Cost Analysis
Initial Cost: The initial cost evaluates how much must be input at the beginning of the project. The expected life span of emergency shelter is shorter than conventional building, thence the initial cost is concerned.
Operation Efficiency(Cost): This criteria evaluates the overall operating cost of the system as well as the efficiency of the system that associated with the building size.
Maintenance Cost: Since emergency shelters are usually not designed for years long duration, the maintenance cost is less concerned.

Maintenance Cost: Since emergency shelters are usually not designed for years long duration, the maintenance cost is less concerned.
construction
Contractor Familiarity: Since emergency shelters typically require short construction duration, contractor familiarity is vital.
Ease of Assembly(Time/Labor): In some situation, emergency shelters needs to be constructed by less trained labors. So ease of assembly is important.
Safety: Safety is the primary consideration. This criteria includes the safety during construction as well as during operation.
Weight/Size: This criteria evaluates the weight and size of equipment. For emergency shelter, light-weighted equipment is more favorable.

heating and cooling
Temperature Heating: Heating is the fundamental function of HVAC system. This criteria evaluate the effectiveness of the system in terms of generating and distributing heat.
Temperature Cooling: Cooling is the fundamental function of HVAC system. This criteria evaluate the effectiveness of the system in terms of generating and distributing cooled air.
Temperature Cooling: Cooling is the fundamental function of HVAC system. This criteria evaluate the effectiveness of the system in terms of generating and distributing cooled air.
functionalities
Particulate: Some systems such as VAV can control the particulate level of room temperature. This criteria is important since it associated with health of users.
Pressure: Some systems such as fan can alter pressure of the indoor air. This criteria is included but not very concerned during evaluation.
Noise: Noise control is an additional function of several systems. This criteria is included but not very concerned during evaluation.
Aesthetics: Aesthetics value is the secondary attribution of HVAC system. This is the least concerned criteria during evaluation.
Energy Footprint: This criteria evaluates the energy cost of system manufacture. This criteria is included but not very concerned during evaluation.
Relative Humidity: Several systems could alter the relative humidity inside the room. This is an important criteria during evaluation.
Life Span: Emergency shelter has expected life that usually shorter than conventional building. This is an important criteria during evaluation.
