12 Ripon Grove, Elsternwick Section J Report – Performance Solution

1 EXECUTIVE SUMMARY The following report has been prepared to demonstrate compliance of the proposed Class 4/5 development at 12 Ripon Grove, Elsternwick. The proposed development is a fitout of an existing building for residential occupancy and adjoining office space, with minimal works to be done to the existing building fabric. Due to the scale and nature of the development, a performance solution assessment using House energy rating software specified in the BCA is deemed unsuitable for this development. Therefore, a performance solution using JV3 methodology has been used to show compliance as per the building surveyor’s request. Sections J1-J2 have been assessed using the JV3 verification method of assessment, which requires a reference case building, based on NCC 2016 Section J Deemed-to-Satisfy (DtS) provisions, to be compared against the proposed building to determine the comparative difference between the energy consumption of the two models. The following table shows the assessed areas and associated BCA building class and Verification Method. Building/Area

2 INTRODUCTION Sections J1-J3 have been assessed using a Performance Solution Method of Assessment. This method of assessment allows the benefits of the passive thermal design attributes of the development to be used to determine the most energy efficient and aesthetically pleasing glazing to be selected. The assessment requires a reference case building to be modelled, based on NCC 2016 Section J Deemed-toSatisfy (DtS) provisions, which is then compared against the proposed building (with the proposed glazing and insulation) to determine the comparative difference between the energy consumption of the two models. Results from the dynamic thermal and energy modelling are detailed below. As the proposed buildings when modelled with the DtS services consumed less energy annually than the reference building, compliance has been confirmed. For the purpose of this assessment it is conservatively assumed that the lighting and HVAC equipment perform at the minimum DtS performance efficiencies. Compliance is subject to confirmation from the contractor that all as-installed details pertaining to the thermal performance and energy efficiency of the building are within the performance requirements as detailed in this report. It is the responsibility of the contractor, architect and building surveyor to ensure the final construction incorporates a compliant solution.

12 Ripon Grove, Elsternwick Section J Report – Performance Solution

3 SECTION J COMPLIANCE REQUIREMENTS The proposed building information below has been taken from current architectural drawings. Performance parameters noted for the proposed building below must be included within construction documentation in order to achieve JV3 compliance.

3.1 REGULATION 233 – PARTIAL COMPLIANCE Regulation 233 of the Building Regulations 2018 applies to alterations to an existing building and requires that building work to alter an existing building must comply with the stated requirements. The Regulations describe an alteration as either: • •

An alteration to an existing building, e.g., internal alterations, relining of walls, relocation or removal of internal walls, replacing windows and doors or external cladding, and/or An extension to an existing building, i.e., increasing the size, adding on to the existing building.

Subject to the approval of the Registered Building Surveyor, we recommend that partial compliance with respect to the alterations be awarded based on what is deemed “reasonable”. Only minor works and modifications to the existing building fabric are proposed, as most of the alteration work is to be internal; with external masonry walls to be retained. The alterations to the building fabric include replacing ceiling lining in areas, and replacing some external glazing.

3.2 SECTION J1: BUILDING FABRIC Part J1 of the NCC lists the required thermal insulation properties that the new elements of the building envelope must meet. The building envelope is considered to be the parts of the building fabric which separates conditioned from non-conditioned spaces. This includes walls, roofs, ceilings, floors, slabs etc. 3.2.1 Thermal Construction – General Where required, insulation must comply with AS/NZS 4859.1 and be installed so that it: Abuts or overlaps adjoining insulation other than at supporting members such as studs, noggins, joists, furring channels and the like where the insulation must be against the member; and Forms a continuous barrier with ceilings, walls, bulkheads, floors or the like that inherently contribute to the thermal barrier; and Does not affect the safe or effective operation of a service or fitting. Where required, reflective insulation must be installed with: The necessary airspace to achieve the required R-Value between a reflective side of the reflective insulation and a building lining or cladding; and The reflective insulation closely fitted against any penetration, door or window opening; and The reflective insulation adequately supported by framing members; and Each adjoining sheet of roll membrane being – - Overlapped not less than 50 mm; or - Taped together.

