1. EXECUTIVE SUMMARY 1.1 INTRODUCTION The following report provides information regarding the compliance status of the proposed building at 1200 Great Ocean Road, Bellbrae with the BCA 2015 Section J requirements J1 to J3. Below is a summary of necessary actions to achieve compliance without modification to the current architectural design. Minimum added roof insulation of R4.0 Minimum added external wall insulation of R2.5 Minimum added internal wall insulation of R2.5 between conditioned and unconditioned spaces (including to amenities and loading dock). External glazing to have a maximum U-Value of 4.5 and maximum SHGC of 0.55. These values must include the frame. To achieve compliance, the above items and all sub-clauses as detailed in this report must be incorporated into the building design and noted on the specifications. 1.2 SOURCES OF INFORMATION The following sources of information were used to generate the rating: 1.3 LIMITATIONS Drawings: - Architectural drawings provided by FMSA. Computer building simulation provides an estimate of building performance. This estimate is based on a necessarily simplified and idealised version of the building that does not and cannot fully represent all of the intricacies of the building once built. As a result, simulation results only represent an interpretation of the potential performance of the building. No guarantee or warranty of building performance in practice can be based on simulation results alone. / ADP Consulting Pty Ltd / / Page: 3 of 24 / / Revision: 01 /

3.7 BUILDING SEALING External Windows and Doors Doors have been modelled with a compressible weather seal. All entrance doors have been modelled to be self closing. Exhaust Fans Exhaust fans have been modelled with self-closing dampers. Roof, Walls and Floors The building has been modelled with internal fixing and lining procedures such as skirting and cornices. / ADP Consulting Pty Ltd / / Page: 8 of 24 / / Revision: 01 /

3.8 CLIMATE DATA ApacheSim is driven by hourly weather data on temperature, solar radiation, cloud cover, wind speed, and wind direction. The data is in the form of a Test Reference Year (TRY), which contains mean values for each climatic parameter for the whole year. The location of Aireys Inlet was selected in the modelling program as this was considered to be most representative of the actual location. A Melbourne weather file was used for the simulation. The following is the temperature graph of the weather file used. FIGURE 1 - WEATHER FILE 3.9 EXTERNAL SHADE Shading has been included in the model as per the architectural drawings. / ADP Consulting Pty Ltd / / Page: 9 of 24 / / Revision: 01 /

3.10 BUILDING FORM The building form has been modelled as per the architectural drawings, representing zones, floors, facades, roofs, windows and shading devices, all with their respective design properties. Surrounding building and obstructions were included to give more accurate results based on the shading and wind factors. The model is shown in Figure 2.

4. PERFORMANCE REQUIREMENT: JP1 The following performance requirement specifies the intent of the energy efficiency provisions that apply to a Class 6 building under the BCA 2015 Section J energy efficiency provisions. A building, including its services, must have, to the degree necessary, features that facilitate the efficient use of energy appropriate to the function and use of the building and services; the internal environment; the geographic location of the building; the effects of nearby permanent features such as topography, structures and buildings; solar radiation being utilised for heating; controlled to minimise energy for cooling; the sealing of the building envelope against air leakage; the utilisation of air movement to assist heating and cooling; the energy source of the services. 5. VERIFICATION USING A STATED VALUE: JV3 The verification method (JV3) essentially provides flexibility where the prescriptive deemed-tosatisfy (DTS) provisions are sometimes too rigid or do not work for certain building designs. The verification methods can allow for innovation and better use of a buildings fabric and services in order to make the building more energy efficient. 1 (a) For a Class 3, 5, 6, 7, 8 and 9 building, compliance with JP1 is verified when it is determined that the annual energy consumption of the proposed building with its services is not more than the annual energy consumption of a reference building when (i) the proposed building is modelled with the proposed services; and (ii) the proposed building is modelled with the same services as the reference building. As the building services comply with minimum BCA Section J DTS Requirements, the thermal model and this report specifically focus on achieving compliance of the building fabric. The model therefore compares the Reference Services & Proposed Fabric against the Reference Services & Reference Fabric. As the services exceed the minimum DTS requirements, it is not necessary in this report to determine the Proposed services & Proposed Fabric. (b) The annual energy consumption of the proposed building in (a) may be reduced by the amount of energy obtained from (i) a source that is renewable on-site such as solar, geothermal or wind; or (ii) another process as reclaimed energy. No renewable energy is currently proposed as part of these works. 1 Building Code of Australia 2015 Section JV3 / ADP Consulting Pty Ltd / / Page: 11 of 24 / / Revision: 01 /

