Executive Summary
This report outlines the Ecological Sustainable Design (ESD) strategy for the proposed resort development located at Serenity Close, Noosa,
Queensland. The proposed project will be a luxury resort complex providing high end short stay accommodation, retail, restaurant and leisure
facilities. The priorities of the project is to seek resilience, sustainability, guest comfort, and a balance between the public, private and natural
environments.
The development location falls within the Noosa Council local area boundary.
While there are no direct sustainability planning requirements or metrics to be achieved, the development team is cognisant of the sustainability
initiatives within the Noosa Plan 2020 and Noosa Council’s sustainability commitments, including their Carbon Neutral target.
Noosa Council Sustainability Principles:
1. Resources are sustainably managed so that the lifestyle of the community is preserved, without compromising the ability of future generations
to meet their own needs.
2. Noosa’s economy is prosperous, diverse and protective of its unique environment.
3. Noosa residents belong to a community that values its diversity, accessibility and affordability.
4. Noosa’s community is inclusive, connected and resilient and encourages participation and information sharing.
5. Noosa’s community benefits from quality places and programs that enhance wellbeing and support creative, active and healthy lifestyles.
6. Good governance is achieved through effective and efficient decision making, made in the interests of the community.
With regard to the project climate change response, climate change mitigation and adaptation will be incorporated into the design:
▪ climate change "mitigation", refers to efforts that reduce greenhouse gas emissions or enhance carbon sinks

2.0 Climate Change Mitigation
To mitigate further impacts of climate change the development plans to be designed and operate in a manner to reduce carbon emissions
related to energy consumption, waste, water, construction materials and transportation.
2.1 Energy Efficiency
It is well established that the energy use of a building is generally the greatest contributor to greenhouse gas emissions. The following
sections set out design strategies utilised for this development to reduce the building’s energy demand and greenhouse gas emissions.
2.1.1 Shading
Shading is a critical component of the building design. Large overhangs, both vertical and horizontal, will be incorporated, and the north
facing glazing should aim to reduce the amount of direct solar radiation for all times during the year. The development provides shading to
the glazed facades by means of extended floor plates, shading and semi-enclosed balconies.
2.1.2 Glazing and Fabric Performance
The proposed high-performance glazing provides solar control to prevent summer heating while allowing useful passive solar heating in
winter. The low U-value of the glazing would minimise the conductive loss or gain. These result in an improved thermal comfort, improved
energy rating and subsequently a reduced overall carbon footprint of the development.
Similarly, thermal bridging is the transference of heat through a wall at a point through which it can bypass the insulating layers of the
structure. It is through these points in a building’s envelope that they can experience unwanted heat gains and/or losses and as such should
be considered when designing for sustainability and energy efficiency. The architectural and structural detailing on the project will consider
the issue of thermal bridging and will apply design principles to avoid unwanted heat losses or gains wherever possible through thermal
breaks and other measures.
2.1.3 Airtightness
Airtightness is the fundamental building property that impacts infiltration and exfiltration - the uncontrolled inward and outward leakage of
outdoor air through cracks, interstices, or other unintentional openings of a building, caused by pressure effects of the wind and/or stack
effect. The development will be designed with airtightness in mind for architectural detailing and specification to limit air leakage from the
building envelope elements such as glazing systems and external walls.
2.1.4 Air Conditioning
Following the reduction in the thermal loads, an efficient air
conditioning system will be included in the development. This
system has been chosen for its ability to only operate on a room
by room basis. This means that when rooms are un-occupied,
they can be complete switched off, unlike larger systems which
will have minimum operational requirements.
These systems will be coupled with a smart room control
system which will ensure the rooms aren’t overtly conditioned
when unoccupied or when the rooms are operating in natural
Figure 1: Room control system
ventilation mode.
2.1.5 Lighting
All lights will be fitted with light emitting diodes (LEDs), including lighting in the corridors, stairwells, garage, and external lighting. The room
lighting will be coupled with a smart room control system which will ensure the rooms aren’t lit when unoccupied. All common area lighting
will incorporate light controls such as occupancy sensing (PIRs) and time switches to reduce lighting consumption when lighting is not
required.

7 2.1.6 Equipment The room appliances and equipment will be selected to be energy efficient and have shut-down or sleep options for when in use to minimise energy waste and heat loads building up in the rooms. 2.1.7 Pools The provision of pools can be a major source of energy consumption for treatment, filtration and heating. The selected pool systems will focus on energy efficiency with core consideration of the pool temperatures and the use of pool blankets to save energy when not in use, should operational issues be resolved. 2.2 Energy Sources Solar photovoltaic (PV) panels will be installed on-site to supply power to the development and the electricity grid. The roof will be designed to allow for a maximised array. The development also aims to use 100% renewable energy sources (Green Power) from grid purchased electricity. Figure 2: Available roof area for PV 2.3 Waste Management The main objectives for waste management strategies for construction and operational are to ensure that waste is avoided and recycled during design, construction, and operation.

