1 INTRODUCTION

1.1 PURPOSE OF REPORT

This report describes the ESD strategy for the Sydney Modern Project (SMP) at the Art Gallery NSW (AGNSW) for the purposes of the State Significant Development Application (SSDA).

This report identifies the project goals for sustainable performance, the key principles that underpin sustainability and the initiatives by which it is embedded in both the design and the proposed operation of the Gallery.

1.2 PROJECT BRIEF

The Sydney Modern Project at the Art Gallery of New South Wales has the following vision:

From its base in Sydney, the Art Gallery of New South Wales is dedicated to serving the widest possible audiences a centre of excellence for the collection, preservation, documentation, interpretation and display of Australian and international art, and as a forum for scholarship, art education and the exchange of ideas.

The Art Gallery of New South Wales (AGNSW) is also driving the following initiatives:

Conservation of art collection— incorporating a design which allows an area to provide excellent indoor environment quality to suit the art in the space at any point in time.

Integration and multi-functionalism—A holistic and integrated approach which builds on increased awareness of site opportunities, form and function to address a broad range of sustainability objectives.

Green Walls and Roofs—the integration of landscape onto walls and roofs to offer a diverse range of spatial and microclimatic opportunities, giving consideration to the risks associated with water features above Gallery spaces.

Fittings and Fixtures—to be selected and utilised to reduce energy and resource costs, including in manufacture, operations and in recycling at end of life.

Water Efficiency / Harvesting—Integration of water capture and reuse systems into design.

Passive and active design —the design will explore ways to integrate innovative solutions to the following:

Spatial innovation to minimise energy, achieve display conditions without compromising display flexibility.

Increased energy efficiency.

Daylight harvesting for improved indoor environment quality and reduced reliance on electric lighting.

Utilising renewable energy.

Efficient use of reused and potable water.

Reduce or eliminate toxic and harmful substances on the site.

Improved interior and exterior working environments for increased productivity and health.

Maintain visual amenity

Use of natural resources efficiently.

Selection of materials, systems and products based on lifecycle environmental impacts

Increased use of materials and products with recycled content.

Reduce harmful waste products throughout construction.

Use maintenance and operations practices that reduce or minimise harmful effects on people and the environment.

Provision of cardboard, glass and paper recycling spaces.

Installation of an ancillary seawater heat exchange system to act as the new building’s cooling system, adjacent to and within Woolloomooloo Bay;

Diversion, extension and augmentation of physical infrastructure and utilities as required.

1.4 SEARS REQUIREMENTS

The most recent Secretary’s Environmental Assessment Requirements (SEARS) were provided on 8 June 2016 for the Sydney Project. Refer to Table 1 for a list of the requirements relating to Ecological Sustainable Development and a cross reference of where they are addressed in this report.

1.5 BIZOT REPORT

The BIZOT Report is an assessment of environmental standards for the conservation of art developed in 2014.

In the absence of a shared global standard on environmental sustainability for museums, it represents the current best practice in balancing environmental sustainability and conservation priorities for galleries and museums.

Specifically, it identifies a range of internal conditions that are wider than previous international practice and proposed as acceptable for inter-intuition lending.

Furthermore, it identifies a range of energy intensity benchmarks against which the SMP will be assessed.

1.6 LIMITATIONS

This analysis is based on the best available information at the time of assessment.

The Green Star targets do not imply that certification has been achieved. The project is registered for a Green Star rating, but final certification depends on third party assessment of Design and As-built Documentation.

Final performance of the building and its systems will depend on its final design, implementation and operation.

Detail how ESD principles (as defined in clause 7(40 of Schedule 2 of the EP&A Regulation

2000) w ill be incorporated in the design, construction and ongoing phases of the development.

