1. EXECUTIVE SUMMARY

Sustainable Built Environments (SBE) reviewed the Town Planning drawings for the proposed multi-dwelling development at 97-99 Queens Parade, Clifton Hill and has undertaken a daylight assessment in accordance with the GBCA Green Star - Design & As Built v1.1 methodology.

Best Practice Standard targets for daylight as noted within the Built Environment Sustainabilitv Scorecard (BESS) are:

• Bedrooms: Achieve a daylight factor (DF) of 0.5 or more for at least 90% of the floor area;

• Living Areas: Achieve a daylight factor (DF) of 1.0 or more for at least 90% of the floor area;

For the purpose of this assessment each living area and each bedroom across the development has been assessed. The analysis results show that 74% of bedrooms and 100% of living areas achieve the required minimum daylight factor.

When entered into the BESS tool under the Indoor Environment Quality (IEQ) category, along with all the other credits, these analysis results contribute to a score of 63%, thus demonstrating compliance with Council's requirements.

A summary of the daylight analysis results is presented below.

2. INTRODUCTION

Sustainable Built Environments (SBE) has been commissioned to review the design of the proposed multi-dwelling development at 97-99 Queens Parade, Clifton Hill and to report on the daylight performance achieved with respect to Yarra City Council's Best Practice Standard targets.

2.1 The Project

The project involves the development of nine (9) new townhouses on single block of land. Each townhouse features open-plan kitchen/dining/living area, three (3) bedrooms, two (2) bathrooms, laundry, and a communal below-ground undercover garage.

The townhouses are integrated within a site containing a heritage-listed building (excluded from this assessment), providing a thoughtful development that complements the street character.

2.2 Assessment Scope and Methodology

The scope of this report is to complete a daylight and solar access assessment to determine the daylight and solar access performance of the proposed development. The design has been assessed against Council's Best Practice Standard with the calculation being completed in accordance with GBCA Green Star — Design & As Built v1.1 methodology.

A basic outline of the procedure undertaken is noted below:

• Determine the most appropriate weather data file and apply to the site.

A weather data file is defined as a set of real measured hourly values for dry temperature, global, diffuse direct normal solar radiation, wind velocity, and other climatic variables. The data is in true sequence within each month. The months nominated are selected from a multiple year data set of observations for a given location such that the resulting weather data is typical for the location.

• Create a 3D model of the proposed building and any adjacent obstruction in the simulation software.

• Conduct the simulation.

2.3 City of Yarra Planning Requirements

Yarra City Council has signed to the use of the Built Environment Sustainability Scorecard (BESS) has the principal tool to benchmark development within the municipality. BESS details the minimum requirements and Best Practice Standard for nine (9) sustainable building categories. One of these categories is Indoor Environment Quality (IEQ), with one of the items discussed in this section being internal daylight levels. In this category, BESS provides the following Best Practice Standard, which is what the proposed design has being assessed against.

• Bedrooms: Achieve a daylight factor (DF) of 0.5 or more for at least 90% of the floor area;

• Living Areas: Achieve a daylight factor (DF) of 1.0 or more for at least 90% of the floor area;

2.5 Modelling Software

Daylight and solar access modelling of the development has been undertaken using IES VE version 2015.2.2.0 which is recognised by the NCC as a compliant modelling software and has satisfied BESTTEST with the International Energy Agency (IEA).

ModelIT, SunCast and FlucsDL modules have been used to built the model and run the simulation.

The computer model has been created to account for all physical, climatic and geographic attributes of the proposed development to predict the daylight performance of the building over a period of 12 months.

2.6 Use of this Report

3. MODELLING PARAMETERS

The modelling inputs used for assessment are reported below.

Simulation Element Description

Software IES VE 2015 with SunCast and FlucsDL Toolkit

Sky Uniform Design Sky (UDS)1 Melbourne IWEC weather data

Horizontal external illuminance at 10,000 Lux Working Plane Daylight Factor levels taken at floor level

Floor reflectance 0.3

Wall reflectance 0.7

Ceiling reflectance 0.8

Roof reflectance 0.3

Ground reflectance 0.3

External glazing Visible Light 0.7 Transmittance (VLT) Overshadowing Neighbouring buildings to the east and west of the development that provide

overshadowing have been included within the model. Local shading All balconies, canopies and reveals have been modelled as per the architectural

drawings. Glazed balustrades have been omitted from the model.

The perforated screens on Level 1 have been modelled as a solid screen that allows 25% of visible light transmission through it.

3.1 Determining Assessable Areas

Each open plan living space and each bedroom has been assessed for daylight performance. Corridors and circulation areas, amenities, and storage areas have been excluded from the assessment as these are typically transient or non-habitable spaces where high levels of daylight are not required.

