From iconic super buildings to reimagined shipping containers, trends in building systems increasingly embody analytics, connectivity, and energy-efficacy technologies.

Low-cost sensors, for example, are behind a new generation of connected technologies. Connectivity optimizes building systems through monitoring the signal strength of connected devices and detecting radio frequency interference by humans or animals. This creates a new type of occupancy sensor that can count building occupants during an emergency, locate intruders during a break-in, or monitor a nursing home for problems.

Given that as much as 40 percent of a new building’s energy efficiency is lost within three years from a lack of proper operation and maintenance, the combination of sensors, submetering, and computer processing power has given rise to building analytics that can identify faults and rapidly diagnose problems, thereby saving time, energy, and money.

In the following examples provided by NEMA member companies, we look inside building systems to see legacy products (e.g., contact switches), new technologies (e.g., sensors), and techniques (e.g., building analytics) that work together to achieve high performance and sustainability.