Page 8 of 25

REVISION: 05 DATE: 14 August 2019


12 Ripon Grove, Elsternwick Section J Report – Performance Solution

Where required, bulk insulation must be installed so that: It maintains its position and thickness, other than where it is compressed between cladding and supporting members, water pipes, electrical cabling or the like; and In a ceiling, where there is no bulk insulation or reflective insulation in the wall beneath, it overlaps the wall by not less than 50 mm. 3.2.2 Building Fabric and Insulation The thermal performance requirements for all new external and internal walls (or where works are being done to existing walls) forming part of the building envelope are detailed below. Building Element External/Internal Walls As noted in Appendix D

Thermal Insulation Requirement

Minimum Total Construction R-value

Minimum R2.5 bulk or board insulation

R2.8

All in-fill walls will be constructed to match the thermal performance of existing walls forming the building fabric. This includes meeting the insulation levels (if any) of the existing walls. Any additional insulation beyond this level will not offer any benefit or improvement in overall thermal performance due to the negligible area of new in-fill walls compared to existing walls. There are no new floor areas forming the building fabric, nor work being done to existing floor areas. All new roofs/ceilings (or existing roof/ceiling areas where works are being done) that form part of the building envelope must achieve a minimum total construction R-Value as specified in Table J1.3a of the BCA. Where, for operational or safety reasons associated with exhaust fans, flues or recessed downlights, the area of the required ceiling is reduced, the loss of the insulation must be compensated for by increasing the R-value of the insulation in the remainder of the ceiling in accordance with Table J1.3b (refer to Appendix C: Table J1.3B). Thermal Insulation Requirement

Minimum Total Construction R-value

Level 01/Level 02 ceiling/roof As noted in Appendix D

Minimum R3.0 bulk or board insulation

R3.2

Ground/Level 01 ceiling As noted in Appendix D

Minimum R2.5 bulk or board insulation

R2.7

Building Element

Refer to Appendix D: Wall and Roof Insulation Loations for the exact locations where insulation has been required.

3.3 SECTION J2: GLAZING Performance requirements for the new windows on the building have been provided below. If alternative glazing is used, it must have equal or better performance values than those listed.

Page 9 of 25

REVISION: 05 DATE: 14 August 2019


12 Ripon Grove, Elsternwick Section J Report – Performance Solution

Window Type New external glazing

Typical Glazing Type Single glazed (clear)*

Whole Window System Performance U-value

SHGC

≤ 5.5

0.60 ± 10%

*Typical glazing type provided for reference only, glazing selection must meet minimum performance parameters. All glazing or window performance parameters refer to the AFRC whole of window performance, including the effect of the frame and the glass. Should alternative glazing be sought, the whole of window U-Value must be equal to or lower than the energy rating software value and the whole of window SHGC value must be within ±10% of that specified above. Glazing Disclaimer: The currently assessed window and glazing specifications detailed above are performance-based nominations only. It is the architect and contractor’s responsibility to ensure that the final product selections comply with these performance criteria. The contractor must engage a façade specialist or the window supplier to provide AFRC testing data to confirm that the window performance criteria noted above are satisfied for all external glazed elements. If glazing U-values is increased or the SHGC values are changed by more than 10%, selections should be reassessed by this office. Our advice relating to glazing selection is performance based. The performance criteria considered are those which affect NCC-BCA Section J compliance, i.e. U-value and SHGC only. The ESD performance requirements provided should be presented to a manufacturer along with installation details and details of other performance requirements (e.g. structural, acoustic) to determine a suitable glazing specification.

3.4 SECTION J3: BUILDING SEALING Building sealing requirements do not affect the JV3 modelling inputs. Part J3 requirements relevant to the currently proposed design are outlined below and must be demonstrated by the contractor. Windows and Doors All edges of new external windows should be fitted with a seal to restrict air infiltration. New external swing doors (except fire and smoke doors) must be fitted with a draft protection device on the bottom edge and seals to restrict air infiltration on the other three edges. For all other edges of new openable doors this can be a foam or rubber compression strip, fibrous seal or the like. Part J3 typically also requires all entrance doors that do not lead into an airlock to be self-closing or to be a revolving door. This requirement is in place in order to minimise air loss due to frequent opening of doors. As this development will effectively function as a Class 1 building and will be occupied as such, it is expected that entrance doors will only be opened and closed by occupants as required. Due to security and privacy interests, entrance doors will not be left open. Subject to the approval of the Registered Building Surveyor, we recommend that exemption from this requirement be awarded based on what is deemed “reasonable”.

