Building Management Systems

A Building Management System (BMS) integrates hardware, software and communications to collect data, monitor use, predict operations, and prescribe automated responses to achieve optimum performance.

A BMS encompasses

  • Components that connect mechanical, electrical, power, communications, and lighting using sensors, monitors, actuators, controllers, communication technology, and other devices
  • Systems that optimize comfort, energy performance, safety, and security
  • Interfaces for configuration, initialization, system maintenance, fault detection, diagnostics, predictive maintenance, and continuous improvement

Increasingly, a BMS uses data from the Internet of Things (IoT), cloud-based analytic platforms, and artificial intelligence. This necessitates a high level of attention to data privacy and cybersecurity. A BMS may also reduce carbon emissions, improve grid reliability, conserve water, extend equipment life, and increase occupant comfort and productivity.

Members publish technical documents and advocate the use and benefits of building management systems among interested stakeholders. They also coordinates with NEMA's High-Performance Buildings Council (HPBC) and the Cybersecurity Council to create unified industry positions on legislative and regulatory issues concerning BMS adoption.


  • Promotes the adoption of technologies and systems that increase the energy efficiency, safety, resilience, sustainability, productivity, comfort, and security of federal, commercial, and multi-family residential buildings
  • Develops guidelines for integrating devices and systems (e.g., meters, lighting, and low-voltage power distribution) into a BMS
  • Promotes integration with demand response, electric vehicle charging, renewable energy production, and other emerging technologies
  • Coordinates with other trade associations and code/standards development organizations (e.g., ASHRAE, NFPA, UL, IEC ) to develop opportunities for BMS-specific requirements in energy, building, and other codes and improve building energy modeling tools
  • Coordinates specific BMS-related cybersecurity requirements, challenges, and activities with the NEMA Cybersecurity Council and other groups


  • Developers, owners, managers, contractors, and architects involved in construction of small, medium, and large buildings as well as single- and multisite campuses
  • Government entities that oversee certification and rating of smart and zero-net energy building
  • Mechanical, electrical, and plumbing (MEP) firms
  • Manufacturers involved in the Internet of Things (IoT), and Industry 4.0
  • Residences that employ solar and energy storage systems, electric vehicles and charging systems, and virtual assistant systems that connect thermostats, lighting, appliances, HVAC, entertainment systems, security systems, communications, and others
