2        Overview of Site & Buildings
         Warringah Mall is one of Sydney’s Northern beaches leading regional shopping centres. Located
                                                                                          th
         approximately 15km’s from the CBD, being first opened for business on 4 April 1963. The
                                                     2
         existing centre is comprised of 125,000m of retail space and 295 stores on three levels. The
         precinct is a mix of casual open courts, covered walkways and some fully enclosed mall areas
         with locals noting wide walkways, lush foliage and native trees in the precinct.

         Warringah Mall currently features 4,468 controlled parking spaces, including 1,300 undercover
         spaces. The centre is currently easily accessible by public/private transport having an internal
         bus bay and a dedicated state transit bus stop on the perimeter, Pittwater road.

                                                                            Warringah Mall Master Plan
                                                                      Sustainability Management Plan


3        Climate Analysis
         In order to understand the climate and prevailing weather conditions in Warringah, a climate
         analysis was undertaken using the closest comparable weather data.
         Climatic analysis has been completed to reveal appropriate passive design strategies in the
         proposed Warringah Mall development.


         Thermal Comfort
         Psychometric analysis was carried out to identify modes of passive heating/cooling strategies
         viable in relation to site-specific climatic data. The psychometric analysis visually depicts these
         findings through a series of dots representing conditions during an hour of the year between 8am
         and 6pm, showing a combination of temperature and humidity outside.
         The results of the analysis are as follows:
             The yellow dots indicate that for roughly a third of the year, outside conditions are ideal,
             which could be useful for a mixed mode air conditioning approach.
             The red and orange dots indicate that for a quarter of the year, outside conditions are too
             cold, however, internal heat gains and thermal efficiency of the building fabric will minimise
             the need for heating.
             The purple and lilac dots indicate that humidity is an issue for 10% of the year, and therefore
             cross ventilation will be addressed by the design.
             The lilac and blue dots indicate that for 3% of the year, outside conditions are too hot,
             however, internal heat gains and thermal efficiency will increase this percentage, therefore
             effective cooling will need to be provided where necessary.

                                                                          Warringah Mall Master Plan
                                                                    Sustainability Management Plan


         Wind
         Wind studies were executed for the Warringah site to determine the viability of ventilation
         strategies for Warringah Shopping Centre Extensions. Figure 3.2 shows the average annual
         wind pattern for both Mean 9am and 3pm for the Warringah site.

         Mean 3pm Wind Speed




                          Figure 3.2 Wind Speed Diagram, Climate Analysis Cundall

         From this study there are possibly two scenarios for mixed-mode ventilation. Scenario A (Figure
         3.3) depicts summer afternoon breezes predominantly from the NE, E, SE & S with an average
         Mean wind speed of 17.9km/hr. Scenario B (figure 3.4) depicts Mid-season afternoon breezes
         predominantly from the NE & E with an average Mean wind speed of 19.1km/hr.

Report    S8138                     Revision   C                         Date   01/12/08               Page 7
                                                                              Warringah Mall Master Plan
                                                                       Sustainability Management Plan

         The integration of mixed mode ventilation into the Warringah Shopping Centre extension could
         reduce the total amount of cooling required by 30-35%. Capturing prevailing winds in the design
         from the East (predominantly) and North East will see the reduction of solar energy (heat) build
         up during warm mid season and summer days.


4        Indoor/Outdoor Environment Quality
         Consideration to the sustainability level of the Indoor/Outdoor Environment Quality shall be
         addressed by the design. Sustainability measures to be considered during each phase of the
         Warringah Mall extensions address the following where practical:

             Capturing available daylight through building form and fabric to achieve good natural lighting
             levels to the space both indoor and outdoor, where appropriate;

             Creating a ‘comfortable’ space for the user through integration of mixed-mode cooling
             strategies;

             Selection of materials to reduce glare and visual noise to the existing environment;

             Consideration to external views;

             Consideration to landscaping and retention of existing flora;

             Consideration to the fluidity of pedestrian traffic areas, built spaces and amenities; and

             Minimisation of emissions created from materials and waste.



5        Material and Resource Sustainability
         In addition to fitness for purpose, economy, aesthetics and availability, consideration of
         construction materials that reflect upon the issues of a material’s environmental credibility and
         impact on Indoor Environmental Quality (IEQ), will be given including:

             Construction materials sourced (where viable in overall design) from sustainable sources
             taking into consideration the LCA (Life Cycle Assessment) of the material before
             specification;

             Water based and low VOC materials for finishes and adhesives;

             Where practical encouragement will be given to tenancies to adopt sustainable principles
             listed in this document in individual tenancy fit outs.



