intro

Fitzpatrick+partners was invited in April 2008 by St Hilliers to take part in a Design Excellence Competition for the development of their site in Argyle Street Parramatta. The concept presented is our interpretation of the brief, and in particular: “...to produce a feasible and commercially viable design that is attractive to government and commercial tenants, that responds to the site’s context and constraints and opportunities of the site itself, maximises opportunities for ecologically sustainable design, achieves design excellence and improves the urban domain of Parramatta City.�

HEIGHT AND SHAPE

80 m.

The building has a very good height to have very good views and the orientation is always good because the principal facade is orientate to the north but, it has a lot of daylight the most of the day and the shape is very basic, rectangular plan. It is not proposing and shadow system with the same structure, it is very plan and basic.

THE BUILDING AND THE CONTEXT

ORIENTATION

The building is surrounded by not very tall buildings with 4 or 5 levels therefore do not provide any exterior facade shadows anywhere.

The orientation of the building is NORTH EAST, so we have the cold facade infront but there are not any buulding protecting and it transforms to the hotest.

Arcoustics and visuals floats for pedestrians buses and trains underneath the office levels

NE

The view corridor for the historic statiorn building is reinstated.

VIEWS

The building has incredible views in offices and on the rooftop to the Sydney CBD and historic Parramatta station which will create great importance to these two urban landmarks and makes the top capital gains has more importance and the part down.

Outlook and views are maximised.

All the buildings are not creating any shadow to the building, the sun is directly to the principal facade of the offices, so it is very inconfortable and we will need to use curtains or lattice system to protect offices in the morning because it is the time of begin to work.

Its happening the same effect but now the sun is more direct to the principal facade so we have same problem, it will be a very hot place inside offices and the hotel level too.

In spite of that, we have a very hot offices to be protect. THE WORST HOUR!

N

6:00 PM

All the buildings are making shadows to the principal facade but its not enought because we now have very hot place in the other site, and no too much sense because there is not too much people because offices are closed yet.

Not too much sun light for this our.

Implications for design Ease of access through the site; also a great thoroughfare for wind and daylight.

We would like a bit of sound travelleing through the site so glass and tiles will reflect the sound well.

Important that sound does not leak into the offices from this space. Daylight and Night light will play a theatric feature in this design. High ceiling will allow high cross ventilation to reduce the humidity in the space.

NEW PROPOSAL

BUILDINGSTUDIO COMPOSITION

CIRCULATIONS BAR AND GAMING

PROS 1. We improve the sound levels for each room to have its appropriate level of inner sound and not interfere or disturb others.

2. Improved the main facade of the offices to improve its internal temperature and make a more pleasant work space.

OFFICES

3. Create a lobby with more open and less closed to improve its lighting and temperature and avoid using artificial light in most of the day as it is in the restaurant downstairs and it is difficult for you to get natural light with a roof very it closed as formerly had.

4. Decided to retain the main structure because it is part of the building and work to support the building structurally.

5. Create the use of a double glass as double facade to improve the lighting and temperature.

LOBBY AND RETAIL

6. We play and create a new geometry into the building to create a shutter with the same structure in all of the offices.

7. moved the restaurant to the top as a very public place and create an open and well-lit space also improve sound levels this place.

PRINCIPAL ACCESS GROUND LEVEL

8. We decided to keep the lobby open walls and windows were removed and completely permeable to allow users access from both streets surrounding the building and creating a view of the historic bus station basement was left Parramatta

The agenda of the current building is made up by the lobby at the bottom, followed by the hotel on the top floor and a bar, open to circulate air and above have offices space is left. We decided to change the program of the building and move the bar located in the middle part and move it to the rooftop of the building, and we think that acoustic problems is better to have this space on the top and not interrupt levels sound between the lobby and offices with lower noise levels to be public places, and open the roof of the lobby to promote natural lighting and ventilation of the building.

The offices moved the main facade to promote lighting and the temperature inside the space because as we saw in the last analysis the building is not surrounded by high-rise buildings therefore causes no shade and protects the building from sunlight, this is the reason why we put a double facade Northeast facade of the building and moved her way doing a slice to the right favoring creating shadows and lighting and regulating the temperature above.

