The business case for sustainable office buildings

The market for sustainable buildings has rapidly gained momentum in the design and construction phases, however it appears that development and investment in these buildings by the private sector is limited. This is further complicated by the limited information available confirming the financial viability of sustainable buildings, with relatively little research conducted into the relationship between sustainability and the market value of commercial buildings. Currently the demand for sustainable buildings in Australia and New Zealand is being encouraged through government legislation and policy, where investment by the private sector has been relatively slow to develop due to the lack of evidential proof of the economic viability of sustainable buildings. Clearly if the progress and uptake of sustainable buildings is to develop within the property market, it is essential that the relationship between market value and sustainability should be understood in order to fully inform the investment industry.

Mussolini and the idealisation of empire : the Augustan exhibition of Romanita

The Augustan Exhibition of Romanita`, held in Rome’s Palazzo delle Esposizioni between 1937 and 1938, exemplifies the aestheticisation, ritualisation and sacralisation of politics during the Fascist era in Italy. This article conducts a multi-layered spatial analysis of the exhibition that considers space as passively experienced, as an agent to re-map memory, as a mediator between intention and reception and as having both physical and mental characteristics. The relative sizes of the spaces, their sequence and their axial placement within the Palazzo’s plan were the most powerful forces that conveyed the exhibition’s overall political and social aims. The Mostra Augustea della Romanita` (MAR) is here analysed as a form of historical representation with a specific narrative which is played out within an orchestrated space in order to create and reinforce a (Fascist) political identity. The idea of Rome took on material aspects through a kind of ‘recognition effect’ for the visitor by presenting Romanita` as a collective mirror in which to view an image of their own social visage. Thus an active connection would, according to the organisers, be forged between a Roman past and a Fascist present, and its two leaders and creators, Augustus and Mussolini, as well as between the individual and society. The MAR also demonstrates the prevalence of the cult of Il Duce in Fascist society and its importance for maintaining high levels of consent. With its focus on a particular view of the ancient world, the MAR was an ephemeral event that acted as teleological justification for the advent and supposed permanence of Fascism, which at the same time presented itself as a unique archaeological, scientific and educational document of the Roman world.

Examining and quantifying the drivers behind alterations and extensions to commercial buildings in a central business district

The drive to undertake building adaptation has increased in momentum, the primary reason being adaptation can be less expensive than new build and conventionally result in faster project delivery times. The issue of sustainable development is another clear driver for adaptation and collectively buildings contribute around half of all greenhouse gas emissions. At the same time governments seek effective and efficient ways of reducing the contribution of cities to climate change and building adaptation appears to offer a practical means of reducing building-related emissions. One example is the ‘1200 building program’ which aims to increase adaptation rates with a target of 1200 city centre office adaptations by 2020 as part of the strategy to achieve carbon neutrality. Through a longitudinal examination of building adaptations it is possible to identify the nature and extent of typical levels of adaptation, as well as determining the inter-relationship between different types of adaptation and building attributes. Melbourne city centre was used for a case study which analysed 5290 building adaptation events between 1998 and 2008. The findings promote the adaptive reuse of buildings in specific circumstances and are directly applicable for increasing sustainability in the built environment. The case study focused on existing buildings in a global city to ensure relevance to urban centres where existing commercial buildings can become part of the solution to mitigate climate change.
