7. Application of Building Regulations to existing buildings (Refer to SI 497 of amended by SI 259 of 2008 and SI 513 of 2010)
1. No new or greater contravention Article 9(2) -no works shall be carried out to a building which would cause a new or greater contravention in the building of any provision of Building Regulations. 2. Material alterations, extensions and repair and renewals Art 11. Building Regulations apply to— (1) (a) the material alteration or extension of a building; and (b) every part of a building affected by works but only to the extent of prohibiting any works which would cause a new or greater contravention of any provision of the Regulations (2) “material alteration” means an alteration, where the work or part of the work carried out by itself would be the subject of a requirement of Part A (Structure), B (Fire) or M (Access and Use) of the Second Schedule to these Regulations. (3) These Regulations shall apply to any repair or renewal likely to affect the structural integrity of the building or building element being repaired or renewed. (4) Part L of the Second Schedule of these Regulations shall apply to renewal works to existing buildings involving the replacement of external doors, windows and rooflights (5) Part L of the Second Schedule to these Regulations shall not apply to works (including extensions) to an existing building which is a ‘protected structure’ or a ‘proposed protected structure’ within the meaning of the Planning and Development Act 2000 (No. 30 of 2000).”

3. Provision of services, fittings and equipment With regard to building services, Article 12 applies to all works in connection with the provision (by way of new work or replacement) in relation to a building of services, fittings and equipment where Parts G (Hygiene), H (Drainage and Waste Water Disposal) or J (Heat Producing Appliances) of the Second Schedule to the Building Regulations impose a requirement. 4. Material change of use Where a material change of use to a building takes place, Article 13(1) provides that the requirements of Parts A1 and A2 (Structure), Part B (Fire Safety), Part C4 (Site Preparation and Resistance to Moisture), Part E Sound, Part F (Ventilation), Part G (Hygiene), Part H (Drainage and Waste Water Disposal), Part J (Heat Producing Appliances), and Part L (Conservation of Fuel and Energy) apply to the building undergoing the change of use.

9. Building Control Regulations for existing buildings Refer to SI 496 of 1997 with amendments.
A commencement notice is required for:
The erection of a building
A material alteration of a building
An extension to a building
A material change of use of a building
Works in connection with the material alteration (excluding minor works) of a shop, office or industrial building where a Fire Safety Certificate is not required
A commencement notice is not required for works or a change of use which requires neither planning permission, nor a Fire Safety Certificate
Since 1st Mar 2014 works to existing buildings which require a fire safety certificate are subject to BCAR (assigned certifier, competent builder and submission of certificates of compliance on completion)

10. Building Control for existing buildings contd
Building Control for existing buildings contd. Refer to SI 496 of 1997 with amendments for legal interpretation
Fire Safety Certificates are required for works in connection with:
works in connection with the design and construction of a new building
works in connection with the material alteration of: A day centre, A building containing a flat, A hotel, hostel or guest building , An institutional building ,A place of assembly ,A shopping centre
works in connection with the material alteration of a shop, office or industrial building where additional floor area is being provided within the existing building or where the building is being sub divided into a number of units for separate occupancy. 
works in connection with the extension of a building by more than 25 square metres 
A building as regards which a material change of use takes place
to which the requirements of Part B apply
A building used as a dwelling other than a flat is exempt from the requirement for Fire Safety Certificates

11. Part D

12. Part L 2018 -Existing Dwellings
L2 For existing dwellings, the requirements of L1 shall be met by: (a) limiting heat loss and, where appropriate, maximising heat gain through the fabric of the building; (b) controlling, as appropriate, the output of the space heating and hot water systems; (c) limiting the heat loss from pipes, ducts and vessels used for the transport or storage of heated water or air; (d) providing that all oil and gas fired boilers installed as replacements in existing dwellings shall meet a minimum seasonal efficiency of 90 % where practicable. (e) when a building undergoes major renovation, the minimum energy performance requirement of the building or the renovated part thereof is upgraded in order to meet the cost optimal level of energy performance insofar as this is technically, functionally and economically feasible.

Notes:
1. The U-value includes the effect of unheated voids or other spaces.
2. For material alterations, the U-values relate to the new works.
3. For insulation of ground floors and exposed floors incorporating underfloor heating, see paragraph
4. This only applies in the case of a wall suitable for the installation of cavity insulation. Where this is not the case it should be treated as for “other walls”.
5. This U-value only applies where floors are being replaced.
6. For buildings of architectural or historical interests or permeable traditional construction, refer to paragaragh 0.6.

14. EPBD-Major Renovations
‘major renovation’ means the renovation of a building where more than 25 % of the surface of the building envelope undergoes renovation; Art. 7 “when buildings undergo major renovation, the energy performance of the building or the renovated part thereof is upgraded in order to meet minimum energy performance requirements set in accordance with Article 4 (cost optimal level) in so far as this is technically, functionally and economically feasible.” Major Renovations to apply in Part L Building Regulations for Buildings other than Dwellings in to apply from Jan Major Renovations planned to be introduced in Building Regulations for Dwellings in Q to apply from 1H 2019