6        Water Conservation Strategies
         In light of Australia’s current water crisis the Warringah Mall extension will endeavour to consider
         water conservation, recycling and re use throughout the extension and surrounding Landscape.
         Water conservation can be achieved by a two stage approach: firstly by reducing the inherent
         amount of potable water consumed within the development through demand management, and
         secondly by substituting mains water usage with recycled water into amenities and landscaping
         where practical. The following sustainable techniques will be explored and implemented into the
         extension design where practical and sustainably viable:




Report    S8138                       Revision   C                           Date   01/12/08              Page 8
                                                                             Warringah Mall Master Plan
                                                                       Sustainability Management Plan

                  High efficiency fittings and appliances to reduce mains potable water consumption.
                  Note that the WELS Star rating scheme replaced the AAAAA scheme as of July 2006. A
                  list of rated products can be found at http://www.waterrating.gov.au/;

             Use of water efficient dual flush toilets and low flush/waterless urinals in amenities;
             Showers with integrated reduced flow rate water heads;
             Precedent given to the specification of flora for any landscaping to be that of native origin
             with minimal water consumption;
             Integration of water metering and facilities management plans for excessive water
             consumption through leakages of amenities and hardware;
             Consideration to the availability of using recycled water in all sprinkler, micro spray, sub-soil
             drip system or any other watering system;
             Consideration to Black water and grey water on site treatment; and
             Consideration to Storm water management in accordance with WLEP 2000.



7        Waste Management
         During the design, construction and occupancy phase consideration to the appropriate
         collection, separation and management of waste materials throughout the development process
         of the Warringah Mall should be given. The following strategies will be considered:
            Specification of pre fabricated materials to reduce on site construction waste;
            Establishment of a waste management area on-site for the collection and separation of
            materials;

                                                                         Sustainability Management Plan


8        Social Sustainability
         It is difficult to quantify the value of the social context in the overall environmental sustainability
         of the proposed extension. However as the Warringah Mall is a public space its social context
         has placed importance in the local surrounds and with it, its people. The integration of a
         sustainable, organic extension will address the issues of environmentalism in a space people
         can enjoy and experience. The mall extension will address social sustainability for the Warringah
         area by considering:

             The development of community awareness and involvement in environmental matters
             through cross generation exposure;

             The promotion of community education in sustainable principles and practices;

             The creation of a village-like atmosphere providing a safe and comfortable environment for
             pedestrians meeting the needs of the surrounding area; and

             The provision of an exemplary vernacular in the community for other commercial spaces to
             follow.



9        Energy Consumption and Renewable Energy
         Energy reduction and conservation through passive and non passive measures is principle in the
         ongoing sustainability of the Warringah Mall proposed extension. Energy efficiency can be
         achieved through key sustainable strategies from design of the built form to operation and
         management of facilities during occupancy. Key strategies to be considered in the design
         development phase for the proposed extension are:
             Passive design to minimise the need for mechanical heating and cooling of spaces;
             Integration of shading devices and ventilation of facades to reduce solar energy loads at
             high luminance periods of the day;
             Using an architectural design to harness natural light into spaces where practical through
             integration of light wells, sky lights and voids to reduce lighting energy consumption;
             Integration and specification of efficient luminaires and lamps to reduce overall energy costs
             as well as integration of smart metering and sensoring of lit spaces will help to minimise
             energy consumption from lighting;
             Selection of efficient cooling systems integrated with a mixed-mode strategy to create
             efficient thermal comfort for the user and minimise cooling demand.
             Sufficient shading to ‘open-air’ spaces to reduce thermal discomfort from movement
             between indoor and outdoor spaces;
             Integration of energy metering by facilities management to address excessive variances in
             energy consumption from practical occupancy consumption;

             Recommendation to tenants of specification of energy efficient appliances in individual fit
             outs with exemplary star ratings of a bench mark minimum practice.; and
             Consideration to integration of renewable technologies where practical including focusing on
             solar hot water generation and integration of photovoltaics.

                                                                             Warringah Mall Master Plan
                                                                        Sustainability Management Plan


10       Ongoing Environmental Site management
         The adoption of an EMP (Environmental Management Plan) during commissioning and over the
         life time development of the infrastructure will be explored for implementation in the Warringah
         Mall extension. Imperative to the successful ongoing sustainability of development is in the
         commissioning and facilities management. Through metering of separate facilities addressed in
         the design, bench mark standards can be produced, adhered to and targeted for improvement.
         It is understood that tenants will have varied commitment levels to sustainability and this should
         be considered when developing EMP guidelines.



11       Air and Noise Pollution
         Warringah Mall extension will endeavour to explore emissions minimisation of the project
         adopting the following strategies where practical:
             All refrigerants and insulants will be considered for their ozone depleting potential;
             Refrigerant leak detection and capture system will be considered to minimise local
             refrigerant emissions; and
             Consideration will be given to external light pollution to minimise night–time impact to the
             community.
