In the almost 10 years since we launched with The Fifth Estate we’ve learnt three important things about offices, the topic we covered at our event in Brisbane on 27 March 2018, Bring Your Office to Life.
One is that offices are capable of huge sustainability gains; they can achieve massive cuts in energy and greenhouse gas emissions.
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.
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 air-air heat pump.
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.
The rapid adoption of reverse-cycle vapour-compression air-conditioning systems in residential buildings has produced an escalation in both total and peak electricity demand, necessitating a high level of investment in electricity infrastructure, and raising concerns over energy security and environmental issues.
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 and expensive standalone hotovoltaic (PV) systems.
The Green Building Council of Australia with the Property Council of Australia, Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH), Energy Efficiency Council, Facilities Management Association of Australia, City of Sydney, City of Melbourne and CitySwitch have produced a policy framework addressing the potential opportunities presented by increasing the energy efficien
This study evaluates the technological, economic, environmental, regulatory and social feasibility of adopting algae building technology in Sydney NSW Australia as a source of renewable energy. Interview with 23 stakeholders in the built environment illustrate the drivers and challenges associated with such technology.
One of the major obstacles to improving solar thermal cooling technologies is the high operating temperature requirements of most solar thermal cooling systems. This paper reviews recent advances that could reduce the required heat source temperatures for solar desiccant cooling to the range of 50°C–60°C. These approaches include (i) isothermal dehumidification (e.g.
