Another step involved developing a quantitative understanding of the characteristics of residential construction industries in different regions of the world. In addition, assessments were made of regulatory policies governing each region with respect to requirements for residential building automation systems. This was done with varying degrees of granularity, keeping in mind that special codes are enforced in different nations.A summary understanding of the markets was developed for component systems of various residential building automation systems. With this information in hand, trade publications and Internet searches were performed, along with interviews with industry representatives, regulators and legislators to discern trends in the extent of implementation of fully-integrated building automation systems. Attention was also paid to activity in the markets for systems that integrate disparate component systems. In this regard, networking and data transfer capabilities of the product lines of various component system vendors were taken as an indication of manufacturers' thrust toward integrated, or integratable,systems. Revenue from the various building automation products comes from two sources. New construction is one source. Analysts estimate that building automation elements account for 2.5% to 3.5% of the total construction project value for new homes. The revenue includes both equipment and services. In addition, owners decide to renovate their residences to make them more attractive. For this report, building automation revenue was divided into equipment sales and consulting services associated with these projects. The market for these products is shifting, with equipment accounting for a smaller percentage of a vendor's revenue and consulting services accounting for a higher percentage. Consequentially, suppliers are not only trying to develop strong products, but they are also building up their distribution channels. The world economy has become increasing complex, volatile and difficult to forecast. The financial projections in this report came from projections from various economic monitoring groups, including the International Monetary Fund (IMF), the World Bank and the CIA World Fact Book. Input from these various sectors was used to complete the five-year market projections. All revenues are expressed in U.S. dollars.