The principles of ecologically sustainable development are as follow s:

(a) the precautionary principle, namely, that if there are threats of serious or irreversible

environmental damage, lack of full scientif ic certainty should not be used as a reason for

postponing measures to prevent environmental degradation. In the application of the

precautionary principle, public and private decisions should be guided by:

(i) careful evaluation to avoid, w herever practicable, serious or irreversible damage to the

environment, and

(ii) an assessment of the risk-w eighted consequences of various options.

(b) inter-generational equity, namely, that the present generation should ensure that the health,

diversity and productivity of the environment are maintained or enhanced for the benefit of

future generations.

Section 2 All categories

(c) conservation of biological diversity and ecological integrity, namely, that conservation of

biological diversity and ecological integrity should be a fundamental consideration.Section 2.1 Land Use and Ecology

(d) improved valuation, pricing and incentive mechanisms, namely, that environmental factors

should be included in the valuation of assets and services, such as:

(i) polluter pays, that is, those w ho generate pollution and w aste should bear the cost of

containment, avoidance or abatement,

(ii) the users of goods and services should pay prices based on the full life cycle of costs of

providing goods and services, including the use of natural resources and assets and the

ultimate disposal of any w aste,

(iii) environmental goals, having been established, should be pursued in the most cost effective

w ay, by establishing incentive structures, including market mechanisms, that enable those best

placed to maximise benefits or minimise costs to develop their ow n solutions and responses to

environmental problems.

2 ESD PRINCIPLES AND PERFORMANCE

2.1 SITE, LANDSCAPE AND URBAN ECOLOGY

The site selection for the Sydney Modern Project is a foundational contributor to the sustainability strategy. The new project is situated on:

Partially over the land bridge partially over the Eastern Distributor Highway; and

Completely over former WWII fuel bunker adjacent to Lincoln Crescent.

Both elements are covered by a thin layer of soil and a mono culture of lawn with a few trees.

The new gallery spaces are embedded within a structured mostly native landscape supporting a biodiversity node with diverse botanical species selection. The integration of green infrastructure with the landscape provides micro-habitats for a broad range of fauna and supports the broader biodiversity of the Domain in a manner that the existing lawn is unable to.

Green infrastructure is the engineered approach to landscape that provides communities with effective storm-water management systems – regulating both the quantity and quality of overland flows while also providing high amenity public space and local ecology hotspots. Green infrastructure – also referred to as water-sensitive urban design (WSUD) – is composed of a wide range of urban water management practices:

Erosion & sediment control

Rainwater tanks

Swales

Green roofs

Constructed wetlands, infiltration systems

Water harvesting and reuse schemes

The location of the new gallery on existing infrastructure and enhancement of local ecological value play to Precautionary Principle and support the climate resilience strategy for the Sydney Modern Project.

2.2 INDOOR ENVIRONMENTAL QUALITY AND CONDITION CONTROL

HEALTHY FOR ART

The provision of an exceptional indoor environment for the storage and exhibition of art is of primary importance for the Gallery.

Achieving a design that meets the lending criteria of the world’s leading art institutions, while also embedded energy efficiency and natural light into the gallery are important considerations for the SMP.

There are three over-riding indoor environmental quality considerations including:

Natural light | Providing natural light, while mitigating the impact of light on art

Temperature Control | thermal stability and conditioning

Humidity Control | hydroscopic stability and conditioning

DESIGN PRINCIPLES

The design principles for providing an indoor environment that is healthy for people and meets the requirements for art conservation are:

Façade that balances natural light admission and control

HVAC system and controls to provide sufficient fresh air and stable climate conditions

Lighting strategy that is integrated with the natural light approach.

Provision of thermal mass to surround close control galleries

Insulation in addition to minimum code requirements

The design is underpinned by the outcomes of the BIZOT report, which identify how flexibility can be introduced into spaces for art.

The BIZOT report also provides for a global benchmarking framework for the combination of condition control and energy efficiency.