The rooftop bar is a pretty good tool and move this program to the top does a more open space and so the sound levels may be higher and not have to worry about the lighting and natural ventilation.

Thermal Analysis There are a few thermal strategies incorporated in this building.

1. Heating and cooling through the ceiling and floor voids.

2. Natural Ventilation across the short distance of the floor plate which also provides fresh air to be returned and cooled or heated.

3. If all the windows in the buildings are closed, this would still function as the system would take flowing air from the void between the Lobby and the Offices.

- The Bar and Gaming area uses the stack effect through its double layer to let heat rise to the top. It is then released by automated openings in the Roof Facade when the temperature increases beyond 23degC or when the humidity is above 50%. Fresh and cool air is channeled from the window openings of the Bottom Floor.

The Bar and Gaming Area is also fitted with the underfloor ad ceiling system but we expect it not to need except in the cases of unforgiving weather such as heavy rain, hail or extreme heat waves.

- The Lobby and Retail Zone utilises the stack effect well to move cooler air through the space and heat out through the perforated ceiling. The changing levels of the ceiling encourages movement of air across its surface. The challenge with such an open space is heating it. For this reason, each space in the Retail area is smaller and has insulated walls & flooring combined with the flooring being raised above the floor slab.

- The Offices relies much more on the heating and cooling system but has break-out spaces that are all naturally ventilated and system free.

Offices: Warmer Weather - The windows can be opened and allow cooler air to flow through and the return system can be activated to remove unwanted heat.

Cooler Weather - Inside the office the Insulation in the floor and walls should be sufficient especially with the appliance & body heat but if it isn’t the underfloor heating can be activated.

Open-Aired Operable Roof Facade

Internal Louvres

Summer Sun

Winter Sun

Breakout Spaces: Warm Weather - Blinds can be opened to let air and daylight pass through the external facade, the windows can then be opened to further the cooling process.

Cooler Weather - External Blinds can be closed to stop wind permeating the 1st layer of protection and not adding to the cooling effect. Low ceiling will help retain body and appliance heat. Double layered insulation between floor slab and floor panels should keep the floor quite warm. Insulation has been added between the accoustic panels and the ceiling.

By reducing the room height, it will be easier to heat the room, with body heat and appliances etc.it will make the room more “cosy” and reduce the psychological ‘coldness’ of it.

2500mm

Without any Systems; and given a moderate outside temperature, the interior of the room will be slightly cold because of the altitude and wind passing by the window.

Lighting Program The lighting program is designed as follows: In the lobby and retail ceiling is separated at some distance and has averturas to let natural light and avoid making this area a very dark place, contrary to convert it into a brightly lit place for that type of material designated and design of the roof. The roof is ailiminado for all the vertices of a line of LED lights is the material with more life and provides as much light as light standards require.

The office has the same system, but let in light right through a dual wrapped facade with a double glass system provided that all windows that open with respect to the inclination of the sun and allow partial step natural light without annoying space.

Finally, the bar has a semi abrierto ceiling as he let all the natural light in the day and makes a very refreshing and bright atmosphere at night alone a fresh space is left and has also a system of ilumiacion LED This allows the entire roof lights and artificial light is distributed by a warm environment for users.

- Underfloor cooling is implemented throughout the whole building design. The Chiller cools the air and pumps it under the raised floor. The raised floor also acts as a thermal barrier between the exposed concrete slab and the floorboards. Insulation between the floorboards and the concrete also helps stop the thermal bridging.

- Warm air is returned through the ceiling void and is sent back down to the chiller to be re-chilled and circulated. In Winter; the air is boiled for underfloor heating and the cold air is sucked up through the vents.

Acoustic Program

- The solar panels help provide electricity to the lighting reducing the cost of lighting the building. Winter sunlight has also been maximised whilst reducing the amount of direct summer sun the floorplate is exposed to.

- Fixed desks are set back to avoid glare but mixed use spaces or open plan space is malleable for those wanting more light.

Within this building there are various structural and material strategies in place in order for the various programs to perform acoustically. As the buildings context is a street front busy commercial area the facade of the building is under a lot of stress from external environmental noise.

The increase of building height with the inclusion of the void allows for less noise transmission between the busy lower lobby and the performing office spaces above.

