Building Automation Systems (BAS) are closely associated with the hi-tech and computer industry. Hi-tech industries by their nature are undergoing rapid changes, and are competitive. Evolution and a highly competitive market results in never ending changes to systems hardware and software, and changes of vendors' organizations (and sometimes of their owners) that are marketing and supporting such systems. DDC manufacturers introduce new products, on average, every five years and product upgrades annually. DDC systems provide a reliable hardware platform, sophisticated application programs, and are user friendly for operators and maintenance. Building owners--and users of BAS systems--benefit from the situation through competitive pricing. At the same time, they feel the pressure originating from frequent introduction of new systems and instability of the companies bringing them on the market. Vulnerability is further enhanced by owners' needs for long-term system support. Evaluating and pre-selecting a DDC system uses criteria based on three items related to long-term systems performance: system selection, system implementation, and system support. The selection process is based on clearly defined objectives, and a six-step selection process which is described in this article.