DESIGN CONSIDERATIONS:

The key design considerations which inform the indoor environment are:

Glazing selection (recommended VLT < 50%) or secondary screening if glazing has VLT > 50%

Provision of blinds to control direct sunlight

Provision of gauze curtains to manage daylight

Space planning, embedding close control zones within broader control zones rather than direct exposure to the external environment

Dual mode conditioning which is able to provide close control when required, and broader control when not required

Partitioning to separate close control zones from broader control zones for night-time fresh air set-back

The proper control of fresh air in gallery spaces and associated condition and humidity risk that it brings.

HEALTHY FOR PEOPLE

Beside the requirements for art, the SMP is also a space for people. There are a number of critical considerations for how the experience and health of visitors and employees is supported through the design:

Visual and physical connection to the outside environment;

Thermal comfort in both naturally ventilated and air-conditioned spaces through excellent solar control;

Low-pollutant finishes (VOCs & formaldehyde);

Visitor spaces with high air quality;

Transition from the outside environment through thresholds of increasing climate control to fully controlled;

Careful spatial transitions to maintain visual comfort without suddenly exposing visitors to bright light;

2.3 RESOURCE EFFICIENCY | ENERGY AND CARBON

DESIGN PRINCIPLES

The energy performance for the SMP has been benchmarked against the existing gallery performance, a global peer group of galleries and the findings of the BIZOT report into gallery conditioning and energy efficiency.

The energy efficiency and carbon emissions reduction strategy for the SMP is underpinned by a number of primary principles:

High performance building fabric – insulation, thermal mass and glazing

Natural light and daylight harvesting

Set-back air-conditioning for all spaces to avoid over-conditioning when not required

Efficient HVAC and lighting equipment selections

Thermal hierarchy spatial planning - layering tightly controlled spaces within less closely controlled spaces.

In spaces where conditioned control is not required, natural ventilation and mixed mode systems have been allowed for.

CONCEPT DESIGN PERFORMANCE

The initial analysis of the energy performance has been undertaken in conjunction with the NCC section J JV-3 methodology. Analysis has shown substantial sensitivity to the amount of fresh air supplied to the galleries. Design analysis has been undertaken to show the energy benefit of supplying fresh air according to an international ventilation standard specific for gallery spaces (ASHRAE 62.1) rather than the conventional Australian ventilation practice (AS1168).

The energy performance of the baseline model (DTS faced and services); compliance model (Proposed Façade and DTS Services) and the Design model are identified in the adjacent figure.

All are referenced against the BIZOT performance averages and the existing gallery performance.

SUMMARY

The proposed building facade and services are shown to comply with the performance requirements of the NCC Section J by the JV-3 methodology.

The proposed gallery achieves an energy efficiency improvement of approximately 20% compared to the ASHRAE 62 reference building.

The modelled performance corresponds with the median BIZOT performance benchmark and substantially reduces the energy intensity benchmark of the current gallery.

Further improvement is likely with design opportunities in optimising heat recovery and the treatment of the substantial fresh air load.

The energy analysis to date does not take account of on-site generation, which is dealt with in following sections.

RENEWABLE ENERGY AND GREEN POWER

On-site renewable energy and the procurement of low-carbon electricity is a priority for the Gallery.

A range of options have been considered, including:

Building Integrated PV integrated with some of the SMP pavilion roofs

Procurement of Green power.

A benchmarking study has been undertaken and referenced against the existing gallery energy consumption data for the following options.

A mix of conventional PV and Building Integrated PV (providing in the order of 250kW, 1000m2)

Purchase of zero-carbon power (GreenPower equivalent to conventional PV output)

The cost-benefit analysis indicates that conventional PV provides the best whole-of-life performance; BIPV provides the best aesthetic solution and the purchase of GreenPower provides the greatest scope for deep carbon emissions reduction, but at the highest cost.

ENERGY EFFICIENCY OPPORTUNITIES

Many further energy efficiency measures (EEMs) have been loosely or actively considered for the SMP.

The analysis work to date has identified several EEMs that have a high potential to significantly reduce energy use or increase thermal comfort and the stability of internal conditions.