With various acoustical detailing the reverberation rate and SPL of the various programs is lowered to meet their goals accordingly.

At night the lighting is artificial, we have a system of LED lights that have the minimum requerimentos to illuminate the area, the LED system is one of the best sources of artificial lighting currently as it has lots of lux (LED Downlight CCT: 3000K) which is perfect for illuminating the quality of life is greater than an incandescent or fluorescent light and the amount of light that emerges is higher than any thus the cost is lower and the light is a saver system. This system is conseiderado be in the structure forming the main steel roof, as each vertex of the geometry is thought to insert a line of LED light, instead of using individual spotlights for space.

LED

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a pn-junction diode, which emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.

This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

According to the Australian Lighting Standards, the external corridor have the escencial light (40 - 160 lux) required ilumination for the waiting room, but in the day we need to use artificial light insted using just natural because the natural light do not penetrate completely this space Reference: AS/NZS 16801680.1 Part 1: General principles and recommendations

A revised downlight specification has been developed for this report, and is outlined in Table 5 (see right‐hand columns). It effectively updates the current DSF downlight specification to take into account the recent emergence of sophisticated test methods for LEDs and the introduction of MEPS for reflector CFLs. The table also lists the key requirements of other LED specification programs for comparison. Proof of certification by these other programs may reduce compliance costs, particularly where program requirements are at least as stringent as those required by IPART. Note that the IEA initiative does not currently include a certification aspect.

Downlight LED: Minium Efficacy: 42 lm / w Minium inicial flux: 345 lm (Recomended : 500 lm) Apperture: 16.5

LED Line CCT : 3000K

BENEFITS 1. Long Life Long life time stands out as the number one benefit of LED lights. LED bulbs and diodes have an outstanding operational life time expectation of up to 100.000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. If you leave on the LED fixture for 8h per day it would take around 20 years before you’d have to replace the LED bulb.

LED’s are different to standard lighting: They don’t really burn out and stop working like a standard light, moreover the lighting diodes emit lower output levels over a very long period of time and become less bright.

2. Energy Efficiency Todays most efficient way of illumination and lighting, with an estimated energy efficiency of 80%-90% when compared to traditional lighting and conventional light bulbs. This means that about 80% of the electrical energy is converted to light, while a ca. 20% is lost and converted into other forms of energy such as heat.

With traditional incandescent light bulbs who operate at 20% energy efficiency only, a 80% of the electricity is lost as heat. Imagine the following scenario: If you use traditional lighting and have an electricity bill of e.g US$ 100, then US$ 80 of that money has been used to heat the room, not to light it! Using LED illumination with 80% efficiency, the electricity costs would be around US$ 20 and you’d have saved around US$ 80.

The long operational life time acts as a multiplicator and helps achieve even more energy efficiency, especially large scale and when thinking in terms of urban infrastructure projects, such as cities, railroads and airports.

Think of e.g an airport using energy efficient LED lighting exclusively and achieving a 30% power consumption reduction in comparison with an airport using conventional lighting technology.

Because the long life span of LED lights, also the maintenance work - think of all the work and energy it would take to purchase, stock and change the conventional light bulbs of an airport you’ll see that you can make significant energy savings also when it comes to maintenance and replacement due to the long operational life times of LED lighting.

3. Ecologically Friendly LED lights are free of toxic chemicals. Most conventional fluorescent lighting bulbs contain a multitude of materials like e.g mercury that are dangerous for the environment.

LED lights contain no toxic materials and are 100% recyclable, and will help you to reduce your carbon footprint by up to a third. The long operational life time span mentioned above means also that one LED light bulb can save material and production of 25 incandescent light bulbs. A big step towards a greener future!

4. Durable Quality LEDs are extremely durable and built with sturdy components that are highly rugged and can withstand even the roughest conditions.

Because LED lights are resistant to shock, vibrations and external impacts, they make great outdoor lighting systems for rough conditions and exposure to weather, wind, rain or even external vandalism, traffic related public exposure and construction or manufacturing sites.

5. Zero UV Emissions LED illumination produces little infrared light and close to no UV emissions.

Because of this, LED lighting is highly suitable not only for goods and materials that are sensitive to heat due to the benefit of little radiated heat emission, but also for illumination of UV sensitive objects or materials such a in museums, art galleries, archeological sites etc.

