<p>The recently exhausted Three Kings Quarry in central Auckland suburbia is currently being prepared for housing development. As a suburb within New Zealand’s fastest growing city, housing pressure and intensification policies mean that higher density design will be a key focus of remediation. Medium Density Design is a relatively young model of higher density housing in New Zealand and has developed a strong negative stigma, engendered by the abundance of unresponsive medium density developments which struggle, both physically and visually, to connect with Auckland’s low density suburban culture. Plans to only partially fill the site have been met with opposition by the community as the quarry landscape is seen as an obstacle for connection within the suburb and unfit for human inhabitation. Because of these negative feelings towards both the quarry and medium density design, locals are anxious any development within the quarry will follow a similar Medium Density housing model that turns its back on its context and community while failing to connect to the Three Kings context.  This research argues that by designing with the slope and existing condition of the quarry, medium density design can produce a scheme that meets the desires of the community and builds a unique and relevant identity for Three Kings. This thesis proposes this can be achieved by acknowledging the significance of the industrial landscape and designing with landform features and environmental systems; through community focussed medium density design; and by taking advantage of opportunities of mass housing design on the slope. These issues are tackled on the urban scale through design of a master plan, as well as cluster and dwelling scale design proposals.</p>

Design Changes

This paper aims at explaining testing procedures used to evaluate the potential of natural ventilation and daylighting applications to passive design of housing in Ghana. The objectives of research were to reduce energy costs and increase the sustainability of housing. From the results of these experiments actual and potential designs are illustrated and discussed. Mass housing results in multi-storey buildings which require substantial artificial lighting and ventilation. Also, with the increasing usage of glass for windows and doors in Ghana, even the shaded depths of buildings require additional daylight usually resulting in more energy consumption. By supplementing the internal lighting levels with daylight, reducing the internal heat load by shading windows to direct radiation and the utilization of natural ventilation over air conditioning where possible, significant energy savings are could be achieved. The research proposes mass housing design changes such as: delivering daylight above the suspended ceiling into the depths of the building by horizontal light pipes and natural ventilation, utilizing stack effect and wind siphonage, etc.

Compact Development

<p>This thesis investigates the scope for compact development to accommodate population growth in Wellington, New Zealand. The topic is particularly significant for New Zealand as the great majority of the population lives in urban areas, historical development has been dominated by low density urban form, and transport and urban form are two of the main domains in which the country can reduce its carbon emissions. The influence of urban planning and residents’ preferences on achieving sustainable outcomes is investigated.  Historical and current planning rules and transport policies in the City are analysed to determine their influence on the provision of compact development. Wellington’s transport policy shows a pattern of path dependency: historical decisions to favour car oriented investment have driven subsequent transport investments and influenced the ease of using different transport modes. Planning policies show a similar pattern of path dependency: planning rules enacted in the 1960s endure in present planning despite being packaged with different justifications and regulatory regime. Current planning rules severely restrict infill development in most existing neighbourhoods, which reduces the availability of housing in accessible medium density neighbourhoods and likely increases the cost of this type of housing.  A stated choice survey was conducted of 454 residents of Wellington City to investigate the extent to which there is an unmet demand for compact development and alternatives to car travel. The survey held presentation mode constant across two completion modes (internet and door to door with tablet completion), allowing the impacts of recruitment and completion mode to be examined. Survey recruitment mode appeared to influence both response rates and the representativeness of the survey, while completion mode appeared to have little or no impact on survey responses.  Using the stated choice survey results, a latent class model was developed to examine the preferences of residents and the trade-offs they are willing to make when choosing where to live. This type of model allows for the identification of preference groups as a means of understanding the diversity of preferences across the population. The study found that there is an unmet demand for medium density, accessible housing, but that affordability is a barrier for households to choose this type of housing. There was also an unmet demand for walking and cycling, with more residents currently driving than would prefer to use this mode, and more residents preferring to walk and cycle to work than currently use these modes. The ability to use a desired travel mode appears to be related to the neighbourhood in which a person lives, with residents of medium and high density neighbourhoods being more likely to use their preferred travel mode.  This study also modelled future development trajectories for Wellington based on demand for housing, neighbourhood and transport attributes. This preference based growth model was contrasted with the City’s plan for development over the next 30 years. Comparing the two scenarios, the planning based trajectory performed better than the demand based scenario in terms of both carbon emissions and achieving compact development.</p>

Thermal Bridges

The paper presents calculated values of increase of thermal transmittance because of thermal bridges (ΔU value) of panel residential houses of mass housing development. These values are compared with general values, which are given in the standard STN 73 0540-2 and afterwards a specific energy need for heating considering exact ΔU values but also general ΔU values was calculated as well. The residential houses were evaluated in original state and in state after the renewal by adding thermal insulation on walls, roof and after replacement of windows.
