1. Part L (England & Wales) 2010

1. 1 Introduction • The Government has announced a plan to gradually improve the energy efficiency of buildings • Significant changes for windows in 2010 • Responses to public consultation were submitted in September 2009 • Final Approved Documents were published on 30 th April 2010 with implementation 1 st October 2010 • Main changes and implications for your business and customers are summarised here

1. 2 Headline Changes • All new buildings have target of 25% reduction in Carbon Dioxide (CO 2) emissions compared to 2006 levels • Window Energy Ratings (WERs) will become the main compliance for replacement windows in homes • Alternative route retained for window U values • No change for conservatories • Increased focus on limiting solar gain in summer (reducing load on air-conditioning or need to install air conditioning) • Focus on solar control emphasised particularly for public and commercial buildings

1. 3 Windows in New Homes

1. 3 Windows in New Homes • Target of 25% reduction in CO 2 emissions over the 2006 level • Total is based on overall building efficiency through SAP calculation • No specific requirement for windows (other than “back stop” of window U value = 2. 0 W/m 2 K): Pilkington K Glass ™ and Pilkington energi. Kare ™ exceed requirements • Optimum combination of window g and U values will give best result in SAP – i. e. simply lowering the U value may result in worse overall performance • House Builders could use highly efficient windows to offset other costs • Using Pilkington K Glass ™ especially when combined with Pilkington Optiwhite ™ as in Pilkington energi. Kare ™ offers the ideal solution • Pilkington energi. Kare ™ Triple will provide the ultimate in energy efficiency forward looking housebuilders

1. 4 Replacement Windows in Homes

1. 4 Replacement Windows in Homes • Window Energy Rating (WER) band C minimum requirement for all windows and roof lights – – Alternative route – max window U value of 1. 6 W/m 2 K Where necessary to retain character of the building, centre pane U value of 1. 2 W/m 2 K for replacement windows or supplement single glazing with low e secondary glazing – Pilkington K Glass ™ ideal for the latter • Pilkington energi. Kare ™ will help window companies to comply or exceed requirements and go up to A rating • Window companies need to obtain a BFRC (or similar) rating – – Directly as Fabricator or through BFRC Authorised Retailer scheme Pilkington help and support available • Doors must have a maximum U value of 1. 8 W/m 2 K – Easily achieved using Pilkington K Glass ™ • Exemption for Listed buildings and those in conservation areas is more clearly defined – Pilkington energi. Kare ™ Legacy is the ideal solution where design constrained (or utilise Pilkington K Glass ™ in appropriate frames)

1. 4 Conservatories

1. 4 Conservatories • Small, domestic conservatories (<30 m 2) will not be introduced into Part L (as originally proposed) • Definition of Conservatory modified to add that the transparent / translucent material in external envelope is >150% floor area • Still allowable to use IGUs without low e glass – Pilkington K Glass ™ and Pilkington Activ ™ still deliver energy saving and comfort benefits to householder and ensuring a comfortable environment year round. • Reduce solar gain using solar control glass in the roofs and walls – Pilkington Activ ™ Blue or Pilkington Activ ™ Neutral • Progressive improvements in energy efficiency still expected in 2013 and 2016. Requirements for total energy performance may need to be considered in future

1. 5 New Non-Domestic Buildings

1. 5 New Non-Domestic Buildings • Target 25% reduction in CO 2 emissions compared with 2006 (including hotels) • Compliance demonstrated on the basis of CO 2 emissions using Government approved software SBEM • No tightening of the insulation requirement on windows Left unchanged i. e. window U value 2. 2 W/m 2 K – Pilkington K Glass ™ remains ideal cost effective solution – • Using SBEM, lowering U value not always the best way to achieve energy efficiency. In certain situations, solar gain will need to be controlled - the right glass choice will influence this – Range of products from the Pilkington Solar Control range meet all requirements • No limiting value on display windows such as ground floor shop windows, car showrooms and similar glazing

1. 6 Existing Non-Domestic Buildings

1. 6 Existing Non-Domestic Buildings • Maximum U value is 1. 8 W/m 2 K – – Pilkington K Glass™ will meet this U value requirement Where necessary to retain character of the building, centre pane U value of 1. 2 W/m 2 K for replacement windows or supplement single glazing with low-e secondary glazing – Pilkington K Glass ™ ideal for the latter • Doors with >50% glazed area must have a max U value of 1. 8 W/m 2 K – Pilkington K Glass ™ as the low-e pane provides ideal solution • If buildings are domestic in character (eg. care homes or student accommodation) the glazing requirements are the same as for domestic buildings – i. e. WER band C so Pilkington energi. Kare ™ is the natural choice • Increased emphasis on Solar Control in these types of buildings – Choice of products from the Pilkington Solar Control Glass range meet all requirements

2. Section 6 (Scotland) 2010

2. 1 Scotland 2010 Headlines • Significant reductions in target CO 2 emissions for all new buildings compared with current • Tighter elemental requirements for windows for replacements and extensions similar to England & Wales Higher standards apply where fabric of existing home is poor ie. pre-1983 Window Energy Ratings and U value are routes for compliance for replacements – Restrictions on centre pane U value option More conservatories fall into scope For non-domestic replacements, window U value only New Technical Handbook issued on 6 th April 2010 Implementation on 1 st October 2010 – • • •

2. 2 Key product implications for the Scotland Regulations Structure, timing & implications very similar to England & Wales • New Homes: 30% CO 2 improvement required – Pilkington energi. Kare™ remains ideal cost effective solution • Existing Homes: WER band C required as minimum – Pilkington energi. Kare™ enables windows to easily comply • Conservatories: 2. 0 W/m 2 K window U value required in all glazing – Easily achievable using Pilkington K Glass™ • Extensions to homes with poor fabric: WER band A or window U value 1. 6 W/m 2 K minimum requirement – Pilkington energi. Kare™ Plus enables windows to comply • New Non-Domestic Buildings: 30% CO 2 improvement required – – Pilkington K Glass™ remains ideal low-e solution for thermal insulation Pilkington Eclipse Advantage™, Pilkington Solar-E™ and Pilkington Activ™ Neutral offer wide choice to suit all applications • Existing Non-Domestic Buildings: Window U value 1. 6 W/m 2 K – Pilkington energi. Kare™ Plus provides effective solution

3. Summary • The Government has announced requirements to improve the energy efficiency of all buildings • Further changes planned for 2013 and beyond • Glazing has a pivotal role in meeting the challenges • Products from our wide range are suited to meet all future requirements • Pilkington K Glass™ and Pilkington energi. Kare™ range are ideal in the majority of applications • Solar control products such as Pilkington Activ™ Blue, Pilkington Suncool™ range and Pilkington Eclipse Advantage™ are increasingly important as solutions for energy efficient glazing

4. Action Planning • Domestic windows need to be registered with BFRC before October 2010 - don’t leave it too late – Check that your customers understand & are ready for the changes • Assistance through the Window Energy Rating approval process with BM Trada & Build. Check for Pilkington customers – For further details call the customer contact centre on 01744 692000 • Think about which products you will use for compliance in all building types and to meet possible requirements for solar control: New homes: Pilkington energi. Kare™ Existing homes: Pilkington energi. Kare™ Non-domestic: Pilkington K Glass™ & Pilkington solar control range

4. Action Planning Decide on glazing solution for Part L Warning! DEADLINE July October ACT NOW April Final Building Regulations published Ensure BFRC registration in place for domestic window supply route New Building Regulations implemented