6. Design Flexibility LEDs can be combined in any shape to produce highly efficient illumination. Individual LEDs can be dimmed, resulting in a dynamic control of light, color and distribution. Well-designed LED illumination systems can achieve fantastic lighting effects, not only for the eye but also for the mood and the mind: LED mood illumination is already being used in airplanes, classrooms and many more locations and we can expect to see a lot more LED mood illumination in our daily lives within the next few years.

7. Operational in Extremely Cold or Hot Temperatures LED are ideal for operation under cold and low outdoor temperature settings. For fluorescent lamps, low temperatures may affect operation and present a challenge, but LED illumination operates well also in cold settings, such as for outdoor winter settings, freezer rooms etc.

8. Light Dispersement LED is designed to focus its light and can be directed to a specific location without the use of an external reflector, achieving a higher application efficiency than conventional lighting.

Well-designed LED illumination systems are able to deliver light more efficiently to the desired location.

9. Instant Lighting & Frequent Switching LED lights brighten up immediately and when powered on, which has great advantages for infrastructure projects such as e.g traffic and signal lights.

Also, LED lights can switched off and on frequently and without affecting the LED’s lifetime or light emission. In contrast, traditional lighting may take several seconds to reach full brightness, and frequent on/off switching does drastically reduce operational life expectancy.

10. Low-Voltage A low-voltage power supply is sufficient for LED illumination. This makes it easy to use LED lighting also in outdoor settings, by connecting an external solar-energy source and is a big advantage when it comes to using LED technology in remote or rural areas.

If the SPL drops from 75dBA to 60dBA over 15 metres. Therefore to maximise the use of the open plan within the lobby, a masking speasker system can make this traffic noise unoticable.

If the masking speakers are producing a mask at 75dBA then the exterior traffic noise (which is the main acoustic concern of this design) will not be an issue.

RETAIL

secTIONS Acoustic Concept The retail and lobby areas have vastly different acoustic requirements than the other spaces also. These spaces focus on brining the outside in as through the lower circulation path cut through the building and also the overhead mezzanine levels dealing with retail. As these design decisions take priority over the idealistic low background sound level, realistic acoustic goals must be set. As the street façade is dealing with traffic noise set at 78dBA the internal SPL of the Lobby will be set at 50dBA as set by the ASN2107 recommended for a shopping Centre. Speech intelligibility is going to be an issue at certain points especially with the use of the open plan and mezzanine levels therefore suspended ceiling tiles are implemented to keep it relatively low <1.8, but still performing in the music frequency.

Rw + C = 28 (High Frequency) R.T. <1.8 This reverberation time will be achieved through the application of soft surfaces where possible. As there is a double height ceiling in play with the mezzanine level, ceiling tiles must suspended to absorb sound from the lower levels and prevent echoes. Acoustically treated glass which incorporates a PVB (polyvinylbutyral) in order to reduce sound transmission from the external street façade.

Acoustic absorption panels will be incorporated where possible on the internal lower level to decrease the reverberation time in spaces required such as specific lobby moments.

*Acoustic wall panelling - reduce reverberation

The Lobby and retail space is a very passive lower space of the building. The Lobby in particular is double height allowing for an excellent access route from and too both sides of Argyle street. The Lobby will feel open ended and transparent as it becomes very much a public space. It will need to perform as a balanced and ambient space in order to set the business tone of the internal environment. The lobby will have different acoustic requirements then that of the retail sections which exist on the mezzanine levels. The retail requires a much softer noise level as it requires greater speech intelligibility where it exists to the side of the lobby public space.

Within both these spaces there is a large opportunity for exterior street level sounds to become intrusive on the internal environment. Traffic is a major intrusive sound especially being so close to the source. The traffic noise will unfortunately be audible in this space as the passive ventilation and circulation takes priority, however steps are put in place to ensure this is as low as possible. In order to combat these intrusive sounds the lobby exterior is double glazed fixed frame glass in areas exposed to the most peak traffic noise, the interior is also fitted with suspended acoustically tiled ceiling to absorb as much internal sound as possible. The double height space of the lobby is also an issue for speech intelligibility therefore ceiling baffles are utilised and an internal masking speaker system set to mask the intrusive exterior traffic noise is set in place.