Where transient areas or non-habitable rooms are open (not enclosed by doors) to adjacent living areas and/or bedrooms (e.g. stairs), these have been physically separated with an open partition in the modelling software.

A Uniform Design Sky represents a sky with a constant value of luminance. Thus, no matter where in the sky you look, the model has the same value. Design Sky values are derived from a statistical analysis of outdoor illuminance levels. They represent a horizontal illuminance level that is exceeded 85% of the time between the hours of 9am and 5pm throughout the year. Thus they also represent a worst-case scenario that a building can be designed to and ensure it will meet the desired light levels at least 85% of the time.

1. EXECUTIVE SUMMARY

Sustainable Built Environments (SBE) has been commissioned to provide an Ecologically Sustainable Design (ESD) report for the proposed multi dwelling development at 97-99 Queens Parade, Clifton Hill.

The aim of the ESD report is to identify and convey the key sustainability opportunities embraced in the design, and provide the Responsible Planning Authority with a clear indication of how the development achieves the City of Yarra ESD policy aims and objectives.

SBE has used the Built Environment Sustainability Scorecard (BESS) to benchmark the design's potential ESD performance under each key ESD criteria including: management, water and energy efficiency, stormwater, indoor environment quality (IEQ), sustainable transport, waste, urban ecology, materials and innovation.

The proposed development currently targets 52 points out of 100 in BESS (see extract below), which equates to Australian Best Practice. Further, BESS has calculated that the design responses proposed for this development will achieve a 36% reduction in potable water consumption, a 58% reduction in electricity consumption and 39% reduction in gas consumption compared to a reference building. We understand this will satisfy Council's desired performance of development within its boundaries.

The configuration of the proposed development as a series of townhouse rather than a more conventional apartment building provides a number of additional benefits including:

• Greater potential for interaction between residents due to the layout of the private open spaces facing the internal walkway.

• Improved security as a result of the line of sight from the townhouses to the internal walkway.

• Improved amenity by offering each townhouses at least two exposed facades.

• Effective natural cross-ventilation and buoyancy ventilation due to opposing exposed facades and the stair-case void.

• Improved access to a range of views and vistas over the three levels.

2. INTRODUCTION

Sustainable Built Environments (SBE) has been commissioned to provide an Ecologically Sustainable Design (ESD) report for the proposed multi dwelling development at 97-99 Queens Parade, Clifton Hill.

This Ecologically Sustainable Design (ESD) report developed for Town Planning provides an overview of the key sustainable design initiatives and predicted environmental performance of the proposed development. The report addresses the City of Yarra commitment to promoting good ESD outcomes in the built environment and demonstrates how this is being achieved within the project.

2.1 The Project

The project involves the development of nine (9) new townhouses on single block of land. Each townhouse features open-plan kitchen/dining/living area, three (3) bedrooms, two (2) bathrooms, laundry, and a communal below-ground undercover garage.

The townhouses are integrated within a site containing a heritage-listed building (excluded from this assessment), providing a thoughtful development that complements the street character. The configuration of the proposed development as a series of townhouse rather than a more conventional apartment building provides a number of additional benefits.

Greater potential for interaction between residents is provided due to the layout of the private open spaces facing the internal walkway. This layout has in fact the potential to create a village-style living feeling within the development which facilitates positive engagement between residents. Further, the accessible line of sight from the townhouses to the internal walkway improves security.

Effective natural ventilation and amenity is also improved within this development. Each townhouse has at least two exposed facades, which allow for cross-ventilation as well as buoyancy ventilation through the stair-case void. A range of views and vistas is also provided over the three levels of each townhouse.

2.3 City of Yarra Planning Requirements

Clause 22.17 of the Yarra Planning Scheme - Environmentally Sustainable Development, sets out a number of policy objectives under key sustainability categories. The overarching objective of this policy is that development should achieve best practice in environmentally sustainable development from the design stage through to construction and operation.

sbe 170113_97-99 queens pde sustainability design assessment_v1.doc 6

U

a For residential developments of between 2 and 9 dwellings, a Sustainability Design Assessment (SDA) must

111 accompany the Town Planning application.

An SDA is a detailed sustainability assessment of a proposed design which demonstrates a comprehensive 11 investigation and review of the ways in which a development addresses key environmental criteria and how these ■ achieve Council policy objectives.

In an RFI dated 28 December 2016, Council requested the development of a Sustainable Design Assessment (this

111 report) in accordance with clause 22.16 (Stormwater Management) and 22.17(Ecologically Sustainable Development).

