oppenheim testing

To test our design for appropriate shading needed for our site, we decided the Oppenheim Assessment Method, along with Shading Diagrams etc., would give us a good indication of whether or not our window sizes were too big for the amount of shading provided. To do this test we have made all our shutter windows in glass and the adjacent floor space into thermal mass flooring. (please note pages are back to front so when viewing go from the bottom up!)

water analysis

For the Djilimbardi site it is essential that we provide excellent water catchment systems and reserve water systems as well. Seeing as the site only receives rain for 3-4 months of the year during monsoon season, this rain needs to be captured and stored for about 8 months of the year. We have included 3 Freshwater tanks and 1 Greywater tank, which can work by themselves or if necessary in conjunction with the bore water system that is available on the site.

minima

This was my minima. My aim for this project was to provide privacy as well as enough sunlight to be able to use the interior rammed earth wall as thermal mass.

By assessing the sun angles and adjusting the eaves i was able to effectively achieve a balance between shading during summer and warming sunlight during winter.

The site in which my minima was to be located was in between the palm trees overlooking the bay.

MINIMA PROJECT

I consider much about temprature, so i designed second floor for people to use when it comes to summer, it also can be lifted when people sleep on the second floor. There is another bed hide in the ground floor, people can revolve it when not use , and the bed will become the same flat with wall.The second floor is totally open, just use bamboo curtain to cover which is good for ventilation.

MOSMAN 2 refining

One of the problems of our design has been dealing with the junctions of the modules.
Because they lock in at different angles the spaces can be awkward.
We resolved them well for our main presentation, but still had a few issues with the level changes and fitting stairs neatly into the plan and sections.


We therefore needed to map our main circulation route through the site, which of course is the shortest route. We also wanted to ensure there was still a covered accessway for those rainy days.
Above is an idea for primary and secondary stair locations. The stair between the bedrooms and the bathroom does cut into the building a lot more, but we could shift the Studio module out a little (along with the Living module). However, as this is not the primary access, maybe it's okay like this?

Another element of our Refining process is to develop the internal spaces further. We have decided to develop the Bedroom modules, the Washroom, Studio and Kitchen spaces.

For the Bedroom modules we a looking at enhancing the 'cave-like' space. Initially we sketched up a convex shaped ceiling in the rooms, but this caused problems with head-heights and glazing lines. Perhaps this concave shape would better suit. It will enable the window and wardrobe to keep the same line, whilst still creating the 'floating' affect with a glass infill above.

This is a rough sketch of a typical Bedroom module. The design has been developed to included a vaulted ceiling. The single, large wardrobe door slides across a rail to open the robe fully. The wardrobe finishes at the same height as the window and a glass in fill panel sits above to provide sound insulation, and gives the impression of a floating roof.

HEAT GAINS


We completed the cooling calculations for each Module of the Domus Djilimbardi design using the ASHRAE method. This method will give us a basic understanding of the heat gains occurring during the hottest periods in summer.

As expected, and designed, the sleeping quarters perform the best, staying relatively cooler than the other areas.

The Living Quarters are exposed to the greatest heat gains, which is why we designed the dam underneath and included the most openable louvred walls, for increased ventilation and evaporative cooling.

SUN SHADING

The diagram below shows the summer sun angle penetrating the shade screen designed to block the sun from entering the Living Quarters. In order to prevent the sun from getting trough the screen will need to be re-designed.

The screen can be widened to block the sun's angle, or the spacings between the slats reduced.

FLUID MAPPING

Ventilation is our main cooling system for Domus. We therefore decided to test our design using fluid mapping, enabling us to see how the mound and courtyard affect the wind through the site. We had concerns that the mound may deflect the winds, reducing ventilation, and that turbulent swells may occur within the courtyard, thus making it uncomfortable to be in the space. Below are a fluid mapping snapshots, in plan and section

The fluid mapping test showed us that our design works really well with the main prevailing winds. The mound and the layout of the building on the site assist in the ventilation strategies of our design.

We observed some swelling occurring in front of the Living Module with the cooler westerly winds. This suggests the wind is being blocked and is creating an uncomfortable space.



However, when we mapped the flow through the section we can see the winds pass quite easily under the floor and over the dam.

The above test (south0open) mapping the wind over the mound, shows the angle of the mound and position of the sleeping quarters is perfect for directing winds into the Living Quarters
The only area of concern is the swelling that occurs outside the Sleeping Quarters. This is due to the deep verandah eaves incorporated into our design for weather protection

Mosman 3 Group progression!

At first we chose to elevate our domus house because of its location......near a flood plain.....but chose againt this after considering some of the existing houses in the area (none of them are elevated)

Design relies on passive cooling techniques such as cross ventilation and evaporative cooling (grey water ponds with a fountain)......however our final design does not have the ponds, grey water turns septic after a certain time period......not very pleasant!


Our design then progressed to being underground....some parts lowere than others.....separating private sleeping areas and common courtyard!

effective shading on all sides of the house is provided by a shade sail......tent like in structure!
