Part L Where are we heading?
![Page 3: CREAConstructionEvent: PartL changes](https://reader033.fdocuments.us/reader033/viewer/2022042814/5557ae1ed8b42a4a5d8b4f62/html5/thumbnails/3.jpg)
The Government has confirmed that from
2016 all new homes coming through the planning system must be built to a
zero carbon standard
and from 2019 all new non- domestic buildings must follow suit

How are we getting there?

What is next?
• 2013 regulations are a step on the way to full zero carbon compliance by 2016

To achieve zero carbon certain Allowable Solutionswill be required to produce renewable energy,
![Page 11: CREAConstructionEvent: PartL changes](https://reader033.fdocuments.us/reader033/viewer/2022042814/5557ae1ed8b42a4a5d8b4f62/html5/thumbnails/11.jpg)
Two optionsRoute A Local Planning Authority to develop policy using Third party providerOr Community Energy Fund. List of solutions and £ per tonne for carbon abatement Route B Private Energy FundVerification and Certification Scheme (ASVCS) to show investment will achieve carbon reductionAllowable Solutions Fund Holding to provide secure ”bank”

Issues
Achieving Cost effective energy efficiency measures
Gap between design standards and built performanceLack of sufficient performance dataExisting stockFuel Factor ideally removed for Zero Carbon standard
Robust Calculation methodology
![Page 37: CREAConstructionEvent: PartL changes](https://reader033.fdocuments.us/reader033/viewer/2022042814/5557ae1ed8b42a4a5d8b4f62/html5/thumbnails/37.jpg)
Performance gap
• Energy use/emissions 60-120% worse than predictions
• Why?• Lack of Knowledge
• • Willful or inadvertent deviation • Build quality• SAP shortcomings• Occupancy behaviour

HMG intend to provide
• Regulation specific training programmes:Testing and evaluation skills development programmes
• Wider education and training programmes
• R+D how buildings actually perform• PAS Publicly Available Specification• Robust National Calculation Methodology• Quality Assurance process

Things to do
• Analyse thermal performance very early in design process
• Design buildings as integrated low energy systems
• Learn from Passivhaus for fabric design and construction
• Improve infiltration rates• Upgrade existing buildings carefully
