Fire suppression systems, specifically for fully sprinklered buildings, have dramatically decreased the number of fire-related deaths over the years. Fire containment and suppression by sprinkler systems limit the spread of fire and increase evacuation time available for building occupants.
Sprinkler and standpipe systems are often combined, although the extent of piping used for sprinkler systems is far greater than piping used for standpipes. Sprinkler coverage requires that vertical riser piping and branch piping extend to all areas of each building floor.

Buildings are complex structures that must be able to breathe in order to make them safe and habitable for occupants. Introducing fresh air through ventilation systems provides a high level of indoor air quality. Air intake louvers are the links between the outdoors and the built environment.
Ventilation system design, system component technology, operation, and maintenance are critical to ventilation system
reliability and security. At the same time, ventilation systems will distribute airborne contaminants, biochemical hazards, and particles to all points throughout a building, posing serious potential health hazards.

Mechanical system and service inside building includes water system and ventilation system. Building occupancy is highly dependent on water source availability. Water for potable and non-potable uses, and make-up water for HVAC systems, is required under normal operating conditions. During emergency conditions, water is required for fire suppression.
Water sources vary for each building and could include a municipal water supply, private water supply, or supply from a well. Reliability of the water supply should be reviewed during a facility threat analysis and risk assessment. Depending on local conditions, an on-site water storage system may be required. Hospitals, research laboratories, utility generating facilities, and other mission-critical facilities are highly dependent on water availability. In such cases, alternative water sources should
be considered during facility planning and design.

Inside building there are three major services which are electrical service, mechanical service, and fire suppression system. Today lets have a look at electrical services.
The security of a building’s electrical service relies on the service provider and facility location. For example, in an urban environment, the system may be arranged as a network with services to a building consisting of multiple underground feeders, multiple transformers, and may have redundancy built into the integrity and reliability of the service. Alternatively, in a suburban or rural environment, may be transported by overhead transmission lines, asters and more accessible for human intervention.

Glass based wall exterior often used because of its flexibility, beauty, and off course the price is lower then covering all the building with other hard material.
The glass used in windows, walls, and doors is one of the most fragile materials in building construction. Windows, walls, and doors typically consist of a frame and infill. In commercial applications, the frame is generally made of aluminum and the infill consists of a glass plate product. System performance depends on individual component performance, the interaction of components, and their connections to the supporting structure.
