Certificate or declaration by a suitably qualified competent person(s) that the as-built roof and walls comply with the requirements of Part L2. Architects and designers now need to take an integrated and holistic design approach to achieve regulatory compliance.

STEP 1 - DESIGN

6th Amendments: Conservation of Fuel & Power (Scotland)

Building Standards 1990 Part J

Part L2: 2002 Conservation of Energy includes four major changes to traditional insulated metal roofing and cladding.

The design will need to be based on a complete integrated system solution for roof and/or wall cladding. Kingspan can provide construction solutions and details to achieve regulatory compliance with U-values, thermal bridging, air leakage and insulation continuity to the approved standard suitable for the intended use of the building e.g. industrial, office, swimming pool, etc.

Enhanced Construction Details

Two sets of details have been produced to give the Building Designer flexibility within the calculation for the total building heat loss. The decision on the choice of standard or enhanced details is taken by the Building Designer and is determined from the total building heat loss methodology demonstrated on pages 10 & 11 of this guide. A mixture of both standard and enhanced details maybe required for some projects.

STEP 2 - BUILDING CONTROL APPLICATIONS Architects or designers have to calculate the a-value (alpha) for the building envelope to achieve compliance of a equal to or less than 0.10 or demonstrate compliance via the alternative trade off route. In order to make the a calculation, the architects or designers as competent person(s) will most likely need the assistance of the envelope system manufacturer to provide f and Y values for the roof and wall cladding design. Any changes to specification of the cladding after the a-value is calculated will mean that the value has to be recalculated. If the a-value is too high the design and/or products will have to be amended to achieve compliance.

STEP 3 - TENDER The architects or designers have to specify roof and wall cladding systems which can achieve compliance with the requirement to minimise heat loss at all junctions or thermal bridges. Detailed drawings should be provided for each part of the roof and wall system, including all junctions, penetrations, abutments, internal gutters, smoke vents, louvres, soakers, doors, windows, rooflights, curtain walling, brickwork and floor slab edge etc. Kingspan as a roof and wall system manufacturer provide a comprehensive package of details for which the f, Y and air leakage seals have been optimised for differing building uses.

pliance in 7 Steps STEP 4 - CONSTRUCTION The duties of competent person(s) may be carried out by the developer/main contractor from step 4 onwards. The competent person(s) will be responsible for ensuring that the approved design is built and that workmanship quality also achieves compliance. Should alternative roof and wall systems or products be substituted to that specified it is necessary that they are fully regulatory compliant. Kingspan’s construction details have been designed to be installer friendly and robust so that a high level of workmanship quality can be achieved combined with fast installation speed.

STEP 7 - CONTINUITY OF INSULATION Provide a declaration that appropriate design and installation has been carried out to achieve reasonable conformity. Alternatively carry out a thermographic survey by competent person to demonstrate that the insulation is reasonably continuous over the visible envelope of the building and that excessive thermal bridging is avoided. Note: Building Control should be asked to confirm in advance who they consider is competent to complete the various declarations required before the completion certificate is issued.

Failure to achieve regulatory compliance will result in project handover delays and subsequent rectification costs.

Building Heating Loss through Thermal Bridging Introduction The Amendments to Part L2 of the Building Regulations 2000 came into force on 1st April 2002. The amendments require that thermal bridges at junctions and around openings be minimised (Items 1.9). Two means of meeting this requirement are described. The first (Item 1.10) requires the use of standard robust “details and practices independently demonstrated as being satisfactory.” This option primarily applies to domestic type constructions. The second option (Item 1.11) is to prove compliance by calculation in accordance with BRE Information Paper IP 17/01 for which MCRMA Technical Report No 14 provides specific guidance for profiled metal roofing and cladding. Means of Proving Compliance A methodology for proving that an acceptable level of heat loss through thermal bridging in buildings has been achieved is contained within MCRMA Technical Paper 14. The methodology is based upon BRE Information Paper IP 17/01 – Assessing the Effects of Thermal Bridges at Junctions and Around Openings. The basic procedure for proving compliance is best shown using a typical worked example:

6m 60m 40m

STEP 2 The linear meterage of thermal bridge junctions within the external envelope of the building is then measured/calculated. These junctions include window/door jambs, eaves details, corner details, cill details etc. The linear meterage of each junction is then multiplied by a calculated Y value (measurement of linear thermal transmittance) for that specific junction. This provides the total heat loss through each junction type for the building. The losses for each junction are then added together to give the total heat loss through thermal bridge junctions within the building (Total B).

The calculation process which should be followed is as follows:

STEP 1 The total heat loss through each plane element in the external envelope (including the floor) of the building is calculated by multiplying the U-value of each element by the total square meterage (m2) of that element within the building. The heat loss for each element is then added together to provide the total heat loss for the plane elements of the building (Total A).

