Built environment

It’s like a jungle sometimes, but is the grass always greener for buildings that boast green walls and roofs? Laura Timberlake explores.

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.

Almost everyone who works on HVAC in Australia would be familiar with the AS 1668 series. Right now, AS 1668.2 and AS 1668.4 – which between them cover mechanical and natural ventilation in buildings – are open for public comment.

The owners of a Passivhaus residential development in Melbourne’s inner suburbs have adopted a pragmatic approach to design, ensuring the best possible outcome on a site overshadowed by neighbouring buildings. Sean McGowan reports.

Recent professional opinions on the use of AI in real–world building applications have raised some concerns with Alan Obrart, L.AIRAH.

Perched on a rocky crest in Mansfield, Victoria, Robbie J Walker’s off-grid house defies harsh weather conditions to heat and cool itself writes Nick Johns-Wickberg.

AIRAH’s Infection Control and Operating Theatre Practices Special Technical Group is taking a close look at hospital air quality guidelines.

Desiring to use actionable data from our buildings is undoubtedly a good thing. To effectively do this, however, defining terms and allocating responsibility for tasks is essential – especially when the “smarts” from our edifices exist in the space between systems.

What role does data play in the electrification of buildings? With a focus on machine learning, artificial intelligence and the interaction with the electricity grid, a panel at AIRAH’s recent Building Date Forum explored this fascinating topic.

Ultraviolet germicidal irradiation (UVGI) using electromagnetic radiation in the UV‑C wavelength band of 200–280nm can prevent the reproduction of microorganisms. Several factors related to UV fixtures, HVAC layout and the resulting airflow flow patterns can affect the performance of upper‑room UVGI applications.

Given the considerable amount of transport infrastructure under construction, on drawing boards and taking shape in the daydreams of ambitious politicians, the concept of zero carbon transport buildings is featuring heavily in discussions amount those concerned about sustainability for our stations.

A six-storey Amsterdam building comprising laboratories and office space incorporates sustainable thinking from every possible angle, writes Laura Timberlake.

The hot topic in the world of big data analytics right now is validation. We ask members of AIRAH’s Big Data and Analytics STG: What exactly is it, and why is it so important?

The Data-Driven Smart Buildings Symposium was held at the University of New South Wales earlier this year. Dr Stephen White, L.AIRAH, reports.

A major urban renewal project in South Australia is transforming the former Royal Adelaide Hospital site into a $2.2 billion world-class innovation district. As Sean McGowan reports, Lot Fourteen is bringing curated, collaborative research and business enterprises together to solve complex global challenges.

This paper examines the challenges associated with removing natural gas from hospitals and transitioning to all-electric systems. It emphasises the unique energy requirements of hospitals and the need to prioritise patient care and safety over energy efficiency.

Artificial intelligence (AI) is an area of computer science that emphasises the creation of intelligent agents, which are systems that can learn and act autonomously. AI deals with the question of how to create computers that are capable of intelligent behaviour.

With the release of a fast-tracked pathogen mitigation standard and updates to advice on building ventilation from the Center for Disease Control (CDC), the US seems to be taking the lead on indoor air quality. Ecolibrium asked three local experts for their views. Mark Vender reports.

In the GBCA’s Green Star Design and As-Built ratings, projects can now be allocated an extra point by doing a whole-building test – a good thing, according to Sean Maxwell.

An innovative building constructed a decade ago is aging gracefully – and usefully.
