Buildings and building systems are undergoing enormous change globally, nationally, and locally. In New York City, where buildings represent as much as 50% of city energy use and are an essential locus of value in the city’s economy, technicians and technical service organizations face many of the same issues that confront other public and private sector organizations: rapid technology change, an ongoing revolution in information technology, expectations of improving levels of service, demanding mission-critical requirements, and pressures for reduced energy consumption. The surge in interest in and development of Green High Performance Buildings represents this trend, which requires increased knowledge, skill levels, and professionalization on the part of the workforce.
