Traditionally, the equipment portion of these sales represented the largest opportunity. Currently, however, suppliers have been focusing more on services, which provide ongoing revenue streams, as opposed to equipment sales, which represent one-time purchases.REASONS FOR DOING THE STUDY Several forces are driving trends toward increasing levels of automation of systems that provide essential services in buildings, as well as the centralization of controls for these systems. Higher levels of automation are essential for maintaining the profitability of buildings, controlling the operating costs of all buildings and ensuring competitiveness of buildings in areas where tenants have other options for residence. The development, proliferation and flexibility of microprocessor-based controls, interface devices, distributed actuators, standardized network protocols, computerized interfaces and wireless communications have presented an opportunity for highly automated centralized building control systems. Residential building automation systems are usually installed at the onset in new buildings, and integration suites are becoming increasingly common in major renovations where new systems such as structured cabling are being put into place. This study explores national and international building codes and standards, the major manufacturers of building automation equipment and component systems, and the technologies involved in those systems. Standardized network protocols, interfaces, personal computers (PCs), handheld wireless devices and distributed touch pads are providing the primary human interface elements for building automation systems. The strength of the world building automation market relies on the health of local or regional construction markets. This, in turn, depends on world, regional and national economies. Consequently, sales of these products have been largely seen in the world's more advanced business epicenters: Europe, the U.S., China and Japan. This study analyzes the most prominent markets for these systems and breaks it down into four sections: Europe, North America, Asia (including Australia), and South America and Africa. The market's economic potential is framed in the context of the construction market for each area examined and then consolidated to provide a complete picture of the market. Extensive investigations have also been carried out to quantify the size of the market in five areas: residential home automation systems, HVAC, lighting, energy management and security. This was done to aid marketers, manufacturers, system integrators, contractors and other parties involved in the residential building automation industry to better direct their efforts at presenting their products and services to the most promising markets.
