Diwygiadau i'r Rheoliadau Adeiladu.

Ym mis Gorffennaf cyhoeddais nifer o bolisïau'r Llywodraeth mewn perthynas â thai yng Nghymru, gan gynnwys fy mwriad i'w gwneud yn ofynnol i leihau allyriadau nwyon tŷ gwydr mewn tai newydd o 8% (yn erbyn safonau 2010\).  Un elfen yw hon o'm hadolygiad o Ran L o'r Rheoliadau Adeiladu.  Heddiw, rwy'n falch o gyhoeddi fy amcanion llawn ar gyfer arbed ynni ym mhob adeilad yng Nghymru.

Tai sydd eisoes yn bodoli

Adeiladau sydd eisoes yn bodoli yw mwyafrif y tai yng Nghymru, ac mae mynd i'r afael ag allyriadau'r adeiladau hyn yn mynd i effeithio'n fawr iawn ar ein gallu i leihau ein hallyriadau carbon.  Fel rhan o'r adolygiad Rheoliadau Adeiladu, rwy'n mynd i gyflwyno nifer o newidiadau isel o ran cost i adeiladau sydd eisoes yn bodoli wrth eu hadnewyddu neu adeiladu estyniad. Bydd hyn yn helpu perchnogion i gadw costau gwresogi eu hadeiladau dan reolaeth wrth wella cartrefi yng Nghymru.  

Bydd Rhan L yn ei gwneud yn ofynnol i bob perchennog cartref sy'n adeiladu estyniad neu'n gwneud gwaith adnewyddu, fel addasu llofft neu'r garej, fodloni safonau deunyddiau gwell ar gyfer waliau, toeon a lloriau, tra bod y safon ar gyfer ffenestri yn aros fel y mae.  Hefyd byddwn yn gofyn am welliannau arbed ynni 'canlyniadol' i'r adeilad gwreiddiol.

Byddai'r gwelliannau hyn wedi'u seilio ar dair elfen gost effeithiol lle bo'n briodol:  


* Isafswm safon inswleiddio atig;
* Inswleiddio wal geudod;
* Isafswm safon inswleiddio tanc dŵr poeth.

  
Hefyd rwy'n cynnig cyflwyno gofynion ychwanegol, sy'n dweud na ddylid gwresogi nac oeri ystafelloedd haul os ydynt i gael eu hesemptio o'r Rheoliadau Adeiladu. Os bydd ystafell haul yn cael ei gwresogi neu oeri, bydd angen cydymffurfio â’r gofynion perthnasol o ran deunyddiau a gwasanaethau adeiladu.

Adeiladau Annomestig

Mae'r amgylchedd adeiledig yn golygu mwy na thai yn unig, ac mae adeiladau annomestig yn gwneud cyfraniad mawr at yr allyriadau carbon.  Mae'r llefydd yr ydym yn gweithio ac yn ymweld â nhw; swyddfeydd, ffatrïoedd, stordai, ysgolion, ysbytai a siopau er enghraifft, oll yn cyfrannu at allyriadau carbon Cymru ac yn gyfrifol am tua 21% o holl allyriadau nwyon tŷ gwydr Cymru. Mae'n amlwg bod gwella perfformiad adeiladau annomestig yn rhan bwysig o'r gwaith o arbed ynni a chyrraedd targedau yn ymwneud â newid yn yr hinsawdd yng Nghymru.

Ar gyfer adeiladau annomestig newydd, gan gynnwys ysgolion ac adeiladau iechyd, rwy'n cynnig 20% o ostyngiad mewn allyriadau nwyon tŷ gwydr o ofynion Rhan L 2010\.  Bydd hyn yn digwydd drwy gymysgedd o well deunyddiau a safonau gwasanaethau adeiladu, ac mae'n debygol y bydd angen technolegau ynni adnewyddadwy fel paneli solar mewn nifer o sefyllfaoedd.  

Rwy'n cydnabod bod 'annomestig' yn cwmpasu nifer o wahanol fathau o adeiladau, â phatrwm cymhleth ac amrywiol o ran defnydd o ynni. Hefyd rwy'n cydnabod bod tipyn o amrywiaeth yng ngallu gwahanol fathau o adeiladau i ostwng y defnydd ynni sydd dan eu rheolaeth. Felly rwy'n bwriadu parhau gyda'r arddull gyffredinol bresennol, sy'n gosod targedau mewn perthynas â'r defnydd o ynni mewn gwahanol fathau o adeiladau.

