Prominent winds from the West & Northeast have unobstructed lanes onto the site, potential usage. Secondary winds from Northwest with partial bloackage from A&D
Heyward hall provides most shading during afternoon winter sun, not effective on site during rest of the year.
Runoff flows into A&D service path mostly from Search Hall. Must address how to manage rainfall and area most prone to flooding.
Search hall plays largest role in site shading Great shading from winter morning sun. Moderate shading from spring/fall morning sun. No shade during summer. A&D provides moderate shading from late afternoon summer sun.
Trees on site are generally aligned in a grid and can be grouped into microclimes. Removing trees near A&D will maintain shading near Search hall. Removing trees near Search will allow other trees to provide shading during most of the year.
Architecture School
The Abedian School influenced our orientation and prograommatic decisions
The north, east, and west facing walls and windows are less exposed due to the building’s orientation, and each of these openings is shielded and protected from the region’s intense and direct sunshine.
The studio areas on the greatest elevation to the west are shielded from the worst indirect summer sun by external vertical columns and an overhanging roof.
The façade and roof systems provide for the anticipated intensity and directional changes in the Queensland summer sun.
The information from the Site Analysis, sun exposure, and our Case Study informed our concept.
Sketch Southern exposure to sun maximized through form
The Heliodon experiments informed our form. Our sustainability goal is Net Zero through Solar Passive.
Not enough light in the spaces in the North due to lack of glazing
Roof tilted to allow more light into the deeper space
Part of the building casts a shadow on the other part
Skylights added Classroom placed in that area instead of the studio, because not as much light is needed.
Arbain,Less glazing on East facade, just for views and minimal light
Add overhangs for more shading

Heliodon Experiment 2
Utilizing a Grasshopper plugin called Honeybee, digital analysis of spaces could be studied. The program is used for basic energy calculations in terms of heating and cooling loads. Our team focused on analyzing the largest studio space in our design. The program factors in openings, solid walls, and sun shades to give a baseline result. The graph shows large heating loads in winter and large cooling loads in summer. Our team used this in relation with our sun studies to achieve sustainability goals that can mitigate such energy requirements.
The intent was to maximize sunlight exposure on the south facade. It faced the south at different instances in two separate planes. In the areas that received the most sunlight, curtain walls brought in light for warmth and maximized good views. In program, these spaces would be studios. Curtain walls on the east facade brought in more light, creating a pleasant experience. The other facades had no glazing because the curtain wall would bring in the necessary light and they lacked good views. The exception was the faculty space that extended northwest of the building.
OBSERVED
When tested in the heliodon, some design decisions worked and some needed adjusting. The design was blocking the summer sun and bringing in the winter sun. However, there wasn’t enough light in the northern areas of the building due to the lack of glazing on the other facades.
As a response, the roof was tilted to allow more light into the deeper space. Glazing wasn’t added in the northwest facade due to the closeness and adjacency to A&D. Glazing would promote a negative experience because of the minute amount of light it would provide and the disagreeable views. Skylights where added in the area of the building where light was needed and windows were added on the northeast facade where views were needed.
OBSERVED
The second model was tested in the heliodon. It allowed a significant amount of light into the majority of the spaces. However, there needed to be more control in the summer where less light was needed. In addition, the east facade curtain walls brought in unnecessary light that would overheat the space in the summer.
As a response, overhangs were extended over the southern facade to protect against the summer sun exposure. The east facade curtain walls became solid with some glazing for minimal light and views. The overhangs allowed the winter sun inside the building and protected the space from the summer sun.
