Our team chose the hot humid environment for our climate zone as we thought that it would be an interesting climate to do, something that we weren't familiar with and we also thought that it could generate many interesting and different designs.
Landscape:
As you can see from the pictures it's a really diverse landscaping from scrub like land to an abundance of vegetation.
Aspect of the brief analysed: -Climate -Energy efficient design
Climate:
In this region there are two types of seasons the dry and the rain seasons. During the dry season dry southerly and easterly trade winds are predominant. The humidity is relatively low. The rain season is characterized by warm temperatures but most of the rain is predominantly in the monsoonal troughs.
Energy efficient design:
Designing for a hot humid environment encounters very different challenges that we would encounter here, in-fact the complete opposite.
The humidity is high in a hot humid environment so air movement is crucial, to help perspiration to evaporate. The major factor in the environment is cooling of the house, the most energy efficient way to do this is passive cooling. It is least expensive means of cooling a home and has the lowest environmental impact. Passive cooling maximises the efficiency of the building envelope by minimising heat gain from external environment and facilitating heat loss to the following natural sources of cooling, air movement, cooling breezes, evaporation an dearth coupling.

Some design aspects that could be included to help with this include:
-Windows opposite each other to allow cross-ventilation
-Long narrow floor-plan in sleeping zone, to maximise through ventilation in bedrooms
-Open-plan living areas with high ceilings, to maximise air movement and reduce radiant heat to occupants
-Appropriate windows and glazing to minimise unwanted heat gains and maximise ventilation. -Elevate the house to increase exposure to cooling breezes
-Provide a large overhanging roof in all directions to minimize direct solar heat gain
-Orientation for exposure to cooling breezes

-Increase natural ventilation by reducing barriers to air paths through the building
-Large areas of louvered windows for ventilation
Ventilation diagrams
-Use light construction as the house will cool down quicker
-Use of light coloured roofs and walls to reflect more solar radiation and reduce heat gain.
-Use two layers of insulation to reflect radiant heat and prevent heat loads from reaching structure -Shading the walls especially the west and east

-Maximise north facing walls and glazing
-Minimize all west and east glazing and wall areas
Aspect of the brief analyzed: -off the grid
A self-sufficient stand alone system are more complex than a grid connected system and the main components include:
-a renewable energy source
-a control equipment for battery charging and back-up power source operation
-storage batteries
-an inverter
-a generator set-up for emergency back-up

Renewable electricity:
There are many different options available for renewable energy so our domus design can be off the grid.
1-Photovoltaic panels
Convert sunlight into electricity, little maintenance and no moving parts. There are both solar cell systems and solar module systems.
2-Wind generator
Domestic wind generators are usually stand alone power systems and designed to charge a battery bank
3-Micro Hydro Generators
Convey the mechanical energy of flowing water into electrical energy
Water re-use and minimizing water use:
There are many different systems available are here are just a few options on how to re-use and minimize water for the domus design
Black water:
Can be treated then used on the garden areas, but a good treatment system is ideal
Grey water:
Needs to be filtered through a system before being treated also in another system, than can be stored for later use in the house or for outdoor use.
Waterless toilets:
There are two types of waterless toilets a continuous composting toilet and batch composting toilets.
1-Composting toilet:
Consist of a single container in which excrement is deposited, and decomposes as it moves slowly through the container. It is then removed as compost from the end product chamber.

2-Batch composting toilet:
Batch CT's consist of two or more containers that are alternated so that the 'active' container is being used while the pile in the 'fallow' container has time to compost without the addition of fresh excrement and the potential for re-contamination.
As you can see from the pictures it's a really diverse landscaping from scrub like land to an abundance of vegetation.