Seiliwyd y newidiadau arfaethedig hyn ar ymgynghoriad cynharach, ac fe gafwyd cefnogaeth y diwydiant. Bydd hyn yn golygu sicrwydd yn y tymor hir mewn perthynas â safonau deunyddiau ar gyfer adeiladau annomestig, a bydd hefyd yn helpu i gefnogi'r defnydd o dechnolegau amgen.

Fel adeiladau domestig, bydd gofyn i estyniadau annomestig fodloni gwell safonau ar gyfer waliau a thoeon, tra bydd safonau ffenestri a drysau yn parhau i fod ar yr un lefel. Bydd y gofynion ychwanegol na ddylai ystafelloedd haul gael eu gwresogi na'u hoeri hefyd yn berthnasol i adeiladau annomestig. Rwyf hefyd yn newid y Rheoliadau Adeiladu i'w gwneud yn ofynnol i bob estyniad annomestig, beth bynnag eu maint, wario o leiaf 10% o gost y prif waith, lle bo'n ymarferol, ar welliannau canlyniadol i'r rhan o'r adeilad sydd eisoes yn bodoli.  

Syniadau ar gyfer y dyfodol

Hefyd rwyf wedi ymrwymo i adolygiad pellach o Ran L o'r Rheoliadau Adeiladu yn 2016, er mwyn gosod y gofynion angenrheidiol i gydymffurfio â'r Gyfarwyddeb Ewropeaidd i bob adeilad newydd fod bron yn niwtral o ran defnydd ynni erbyn 2019 a 2021\.

**Building Regulations Amendments**


In July I announced a number of Government policies in relation to housing in Wales, which included my intentions to set the requirement to reduce greenhouse gas emissions for new homes by 8% (against 2010 standards).  This is only one element of my review of Part L of the Building Regulations.  Today I am pleased to announce my full intentions for improving the energy efficiency of all buildings in Wales.


**Existing Homes**


Existing buildings make\-up the majority of homes in Wales and tackling emissions from these buildings is going to have a huge impact on our ability in Wales reduce our carbon emissions.  As part of the review of Building Regulations I am going to introduce a number of low cost changes to existing buildings when they undergo renovation or extension. These will help home owners keep the costs of heating their buildings down whilst improving homes in Wales.  


Part L will require all homeowners undertaking extensions or improvements such as a loft or garage conversion to meet improved fabric standards for walls, roofs and floors, whilst windows will remain at the current standard.  In addition we will also require ‘consequential’ energy efficiency improvements to the original building.


These improvements would be based on three cost effective solutions where suitable:


* Minimum standard of loft insulation;
* Cavity wall insulation; and
* Minimum standard of hot water cylinder insulation


 


 


I also propose to introduce additional requirements that conservatories should not be heated or cooled if they are to be considered exempt from the Building Regulations. If a conservatory is heated or cooled then the relevant fabric and fixed building services requirements will apply.


**Non Domestic Buildings**


The built environment doesn’t just cover homes, non domestic buildings make a sizeable contribution to carbon emissions.  The places where we work and visit; offices, factories, warehouses, schools, hospitals and shops for example all contribute to Wales’ carbon emissions and account for approximately 21% of all greenhouse gas emissions in Wales and it is clear that improving the performance of non domestic buildings play a key part in achieving energy efficiency and climate change goals in Wales.


For new non domestic buildings, including schools and health buildings, I propose a 20% reduction in greenhouse gas emissions from 2010 Part L requirements.  This will be achieved through a mixture of improved fabric and building services standards and is likely in many situations to require renewable technologies such as solar panels.  


I recognise that ‘non domestic’ covers a wide range of building types and uses with a varied and complex proportion and distribution of energy use. I also acknowledge that the capacity of different building types and forms to reduce regulated energy is equally varied. I therefore intend to continue with the current aggregate approach by which targets are set in relation to energy use of different building types and uses.


The intended changes which were largely the basis of our earlier consultation received support from the industry and will allow a long term period of certainty in relation to fabric standards for non domestic buildings and will also help to support the use of alternative technologies


As with domestic buildings, non domestic extensions will be required to meet improved standards for walls and roofs, whilst window and door standards will remain at the same level,  similarly the additional requirements that conservatories should not be heated or cooled will also apply to non domestic buildings. I am also changing the Building Regulations to require all non domestic extensions, regardless of size, to spend, where practical, a minimum of 10% of the cost of the main work on consequential improvements to the existing part of the building.  


**Future thinking**


I am also committed to a further review of Part L of the Building Regulations in 2016, in order to set the requirements necessary to comply with the European Directive for all new buildings to be nearly zero energy by 2019 and 2021\.
