3 ESD ASSESSMENT

Indoor Environment Quality

An effective indoor environment quality response ensures that occupants within a particular space remain healthy and comfortable. Buildings are designed for people; and reduction in energy use or the inclusion of any other sustainability attribute should never be made at the expense of the occupant’s health and wellbeing. Indoor environment quality includes design considerations such as daylight, thermal comfort and natural ventilation.

Objectives

To achieve a healthy indoor environment quality for the wellbeing of building occupants To provide a naturally comfortable indoor environment will lower the need for building services, such as artificial

lighting, mechanical ventilation and cooling and heating devices

Actions The following table outlines the actions that the development has taken to achieve the above objectives for indoor environment quality.

COUNCIL BEST PRACTICE STANDARD CRITERIA DEVELOPMENT PROVISION

Sufficient Daylight

The average daylight factor for 90% of the habitable floor area should achieve 1.0% for living areas and 0.5% for bedrooms.

Townhouses:

All habitable areas in the townhouses are less than 8m deep or have windows on opposite sides.

The townhouses will have a minimum floor-to-ceiling height of 2.70m.

Apartments:

24% (44 out of 187) of the apartments are less than 8m deep.

The apartments will generally have a floor-to-ceiling height of 2.70m.

Townhouses and Apartments:

Bedroom windows located on the perimeter will be provided with glazing <60% visible light transmittance.

Recessed living area and bedroom windows will be provided with glazing >60% visible light transmittance (i.e. clear glazing).

All living areas have an external facing window.

84% of living areas and all bedrooms of the apartment and townhouses comply with the requirements of the building separation tables.




Direct Sunlight

Living rooms and private open spaces for at least 70% of apartments in a development should receive a minimum of three hours direct sunlight between 9am and 3pm in mid-winter.

All townhouses and 28% of apartments meet this benchmark given the recessed living area windows to the east and west.

Window Sizes

Size windows at 20% of a rooms floor area to balance access to daylight, heat loss in winter and solar heat gains throughout the year.

Windows are sized at minimum of 22% of their associated room floor areas. As these apartments are achieving a preliminary 6.5 star average for energy, they are considered well balanced for daylight, heat loss and solar gains.

The envelope of the proposed retail and office areas is to be of a high standard to achieve compliance with current NCC 2016 Section J.

Southerly Aspect Apartments

Limit the number of single-aspect apartments with a southerly aspect (SW-SE) to a maximum of 10% of the total apartments proposed.

None of the development’s apartments or townhouses are single-aspect south facing dwellings.

Internal Bedrooms

Limit the number of apartments with internal bedrooms to a maximum of 10% of the total apartments proposed.

NIL internal bedrooms.

Cross-Ventilation

At least 60% of a development’s apartments should be naturally cross ventilated.

All of the development’s apartments are naturally cross-ventilated or passively ventilated by makeup air from the naturally ventilated corridor.

The corridors will be fitted with fully automated windows, including external temperature, wind and rain sensors.

Courtyards

Courtyards in multi storey buildings should be a maximum of four storeys in height to ensure adequate daylight access to the open space and apartments. Internal courtyard dimensions should not lead to the requirement of screening in regard to overlooking.

There are no courtyards in this development.




Acoustics

Consider acoustic impacts when designing for a natural ventilation strategy.

Glazing facing Warrigal Road will be appropriately sized to moderate noise between outside environment and apartments. Acoustic engineer to nominate appropriate dBLaeq levels for the development.

External Shading

Install appropriate external shading devices which respond to different façade orientations.

The development is provided with a comprehensive shading strategy including:

Office and Retail Areas:

- West facing windows of the retail tenancies at lower ground will be shaded by a 1-2.7m deep overhang.

- West facing windows of the office/childcare tenancy at upper ground will be self-shaded by way of serrated façade elements in combination with textured glazing.

- West facing windows of the office/childcare tenancy at level 1 will be self-shaded by strategically placed wing wall to the north and the roof overhang to the west which extends up to 2.3m from the facade.

Townhouses:

- West facing windows of the townhouses will be shaded by a combination of wing walls and overhangs of the floor above.

- East facing windows of the townhouses will be shaded by overhangs of the floor above and bronze mesh screening.

Apartments:

- All recessed apartment living area windows will be shaded by a combination of the overhanging balconies of the floor above and wing walls.

- All apartment bedroom and living area windows located on the perimeter will be shaded by bronze mesh screening.