With the use of the double layered ceiling, the heat is allowed to escape through the top but also offers moments of shading from the harsh Summer Sun. Louvres in the building will shade low/glaring sunlight into the Lobby and Retail spaces. This is important as direct daylight can often be annoying in retail spaces.

The thermal insulation in this space is moderate due to the use of lightweight building materials and many windows. With the use of floor and wall insulation mixed with underfloor cooling and return through the ceiling void should keep the air quite temperate. However, due to the lack of thermal mass in this section and the many windows, there will be much thermal loss. This means that conditioned air will be essential but not always necessary; thanks to the operable windows and the thoroughfare void that will circulate and attract cool air in the summer.

Underfloor heating can be activated in the winter.

Winter The Lobby uses the Stack Effect as the Louvres and Windows are closed during the winter and the hot air rises, warming the interior and the cooler air gets returned to the boiler. Underfloor heating and return cooling is also implemented on both floors.

Summer The Lobby uses the Stack Effect to also cool the interior as the windows and louvres are now opened and allow fresh cool air to circulate and remove excess heat near the roof. This along with the underfloor cooling and return heat makes it an economical solution.

This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

According to the Australian Lighting Standards, the external corridor have the escencial light (40 - 160 lux) required ilumination for the waiting room, but in the day we need to use artificial light insted using just natural because the natural light do not penetrate completely this space Reference: AS/NZS 16801680.1 Part 1: General principles and recommendations

A revised downlight specification has been developed for this report, and is outlined in Table 5 (see right‐hand columns). It effectively updates the current DSF downlight specification to take into account the recent emergence of sophisticated test methods for LEDs and the introduction of MEPS for reflector CFLs. The table also lists the key requirements of other LED specification programs for comparison. Proof of certification by these other programs may reduce compliance costs, particularly where program requirements are at least as stringent as those required by IPART. Note that the IEA initiative does not currently include a certification aspect.

Downlight LED: Minium Efficacy: 42 lm / w Minium inicial flux: 345 lm (Recomended : 500 lm) Apperture: 16.5

LED Line CCT : 3000K

BENEFITS 1. Long Life Long life time stands out as the number one benefit of LED lights. LED bulbs and diodes have an outstanding operational life time expectation of up to 100.000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. If you leave on the LED fixture for 8h per day it would take around 20 years before you’d have to replace the LED bulb.

LED’s are different to standard lighting: They don’t really burn out and stop working like a standard light, moreover the lighting diodes emit lower output levels over a very long period of time and become less bright.

2. Energy Efficiency Todays most efficient way of illumination and lighting, with an estimated energy efficiency of 80%-90% when compared to traditional lighting and conventional light bulbs. This means that about 80% of the electrical energy is converted to light, while a ca. 20% is lost and converted into other forms of energy such as heat.

With traditional incandescent light bulbs who operate at 20% energy efficiency only, a 80% of the electricity is lost as heat. Imagine the following scenario: If you use traditional lighting and have an electricity bill of e.g US$ 100, then US$ 80 of that money has been used to heat the room, not to light it! Using LED illumination with 80% efficiency, the electricity costs would be around US$ 20 and you’d have saved around US$ 80.

The long operational life time acts as a multiplicator and helps achieve even more energy efficiency, especially large scale and when thinking in terms of urban infrastructure projects, such as cities, railroads and airports.

Think of e.g an airport using energy efficient LED lighting exclusively and achieving a 30% power consumption reduction in comparison with an airport using conventional lighting technology.

Because the long life span of LED lights, also the maintenance work - think of all the work and energy it would take to purchase, stock and change the conventional light bulbs of an airport you’ll see that you can make significant energy savings also when it comes to maintenance and replacement due to the long operational life times of LED lighting.

3. Ecologically Friendly LED lights are free of toxic chemicals. Most conventional fluorescent lighting bulbs contain a multitude of materials like e.g mercury that are dangerous for the environment.

LED lights contain no toxic materials and are 100% recyclable, and will help you to reduce your carbon footprint by up to a third. The long operational life time span mentioned above means also that one LED light bulb can save material and production of 25 incandescent light bulbs. A big step towards a greener future!

