Building Monitoring System (BMON)

BMON Information

You cannot manage what you don’t measure, and what you don’t manage can cost you. That is why the Alaska Housing Finance Corporation (AHFC) developed a free open source building monitoring system that measures real-time energy use and provides a complete summary of operating performance. The system is able to track building occupancy, temperature, electricity, and fuel use as well as access data from multiple sources, including established weather stations, building automation systems, databases, and other points. 

Reduce energy consumption and improve operation and maintenance efficiencies through: 

  • Comprehensive monitoring, troubleshooting operational difficulties, and early warning detection sensors 
  • Coordinating morning warm-up times, sequencing of boilers, identifying electrical spikes, and optimizing the building’s fresh air supply

Alaska Housing realized close to 18% energy and cost savings after installing a building monitoring system on its Anchorage office building. To explore Alaska Housing’s near real-time building data visit

Alaska Housing Building Monitoring System benefits:

  • Access from any web-connected computer
  • Explore multiple options to display data including graphs, spreadsheets, scatter plots, and more.
  • Download the non-proprietary and open source system for free.
  • Give access to multiple operators with different capabilities to monitor the visual dashboard.
  • Monitor real-time energy flows, determine the energy costs of specific systems and identify cost-saving opportunities.

BMON sites in Alaska

  • AHFC – AHFC funded the creation of the BMON source code through the DOE State Energy Program and continues to upgrade and maintain the system. BMON is used in many AHFC facilities, public housing, and organizations that serve the public to improve the efficiency of building operations, prevent freeze-ups and provide data to building managers and decision makers. 
  • ANTHC - The ANTHC staff and rural utility operators use BMON to record a wide array of utility data and identify anomalies before they become potential catastrophic failures. The recorded utility data is also used to study daily utility operations to assist in water treatment optimization, determining energy conservation measures and future utility upgrades/improvements. 
  • YKHC - YKHC uses BMON to track energy use and prevent failures in 36 clinics across the Yukon Kuskokwim region
  • Analysis North – Analysis North is the primary BMON developer and can set up new systems as needed.
  • Seward Watch – A web service that offers tools to monitor boats and buildings in Seward at a low-cost.