Length Y-value (m) (W/mK)

Detail Junction

Heat Loss 1.20 37.20 80.80 82.80 167.70 31.20 4.32 32.98 1.20 0.16 14.40 1.20 16.00 0.16 0.64 2.72 0.16 13.60 0.32 488.76

STEP 3 To achieve compliance, the total heat loss for the thermal bridge junctions (Total B) should be equal to or less than 10% of the total heat loss through the plane elements of the building (Total A). i.e Heat loss through thermal bridging (Total B) = must be less than 0.1 Heat loss through the plane elements (Total A) For the example above:

488.76 (Total B) 2224.8 (Total A)

= 0.22

Therefore the example building has failed to comply through this route as the total heat loss through the thermal bridges equals 22% of the total heat loss through the plain elements. If a building fails to comply two options exist:

11

Building Heating Loss through Thermal Bridging 1. Improvements can be made to the junction details to reduce the levels of heat losses until the 10% threshold is achieved. In some instances it may not be possible or economically viable to minimise the total additional heat losses through the thermal bridges to this level. This may be particularly true with some specific building uses (e.g. Warehouses or Industrial Units) and/or junction detail configurations. 2. Follow the alternative permitted means of compliance outlined below. Alternative Means of Proving Compliance BRE Information Paper 17/01 permits compliance to be proven via a trade off calculation (paragraph 5.4). This methodology can provide a significantly easier route to compliance for many buildings. If the building in question does not contain the full allowable percentage of rooflights (20%) and windows/personnel doors (15% in industrial/storage buildings or 40% in places of assembly/offices/ shops) and these allowances have not been traded off elsewhere, then they can be used as a trade off against heat losses at thermal bridge junctions to prove overall compliance. Additional improved thermal standards of envelope plane elements can also be traded off in this manner. As the Total B is greater than 10% of Total A in the example building, then the trade off route should be followed. The means of proving compliance via this route is as follows:

STEP 4 A further calculation for the plane element heat losses should be undertaken for a “notional building” of identical size and form but which contains the maximum permissible areas of windows/personnel doors and rooflights. The areas of opaque roof and wall elements require to be reduced to allow for the additional rooflight and window/personnel door areas within the notional building. e.g. If the actual building has a total roof area of 1000m2 with 10% rooflights it would break down into plane elemental areas of: 900m2 of roof @ U value of 0.25 100m2 of rooflights @ U value of 2.2 Total roof area =

1000m2

With the notional building, the areas of rooflights can be the maximum permitted 20%. Therefore the revised elemental areas would be: 800m2 of roof @ U value of 0.25 200m2 of rooflights @ U value of 2.2 Total roof area =

1000m2

A similar trade off would be undertaken for windows and personnel doors within the wall areas. The total heat losses for each element are then calculated and added together to provide the total plane element losses for the notional building. (Total C).

For the example building: Notional Building Element

Area (m2)

STEP 5 The total plane element heat loss in the notional building (Total C) is then multiplied by 1.1. This allows for the 10% additional heat loss permitted at thermal bridge junctions and provides the total allowable heat losses for the notional building (Total D). For the example building: Total Allowable Notional Losses (D) = 3013.57 x 1.1 = 3314.93

STEP 6 The total heat losses for the actual building are obtained by adding the heat loss through the plane elements (Total A) and the thermal bridge junctions (Total B). If A + B (total heat losses for the actual building) is less than Total D (allowable heat losses for the notional building) then compliance is proven. For the example building: As the total heat losses for the actual building [(A+B) = 2713.36] are less than the total allowable losses for notional building [(D) = 3314.93], the building has complied with the requirements of IP 17/01 and Part L2 of the Building Regulations. Conclusion In many industrial and commercial buildings, the thermal bridging at junctions will not require any significant level of improvement over existing practice in order to prove compliance with IP17/01. This will be particularly true where the areas of rooflights and personnel doors/windows are below the maximum permitted areas within the regulations. The risk of condensation formation at thermal bridges is potentially of greater importance and must be considered. The risk of condensation formation is related to the building use and the internal surface temperatures at details. The minimum surface temperatures at details are defined as ‘f’ factors. Generic building types have minimum ‘f’ factor requirements which are laid down in IP17/01 (See Table A, page 4). Care must be taken to ensure that the degree of thermal bridging present at a detail does not lead to an unacceptable ‘f’ factor for the building use.

Thermal Bridging & Heat Loss Calculation Example Parts L2 & J To illustrate the relative effect of different components, junctions and air leakage loss the following has to be considered at design stage:

•

Provide continuity of insulation at junctions, joints, penetrations and abutment interfaces.

• Prevent missing insulation or gaps. • Minimise thermal or cold bridges.

Part L2 Assess condensation and mould growth risk (surface temperature f-factor).

•

• Assess

impact of thermal bridging throughout the building envelope, calculate linear thermal transmissions - Y-value and calculation of whole building’s a-value).
