Task-ambient control systems provide personalised comfort to individuals while maintaining acceptable environmental conditions in the ambient space. Occupants can adjust their local environment settings while saving energy and reducing loads. iSPACE is a system which uses a radiantly cooled workstation table; a smart hub with task light, task fan and an array of sensors (Lux, Temperature, Rh, PIR Occupancy & CO2); and a smart power strip. This strip uses a regression based intrusive load monitoring technique to identify and control the connected loads. The occupants can monitor their energy consumption and loads through a mobile app.
During a demand response event, every individual gets a load budget. The hub controls the system in response to this budgeted load and targeted comfort levels. The occupant may adjust comfort levels (thermal/visual/plug loads) to achieve the budgeted limits. The occupant can also trade excess/deficit load with other occupants. iSPACE uses an open architecture transactive network framework to facilitate these trades.
Dr Vishal Garg is Associate Professor and Head of the Center for IT in Building Science at IIIT Hyderabad. His current research interests are in the areas of building energy simulation, building automation, and cool roofs. He teaches building automation and controls, energy simulation, and illumination engineering. He has conducted several national and international workshops on intelligent buildings, green buildings and energy simulation. He holds a B.Tech. (Hons.) Degree in Civil Engineering from MBM Engineering College, Jodhpur and a PhD from IIT Delhi. He is actively involved in the green building movement, development of e-toolsfor advancing energy efficiency in buildings, and development & implementation of energy conservation building code. He was the founding president of the Indian chapter of International Building Performance Simulation Association (IBPSA) and chaired the organising committee of the international conference- Building Simulation-2015. He is the lead authorof the recently published book “Building Energy Simulation: A Workbook Using DesignBuilder”.
