Buildings and the atmosphere are intrinsically connected via cooling and heating systems. Global climate is projected to grow warmer, while an increasing fraction of the population living in urban centers. This introduces the challenge for new approaches to project future energy demand changes in cities....

The world's population is increasingly urban with more than half the global population already living in cities. The urban population is particularly affected by increasing temperatures because of the urban heat island (UHI) effect. Increasing temperatures cause heat stress in people, even when not directly...

Beyond expensive building and equipment upgrades and retrofits, re-commissioning (analogous to performing a comprehensive tune-up on your car) and automated fault detection and diagnostics (FDD) for building systems offer significant energy efficiency opportunities in commercial buildings.

With Heating, Ventilation & Air Conditioning (HVAC) systems...

There are calls for changes to the nation's building code to ensure homes are heat stress resistant in summer.

A study has found new 'energy efficient' homes can actually be less resistant to heat than older double-brick homes.

As a result, Australian's are...

In Australia, heatwaves are the deadliest natural hazard and a major driver of peak electricity demand. The disproportionately high peak demand increases electricity prices, causes occasional blackouts and exacerbates energy poverty, all of which limit one’s ability to use air conditioning. Meanwhile, increased energy efficiency...

Radiant cooling and heating has the potential for improved energy efficiency, demand response, comfort, indoor environmental quality, and architectural design. Many radiant buildings have demonstrated outstanding performance in these regards, and application of the technology in commercial buildings is expanding. However, there are no well-established...

This study compares the cost of operating the auxiliary components of an optimised standalone hot water fired absorption chiller, using mains grid electricity and an optimised standalone photovoltaic system. The cheaper source was further compared with using mains electricity to operate a conventional reverse cycle...

Australia’s homes are notoriously “leaky” – allowing the uncontrolled flow of heat into and out of the building. Our answer has been to put in more and more pumps, in the form of air conditioning. This is often promoted as a feature, rather than an...

The increased penetration of residential air-conditioners (AC); specifically vapor compression types, is regarded as one of the foremost causes of a dramatic rise in critical peak electricity demands requiring corresponding upgrades of electricity infrastructures. These upgrades requires heavy investments, consequently, driving up electricity prices. Solar...

To combat increasing electricity prices due to the high operating costs of conventional reverse cycle air-airheat pumps (RC-AA-HP), they can be powered by standalone PV systems as a radical demand side energy management solution. However, the heavy power consumption of their compressors necessitates very large...

The rising penetration of vapor compression air conditioning systems in Australian dwellings has raised the peak power demand. Consequently, the electrical infrastructure requires significant, costly upgrades that is invariably passed on to all end-users. Electricity network charges account for about half the cost of an...