Further indoor environment quality actions provided by the proposed development are outlined below:

INDOOR ENVIRONMENT QUALITY ACTIONS

External Views All living, retail (excl. Supermarket) and office areas are provided with a full height glazed façade through which they can absorb views of the external environment.

Hazardous Materials and VOCs

Low VOC paints, adhesives, sealants, carpets and wall and ceiling coverings will be specified in accordance with Green Star Design & As-Built Rating tool credit criteria for ‘13.1 Paints, Adhesives, sealants and Carpets’.



INDOOR ENVIRONMENT QUALITY ACTIONS

Formaldehyde Minimisation

Engineered wood products provided to the development will be low in or contain no formaldehyde. Formaldehyde levels shall be deemed acceptable if they are in accordance with Green Star Design & As-Built Rating tool credit criteria for ‘13.2 Engineered Wood Products’. Formaldehyde has been reported to be a slight irritant to eyes, nose and throat, lead to sensitive skin and respiratory system, cause an increased risk of cancer and lead to reproductive hazards.

Electric Lighting Levels

Lighting that is too dim or too bright can cause discomfort and strain for occupants. Providing adequate lighting at key areas such as the kitchen sink, stove and bathroom vanity basins increases the comfort to users without having to illuminate a large open space. A minimum of 300 Lux will be achieved in each of these areas. This is in line with the Green Star Design & As-Built Rating tool credit criteria for ‘11.1 General Illuminance and Glare Reduction.’

Private External Space

The apartments and townhouses have all been designed with balconies and private open space for access to the outdoors year-round.



Energy Efficiency

The buildings sector and people’s activities in buildings are responsible for approximately 31% of global final energy demand, approximately one-third of energy-related CO2 emissions, approximately two-thirds of halocarbon, and approximately 25–33% of black carbon emissions (Ürge-Vorsatz et al.). Improving the energy efficiency of buildings is one of the most cost-effective ways to reduce greenhouse gas emissions and respond to the growing threat of global climate change. By implementing appropriate measures at the design and construction phases of development projects, the potential exists to significantly improve the operational performance of Australia’s future building stock. Multi-unit residential developments such as that proposed at 695 Warrigal Road, Chadstone possess a range of inherent environmental benefits. These include operational efficiencies due to reduced footprint relative to density, enhanced social and community sustainability. Objectives

To ensure the efficient use of energy To reduce total operating greenhouse emissions To reduce energy peak demand To reduce associated energy costs

Actions


Shading

Install appropriate external shading devices responding to different façade orientations.

Please see ‘external shading’ under indoor environment quality above.

Energy Efficiency

Demonstrate energy efficiencies beyond minimum BCA compliance benchmarks (e.g. 10% or + 1 star).

The National Construction Code (NCC) Class 2 – Sole Occupancy Unit(s) residential building component is to be designed in accordance with NCC Section J (2015) NatHERS requirements. The residential units must achieve an average 6.5 Star rating, with no unit achieving below 5 Stars.

The apartments and townhouses are currently achieving a 6.5 Star average. This represents > 10% improvement on minimum NCC compliance benchmarks. The below sample ratings demonstrate the developments ability to achieve this average:

The proposed retail and office areas are targeting a 20% energy efficiency improvement compared to the current BCA compliance benchmark. This will be verified by way of BCA Section J - JV3 Reporting prior to the commencements of construction works.

Natural Lighting

Ensure habitable rooms do not rely on artificial lighting throughout the day.

All living/kitchen areas, bedrooms, retail (excl. supermarket) areas and office areas are provided with full height glazing to enhance natural light.

Energy efficient lighting

Install energy efficient artificial lighting including sensible lighting conditions.

The lighting strategy seeks to encourage natural daylighting (for ambient light) where possible. Light coloured finishes are to be applied to encourage light diffusion within spaces served. Access to daylight will reduce reliance on artificial lighting.

Lighting for the development is to be LED typically. High efficiency fluorescent T5 type lighting will be provided to the carpark and services areas only.

Lighting power density shall be as follows:

Dwellings: No greater than average 4W/m2 Veranda/balcony/terrace: No greater than average 4W/m2 Back of house and indoor car parks: No greater than average 5W/m2

All common areas are to be controlled with daylight, motion sensors or timers (whichever is deemed appropriate).

External lighting is to be controlled by motion detectors.

Carpark lighting is to be controlled with motion sensors.




