Design Proposal

Final idea

1. Cafe - Container Sidewalk Coffee House

• Objectives: To prevent pollution and green the environment

• Character: Use passive solar system + Green the environment

• Principle: Between architecture and landscape

2. Experience area - Indoor waves pool

• Reason: In Malaysia, the most influential impact of climate change is the floods

• Objectives: To let people feel the floods experience

Energy Efficiency

World Availability of Direct Solar Energy

Advantages of reducing energy waste:

• Quick and clean

• Usually the cheapest to provide more energy

• Reduce pollution and degradation

• Slow global warming

• Increase economic and national security

Widely used devices that waste energy:

• Incandescent light bulb

• Motor vehicle with internal combustion engine

• Nuclear power plant

• Coal-fired power plant

Solar Heating System

Passive solar design basic element/principle

• Aperture/Collector: The large glass area through which sunlight enters the building. The aperture(s) should face within 30 degrees of true south and should not be shaded by other buildings or trees from 9a.m. to 3p.m. daily during the heating season.

• Absorber: The hard, darkened surface of the storage element. The surface, which could be a masonry wall, floor, or water container, sits in the direct path of sunlight. Sunlight hitting the surface is absorbed as heat.

• Thermal mass: Materials that retain or store the heat produced by sunlight. While the absorber is an exposed surface, the thermal mass is the material below and behind this surface.

• Distribution: Method by which solar heat circulates from the collection and storage points to different areas of the house. A strictly passive design will use the three natural heat transfer modes- conduction, convection and radiation- exclusively. In some applications, fans, ducts and blowers may be used to distribute the heat through the house.

• Control: Roof overhangs can be used to shade the aperture area during summer months. Other elements that control under and/or overheating include electronic sensing devices, such as a differential thermostat that signals a fan to turn on; operable vents and dampers that allow or restrict heat flow; low-emissivity blinds; and awnings.
