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.

- Daylighting controls maintain a constant level regardless of natural light.
- LED wall packs illuminate the perimeter and parking lot to avoid light trespass with no uplighting.
- Construction consisted of shipping containers that had reached the end of their useful life and the building’s orientation considered wind currents to better ventilate spaces.
- The Three corporate office produces all the energy it consumes through solar panels.
- Rainwater and air conditioning condensates are directed to water tanks.
Danfoss Drives Factory
Loves Park, Illinois
- The LEED-certified Danfoss Drives factory manufactures fractional- through megawatt-variable frequency drives. The state-of-the-art building facilitates energy savings, prevents waste, and encourages innovation.
- Variable-frequency drives that reduce airflow and water flow were installed on all pumps, motors, and rooftops.
- Rooftop solar panels generate power that is used to produce Danfoss products.
- The entire facility is operated with a building management system that controls and monitors all HVAC systems.
- Installation of lighting controls on the production floor allows the facility to operate plant lighting based on production schedules.