In addition to the above, all external electrical lighting luminaires are to have an upward light output ratio of less than 5% and the external lighting design to comply with AS 4282 – ‘Control of the obtrusive effects of outdoor lighting’. This is in line with the Green Star Design & As-Built Rating tool credit criteria for ‘Light Pollution’.

Clothes Drying

Provide external clothes drying facilities.

Drying racks / lines will be provided to apartments and townhouses internally with the expectation that occupants will place these racks on balconies or POS during use.

Renewable Energy

Consider renewable energy production for a proportion of water heating, heating and electricity demands.

A 10kW Solar PV System is to be located on the roof of building A and B. The PV panels are to be placed facing due north with an inclination of 30 degrees.

Heating and Cooling

Specify energy efficient (high star rating) heating and cooling systems.

When outdoor conditions are not conducive to natural ventilation, air conditioning will be used. Inverter split system units are to be installed and sized to maintain conditions of the main living space of each apartment and townhouse. The efficiency of the air conditioning system is to be within 1 star rating of best available under MEPS Post-October 2011 measurement standard.

Hot Water

Install energy efficient (high star rating) HWS

Apartments, Office and Retail Areas: A development is to utilise a centralised gas hot water system, with either:

6 Star energy rating for instantaneous units; or Minimum 80% energy efficiency for a single water heater

Townhouses: Electric instantaneous units will be applied to the townhouses. The relative CO2 emission differential between gas and electric will be offset by way of solar PV. Refer Renewable Energy above.

Further energy efficiency actions provided by the proposed development are outlined below:

ENERGY EFFICIENCY ACTIONS

Energy Sub-Metering

Electricity and hot water metering is to be provided to each residential unit, townhouse and individual retail and office tenancies. This measure is aimed at encouraging user awareness and accountability and it is likely to lead to more responsible energy use.

Lighting and general power to common areas is to be separately metered to quantify energy used for common areas spaces.



ENERGY EFFICIENCY ACTIONS

Air Leakage Minimised

Emphasis is to be placed on the builder’s workmanship to achieve air tight building construction throughout. Seals may be a foam or rubber compressible strip. Sealing of gaps and cracks, correct installation of insulation, caulking, etc. are imperative in achieving an energy efficient thermal envelope. Doors and windows will be suitably weather sealed and self-closing where appropriate.

The intent is to provide well sealed internal environment with controlled passive ventilation functionality.

All mechanical extraction points within SOU’s, retail and office areas will be self-closing when not in use.

Carpark Ventilation

Basement carpark ventilation fans are to be supplied with VSDs coupled with CO sensors. Upper ground and level 1 carpark will be provided with perforated wall structures (where deemed appropriate) in order to facilitate natural ventilation.

Efficient Cooking Appliances.

High efficiency ovens and low emission gas or induction cooktops shall be used in each apartment or townhouse.



Water Efficiency and Stormwater Management

Although no longer in drought, Australia experienced its warmest and third warmest years on record throughout 2013 and 2014 respectively. An emphasis therefore, on water conservation and Water Sensitive Urban Design (WSUD) within new developments is essential. The development will incorporate the measures outlined below to reduce potable water consumption and reduce urbanisation impacts on stormwater systems. Objectives

To ensure the efficient use of water To reduce total operating potable water use To encourage the collection and reuse of stormwater To encourage the appropriate use of alternative water sources (e.g. grey water) To minimize associated water costs To reduce the impact of stormwater run-off To improve the water quality of stormwater run-off To achieve best practice stormwater quality outcomes To incorporate water sensitive urban design principles

Actions


WELS Rated Fixtures

The installation of WELS rated fittings within one star of best available.

Large reductions in water use can be obtained by using water efficient fittings. Water Efficient Labelling Scheme (WELS) rated fittings with the following star ratings are to be nominated:

WELS 4 Star rating, Dual Flush Toilet: (4.5/3L – average 3.5L/flush)

WELS 5 Star tap ware (<5.0L / minute) including aeration devices WELS 3 Star showerhead (>7.5L but ≤9.0L / minute) including

aeration devices WELS rated Dishwasher within 1 star of best available if provided

Rainwater tank

The installation of a rainwater tank that is sized to capture the vast majority of otherwise discharged rainwater and plumbed to a consistent year round water use such as toilet flushing.

