Summary:

The research aims to identify the types of building defects impacting residential buildings, the effects that building defects have on buildings and residents, the impact of the regulatory environment and how defects are managed by the owners corporation. The study identified the prevalence of building defects based on construction systems. Defects were most prevalent in following systems (in order): building fabric and cladding, fire protection, roof and rainwater disposal, waterproofing and structural.

Summary:

Apartment buildings offer an opportunity to apply central battery storage and shared solar generation to aggregated apartment and common loads through an embedded network or microgrid. We present a study of energy and financial flows in five Australian apartment buildings with photovoltaics and battery storage using real apartment interval-metered load profiles and simulated solar generation profiles, modelled using an open source tool developed for the purpose.

Opportunities and barriers for photovoltaics on multi-unit residential buildings: reviewing the Australian experience

Summary:

This paper reviews opportunities for, and barriers to, increasing photovoltaic (PV) deployment on apartment buildings. We undertook a review of the academic literature and of specific Australian regulatory arrangements, as well as conducting interviews with relevant stakeholders. Barriers identified include the huge variety amongst apartment building stock, demographic factors and knowledge issues. However, the Australian regulatory context – including governance of apartment buildings, regulation of the energy market, and electricity tariff policies – also impacts on the options available.

Photovoltaics on Apartment Buildings

Summary:

Although Australia has over 2 million solar households, the 10% of Australians who live in apartments are still missing out on cheap, clean energy. This final report from CEEM's three-year research project includes an assessment of the scale and nature of the solar opportunity and analysis of the costs and benefits of different technical configurations and financial arrangements. It also identifies some of the challenges preventing apartment residents from installing solar PV and suggest some policy reforms that could help overcome the key regulatory barriers.

Summary:

In the 21st century Australian city, urban renewal has become synonymous with higher residential densities. This chapter discusses: the potential for conflict; problems of building design, build quality and defects and ongoing problems with major repairs and maintenance; strata ownership as a formidable barrier to further renewal in areas that otherwise would be prime sites for redevelopment. We draw on a series of interlinked and on-going research projects undertaken by the authors and colleagues over the last decade looking at aspects of the emerging strata title sector in Australia.
