Requirements for air-conditioning :
> Feels of comfort (environmental climate, activities in limited space)
> Workers productivity & industry production (need comfortable environment)
> Health concern (environment pollution)
> Tools (electronic apparatus & computers)

# data[].attributes.body
• Building orientation

- Prevent any surface from facing the West-East sun to reduce

penetration of heat.

• Building enclosure

- Thick layering and good building material can control heat to

penetrate into building excessively

• Fenestration

- Prevent any openings that could lessen the air cooling effect.

• Surrounding environment & climate

- Prevent reflected sunlight from other buildings ( e.g. from glass,

building materials, etc.) that could add heat into your building

• Activities and equipment

- Human and equipment releases heat there might need high extra cooling capacity to taper the heat in building.
