Week 11, Fiday 18th May, 2007
Detailed design and representation of domus

This week I drew up the final floor plan for our domus idea on cad as well as the beginning of the elevations on cad for the final. As shown a few things need to be changed and added. The items that need to be changed include vegetation, services, stairs and balustrade. One major thing that need to be changed are the line weights, need to work out what information is the most important and what to reduce down in pen thickness for the least relevant information.

We're still keeping the main principles that we developed including:
-lightweight construction, for cooling purposes
-louvers at the top of the walls for cross ventilation
-large expanses of bi-fold doors for cooling purposes and also to bring the outdoors in
-windows opposite one another for cross ventilation
-movable timber screens for cooling purposes
-'pod' design or zoning of areas for cooling purposes, also to distinguish private and communal space
-grouping of services together so minimal plumbing etc.
-elevated for ventilation
-large eaves for shading purposes

Basically our design is about being as comfortable in the space as possible, keeping the house at a comfortable temperature and numerous different ways to achieve this.














During this week we researched for more in-depth information into the services for our domus idea as it is an essential part of the whole concept to be 'off the grid.' So the following are our final for services for the domus idea.

Services for our domus idea:

-Power:
Solar panels with adjustable frames for optimum solar gain.
-Water:

*Rainwater tanks:
Storage tanks supplied for firstly roof water catchment tank under the house, second a tank for grey treated water that is in the open and the third tank will be for hot water use such as shower and kitchen which is again located outside for heating purposes.

*Black water:
The toilet water supply will be grey water supplied, and the system will be a septic tank and treatment tank, for water re-use on the garden areas.

*Grey water:
A treatment system again for the water from the laundry, bathroom, and kitchen which can be re-used in the house. A storage tank for the treated grey water will be supplied.

-Waste:
Chooks and worm farm for food scraps.

-Windows:
Double-glazed windows with a high performance external tint, a low e-coating and timber frame will be used as it can reduce cooling energy requirements by almost 70%.