(c) The annual energy consumption calculation method must comply with the ABCB Protocol for Building Energy Analysis Software. IES Virtual Environment currently complies with the ABCB Protocol for Building Energy Analysis Software. (d) The annual energy consumption in (a) must be calculated (i) for the reference building, using (A) the Deemed-to-Satisfy Provisions for Parts J1 to J7 but including only the minimum amount of mechanical ventilation required by Part F4; and (B) a solar absorptance of 0.6 for external walls and 0.7 for roofs; and (C) the maximum illumination power density without any increase for a control device illumination power density adjustment factor; and (D) air-conditioning with the conditioned space temperature within the range of 18 CDB to 26 CDB for 98% of the plant operation time; and (E) the profiles for occupancy, air-conditioning, lighting and internal heat gains from people, hot meals, appliance, equipment and hot water supply systems (aa) of the actual building provided the operating hours per year are not less than 2,500; or (bb) of Specification JV; and (F) infiltration values (aa) for a perimeter zone of depth equal to the floor-to-ceiling height, when pressurising plant is operating, 1.0 air change per hour; and (bb) for the whole building, when pressurising plant is not operating, 1.5 air change per hour. All clauses mentioned in section (d)(ii) have been met in the thermal model of the Great Ocean Road Ice Creamery. (ii) for both the proposed building and the reference building using the same (A) annual energy consumption calculation method; and (B) location, being either the location where the building is to be constructed if appropriate climatic data is available, or the nearest location with similar climatic conditions in the same climate zone, for which climatic data is available; and (C) adjacent structures and features; and / ADP Consulting Pty Ltd / / Page: 12 of 24 / / Revision: 01 /

(D) environmental conditions such as ground reflectivity, sky and ground form factors, temperature of external bounding surfaces, air velocities across external surfaces and the like; and (E) orientation; and (F) building form, including (aa) the roof geometry; and (bb) the floor plan; and (cc) the number of storeys; and (dd) the ground to lowest floor arrangements; and (ee) the size and location of glazing; and (G) external doors; and (H) testing standards including for insulation, glazing, water heater and package air-conditioning equipment; and (I) thermal resistance of air films including any adjustment factors, moisture content of materials and the like; and (J) dimensions of external, internal and separating walls; and (K) surface density of envelope walls over 220 kg/m2; and (L) quality of insulation installation; and (M) assumptions and means of calculating the temperature difference across air-conditioning zone boundaries; and (N) floor coverings and furniture and fittings density; and (O) internal shading devices, their colour and their criteria for operation; and (P) number, sizes and floors served by lifts and escalators; and (Q) range and type of services and energy sources other than energy generated on-site from sources that do not emit greenhouse gases such as solar and wind power; and (R) internal artificial lighting levels; and / ADP Consulting Pty Ltd / / Page: 13 of 24 / / Revision: 01 /

(S) internal heat gains including people, lighting, appliances, meals and other electric power loads; and (T) air-conditioning system configuration and zones; and (U) daily and annual profiles of the (aa) building occupancy; and (bb) operation of services; and (V) range of internal temperatures and plant operating times; and (W) supply hot water temperature and rate of use; and (X) infiltration values unless there are specific additional sealing provisions or pressure testing to be undertaken; and (Y) unit capacity and sequencing for water heaters, refrigeration chillers and heat rejection equipment such as cooling towers; and (Z) metabolic rate for people. All clauses mentioned in section (d)(ii) have been met in the thermal model of the Great Ocean Road Ice Creamery. (iii) for the proposed building using a solar absorptance for the roof and walls 0.05 higher than that proposed; and (e) Where the annual energy consumption of the hot water supply or the lifts and escalators are the same in the proposed building and the reference building, they may be omitted from the calculation of both the proposed building and the reference building. The hot water complies with the DTS method and therefore is not included in the thermal model. No lifts are included in this development. (f) A lift in a building with more than one classification may be proportioned according to the number of storeys of the part for which the annual energy consumption is being calculated. As no lifts are included in this development, this clause is not applicable. / ADP Consulting Pty Ltd / / Page: 14 of 24 / / Revision: 01 /