A 20,000 litre rainwater tank will harvest rainwater from the upper roofs - apartment building A and B. This tank will be connected to all retail / office / childcare WC’s. It is estimated that this will save more than 427kL of potable water every year and meet 84% of the demand in these areas. Refer Figure 2 below for monthly rainwater demand and supply.




Metering

The installation of separate water meters in individual dwellings within the same development.

The apartments, townhouses and retail and office tenancies are to have individual cold and hot water meters. This measure is aimed at encouraging user awareness and accountability and it is likely to lead to more responsible water use.

STORM

Exceed Victoria’s best practice standards by achieving a MUSIC / STORM rating of at least 100% or equivalent modelling results.

The Melbourne Water - Stormwater Treatment Objective Relative Measure (STORM) tool has been applied to determine performance relative to Best Practice Environmental Management Guidelines (Victoria Stormwater Committee, 1999). As per clause 56.07 – Integrated Water Management of City of Monash Planning Scheme, new developments are required to integrate a waste water system that is adequate for the maintenance of public health and the management of effluent in an environmentally friendly manner. A Melbourne STORM rating of 107% is achieved via the following:

- Rainwater is to be collected from upper roofs (apartment building A and B) and directed into the 20kL rainwater tank. All retail / office / childcare WC’s are to be connected to the rainwater tank.

- Rainwater is to be collected from lower roof and townhouses roofs and directed into 300mm raingarden(s) with a total surface area of 20m2.

- Water collected from the upper ground paved area will be directed into a gross pollutant trap.

Results and mark-up can be found in Appendix B.

Building Materials

Materials selection has in recent years undergone a transformation in evaluation criteria. Designers are now challenged to address concepts such as embodied energy, life cycle impact, and indoor environment quality. The building industry has taken up the challenge with a plethora of eco-products available locally. Preference should be given to materials that can be easily recycled. Toxic and hazardous materials are to be avoided wherever possible. Objectives

Fate of material Recycling/Reuse Embodied energy Biodiversity Human health Environmental toxicity Environmental responsibility

Actions


Embodied Energy

Has a commitment to substitute some cement content of concrete with fly ash or slag been outlined? Limited or no use of aluminium, zinc and other high embodied energy metals and materials in general, especially in a design with intended high churn (e.g. retail)

The Green Star Design & As-Built Rating tool applies 30% measured in mass reduction against all concrete used. Portland cement will only be replaced in precast concrete elements. This initiative will be subject to approval from the project Structural Engineer. The design will seek to limit the use of superfluous high embodied energy metal finishes.

Habitat Destruction

Has a commitment to source timber from sustainably managed source, with proof of audit trail being provided?

Where timber is to be used, such timbers are to accord with the GBCA’s ‘Essential’ criteria for forest certification. This may include FSC and / or PEFC Certification which are both internationally recognised schemes ensuring that timber is sourced from sustainable sources. This is in line with the credit criteria for ‘Certified Timber’ under the Green Star Design & As-Built tool.




Recyclability / Reusability

Can the materials selected be recycled or reused? In Australia?

The development will seek to incorporate recyclable materials where appropriate. Fibreboard, cladding, steel, aluminium and concrete can be readily recycled in Australia.

Toxicity

Have efforts been made to avoid materials which are toxic in manufacture and use?

Material selections will generally be cross referenced against GECA and / or Ecospecifier to ensure materials are responsibly sourced and manufactured.

Transport

A commitment should be made to give preference to locally made materials first, then Australian made, then internationally made.

A commitment will be made to source some materials locally.

Suitability

Are the materials selected suitable for the intended application?

The materials selected are in keeping with the urban context of the area.

Maintenance/ Durability

Are the materials selected low in maintenance requirements and high in durability, relative to the chosen application and life expectancy of the development? Are low toxicity/pollution/energy use cleaning agents required for ongoing maintenance?

Material selections have typically been considered for durability over the lifespan of the development. No specific cleaning agents are required for the ongoing upkeep of the development.

Further building materials actions provided by the proposed development are outlined below:

BUILDING MATERIALS ACTIONS

Flooring and Joinery

All flooring and joinery provided to the development will have a reduced environmental impact (i.e. GECA/Ecospecifier certified or approved equivalent).



Transport

Transport emissions accounted for 14 per cent of Australia’s total domestic emissions in 2009 at 83 Mt CO2-e (BITRE, 2009). Sustainable transport aims to discourage private car usage and encourage alternative means of transportation. These include options such as public transport, cycling and walking. Objectives

To minimise car dependency. To ensure that the built environment is designed to promote the use of public transport, walking and cycling.

