Unsafe leased residential premises: a landlord's liability in negligence to injured occupants

This article examines the law relating to the liability of landlords in negligence for unsafe residential premises, focusing in particular on the recent High Court decisions in Northern Sandblasting Pty Ltd v Harris and Jones v Bartlett. The author concludes that the High Court in Jones v Bartlett has placed sensible limitations on landlords' liability, by limiting liability to defects in the premises that were known or ought to have been revealed on a reasonable inspection by the landlord. The author points out that there are compelling policy considerations supporting the court's conclusion in that case that the landlord should not be required to arrange for the premises to be inspected by expert tradespeople.

Enforcement of arbitral awards where the seat of the arbitration is Australia, how the Eisenwerk decision might still be a sleeping assassin

This article examines the enforcement of foreign awards in Australia. It identifies and explains the difference between a “foreign award” and “international arbitration award,” observing it is a somewhat surprising but potentially significant distinction. The article then moves to consider the consequences of the distinction with particular reference to the Australian arbitral landscape. Australia has dual arbitration regimes operating at the state and federal level. Particular attention is given to the still controversial Queensland Supreme Court of Appeal decision in Australian Granites Ltd. v. Eisenwerk Hensel Bayreyth Dipl-Ing Burkhardt GmbH. The article concludes by promoting a line of interpretation that will effectively allow subsequent courts to avoid the potentially disastrous effects the Eisenwerk decision may yet still wreak.

Combined evaluation of workplace performance using occupants' subjective assessment and objective measurement of environmental conditions : a case study

The case study presents findings from a program of pre- and post-evaluations of buildings sponsored by the NSW government. The program aims to demonstrate leadership in the delivery of government accommodation and to provide feedback into the building design and management process.

The results from a combined evaluation of an ABGR 4.5 star government building using the KODO probe© occupant surveys and measures of environmental conditions, carried out by the Mobile Architecture and Built Environment Laboratory (MABEL) at Deakin University are summarised. In particular the paper will present the benefits of innovative performance evaluation of property for commercial benefit using the KODO productivity topographic maps©.

These maps isolate where facility solutions are needed as opposed to tenant/occupant solutions in order to optimise building and business outcomes with minimal capital investment.

Balancing buildings and occupants - a holistic approach to thermal comfort and greenhouse gas emissions in mixed mode offices

This paper describes a holistic approach to comfort and greenhouse gas emissions in mixed mode offices. It is based on parametric studies for a typical cellular office in the Mediterranean climate of Athens, Greece, using building simulation.

Considered parameters are the influence of different building design, varying occupant behaviour and internal heat loads, as well as of an exceptionally hot summer. Additionally, the performance of a cooling strategy following the comfort limits according to the EN 15251 adaptive model is compared with the common fixed cooling set point 22°C.

The performance of mixed mode offices is evaluated regarding thermal comfort, daylight autonomy and related greenhouse gas emissions. Results indicate strategies to improve sustainability in mixed mode offices in Athens, by balancing the influencing parameters.

On the influence of building design, occupants and heat waves on comfort and greenhouse gas emissions in naturally ventilated offices. A study based on the EN 15251 adaptive thermal comfort model in Athens, Greece

According to the Intergovernmental Panel on Climate Change the buildings sector has the largest mitigation potential for CO2 emissions. Especially in office buildings, where internal heat loads and a relatively high occupant density occur at the same time with solar heat gains, overheating has become a common problem. In Europe the adaptive thermal comfort model according to EN 15251 provides a method to evaluate thermal comfort in naturally ventilated buildings. However, especially in the context of the climate change and the occurrence of heat waves within the last decade, the question arises, how thermal comfort can be maintained without additional cooling, especially in warm climates. In this paper a parametric study for a typical cellular naturally ventilated office room has been conducted, using the building simulation software EnergyPlus. It is based on the Mediterranean climate of Athens, Greece. Adaptive thermal comfort is evaluated according to EN 15251. Variations refer to different building design priorities, and they consider the variability of occupant behaviour and internal heat loads by using an ideal and worst case scenario. The influence of heat waves is considered by comparing measured temperatures for an average and an exceptionally hot year within the last decade. Since the use of building controls for shading affects thermal as well as visual comfort, daylighting and view are evaluated as well. Conclusions are drawn regarding the influence and interaction of building design, occupants and heat waves on comfort and greenhouse gas emissions in naturally ventilated offices, and related optimisation potential.

"Tomorrow's car" : Deakin Universities new cross vehicle that combines the best of 2 worlds

Motorbike riders are 34-times more likely to die in a crash compared to car drivers per km travelled (1). Such safety risks together with special skill requirements for the driver and much lower comfort compared to normal cars are the main reasons why motorbikes represent only a fraction of all vehicle sales in developed countries. Deakin University is developing a revolutionary cross-over fun vehicle with ultra low fuel consumption and emissions. This new vehicle generation combines the best of two worlds: the fun to drive, low cost, and small size of a scooter together with the safety, comfort and easiness to operate of a car. The result is a vehicle that is more fuel efficient than most cars or even scooters.

Various tilting cross over vehicles have been presented over the last decade that were trying to automate the tilting control of narrow vehicles to make them safer. Examples of these concepts are the Carver, Clever and in some way also the MP3 scooter from Piaggio. The problem with fully enclosed concepts like the Carver or Clever is that they require very complex and therefore also expensive tilting control systems so that the vehicles are not price competitive compared to low cost micro cars or even normal small cars. The MP3 on the other hand comes with a tilting control system which is only semi automatic so that typical car advantages - comprehensive safety features like crush zones, roll over protection, air bags, safety belts or comfort features like full weather protection including heating and cooling – can not be provided.