(g) The design must include (i) the ability to achieve all the criteria used in the annual energy consumption calculation method such as having an automatic operation controlling device capable of turning lighting, and air-conditioning plant on and off in accordance with the occupancy and operating profiles used; and (ii) compliance with (A) J1.2 for general thermal construction; and (B) J1.3(c) for compensation for a loss of ceiling insulation; and (C) J1.6(a)(ii), J1.6(c) and J1.6(d) for floor edge insulation; and (D) BS 7190 for testing a water heater. The design complies with all components specified in clause (g) / ADP Consulting Pty Ltd / / Page: 15 of 24 / / Revision: 01 /

6. METHODOLOGY To achieve compliance via JV3, the building has been modelled using the IES <Virtual Environment> computer modelling software version 2014.2.1.0. The Virtual Environment software uses dynamic modelling which complies with the BCA requirements for computer simulation software and is currently listed on the Practice note Building energy analysis for commercial buildings. This IES software has undergone testing to the ANSI/ASHRAE Standard 140-2004, Standard Method of Test (SMOT) for the Evaluation of Building Energy Analysis Computer Programs and was found to be acceptable under the tests for building envelope, fabric load tests and HVAC equipment performance tests. The component of the IES software used for the thermal simulation was ApacheSim. ApacheSim is a dynamic thermal simulation program based on first principles, mathematical modelling of heat transfer processes occurring in and around a building. Conduction, convection and radiation heat transfer processes for each element of the building fabric are individually modelled and integrated with models of room heat gains, air exchanges and plant 2. ApacheHVAC was used to simulate the performance of heating, air conditioning and ventilation systems. ApacheHVAC extends the capabilities of ApacheSim by providing a detailed representation of room heating and cooling units, air handling units, central plant components and controls 3. ApacheHVAC allows performance curves and sizes of real plant items to be entered into the simulation. MacroFlo was used for simulating infiltration and natural ventilation. MacroFlo uses a zonal airflow model to calculate bulk movement in and through the building, driven by wind and buoyancy induced pressures 4. Suncast was used to simulate the effects of the sun hourly throughout the year. This takes into account the heat gain entering the building and its associated effects on the HVAC. Full details of the assumptions and settings used in the modelling are provided in Appendices 1 and 2. 2 ApacheSim User Guide 3 ApacheHVAC Use Guide 4 MacroFlo User Guide / ADP Consulting Pty Ltd / / Page: 16 of 24 / / Revision: 01 /

7. RESULTS 7.1 DTS SERVICES & PROPOSED BUILDING FABRIC The proposed building has been modelled using the proposed construction drawings with proposed building fabric and DTS services as specified in section 3 of this report. Simulation results are shown in table 2. Only results relevant to comparing the Proposed and DTS fabric have been included. Other results that remain the same for both models have been omitted for clarity.

7.2 REFERENCE SERVICES & REFERENCE BUILDING FABRIC Simulation results for the building with DTS building fabric and DTS services are shown in Table 3. The following performance data was modified from the proposed design to align the model with minimum DTS requirements; TABLE 3 - DTS GLAZING CALCULATOR - GROUND / ADP Consulting Pty Ltd / / Page: 18 of 24 / / Revision: 01 /

Building fabric has been modelled using the minimum DTS requirements as follows; o R2.8 for the walls with a solar absorptance of 0.6; o o R3.2 for the ceilings, along with a solar absorptance of 0.7; and R1.8 for walls between conditioned and unconditioned spaces. As the mechanical and electrical systems currently meet all aspects of the DTS method, it is not necessary to modify these services in the reference building as this can only improve the energy use and therefore the current calculations allow for a conservative approach focused only on the building fabric. Only J1 to J3 are being analysed through the JV3 method. / ADP Consulting Pty Ltd / / Page: 19 of 24 / / Revision: 01 /

The total energy consumption for the Reference Building with the DTS building fabric and DTS services is 222.43 MWh/annum.
