The Scope of building M&E 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.

Impact of Building M&E Systems Space planning Architectural Design Construction Cost High-rise Building Design Global Environments

Impact on Space Planning - The M&E 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

Impact on Space Planning

Impact on Space Planning - 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) Although the ranges are broad, they serve a basis for conceptual planning and budgetary

M&E 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, transportation needs, Height increases = Less usable space on the floor – more floor for stairs, elevators, structural elements, M/E shafts, etc M&E

Impact on Architectural Design

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% M&E Systems on Construction Cost Depends on: type of building Materials of building Standard of living Architectural design M&E systems selected

Impact on Operating Cost Includes; energy consumption, routine maintenance, repairs, replacements and utilities Building Structural components are usually long lasting M&E vs initial capital investment