Actions


Car Share

For large developments, facilitate access to a car share program.

There are no car share schemes in close proximity of the proposed development.

Bicycle facilities

For residential developments, provide at least one secure bicycle parking space per dwelling.

In total 63 secure bicycle spaces for residents and employees will be provided to the development.

Additionally, 12 bicycle spaces for visitors and customers to the retail tenancies will be provided outside.

This number of bicycle parking spaces complies with the requirements for residents and visitors of City of Monash Planning Scheme - Clause 52.34-3 Bicycle spaces.

Fuel efficient vehicles

Provide parking facilities for fuel efficient vehicles.

5% motorbike and moped parking spaces will be included in the basement carpark. No car parking spaces are specifically intended for fuel efficient vehicles. Purchasers will be made aware of the benefits of fuel efficient and alternative fuel vehicles in the Building User Guide.

Waste Management

As Victoria’s population continues to grow, so too does the demand and subsequent strain on refuse disposal. State and Local Government has sought to address waste through a raft of strategies and practises. In particular, the cost of tip disposal has increased substantially and will continue to do so. This mechanism seeks to provide a cost effective alternative through reusing, reducing and recycling practises. Objectives

To ensure waste avoidance, reuse and recycling during the design, construction and operation stages of development.

To ensure long term reusability of building materials. To meet Councils’ requirement that all multi-unit developments must provide a Waste Management Plan in

accordance with the Guide to Best Practice for Waste Management in Multi-unit Developments 2010, published by Sustainability Victoria.

Actions


Recycling Target

Adopt a recycling target of at least 70% for all demolition and construction waste (by mass.)

The contractor will implement a waste management plan to ensure that at least 80% of demolition and construction waste (by mass) is recycled. The waste management plan will be developed in accordance with the MBAV Guidelines. Material sorting and appropriate demolition waste disposal is to be applied to the following streams:

Concrete, bricks, asphalt, timber, soil Steel, other metals Paper, glass, plastics, cardboard packaging Carpet, ceiling tiles, plumbing fixtures & equipment

Mechanical equipment, lighting fixtures & electrical components.

Operational Waste Management

Adequate facilities must be provided to ensure waste separation and possible on-site reuse is facilitated during the building’s operation.

Separate central garbage, recycling, and hard waste storage for the apartments, townhouses, retail and office areas is located in the upper ground carpark.

Composting bin facilities will be provided at level 2, located adjacent to the vegetable gardens.

Further waste management actions provided by the proposed development are outlined below:

WASTE MANAGEMENT ACTIONS

Construction Environmental Management Plan

A site specific Environmental Management Plan in accordance with Section 3 of the NSW Environmental Management System guidelines 2007 will be implemented for the development in line with the Green Star Design & As-Built tool credit criteria for ‘Environmental Management Plan’.



Urban Ecology

Over the past few hundred years, urban development has caused displacement and degradation of much of Australia’s natural flora and fauna and has reduced biodiversity in many areas. Site selection is one of the easiest ways to gain positive environmental outcomes within the building industry. Objectives

To protect and enhance biodiversity. To provide sustainable landscaping. To protect and manage all remnant indigenous plant communities. To encourage the planting of indigenous vegetation.

Actions


Ecological value

Enhance the ecological value of your site through the protection of existing vegetation.

The proposed site is currently the location of a large commercial building. Redeveloping the site will not only reduce the burden on previously undeveloped sites and greenfield urban sprawl, but also provides regeneration to the location and help to create a more socially cohesive and environmentally friendly residential community.

Vegetation

Provide additional vegetation that serves the amenity and environmental performance of the development.

Balconies or private open space have been provided to all apartment and townhouses allowing residents to cultivate their own gardens.

The majority of landscaped areas located at upper ground and level 2 will be provided with water efficient native vegetation.

Level 2 will be provided with 168m2 of vegetable garden allotments. Residents will have the access to allotments on a time share basis.

Further urban ecology actions provided by the proposed development are outlined below:

URBAN ECOLOGY ACTIONS

Urban Density

Low-density, dispersed cities are unsustainable as they are generally automobile dependent. The proposed medium density development, located in a previously developed Melbourne suburb is set to curb urban sprawl by providing residents with close proximity to Melbourne CBD and surrounds via the expansive surrounding public transport infrastructure.