The EEMs that are now under further study are:

Architecture

Enhanced architectural shading (broader overhangs, lower SHGC glazing)

Heating, Ventilation and Air-Conditioning

Ventilation heat recovery (sensible and enthalpy for further dehumidification)

Heat recovery cooling plant

Labyrinth thermal storage and OA pre-treatment

Controls

Gallery night setback of supply air volume

Gallery climate conditions loosened for a portion of the year.

2.3.1

2.4 RESOURCE EFFIENCY | WASTE AND MATERIALS

DESIGN PRINCIPLES

The design principles for waste and materials at the SMP are:

Reducing the resource and climate intensity of the major building fabric materials;

Reducing toxicity in building materials and finishes for a healthier indoor environment and mitigating disposal pollution risks;

Avoiding the use of materials that deplete non-renewable resources;

Supporting a whole-of-life or chain-of-custody approach to material procurement.


The key waste and materials considerations which inform the design are:

Use on non-cementitious materials in concrete

Increased recycled content in steel

FSC-certified timber

Avoidance of PVC where possible, and use of PVC complying with best practice standards where it must be used.

The Gallery is exploring a range of operational materials and waste considerations for managing the substantial material consumption associated with exhibitions.

Considerations include:

Cradle-to-grave or cradle-to-cradle stewardship requirements in materials procurement; and

Durability requirements for temporary gallery walls to allow for greater in-house re-use.

Other opportunities for closed-loop approaches to waste include:

Food-waste to compost for landscaping

Environmental Product Declarations for fit-out and finishes; and

Local sourcing.

2.5 RESOURCE EFFICIENCY | WATER

DESIGN PRINCIPLES

The design principles for the integrated management of water for the SMP are:

Water consumption is reduced as far as possible through efficient equipment, fitting and fixture selections;

The majority of non-potable water demand (existing gallery cooling towers) to be met through captured rain- and storm-water and/or recycled water;

Harbour heat rejection allows for no new cooling towers being installed, saving 6.3ML/year.

The landscape to provide local ecological hot-spot through regenerative native landscaping that integrates with the water cycle; and


The key design considerations which inform the integrated water cycle management plan are:

Best practice fittings, fixtures & appliances (low-flow fittings, dual flush toilets);

Rainwater capture from all rooftops for re-use in existing cooling towers;

200kL rainwater storage tank for use in existing cooling towers;

150KL rainwater storage tank and 150KL stormwater detention tank for onsite irrigation;

Harbour heat rejection in lieu of evaporative cooling towers for the Sydney Modern Project conditioning systems to reduce to reduce water demand for the new gallery spaces – potentially reducing 6.3ML/year.

Future considerations include collaboration with other institutions to assess the feasibility of resource sharing. Specific opportunities include The Royal Botanical Gardens, Eastern Distributor storm-water management (RMS), State Library, NSW Parliament House and other neighbouring State Government agencies.

FIXTURES AND FITTINGS

A simple way to reduce potable and recycled water consumption is through the use of efficient fixtures and fittings. The design team anticipates specifying fixtures with the following Water Efficiency Labelling and Standards Scheme (WELS) performance levels:

Showers – 3 Star WELS rating, 6.0L/min

Taps – 6 Star WELS rating, 4.5L/min

Pans – 5 Star WELS rating, 3.0L/flush

Urinals – 6 star WELS, ,0.8L/flush

Dishwashers – 6 Star WELS rating, 9.8L/cycle

STORMWATER QUALITY

There is an opportunity to address the quality of the storm water entering the public infrastructure. An efficient filtration system including landscape elements is being designed and implemented to ensure that the water is of a high quality and will not cause adverse environmental impacts downstream. Typical pollutants present in storm-water vary depending on the run off surface.

The target pollutant reduction for the SMP is:

Total Suspended Solids to 90%

Gross Pollutants to 95%

Total Nitrogen to 60%

Total Phosphorus to 70%

Total Petroleum Hydrocarbons to 90%

Free Oils to 98%.

