The Design of Kitimas Building for Saving Energy and Environment

The Plan and Landscape Architecture
1. Conserving big trees in the construction site
2. Conserving topsoil
3. Planting trees for shade: the right trees in the right place
4. Placing at least one big tree/ 100 m2 in open area
5. Shading the solid-surface floor by using trees and/or buildings
6. Planting right trees match with the climate

Building Envelope
1. Protecting roof for the heat
2. Protecting walls and windows from the heat
3. Air leakage through windows and doors must be less than 0.6 l/s-m of crack

Air conditioning system
1. Minimum energy efficiency standard for air-conditioners, 10% more than the requirement of the law
2. Installing water pump
3. Installing cooling tower
4. Installing air handling unit
5. Using refrigerant that has less impact on green house effect
6. Wind ventilation; using the wind for passive cooling and fresh air through the building
7. Dividing the building into thermal zone
8. Separating the areas between air conditioning and non-air conditioning areas

Lighting System
1. Meet the standard of the luminous intensity at the minimum
2. The standard of maximum lumen per square meter
3. Providing control lighting system for energy saving
4. Separating the circuit zone of lights for energy saving

Renewable Energy and Energy Management
1. Using natural light instead of artificial light
1.1 Using artificial light system
1.2 Using natural light at the main areas
1.3 Using daylight more than 20% at the minor areas

2. Energy Management
2.1 Separating branch power meter for measuring air conditioning areas and lighting

Sanitation System
1. Water saving sanitary ware
2. Water saving faucets/ sensor faucets
3. Water pump with high efficiency motor
4. Separating water meter in the main building and cooling tower
5. Rain water harvesting
6. Wastewater treatment and grease trap tank
7. Wastewater reuse

Materials and Constructions
1. An operation plan for protecting pollution and noise from construction
2. Choosing paints that reduce environmental impact
3. Garbage separating and recycle
4. Using renewable materials to reduce waste
5. Using insulation than has less impact on environment
6. Controlling indoor chemical and pollutant source

Other design techniques and energy and environment saving strategies
1. Design natural ventilation for the underground parking lots