Page 10 of 25

REVISION: 05 DATE: 14 August 2019


12 Ripon Grove, Elsternwick Section J Report – Performance Solution

Exhaust Fans All miscellaneous exhaust fans must be fitted with a self-closing damper or the like. For this development compliance should be covered by the mechanical engineer’s design and signoff. Construction of Roofs, Walls and Floors Roofs, ceilings, walls, floors and any opening such as a window frame, door frame roof light frame or the like located on the external fabric must be constructed to minimise air leakage. Therefore, they must be either: • Enclosed by internal lining systems that are close fitting at ceiling, wall and floor junctions; or • Sealed by caulking, skirting, architraves, cornices or the like. Evaporative Coolers All evaporative coolers must be fitted with a self-closing damper or the like. For this development compliance should be covered by the mechanical engineer’s design and signoff.

3.5 SECTION J4: MOVEMENT This section of the NCC has been deleted and no longer applies.

3.6 SECTION J5: AIR-CONDITIONING AND VENTILATION SYSTEMS NJM has provided a design compliant with the Section J5 requirements. A report to the building surveyor detailing our calculations has been provided as an appendix to this document. Refer to Appendix E: Section J5 – Compliance Checklist.

3.7 SECTION J6: ARTIFICIAL LIGHTING AND POWER NJM has provided a design compliant with the Section J6 requirements. A report to the building surveyor detailing our calculations has been provided as an appendix to this document. Refer to Appendix F: Section J6 – Artificial Lighting and Power.

3.8 SECTION J7: HEATED WATER SUPPLY AND SWIMMING POOL AND SPA POOL PLANT A heated water supply system for food preparation and sanitary purposes must be designed and installed in accordance with Part B2 of NCC Volume Three – Plumbing Code of Australia. The requirements of Section J7 apply to swimming pools – defined by the NCC 2016 Volume One as any excavation or structure containing water and principally used for swimming, wading, paddling, or the like, including a bathing or wading pool. These requirements therefore do not apply to the planted area of the natural pool. (a) Heating for a swimming pool must be by – (i) A solar heater not boosted by electric resistance heating; or (ii) A heater using reclaimed energy; or (iii) A gas heater; or (iv) A heat pump; or (v) A combination of (i) to (iv) (b) Where some or all of the heating required by (a) is by a gas heater or a heat pump, the swimming pool must have – (i) A cover unless located in a conditioned space; and (ii) A time switch in accordance with Specification J6 to control the operation of the heater. Page 11 of 25 REVISION: 05 DATE: 14 August 2019


12 Ripon Grove, Elsternwick Section J Report – Performance Solution

(c) A time switch must be provided in accordance with Specification J6 to control the operation of a circulation pump for a swimming pool. (d) For the purpose of J7.3, a swimming pool does not include a spa pool.

3.9 SECTION J8: FACILITIES FOR ENERGY MONITORING (a) A building or sole-occupancy unit with a floor area of more than 500m2 must have the facility to record the consumption of gas and electricity. (b) A building with a floor area of more than 2,500m2 must have the facility to record individually the energy consumption of – (iii) air-conditioning plant including, where appropriate, heating plant, cooling plant and air handling fans; and (iv) artificial lighting; and (v) appliance power; and (vi) central hot water supply; and (vii) internal transport devices including lifts, escalators and travelators where there is more than one serving the building; and (viii) other ancillary plant. (c) The provisions of (b) do not apply to a Class 2 building with a floor area of more than 2,500m 2 where the total area of the common areas is less than 500m2

4 PERFORMANCE MODELLING As there are no Occupancy and Operation Profiles provided within the NCC for Class 4 buildings, the profiles of a Class 3 building were applied for this assessment. Therefore, the development is assumed to have a similar plant operating profile, internal gain, equipment schedule, lighting schedule, and infiltration value as a Class 3 development and will utilise NCC Specification JV Table 2a where applicable. Illumination density is assumed to be similar to a standard Class 1 residential building. Item
