st21zzzzzzCentury BuildingsPurpose of a building is to provide a controlledenvironment for occupants.Building is a collection of systems that provide acontrolled environment.Systems’ integration is the key to effective and efficientbuilding operations.Buildings will be optimized as a system.Traditional approach: optimize building subsystemsleaving building suboptimal.Building quality will be measured by its ability toefficiency support the activity it houses - not its utilitybills.HVAC Systems Establish Environment
