the EPBD there is now a requirement to use a whole house compliance method. All new dwellings at the planning stage will have to demonstrate that an acceptable carbon dioxide emission rate will be achieved. A Target Carbon Dioxide Emission Rate (TER) has to be calculated within the Standard Assessment Procedure (SAP).

This will be based on a notional dwelling built to the 2002 standards with a target reduction of 20%. The actual Dwelling Carbon Dioxide Emission Rate (DER) must then be no worse than the TER. The new SAP 2005 incorporates all these calculations.

On completion of the dwelling an Energy Performance Certificate must be produced based on the actual construction, incorporating any changes to the performance of the fabric or services between design and construction.

In essence this will mean lower U values, higher boiler efficiencies and the integration of renewable energy with a certain degree of flexibility for designers.

There are limits on heat loss through the fabric of the dwelling, on excessive solar gain and heat gains/losses from pipes, ducts and vessels used for space heating, cooling and hot water. There is a requirement to provide energy efficient and properly commissioned heating and hot water services and provide the owner/user enough information so the dwelling and its services can be operated at their full potential.

The new Regulations make reference to the Domestic Heating Compliance Guide. This has been developed by Government with the Heating Industry and covers all aspects of domestic heating including gas, oil, solid fuel, hot water, solar thermal, under-floor heating, combined heat and power and heat pumps. As the title states this will indicate how to ensure your heating and hot water systems comply with the requirements of the Regulations. The minimum efficiency for gas boilers is 86% and oil is 85% (until 2007) as introduced in the April 2005 revision to Part L.

There is also now a requirement for post construction air pressure testing to be carried out on a sample of each dwelling type and remedial measures undertaken if they fail.

Existing dwellings Approved Document L1B 2006

The nature of building work on existing dwellings requires a more elemental approach and accordingly controlled elements have U value targets set at 0.3 for walls; 0.16 for roofs (0.2 for slope) and 0.22 for floors.

Replacement windows and doors are controlled fittings and windows should have a minimum U value of 1.8 and glazed doors 2.2

Controlled services remain similar to the existing regulations with further details provided in the Domestic Heating Compliance Guide. New and replacement gas boilers must have minimum efficiency of 86% (SEDBUK Band B) with limited exceptions, assessed as described in the Guide to Condensing Boiler Installation Assessment for Dwellings. Oil boilers must have a minimum efficiency of 85% (until 2007). There are also now minimum efficiencies for solid fuel boilers and individual heating appliances and a requirement for:

    Cleansing and water treatment for wet central heating systems
    Commissioning certificate to confirm completion
    Provision of information: provision of a suitable set of operating and maintenance instructions
    Minimum standard for hot water cylinders
    Minimum standard for heating and hot water controls

There is also a requirement for the provision of low energy lighting internally and externally Controlled services, elements and fittings are subject to Building Control inspection and a Building Notice will normally have to be provided. An alternative to this is for the work to be self certified by a suitably qualified competent person who has registered with a self certification body, such as CORGI for gas boilers, OFTEC for oil boilers and FENSA for windows.

The specifics are quite involved and complex and to meet the need of explaining these changes in greater detail a series of affordable value for money half day seminars have been arranged at convenient locations throughout England & Wales using material supplied by the Department of Communities and Local Government (DCLG).
