SUMMER SOLSTICE

Summer Solstice - 9am

During the summer solstice, the solar path is at its highest elevation angle and covers the greatest range of azimuth, meaning there will be the most sunlight exposure for the year during this period.

Summer Solstice - 1pm

The relatively high angle also reduces the amount of direct sunlight that penetrates throughout each floor, but increasing the amount of reflected glare and diffused light within these spaces which could affect thermal comfort. There are also reduced shadows cast within exterior areas around the building, which may encourage activity around the building..

Summer Solstice - 5pm

1.1 orientation

EQUINOX

Equinox - 9am

During the equinox, the solar path is at its mean elevation angle. During these months the angle of elevation may introduce both direct sunlight and glare within these spaces which may cause differences in comfort. The shadows cast are not as dense or persistent as those during the winter, while still providing buffering shade from the sun during the transition from summer to winter and vice versa.

Equinox - 1pm

Equinox - 5pm

WINTER SOLSTICE

Winter Solstice - 9am During the winter solstice, the solar path peaks at a much lower altitude and lower range of azimuth, therefore there is a lower amount of sunlight cast upon H-Building during the winter months. As well as this, there are longer and more persistent shadows throughout the site during this time.

Winter Solstice - 1pm

Winter Solstice - 5pm

The lower angle allows for greater penetration of direct sunlight at this angle into H-Building, which helps provide greater thermal comfort as compensation the reduced temperatures.

BUTTERFLY DIAGRAM

From this butterfly shadow diagram, it is evident the most dense areas of shadow are along the southern facade of H-Building, and it also cast the longest shadows onto Dandenong Road adjacent to it. This is self-evident considering it is the tallest building on site.

Shading Diagram (25th June 2016 15:00)

The stereographic diagram indicates that at the specified point of analysis at the base of the building, the H-Building will provide sun protection and block the sun between sunrise and 3pm during the summer solstice. Furthermore, during the winter solstice and equinox, there is almost no direct sun exposure to the given point on the Southern entrance of the building. What we can derive from this is that H-Building provides excellent sun protection along the Southern facade for shaded activities, as well as for ambient worksapces.

When analysing the annual Prevailing Winds diagram (right), the largest proportion of wind was coming from between 15-30 degrees NorthEast, at an average speed of 10-15 km/h. The overall majority of wind approaching the site is from a Northerly direction, therefore it would appear that H-Building provides a great deal of wind protection from that direction for the central courtyard of the university. However, there is still exposure to the highest speed winds that largely come from an Easterly direction directly through the centre of the campus.

The average daily solar insolation diagram (top left) indicates that the North and West facades of Building H take the highest volume of heat load and insolation than any other facade of the Monash Caulfield Campus on a given day. Average Daily Solar Insolation (Equinox) 1144 kWh/m2

640 kWh/m2

The cumulative yearly insolation diagram (below left) further illustrates that throughout the year, the West facade receives over 1100 kWh/m2 of insolation energy at its highest point. Whereas the adjacent car park to the West offers shading during the afternoon to the lowest points of the facde. This suggests there would be a signnificant amount of heat load placed on the highest points of the West facade, particularly in the afternoon and sunset. This would affect the comfort of the activities taking place on each level due to the significant glare from the afternoon sun.

The daylight factor along the edges of the exterior walkway around Building H at Ground Floor Level are in excess of desirable levels of light and heat load, reaching in excess of 15%. However the enclosing glazing of the internal space offers more comfortable workspaces between the glazing and internal partition walls at 2-5%. Furthermore within the partition walls, there is further reduction in daylight levels below desirable office working area levels of 400-500 Lux, which would necessitate use of artificial lighting and excess energy. Sectionally, there is a slight imbalance in exposure to natural light along the Northern facade (Long Section) as opposed to the Western and South facades (Short Section) and only penetrating approximately 5m into the space at an adequate working level.

However, as the ground level is inset below an overhang of approximately 2.5-3m, any analysis of the windows on the ground floor would be redundant, therefore a hypothetical analysis of the solar exposure at ground level and the changes in conditions relating to the edging of the windows is still an important point of analysis. There is the largest portion of direct radiation to the North facade of Building H, suggesting greater heat gain, with more light filled spaces.

Hypothetical Location of Windows

Before undertaking analysis of radiation ofthe ground floor of Buildng H, it must be qualified that the window openings analysed on the north-east corner of the building do not exist on the building currently, as it is a service core.

The largest proportion of diffuse radiation is in fact along the Southern facade of Building H, more suitable for ambient lighting in work and study spaces.

The vertical planes along the sides of the window appeared to provide the greatest percentage of shade from direct sunlight during its most prevalent periods of the day, throughout the year. Assuming 12% efficiency, there could be as much as 10 kWh/m2 of energy generated from this isolated section of the facade during December and as little as 800 Wh/m2 during the month of June. There is a larger proportion of received heat during the summer months, as outlined in the â&#x20AC;&#x2DC;Total Monthlyâ&#x20AC;&#x2122; graphs below.

