Building Monitoring System

You cannot manage what you don't measure, and what you don't manage can cost you. This is one reason the Alaska Housing Finance Corporation (AHFC) developed a free open source building monitoring system that measure 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.

AHFC realized close to 18% energy and cost savings after installing a building monitoring system on their Anchorage office building. To explore the AHFC near real-time building data visit