4. Durable Quality LEDs are extremely durable and built with sturdy components that are highly rugged and can withstand even the roughest conditions.

Because LED lights are resistant to shock, vibrations and external impacts, they make great outdoor lighting systems for rough conditions and exposure to weather, wind, rain or even external vandalism, traffic related public exposure and construction or manufacturing sites.

5. Zero UV Emissions

WALL WASHERS Wallwashing is a popular name for a lighting design technique for illumination of large surfaces.

It is mainly used with contemporary architecture; in public cultural buildings, museums and galleries; and in landscape lighting.

According to the Australian Lighting Standards, the offices have the escencial light (320 lux) required ilumination that is mean: moderate ilumination.

sections Acoustic Concept The office partition of the building with comprise of a low background sound level of ranging from 40dBA to 45dBA to some of the more breakout ‘social’ areas. This responds specifically to the AN2107 acoustic guidelines for office buildings. The meeting room requires a lower SPL of 35dBA and a lower range of R.T. with a focus more on speech intelligibility. This requires the façade to remove an approx. 40dBA of the intruding sound from the external environment for the meeting rooms which are situated on the voids within the tower.

Rw + C = 38 (High frequency) R.T. = < .8 In order to achieve this R.T. of less than .8 the finishes within the meeting room must be soft ie. Furniture with sound absorbing properties to be placed in the center, and the walls fixed with convex wall absorption panels in order to effectively spread, diffuse and absorb the sound.

The nature of this partition will feel very different to the open-aired bar and retail sections in that it provides a lower SPL for more efficient work with opportunities for communication through its open plan. There is however some sounds that have the potential to be intrusive and distracting to the employees inside. The main perpetrator is the street level traffic noise of Parramatta which will have to be made inaudible from inside the office. The main internal acoustic features employed in the design are the closed off and specific material nature of the meeting rooms. The Acoustic paneling on all interior walls and suspended ceiling tiles overhead office desks to absorb the sound and decrease any chance of echoes within the space. The glazed operable windows will decrease the background sound level within the office space. However for every three floors of the office building there will be a passively ventilated space which is completely service free, for this to perform there will be some noise from the street level however will be barely audible when louvers are closed.

BENEFITS 1. Long Life Long life time stands out as the number one benefit of LED lights. LED bulbs and diodes have an outstanding operational life time expectation of up to 100.000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. If you leave on the LED fixture for 8h per day it would take around 20 years before you’d have to replace the LED bulb.

LED’s are different to standard lighting: They don’t really burn out and stop working like a standard light, moreover the lighting diodes emit lower output levels over a very long period of time and become less bright.

2. Energy Efficiency Todays most efficient way of illumination and lighting, with an estimated energy efficiency of 80%-90% when compared to traditional lighting and conventional light bulbs. This means that about 80% of the electrical energy is converted to light, while a ca. 20% is lost and converted into other forms of energy such as heat.

With traditional incandescent light bulbs who operate at 20% energy efficiency only, a 80% of the electricity is lost as heat. Imagine the following scenario: If you use traditional lighting and have an electricity bill of e.g US$ 100, then US$ 80 of that money has been used to heat the room, not to light it! Using LED illumination with 80% efficiency, the electricity costs would be around US$ 20 and you’d have saved around US$ 80.

The long operational life time acts as a multiplicator and helps achieve even more energy efficiency, especially large scale and when thinking in terms of urban infrastructure projects, such as cities, railroads and airports.

Think of e.g an airport using energy efficient LED lighting exclusively and achieving a 30% power consumption reduction in comparison with an airport using conventional lighting technology.

Because the long life span of LED lights, also the maintenance work - think of all the work and energy it would take to purchase, stock and change the conventional light bulbs of an airport you’ll see that you can make significant energy savings also when it comes to maintenance and replacement due to the long operational life times of LED lighting.

3. Ecologically Friendly LED lights are free of toxic chemicals. Most conventional fluorescent lighting bulbs contain a multitude of materials like e.g mercury that are dangerous for the environment.

LED lights contain no toxic materials and are 100% recyclable, and will help you to reduce your carbon footprint by up to a third. The long operational life time span mentioned above means also that one LED light bulb can save material and production of 25 incandescent light bulbs. A big step towards a greener future!