Although there is typically larger amounts of natural sunlight during the Summer months, the Equinox and winter solstices offer a lower angle of elevation, allowing the sun to shine more directly onto the lower levels of the North facade, which is a possible explanation for the larger spread of total radiation through the winter months.

Conversely, for the remainder of the year, there is not suitable levels of radiant temperature to ensure an adequate level of spatial comfort, without the intervention of artifical heating. The Southern half of the ground floor plate is clearly too cold throughout the entire year, therefore requires continuous and large amounts of energy to maintain a comfortable temperature within the space.

The accuracy of the Ecotect analysis of the percentage dissastisfcation for the following diagrams is called into question. This is because the majortiy of the calculations returned a value of 100% dissatisfaction, perhaps due to lack of accuracy in inter-zonal adjacency calcculations. This being said, these results highlight a series of crucial issues to be faced in the ground floor of building H. Lack of natural ventialtion, direct sunlight, thermal mass and other factors that improve thermal comfort necessitates use of artifical environmental control systems to provide adequate comfort at these lower floors. This then results in higher energy consumption and reliance on automated systems, and may require introduction of systems and technologies that can be more efficient and sustainable.

1.4 thermal comfort

hourly temperatures

The hourly temperatures during the hottest day of the year would result in uncomfortably hot temperatures within the ground floor, however there was increased wind speed which could alleviate this thermal gain with natural ventilation through the spaces. Furthermore on the coldest day of the year, the temperature became uncomfortably cold because of the lack of thermal mass and ability to retain the solar energy received throughout the day.

1.4 thermal comfort

heat gain / loss

Equinox

The largest amounts of HVAC load and conduction occurs on the hottest day of the year, but this is not correlated to direct sunlight (due to increased angle of elevation of the sun). During the coldest day of the year, there is the lowest hourly gain of energy perhaps due to increased cloud forms or less direct sunlight throughout the day.

Coldest

Hottest

1.4 thermal comfort

monthly loads / discomfort

The ground floor of Building H becomes too hot more quickly without mechanical systems during the months of January through to March, due to increased heat load. It is also the most uncomfortably cold during the month of July, through the quickest loss of heat. This perhaps due to the excess of glazing that allows large amounts of heat load to penetrate the spaces, but also be released quickly during the winter period.

1.4 thermal comfort

fabric gains

The use of double glazing and 100mm insulation asisted in increasing the heat and fabric gains from solar radiation within the spaces.

Single Glazing

Double Glazing & Insulation

The use of greater thermal mass allows the heat gain to slowly radiate into the adjacent spaces and conversely allows for the internal temperature to decrease at a much slower rate than single glazing, ensuring more consistent and comfortable control of internal temperature for occupants.

Percentage Dissatisfaction Regardless of the time of year shown in each of the diagrams centreright, the percentage of patrons who would be dissatisfied with the thermal comfort of the ground floor space is not acceptable without reliance on mechanical systems.

Due to lack of thermal mass and excessive glazing, the diagrams below right suggest there is rapid heat gain/loss to either extreme throughout the year. This makes it difficult to maintain a constant temperature within the floor spaces and a comfortable study/working environment.

DOUBLE SKIN FACADE

“The occupancy of a building of this type is determined by the student calendar and this offers only relatively small windows of opportunity in the post-construction tuning period for identifying system performance levels and making adjustments.”

Double skin facade of custom aluminium zinc-coated perforated louvres and inner glazing is used on East, North and West facades to manage heat load and provide stunning aesthetics. Close-Up Detail of Aluminium Louvres

South-West Facade junction

Pros: - Relief from heat load and solar glare - Cross ventilation - Double skin generates interstital space for activation and insertion of program - Louvre panels provide different functions in different situations i.e. space divider vs solar screen

“Due to the different building occupation rates throughout the calendar year, the usual quarterly review, assessment and discussion around performance has been altered such that the number of meetings increase during peak occupation times so as to quickly identify and rectify performance issues.”

Cons: - Fixed positioning - Relative embodied energy of materials

The designers and faculty admitted that the volume of students that began to use the space was significantly higher than initially anticipated due to other faculties beginning to use the space. Resulting in further tweaks to the systems.

RAAD STUDIO

O2A STUDIO

The Lowline proposal aims to renovate an existing underground rail system to become a thriving park of plants and culture within New York City, as a response to loss of green space and land.

“Part of an invited competition, the design brief required a two-phase proposal sited at the focal point of the Tel Aviv University Campus: an initial 3,500 square metres of classrooms, offices and an auditorium and a future 1,500 square metres of extra classes and offices.”

It involves custom designed solar dishes that concentrate natural light and transfer it below ground at a frequency conducive to photosynthesis to allow plants and greenery to flourish below ground. To prove their theory, RAAD Studio built a prototype of their system to grow plants within an old warehouse under similar conditions - which was successful. This system could be translated and altered to suit the context of Building H, particulary at ground and basement levels.

