From device to the cloud: approaches and challenges in getting HVAC&R data from remote devices

There is strong demand for HVAC&R monitoring and metering solutions that incorporate cloud data collection and real-time or near-real-time cloud-based control. This is enabled by reductions in the cost of sensors and meters, advances in communication technologies, the development of the Internet of Things (IoT) as a lower-cost alternative to traditionally vertically integrated systems, and the move to more frequent data collection.

Planning for carbon neutral in existing buildings

This paper explores the role of optimisation of existing infrastructure, onsite renewable and non-renewable generation, hardware changes and energy-procurement activities in achieving carbon neutral status for a mixed-use building in Melbourne, with consideration to moving electricity and gas grid factors (cost and emissions) across 15 years.

Next-generation fault detection for commercial building HVAC systems

Modern commercial buildings are becoming more complicated as the number of sensors, actuators and control loops increases. The building management system (BMS) used to control these components will often generate equipment faults and anomalous behaviour, which causes energy waste, thermal discomfort, and drives up maintenance costs. Such system failures may last for a long time before a facility manager or technician notices them. This necessitates the use of automated fault detection and diagnostics (AFDD) tools to detect operational faults and identify their root causes to ensure fault-free operation.