4. Durable Quality LEDs are extremely durable and built with sturdy components that are highly rugged and can withstand even the roughest conditions.

Because LED lights are resistant to shock, vibrations and external impacts, they make great outdoor lighting systems for rough conditions and exposure to weather, wind, rain or even external vandalism, traffic related public exposure and construction or manufacturing sites.

5. Zero UV Emissions

WALL WASHERS Wallwashing is a popular name for a lighting design technique for illumination of large surfaces.

It is mainly used with contemporary architecture; in public cultural buildings, museums and galleries; and in landscape lighting.

According to the Australian Lighting Standards, the offices have the escencial light (320 lux) required ilumination that is mean: moderate ilumination.

Acoustic Concept The Bar and Gaming partition of the building will have slightly different properties. The Bar will need a low background sound level of 50dBA whereas the Gaming will need 45dBA. Both areas are focused on speech intelligibility however the Bar will need a lower range in order for close conversations to take place with a musical backdrop. The design decision to make the Bar an open aired environment will require the reduction of the SPL from 78dBA traffic noise from the lower level to 45dBA, therefore: Rw + C = 33 (High frequency) R.T. of the Bar <1.2 R.T. of the Gaming <1.5 This will firstly be achieved in the Bar space through the double height ceiling having suspended acoustic ceiling tiles for sound absorption. The use of soft surfaces to be employed as much as possible. The angled faรงade to deal with the exterior intrusive sounds.

Secondly the Gaming poker machine space will employ suspended ceiling tiles and limited windows to reduce glare and noise transmission. Acoustically sealed doors from the bar partition.

The Bar and Gaming are two separate spaces within the same floor level, and are performing very differently acoustically. The outdoor bar area is stimulating and a busy environment, it will have moments of intimacy and public circulation allowing for a business to run efficiently. The Gaming however is a much more controlled environment where the passive principles within areas of the bar, lobby or open office space will not apply and will have similar requirements to that of the meeting room space. This aspect of the building deals more with the control of the bar noise to the gaming with less focus on intruding environmental background sounds, merely because of the sheer height of the rooftop. Therefore there are sounds which cross from the bar space which are not wanted within the gaming area.

These of course are the SPL of people talking, Kitchen and central open bar area. In order for these sounds to not be intruding within the Gaming area the use of double corridor automatic doors is used in order to lessen the sound transfer between the two areas of the Gaming. In particular the Gaming â&#x20AC;&#x2DC;machineâ&#x20AC;&#x2122; area of which limited external light and sound is inherit with a very low reverberation range.

Double height Rooms allow for heat to escape from the ground floor and in a place where there are alot of people with alot of movement; the heat load would be very high.

Whilst there will be some nice afternoon daylight, the night sky and few artificial lights brighten/darken the space. The use of glass panels allow good transmission loss which is great in a bar.

Underfloor cooling and return air through the ceiling void is there incase conditioned air is required during hot summers.

concluSions reflections

Lighting Conclusion With this proposal we are designing a new system to boost natural lighting and not just use the artificial if you do not have a balance of both, so that the building is highly sustainable and wing functional time for different uses which was designed and each use has its own particular technique, lighting, improving the comfort level and creating a space suitable for such uses.

THERMAl CONCLUSION The newly reformed building has had the adequate changes made to the building to ensure that there would be the least amount of Thermal Load to the building. We’ve allowed for all natural strategies to play the primary role in keeping the internal spaces cool in the summer and warm in the winter. There is a secondary heating/cooling system in place for the whole building as a back-up but we believe through our comfort analysis that this will be only required for a maximum of 3 hours in a day. There are also break out spaces and mixed height levels that utilise a purely natural system and would be great for a building immersed in such a congested part of the city.

ACOUSTIC CONCLUSION Acoustically speaking the new Argle Street development generally responds to its immediate environment to lessen the noise transmission into the building. Situated within a busy commercial context, various programs surrounding the building impact upon the way various spaces feel within the building and how they are performing. This especially has an impact where the embedded passive design principles present themselves of which there has been some allowance for an increase in the background SPL of the interior. There is a constant balancing act to design these spaces which are performing both thermally and acoustically, of which material specification has had a large impact on the ‘polishing’ of the building and the differentiation of program within the entire structure.
