Initially work was carried out to develop and utilize an inexpensive, open-source system for measuring, storing, and displaying energy related data from across campus. Hardware and software components chosen were open source or free for educational use. A low power Linux server was utilized. The LAN-enabled Arduinos included sensors to measure energy related quantities such as power and temperature. EE and CS students were engaged in various aspects of the project-EE students focused on the hardware, CS students focused on the programming. EE junior students worked with clients to implement real world measurement and display solutions. A CS student project focused on developing a JavaScript-based web page that visualizes sensor data by leveraging CanvasJS and JQuery packages. This web page development project will continue in spring 2016 as the work is significantly incorporated into the CS department's Software Engineering and Information Technology Systems classes. Most recently, EE junior projects (fall 2015) emphasized collaborations across a wide variety of disciplines: projects include wetland environmental factors (Biology), greenhouse environmental factors (Biology), pump energy usage (ME), weather monitoring (Physics), and classroom temperature monitoring (Facilities).

The primary RE education efforts have been through the department of Electrical Engineering (EE), with involvement from the department of Civil Engineering. In summer of 2009 the college installed a solar hot water (SHW) system in one of its student townhouses. The subjects of the advanced EE elective “Energy Measurement and Display” in summer 2009 were the selection of sensors to measure energy delivered by this SHW unit, and the uploading via Ethernet of real time data to a central server. The EE department requires all students to take “Embedded Controller Design”, and as a sequel a PIC based independent study focusing on sensing and evaluating energy consumption is presently under way. A number of Energy Savings and Power Quality independent studies have taken place over the past several years, with students developing embedded applications for measurement and assessment of don...

Two methods were used in this evaluation: measurement and modeling. We measured the building wiring as a source of magnetic fields in six multifamily developments in Michigan. In this small sample, building wiring proved to be an important source of exposure in four of the six cases. In all four cases with exposure from building wiring, one or more NEC violations were involved. To supplement our measurement efforts, we used computer modeling to compare magnetic field exposure due to building wiring with magnetic field exposure from external power lines. Our calculations showed that where the building wiring has a NEC violation leading to net current loops, the exposure due to wiring is likely to be more important than that from external power lines. Our results support the results obtained in a recent study of the exposure of Californian K-12 students to magnetic fields, where building wiring with one or more NEC violation was found to be the single most important exposure source. If 60 Hz magnetic fields are important to avoid, then improved enforcement of the NEC, as required by law, is perhaps the single most important mitigation policy to adopt.