2.6 EMISSIONS AND POLLUTION

DESIGN PRINCIPLES

Reducing the polluting emissions from the SMP are a priority. The direct emissions from the site have an impact on the ecosystems of Woolloomooloo Bay and the local ecosystems in the Domain and Royal Botanic Gardens, including extensive nocturnal avi-fauna (bats and birds).

The principles for pollution reduction respond directly to these sensitive ecosystems and are:

Stormwater quantity and quality management with water sensitive urban design and collection tanks;

No artificial light directed into the night sky;

No new cooling towers due to harbour heat rejection, so reduced legionella risk.

2.7 TRANSPORT AND MOBILITY

DESIGN PRINCIPLES

The SMP includes provision for improved public access and reduced reliance on cars for staff and visitors alike.

The key principles for mobility are:

Effectively connecting Woolloomooloo to the city;

Providing minimal car parking;

Providing extensive bicycle storage for visitors and staff; and

Providing end-of-trip facilities for staff.

The project is well connected to the CBD by key pedestrian links, with good walkability to Martin Place and St James stations.

Disabled access through and across the site is of particular importance and the SMP plays a crucial role in providing equitable access to the galleries as well as across the site.

2.8 CONSTRUCTION AND OPERATIONAL MANAGEMENT

CONSTRUCTION MANAGEMENT

There are a number of important considerations in the construction management for the SMP. While the procurement of a building contractor is yet to commence, there will be a number of core requirements embedded within the procurement documentation:

Environmental management (ISO14001 and a compliant EMS)

Best practice commissioning and building tuning

Contractor Education for sub-contractors

Detailed metering and monitoring systems (during construction and operation)

INSTITUTIONAL SUSTAINABILITY

Furthermore, the Gallery is exploring institutional opportunities to further embed sustainability principles in the operational management of the SMP:

Financial Transparency – disclosure of the sustainability costs for the project to the Green Building Council of Australia to inform industry development

Institutional commitment to operational and end-of-life waste performance

Culture, Heritage and Identity – embedding interpretation of contemporary and indigenous culture, heritage and identify within the SMP project;

Local Procurement

2.9 RESILIENCE

CLIMATE CHANGE

Climate change is a critical consideration for long-term projects, especially in coastal areas.

Key climate considerations include:

Flood thresholds at Lincoln Crescent to take account of the 2100 climate change sea level rise projections (passive and active mitigation options are available).

Location of critical electrical infrastructure and emergency generation to above 2100 flood levels to maintain systems in the event of substantial flooding events;

Passive building performance to provide thermal stability for artwork in the event of elevated temperatures or utilities disruptions.

Furthermore, the detailed design of the pavilion roofs will take the potential for higher-then-usual wind loading in line with predicted climate change impacts.

A detailed climate adaptation plan will be undertaken in subsequent design phases to identify the detailed design considerations to mitigate these key climate risks.

3 GREEN STAR ASSURANCE AND CERTIFICATION

3.1 GREEN STAR DESIGN AND AS-BUILT

Green Star Design and As-built is an industry tool for benchmarking sustainability performance for the built environment.

The SMP is registered for a Green Star rating with the Green Building Council of Australia. The project is seeking a 5-star rating through a mix of design and construction sustainability initiatives.

Furthermore, the options to exceed the 5 star rating are being considered through the procurement of low-impact goods and low-carbon energy.

The 5-star strategy is noted in the scorecard in Appendix A and summarised in Table 2 below.

(i) polluter pays, that is, those w ho generate pollution and w aste should bear the cost of

containment, avoidance or abatement,

(ii) the users of goods and services should pay prices based on the full life cycle of costs of

providing goods and services, including the use of natural resources and assets and the

ultimate disposal of any w aste,

(iii) environmental goals, having been established, should be pursued in the most cost effective

w ay, by establishing incentive structures, including market mechanisms, that enable those best

placed to maximise benefits or minimise costs to develop their ow n solutions and responses to

environmental problems.