Communal Space and Social Cohesion

The proposed development will be provided with significant communal area at upper ground and level 2. This initiative will stimulate social cohesion and interaction amongst occupants and give them the opportunity to engage with nature within close proximity of their home.



Innovation

Innovation refers to replenishing, varying or constructing more effective processes, products or ways of doing things. This could mean the implementation of new ideas, the creation of new products or the improvement of an existing service. Objectives

To encourage innovative technology, design and processes in all development, which positively influence the sustainability of buildings.

Actions


New technology

Introduction of new building technologies.

As building technologies continue to evolve, the development will commit to implementing the most current ESD relevant technologies at the time of construction. This will include HVAC systems, ventilation and lighting control systems, building materials, renewable energy technologies, lift systems etc.

Enhancements

Significant enhancements to a building’s environmental performance.

This has been addressed throughout this Sustainable Management Plan. Refer specific sections for relevant details.

Passive design

Responding to local climate conditions through passive means.

The development provides a good passive design approach through material selection (high performance thermal envelope). Where possible, apartments are cross ventilated and well shaded from harsh east and west direct solar gains.

Design Approach

A new design approach that reflects the Australia Dream of the 21st century.

The proposed development is consistent in providing the Australian Dream of the 21st century as follows:

It responds to social equity in a much greater way than that of freestanding housing within the area;

It is consistent with the principles of urban consolidation.

Transition to a carbon neutral future

Responding to the future needs of building design by bypassing infrastructure that may become redundant in the lifecycle of the building (such as gas) due to its inability to operate as carbon neutral.

The development seeks to integrate a Solar PV system to offset the generation of fossil fuel derived electricity and lower grid peak demand.



Construction and Building Management

In order to maximise operational efficiency and longevity, commissioning of plant equipment and ongoing maintenance is required at regular, predetermined intervals. Significant savings in energy and water can be achieved through routine maintenance. The following list is provided to raise awareness amongst buildings owners, owner’s corporations and residents. This list is in no way exhaustive but provides insight into the typical ongoing roles and responsibilities of relevant parties. Objectives

To encourage a holistic and integrated design and construction process and ongoing high performance.

Actions

CONSTRUCTION AND BUILDING MANAGEMENT ACTIONS

Developer/Owners Corp. Responsibilities

Provision of comprehensive pre-commissioning, quality monitoring and building tuning for all building services in accordance with CIBSE and ASHRAE (for mechanical systems) guidelines will be the responsibility of the development team. This is in line with the Green Star Design & As-Built tool credit criteria ‘Building Commissioning’ and ‘Building System Tuning’. The following specific items will need to be maintained by the owners corporation:

Rainwater tank and pump equipment maintenance Centralised hot water system Solar PV System

Property Owner Responsibilities

The following tasks are to be undertaken by the property owner:

manufacturers recommendations

Building User’s Guide

A Building User’s Guide will be provided to all occupants explaining the correct use of installed equipment and building systems. This shall cover at a minimum:

Energy and Environmental Strategy Monitoring and Targeting Building Services Transport Facilities Materials and Waste Policy Expansion/Re-fit Considerations References and Further Information



Emissions

CO2, although significantly contributory to environmental depletion, is not the only form of emissions stemming from the construction of the built environment. Pollution from stormwater, lighting, chlorofluorocarbons and hydro chlorofluorocarbons also negatively affect the natural environment and contribute to global warming. Objectives

To reduce the release of ozone depleting substances into the atmosphere.

Actions

EMISSIONS ACTIONS

Ozone Depleting Potential Materials

Ozone depleting substances are chemicals and compounds which deplete the ozone layer. All refrigerants used on the site will have an ozone depleting potential (ODP) of zero. In addition to this, all thermal and acoustic insulants will be both zero ODP in manufacture and composition. This is in line with the Green Star Design & As-Built credits ‘Refrigerant Impact’.



4 APPENDICES

Appendix A: Bess Assessment



Appendix B: Water Sensitive Urban Design

As described in the SMP the stormwater collected off the upper ground paved area will be treated using a gross pollutant trap (GPT). Since this treatment type is not included in the STORM tool, the equivalent area of infiltration sand is determined following the methodology described below.

The GPT will need to achieve a Nitrogen removal rate of >60%, this is equivalent to a treatment % of 133. The treatment % is the improvement in nitrogen removal compared to the baseline of 45% removal rate prescribed by the STORM tool.
