Feasibility study of wastewater energy transfer for an existing campus building cluster

The HVAC-related energy usage of a group of three existing buildings on a Canadian university campus (the “Cluster”) was simulated. Two scenarios were compared: (1) an ambient loop paired with conventional HVAC equipment (boiler plant and cooling tower), and (2) an ambient loop using wastewater energy transfer (“WET”). The study aimed to assess the feasibility of implementing WET as a heating and cooling method for cold-climate institutional buildings, as well as to measure the effects of WET implementation on energy usage, greenhouse gas emissions, and energy costs

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.

Courting expansion

Playing predominantly out of MyState Bank Arena in Hobart, the Tasmania JackJumpers have, in just two seasons, quickly become one of the National Basketball League’s premier teams. Sean McGowan reports on the award-winning redevelopment of the venue, which took place ahead of the team’s debut in late 2021.

Cool for school

Cool for school

Effective learning spaces that maintain optimum indoor environmental quality and inspire students to learn form a critical component of educating our youth. As part of the i-Hub initiative, a collective of designers, engineers and architects explored how integrated design might benefit ACT schools.

Good management systems matter

The adoption of a prefabrication strategy in the design and construction of mechanical services systems at the new Victorian Heart Hospital in Clayton solved numerous challenges associated with the build and project timelines. As Sean McGowan reports, the approach is a precursor to future healthcare projects.
