Energy mandates have placed increasing demand on all aspects of building performance and the green movement has solicited the integration of a plethora of new products, systems, and accredidation requirements that remain largely unmeasured, tested, or monitored over time.

Project FROG is a prefabricated, modular classroom designed closely with Loisos + Ubbelohde as energy and daylighting consultants, to produce a ‘net-zero’ energy building which is designed and produced as an architectural product; dozens have been and continue to be built throughout the United States. Loisos + Ubbelohde worked with Project FROG to develop a building monitoring system that could be integrated into every building they produce, in order to verify actual building performance, as well as automate optimization functions. Sensor arrays are organized throughout the building to provide data points to track energy use, system performance, heat distribution, and variables related to occupant comfort.

Internally at Loisos & Ubbelohde we produced a graphical dashboard to display building data, and all of the software architecture necesssary to database information from many buildings, through a cloud server accessible remotely. The system is capable of integrating building controls and actuation (windows, fans, shades, air handling, etc.), such that, the data archives can be mined to automate buliding systems and optimize performance or meet occupant’s personal preferences. The conceit is to give these buildings brains of their own, and there is no system on the market capable of integrating sensor networks, databasing, and automating systems based upon optimizing performance and occupancy comfort... which is why we did it ourselves.

I was responsible for the electrical engineering and system hardware architecture, as well as the prototyping, staging, development, and installation of the first two systems. Each system deploys over 40 sensors in a variety of locations and configurations depending on the monitoring package chosen, including temperature sensors, relative humidity, water & gas metering, C02, wind direction, wind speed, solar radiation, solar hot water, rain gauges, barometric pressure, occupancy sensors, and current transformers to monitor electrical consumption or production of all circuits.

In addition to the clear initial benefits of verifying & optimizing designed building performance, the system will serve as an invaluable platform for continual research in building science. The data will be gathered and archived from virtually the same building in climates zones across the United States, and the scale of the building is such that the variables affecting performance and comfort are distinct and few in number.
