Better Resource Control Building operators and business managers also are exploiting the relationship between technology and the facility to achieve greater efficiency in resources. More precise occupant control reduces operating costs for each unit and makes the spaces more attractive in the marketplace. Daylight sensors automatically adjust supplemental lighting to keep general lighting uniform and to save power. Chiller and boiler optimization reduces excess capacities. Electric demand limiting and optimal energy sourcing protects against demand surcharges.
Water consumption is reduced through smart fixtures with proximity controls.
Above and beyond the communications capabilities and efficiency controls are smart life-safety systems, another integral component of smart buildings. Many corporations and institutions require higher security access control and surveillance. High technology production facilities are using computer-controlled building seismic dampers. Heat and smoke detection and emergency control of elevators, HVAC systems, and doors are all now commonly linked to computer systems analyzing data and adjusting systems controls. The big winners in the smart building scenario now developing around the world are building users and owners.
