The Iowa Nest Residence was recently featured in a presentation on Net Zero Energy buildings at the Trimble Dimensions conference in Las Vegas. Among other topics, the presentation covered the custom-built monitoring systems that measure temperature and relative humidity on an ongoing basis, as well as the eGauge system that monitors energy use at the circuit level.