3. DESIGN

• • •

The ultimate environmental design aim for our built environment is to create buildings that are comfortable, use no energy, no water, that neither produce waste in operation or create waste in their construction, and are made from materials that derive totally from sustainable sources. Although this may not be achievable by all buildings, it nonetheless provides an inspirational goal and an opportunity to consider best practice design solution.

Environmental Strategy

A sound strategy for reducing the environmental impact of a project is to tackle the design in three ways and in this order of priority:

1. Reduce the demands on active systems in the building by enhancing the passive performance of the building. This includes optimising orientation, shading, insulation, daylighting, ventilation and longevity.

2. Select and specify the most efficient active systems available to satisfy the resultant demands of the building.

3. Offset the resultant energy demands of the building with local or off site mechanisms, for example Photo Voltaic panels or solar hot water.

The above numbered items are also generally in decreasing order of cost effectiveness over the life of the building.

4. MANAGEMENT

It is important to encourage an environmental focus in the management of design, construction and operational phases of the development. The Management category aims to highlight the importance of a holistic and thoroughly integrated approach to constructing and operating a building with good environmental performance.

Management initiatives may include: engaging a professional with a thorough understanding of green building principles; conducting early energy and thermal assessment to help optimise the design, managing construction activities to minimise pollution and maximise soil and air quality protection; enhanced commissioning and tuning of building systems; as well as information management initiatives such as user training and data monitoring.

Building User Information

To encourage and recognise initiatives that will help building users to use the building efficiently

This assessment has been carried out by an appropriately qualified ESD Professional at SBE. SBE has been involved in the design since early stages and has provided sustainability advice to the project team. A preliminary NatHERS assessment has been conducted for the development. Results from the assessment indicate that all dwellings shall achieve a minimum rating of 6 stars.

For more information on the preliminary NatHERS assessment and results refer to Appendix A. All major common area services (e.g. common lighting, car park exhaust fan, etc.) shall be separately sub-metered.

A building user guide shall be developed by the project team. Although it is responsibility of the design team to decide on the appropriate content of the building user guide, the following typical information may be provided:

• Description of initiatives designed to enhance energy efficiency and minimise greenhouse gas emissions, and measures that must be taken by users during day-to-day operation to maximise their effectiveness;

• Description of initiatives intended to enhance and minimise water use and the measures that must be taken by users during day-to-day operation to maximise their effectiveness;

• Description of basic function and operation of any nominated building systems that building users may come in direct contact with including any occupant activated controls;

• List of relevant contacts for maintenance information, operational issues, complaints or other feedback (e.g. relevant facilities management contact details and/or online request/feedback form);

• Description of alternative transport initiatives promoted within premises, and the location of a transport plan (if available);

• Local public transport information, maps, and timetables;

• Description of the operational waste requirements for the building users, including what waste streams can or cannot be collected for recycling at the premises;

• Information on how to maximise the efficiency potential offered by base building services and nominated building systems; and

• Information on how to best maximise day lighting, sights and views.

To encourage the involvement of suitably qualified ESD professionals in the project team from the early design stage.

To encourage and recognise developments that have used modelling to inform passive design at the early design stage

To provide building users with information that allows monitoring of energy and water consumption

5. WATER

In Australia, water has long been considered a precious and high-demand resource. Fresh water supplies are increasingly affected by a range of factors including catchment locations, contaminated sources, drought and rising demand. Australia remains the driest inhabited continent in the world with the third largest per capita water consumption rates, and demand for water is close to outstripping supply in many major cities'.

In addition to reducing the demand for water, efficient use of water in buildings can reduce building owners' operational costs. This category aims to minimise the impacts on the environment from extensive water use in the built environment. Demand for potable water can be reduced through recycling from rainwater, greywater and blackwater. Currently, less than ten percent of Australia's sewage is being recycled.

BESS has calculated that the design responses proposed for this development will achieve a 36% reduction in potable water consumption compared to a reference building.

Aim Design Response! Project Compliance

Rainwater Tank

One 15,000 litre rainwater tank connected to all sanitary flushing systems shall be installed. The rainwater tank shall collect rainwater from the townhouses roof (approx. 440m2)

Refer to Appendix B for a copy of the STORM report. All sanitary fixtures shall have the WELS rating stated below:

• Taps — 5 Stars • Toilets — 4 Stars • Showers — 3 Stars (>6.0 but <=7.5) • Dishwashers (if installed as part of the base built)-

5 Stars

Sanitary Fixture Efficiency

To encourage building design that minimises potable water consumption in operations.

Building Systems Water Use Reduction

If installed, test water from sprinklers shall be collected and re-use within the fire protection system.