Deakin’s approach is quite different to the above mentioned concepts. The requirements were derived based on two different investigations: The first step was a critical evaluation of social trends and the second step was an in-depth benchmarking study of existing concepts which identified the typical strengths and weaknesses of these concepts. In a critical next step a new concept was created that addresses most of the weaknesses of existing tilting three-wheelers in a holistic approach by setting clear priority rankings for the vehicle targets, based on current trends. The priorities were set in the following order: Safety, Affordability, Fun and Efficiency (SAFE).

The key feature that enables an enclosed tilting vehicle is a fully automatic tilting control system. With an automatic tilting control system the driver does not need to put the feet on the ground to balance the vehicle when he stops, so the vehicle can be built with a full enclosure. This allows the implementation of typical car like safety features (seat belts, roll over structure, crush zones, air bags). The SafeRide™ tilting control system is a passive system that involves the driver’s balancing sense in its feedback control system. The vehicle has typical scooter like steering characteristics, where the steering is initiated through countersteering. Another safety critical design feature is the crush zone between the two front wheels which is not possible with only one front wheel or with the powertrain positioned between the front wheels, as the powertrain can’t absorb a lot of energy due to its structural stiffness and density. The passive tilting control system is quite simple and therefore makes the vehicle very affordable, an important factor for successful commercialisation.

Another advantage of integrating the human balancing senses in the feedback control of the tilting system is that the system kicks in slightly after the human balancing reacts. In some instances that can generate the typical adrenalin thrill known from riding a bike. This fun factor is quite common with many trend sports like mountain biking, surfing, roller-skating, snowboarding, or skateboarding. Some of these sports have seen very rapid growth only a short time after they have been invented. Utilising the human balancing system during driving also makes the vehicle safer as the adrenalin is produced after reaching a semi-stable driving condition that is controlled by the vehicles tilting control system, but before the vehicle reaches an unstable driving condition that can not be controlled by the vehicle but only (eventually) by the driver – if he has got the required driving skill and if he is alert enough.

Efficiency superior to most cars and scooters is achieved by the aerodynamics of a fully enclosed body structure in combination with the small frontal area of a typical scooter and the droplet shape enabled by the relatively wide front with 2 wheels and the very narrow tail with only one rear wheel. The passive tilting system also contributes to the extreme efficiency as the system only draws some small electrical power for the electronic control unit. Another feature is a low cost exhaust energy recovery system which is discussed in another paper.

The influence of various seat design parameters: a computational analysis

Nowadays, low back pain becomes a common healthcare problem. Poor or unsuitable seat design is related to the discomfort and other healthcare problems of users. The aim of this study is to investigate the influence of seat design variables on the compressive loadings of lumbar joints. A basis that includes a musculoskeletal human body model and a chair model has been developed using LifeMOD Biomechanics Modeller. Inverse and forward dynamic simulations have been performed for various seat design parameters. The results show that the inclination of backrest and seat pan may or may not decrease the compressive spinal joint forces, depending on other conditions. The medium-level height and depth of seat pan and the medium-level and high-level height of backrest are found to cause the minimum compressive loads on lumbar joints. This work contributes to a better understanding of sitting biomechanics and provides some useful guidelines for seat design.

A manufacturing process using the infrared ray local heating method for seat cross members

Recent studies have shown that the infrared (IR) local heating method drastically reduces springback of advanced high-strength steels (AHSSs). Though the IR local heating method saves heating energy because it utilizes focused IR rays to heat only the plastic deformation zone, there has yet to be an attempt to show that the heating method can be applied to industrial manufacturing processes. In this work, the IR local heating method is used to manufacture a seat cross member. Seat cross members require high strength because they are responsible for protecting passengers from broadside collisions. Although AHSS is preferred in seat cross members, the large amount of springback of AHSS makes a problem in the accuracy of the shape. This work verifies that the IR local heating method is able to make the seat cross member with the target shape in the manufacturing process. A thermo-mechanical analysis was also conducted with the finite element method to discuss the springback results.

Politicised pagodas and veiled resistance : contested urban space in Burma.

The urban landscapes of Yangon and Mandalay in Burma (Myanmar) exhibit a rich cultural layering and complex blending of urban forms and architectural styles. But while both cities today are shaped by contemporary economic and political realities, they also clearly reflect
their historical origins—Yangon as the British colonial capital and Mandalay as the last seat of the monarchy. Burma’s ancient religious monuments, monarchical and colonial heritage on the one hand, and new religious edifices, international standard hotels, commercial enterprises, new public buildings and satellite towns on the other hand, represent the two poles of the dialectic of tradition and modernity. The landscapes, as symbolic representations, have been appropriated by
the authoritarian military regime, the State Peace and Development Council (SPDC) for nation building purposes. But the urban landscapes are also contested and appropriated in symbolic ways and invested with meanings as sites of resistance and struggle by those in opposition, and
are thus contested sites where the power relations of domination and resistance intersect. The paper illustrates these themes with examples drawn from Yangon and Mandalay.

Applying the adaptive model of comfort

This note is directed to one major aspect of the comfort of building occupants – namely, thermal comfort. Even though it may be difficult to isolate thermal sensations from the whole of comfort itself, humans have a strong physiological connection with their thermal environment. Our thermal perceptions and sensations often vary greatly, especially between our indoor and outdoor environments. We may be totally comfortable lounging under a shade cloth on a 35°C day with a stiff breeze enveloping our body, but would never tolerate similar conditions indoors. Such divergent perceptions of the same thermal stimulus across differing contexts raise countless questions about just what the determinants of thermal comfort actually are, and how they may be managed against the demands for an environmentally responsive architecture.
