1. GES SYSTEM THE IMPORTANCE OF GES SYSTEM IN BUILDING
Modern building –shelters from rain, wind snow, sun and other harsh conditions of nature.
Built to create better, more consistent, more productive environments in which to work and to live.
Features needed-lighting; comfortable space temperature, humidity, and air quality; convenient power and communication capability; high quality sanitation; reliable systems for the protection of life and property.
e.g:
i. block-type buildings without windows (such as department stores), totally dependent on electrical lighting, ventilation, and space conditioning.
ii. High rise building rely on high-speed vertical transportation and high pressure water for drinking and cleaning purposes and for protection against fire.

2. GES SYSTEM SYSTEM The Scope of building GES
Consists of various complex systems
Varies according to; living standards of the society, climatic conditions,
occupancy & quality of the building, etc
Example;
House in a mild climate does not need heating or cooling,
bulk storage does not need heating in winter, hospital need a supply of medical gas,
Office building need simple cooling device VS high-rise building needs central
cooling systems.

3. GES SYSTEM Building GES Systems Classification Mechanical Systems
HVAC; (Heating, Ventilating and Air Conditioning)
Site utilities; (Water supply, storm water drainage, sanitary disposal, gas supply)
Plumbing; (Water distribution, water treatment, sanitary facilities)
Fire protection; (Water supply, stand pipe, fire and smoke detection, automatic sprinklers,
annunciation)
Special systems
Electrical Systems
Electrical power; (Normal, standby, emergency power supply and distribution)
Lighting; (Interior, exterior, emergency lighting)
Auxiliary or support system; (Telephone, signal, data, audio video, fire alarm, security systems)
Building Operation Systems
Transportation; (Elevators, escalators, walkways)
Processing; (Production, food service)
Automation; (Environmental controls, managements,)

4. GES SYSTEM Impact of Building M&E Systems Space planning
Architectural Design
Construction Cost
High-rise Building Design
Global Environments
Impact on Space Planning
The GES affects; the gross floor area, footprint (size & shape
of ground floor), floor to floor height, geometry, architectural
expression
Allocations are made during the space programming phase to
allow appropriate size and strategic location
The most challenging and the least developed procedures in
the architectural design process
Example; Large office buildings: Central cooling/heating equipment needs extra floor to floor height (22ft~), Commercial Building: Complex ductwork, HVAC and plumbing needs ceiling cavity (2~3 ft)

5. GES SYSTEM Impact on Space Planning
Although the ranges are broad, they serve a basis for conceptual
planning and budgetary
Central vs Independent Systems, Ceiling vs Exposed piping/
ductwork, Passive vs Active Systems
* Buildings other than those used for classrooms follow the space required for specialty buildings such as laboratories, computer centers and residences.

6. GES SYSTEM SYSTEM Impact on Architectural Design
Early building design; one room, one window for ventilation and lighting
Modern buildings develops according to the modernization of building M&E systems
(common building geometry figures)
Building Height vs Space utilization; 7 storey (75ft ~) buildings are considered high-rise
determined by the reach of firefighters ladder, limit the ability for human to walk up and
down stairs, transportation is needed
Height increases = Less usable space on the floor – more floor for stairs, elevators,
structural elements, M/E shafts, etc

7. GES SYSTEM Impact on Construction Cost
Building Height on Construction Cost
Taller buildings needs more time, hoisting equipment and complicated scheduling to raise
M/E materials to upper floors
Buildings more than 10 stories increases 5-15% of cost for the next 5 stories per floor area,
15~ stories increases 10~15%
GES Systems on Construction Cost
Depends on; the type of building, standard of living, architectural design, the systems selected
Impact on Operating Cost
Includes; energy consumption, routine maintenance,
repairs, replacements and utilities
Building Structural components (except roof) are usually
long lasting
GES vs initial capital investment

* Buildings other than those used for classrooms follow the space required for specialty buildings such as laboratories, computer centers and residences.