“Though not selected for the final design of the school, the o2a Studio proposal for the Lorry I. Lokey School of Management encompasses contextual, programmatic and climatic concerns in an elegant solution.” “The design of the building relies on its internal atrium. Along with acting as a solar chimney to cool the building interior, the atrium contains the building’s vertical circulation, creating a social spine from which the narrative of the project arise.” http://www.archdaily.com/773363/o2asproposed-tel-aviv-university-buildingcontrols-natural-light-and-wind-for-asustainable-solution

The Proposed Tel Aviv University strategically opens up the ground floor and separates the core from the building to create natural ventilation throughout the building.

Level 2

The program of the building was strategically designed around the needs of the University, balanced against the external influences affecting the building. This in effect creates a building which has great occupant usability and comfort.

The external rooms are then deliberately staggered as to allow this natural air flow to be captured and projected through the spaces.

“To avoid direct sunlight in the classrooms, the north façade of the building was rotated to be 45° to the main university plaza. “

Pros: - Relief from heat load and solar glare -Natural Ventilation - Generates greater air quaility -Windows which face inwards to the core allow for user participation

Measuring 92 meters tall, the Groningen tower is outfitted with soft, undulating curves as a way to replace the traditional stoic and commanding presence of institutional buildings with a more “friendly and more future-orientated” approach. In addition to creating a new personality for the exterior, the façade also integrates shading, wind control, and daylight penetration with its finshaped elements. These horizontal fins keep a large amount of the heat outside the building, reducing the requirement for cooling. http://www.archdaily.com/130671/ eea-tax-office-unstudio

Design Intervention: Ecotect Analysis ATRIUM SECTION LIGHTING LEVELS The Ecotect diagram at right clearly demonstrates that by penetrating the floor plate to create an atrium space around the central circulation, there is a significant improvement in daylight levels throughout each floor plate, particularly at ground level which was severely lacking. So too the skewing of floor plates to the west provides added light to the eastern facade in the morning and a greater shading to the glare and heat load of the western facade due to overhang of each floor plate.

GROUND FLOORPLATE NATURAL LIGHTING

While the atrium provides larger daylight levels towards the centre of each floor plate, the double skin facade is also shown to assist in shielding the northern facade from harsh light and heat load.

By opening up the ground floor level as a public space, it is clear that there are greater levels of daylight even at the lowest of spaces within Building H, making it a much more pleasurable space to inhabit.

Furthermore, our interventions have evened the distribution of light across the floor plate that was initially in excess to either extreme, due to the double skin louvres on the exterior, and atrium within the interior.

We have also negotiated the increased wind load with planter boxes as a buffer to prevailing winds and noise from Dandenong Road.

The fourth floor plan represents the overall reorganisation we have applied to teaching and research spaces within Building H. To the North facade there are offices and classrooms showered with light (controlled by louvres). The dividing walls are recycled concrete from the aggregate produced via demolition of floor plates for the atrium. Frosted glass creates a consistent connection across these spaces. The North East corner houses shared social and study spaces with increased light and views to the north. The East wing incorporates meeting spaces, while the South wing maintains the original facade to allow ambient lighting for office and private study spaces. The West wing is entirely open plan office spaces, removing the original divided and isolated office spaces in order to foster a more positive and pleasurable work space showered with light and breathability. A reduced size service core has also been moved to this area.

The roof garden space along the West wing is a tranquil place of enjoyment for staff and students to gather. The garden beds and roof drainage also filter rain water into a grey water recycling system used for toilets and irrigation for plants, reducing supply costs. The louvre screening system also continues around this level as a buffer from wind and harsh western glare. The remainder of space is open plan social and study spaces with plentiful lighting for a positive atmosphere.

The section at left demonstrates how the offsetting of floor plates similar to the Tel Aviv University precedent harness the prevailing winds to encourage natural stack ventilation to move up the atrium.

The offset is dramatic along the northern side of Building H because we believe there will be greater requirement for ventilation due to heat load on the facade, whereas the southern facade requires more subtle control over temperature.

HEAT

The glass louvre roof allows both light and ventilation to cycle through the atrium space.

Lecture Theatre Space

The diagram at left demonstrates how the natural stack ventilation from the atrium spaces are filtered through openable windows within each room at floor height. As it heats up it is removed from the space through a ceiling height window into a gap between the room and outer facade for improved ventilation. Temperature can be further controlled through use of chilled coils attached to the roof to force cool air downwards. This is cooled by a phase change material filter to reduce reliance on inefficient cooling systems. Conversely, heated coils hidden under screed radiate heat upwards through the space, heated by an anaerobic digester feeding a gas boiler.

KINETIC FACADE

The louvres are composed of frosted glass attached to steel pipes. Pipes are then connected to a gear rotation system in conjunction with other louvres proportional to each room. They can then be rotated via a control panel within each room. This adds a greater level of perceived comfort within each space due to the occupantâ&#x20AC;&#x2122;s ability to control the lighting and temperature conditions of each space.