Waste within the building construction context can be avoided by encouraging the selection of lower-impact and long-term materials.
Operational waste to landfill can be reduced by providing relevant and easily accessible facilities for recyclable waste and other waste that
can be diverted from landfill such as organic waste, batteries, or e-waste.
A dedicated waste storage area will be provided for the separation and storage of recyclable waste during operation, allowing for the
different waste streams to be separated to match the local recycling scheme. At least three streams will be covered including landfill,
recycling and a third stream which may be organic/food waste or other high impact waste stream.
Throughout project design, operation and construction, principles of resource recovery will be applied, so that materials and products are
recovered and reused where possible, reducing landfill and saving money. Some strategies that will be investigated include:
▪ Innovative waste separation and collection strategies to allow materials to be isolated for reuse in the circular economy;
▪ A purchasing policy which aims to minimise waste from products and packaging, encourage the use of products which have minimum
environmental impact; and
▪ Manufacturers and suppliers will be encouraged to take full responsibility for the life cycle impact of products including ownership at
end of life.
The development will explore the possibility of recycling all forms of food and organic waste by identifying waste streams and incorporating a
strategy that reduces food or organic waste going to landfills. Organic waste will be processed on site and utilised within on-site vegetable
gardens where possible.

2.4 Water Management
Southeast Queensland is susceptible to periods of drought, along with period of excessive rainfall. Minimising consumption during all
periods is critical to maintaining a viable water resource, and minimising carbon emissions
The following table summarises the specific initiatives included in the design in relation to water efficiency:

water uses will be carried out
▪ Pool water saving features like rainwater flush and pool covers will be reviewed
Pools and water features
▪ Pool temperatures will be managed to minimise energy and water wastage
2.5 Transport
Sustainable projects should facilitate a reduction on the dependency of
occupants on using a private car and is an important means of
reducing overall greenhouse gas emissions. The use of motor vehicles
directly contributes to climate change through the direct emissions that
result from car operations.
The hotel will provide the following initiatives to promote sustainable
transport options:
▪ Share bicycles for guests to utilise around Noosa
▪ Electric vehicle charging infrastructure to promote guest to use
electric vehicles
▪ Electric town car charged via renewable energy for zero
emissions transfers and resort guest usage
▪ Electric solar powered shuttle boat to ferry people to and from
Hastings Street, reducing emissions, idle time and congestion in
Noosa. Figure 4: Solar power transportation option
2.6 Construction and Materials
Buildings consume considerable natural resources in their construction, operation and demolition. The building will aim to reduce the total
embodied energy and carbon in the construction materials. Materials for the construction of the development will be sourced from suppliers
located as close as possible to the site to minimise the carbon footprint related to transportation. The materials used in the construction of
the complex are capable of being recycled in the future.
Table 2: Construction and materials opportunities
Design Focus Intended Design Initiative
▪ The building design and material selection will reduce the extent of environmental impact as much as possible
▪ Workshops during design will be conducted to benchmark the impacts and investigate lower impact materials
Embodied carbon in the
building materials ▪ Material purpose will be considered for how the architectural intent can be achieved while minimising structural
and materials impact
▪ Design optimisation will be reviewed to achieve standard lengths and efficiencies, reducing waste
▪ Concrete mix designs will focus on reducing cement content

3.0 Climate Change Adaptation
Adaptation to the changing climate is being considered to manage the project’s operational risk, details of which will be assessed following
Development Approval. Typical design amendments to manage this risk include:
▪ Increased air condition system design temperature to increase capacity.
▪ Increased rainwater capture sizes to provide increase capacity for periods of drought, noting tank sizing to cover through entire
periods of drought is impractical.
▪ Increased capacity of roof gutter, downpipes and civil infrastructure to manage increases in rainfall intensities.
▪ Review and design of surface areas to manage rainwater overflow in peak rainfall events.
▪ Review of roof gutters and downpipes for hail and debris build-up and overflow analysis.
▪ Consider increased storm events with high wind gusts to inform design, outdoor furnishings and operational management.
▪ Locate critical building equipment like switchboards, emergency systems, pumps and critical HVAC away from openings (including
weatherproof louvres) and away from potential flooding risk.
▪ Review basement car park areas for flood risks.
▪ Fire and ember management plans and consideration of Bushfire Attack Level in the future.

4.0 Healthy and Comfortable Spaces
The provision of healthy and comfortable spaces within buildings aims to achieve sustainability performance improvements in a manner that
also improves occupants' experience of the space. Sustainable buildings are designed for people and reductions in energy use should never
be made at the expense of the occupants' health and wellbeing.
A holistic approach to sustainability will result in multiple benefits both in energy efficiency and encouraging occupant wellbeing. This can be
achieved by improvements to air quality through appropriate ventilation, the provision of high levels of thermal, visual, and acoustic comfort,
reduction of occupant stress and the creation of a low-toxicity environment through the reduction/removal of pollutants.
4.1 Thermal Comfort
An indoor environment that is too hot or too cold can affect mood, performance, and productivity. To control internal comfort and minimise
excessive heat loss in winter and heat gains in summer, several strategies will be investigated for the proposed development. The following
points shall be considered when designing the Resort:
▪ Façade design and glass selection; heat gains and losses must be moderated, and thermal bridging should be avoided. Double
glazing systems will be considered for this development to improve the thermal performance of the building envelope.
▪ The façade should be well sealed to avoid drafts and air leakage.
▪ External shading and cool winds with single sided ventilation prevent excessive heat gains in summer.
▪ A relatively high total insulation level for all rooms to capture heat and minimise heating loads to aid building performance in winter.
4.2 Toxicity
Volatile organic compounds (VOCs) are emitted from certain solids or liquids as toxic gases. VOCs include a variety of chemicals, some of
which may have short- and long-term adverse health effects. Concentrations of many VOC’s are consistently higher indoors than outdoors.
VOCs are emitted by a wide array of products numbering in the thousands (typically paints and lacquers, paint strippers, cleaning supplies,
pesticides, building materials and furnishings).
The development will aim to specify materials with low emissions content including low-VOC and low formaldehyde content to avoid
contaminating the indoor air environment.

4.3 Natural Ventilation
It is proposed that the rooms within the development achieve natural ventilation through their large operable sliding doors and balconies.
The large window to floor area ratio, and balcony design will protect the rooms from prevailing winds enabling longer periods of time where
the rooms can be in natural ventilation mode.
4.4 Nature Connectivity
Appropriate daylight is essential for users’ wellbeing, connection to the outdoors and for energy efficiency. However, excessive daylight can
cause glare which should be avoided. The rooms shall be designed to have large sliding doors with large balconies to maximise daylight
levels while reducing glare. This will provide the users with the option of utilising the internal or external environment.
The following design opportunities are considered throughout the detailed design process to maximise the daylighting potential:
▪ Given the extent of proposed glazing, glass with a moderate visual light transmittance (VLT) allows sufficient daylight to penetrate the
space.
▪ Light internal colours improve indoor lighting levels.
The provision of the glazed elements will enable connection to nature either within the resorts abundant landscaping or with views out over
the surrounding bushland.
Additionally, all external landscaped spaces will only be illuminated by downward facing light fittings to reduce the negative effects of light
pollution.

15 5.0 Urban Ecology With continuously growing cities, urban ecology plays a large role in conserving biodiversity and improving the quality of life for urban residents. Well planned buildings and landscape architecture not only protects and enhances biodiversity, but it also enables sustainable landscaping, such as low water use, low fertiliser requirements and local native and indigenous plant species selection. If possible, remnant indigenous plant communities should be managed and protected. 5.1 Heat Island The heat island effect describes the condition where urban areas have a higher average temperature than its rural surroundings due to the built environment's makeup. The use of light coloured roof materials, solar panels, water features, combined with shaded and landscaped areas, can significantly reduce the heat island effect, and contribute to further energy savings. 5.2 Vegetation Vegetation selection is critical to the success of the project to ▪ Provide the right atmosphere ▪ Minimise water demand ▪ Promote native fauna ▪ Integrate with the surrounding environment Figure 9: Heat island management through vegetation and light surfaces ▪ Provide a manageable level of maintenance ▪ Be safe for guest engagement The vegetation for the development will be carefully considered to achieve this balance. 5.3 Light Pollution Light pollution is an environmental issue that is becoming more of a problem every year as cities continue to grow in both size and population density. Excessive amounts of light being projected upwards is not only a waste of energy and resources but has also been proven to have a negative impact on the local wildlife by affecting various species’ vision, mating, nesting, and built-in migration instincts. Similar effects have been found in humans, with some people struggling to sleep and relax with prolonged exposure to artificial daylight and glare from poorly fitted external lights. The idea of reducing light pollution through sensible light fittings can save the site owners financially by reducing wasted energy and increasing lighting efficiency whilst simultaneously contributing positively to the health and wellbeing of the surrounding natural environment. The project targets to have all external light fittings pointing downwards, mitigating the effects of light pollution. The Calile Hotel, Noosa | Sustainability Strategy | RPT-SY-001 | 1036421
