<p>Held every two years in Washington DC and run by the US Department of Energy the Solar Decathlon is a competition that challenges architecture and engineering students from all over the world to come up with new and innovative ways to design and construct low energy homes. For the first time in the competition’s history a team from New Zealand was selected to compete in the 2011 competition. This thesis documents the design process of the First Light house from concept to construction focusing on the relationship between energy and architecture in a New Zealand home designed for the Solar Decathlon. The challenge for the young architects and engineers competing in the competition is to develop ways of reducing energy consumption and to raise awareness of the energy saving benefits of highly efficient home design to the public. Despite this being the underlying philosophy, this thesis suggests that the competition is structured in a way that rewards technology over passive design innovation in architecture. A typical Solar Decathlon house is epitomized by a large solar array generating the power needing to run an oversized mechanical system. The New Zealand entry challenges this trend with the design of a home that is focused on ways to improve passive strategies for reducing energy use first before relying on technology. The question is whether a home designed with this philosophy in mind can still meet the strict requirements set out in the ten contests embedded in the Solar Decathlon? Designing a home to meet these requirements was also, in many ways, contradictory to the house’s philosophy. The conceptual driver of the First Light house was the iconic ‘kiwi bach.’ Commonly defined as “something you built yourself, on land you don’t own, out of materials you borrowed or stole,” the bach gives a unique model of comfort and how people might live in a space. Its values are associated with a relationship with the outdoors, a focus on the social aspects of the home and a simple use of technology. As the project developed it was also apparent ‘the bach’, if it were used all year round, could become a symbol for the current state of many New Zealand homes; cold, damp, unhealthy and wasteful of energy. Finding ways to improve this while maintaining the essence of the bach became one of the major motivations throughout the design process. The challenge with this was that the goals associated with designing a ‘kiwi bach’ for a New Zealand climate were, in many ways, conflicting with the requirements of the Solar Decathlon competition. Using comprehensive thermal modelling the First Light house was designed as a net zero energy home that could meet the requirements of two quite unique briefs for two distinctly different climates. Throughout this thesis the often contradictory relationship between the First Light house as a Solar Decathlon entry and the First Light house as an energy efficient ‘kiwi bach’ is explained. Broken into three parts the thesis looks at the passive design of the home and the optimization of the building envelope through thermal modelling, the active side of the design and the generation of solar energy and finally documents the actual performance of the house both in Wellington and in Washington DC during the competition.</p>

<p>This thesis documents a two year journey to design and build a most unconventional kiwi bach. It reports on the applied research undertaken in order to meet the specific requirements of a particular construction project: the development of a transportable, modular, demountable, entirely solar-powered house built in New Zealand to compete in the US Department of Energy’s 2011 Solar Decathlon, held in Washington DC. This challenge was initially taken on by a small team of undergraduate students with very little previous experience in the construction process. The team faced a set of technical and logistical hurdles that would have been daunting for even the most experienced practitioner to negotiate, let alone a group for whom an architectural career was just beginning. Such challenges included: - Creating a house design that would comply with two sets of building codes, endure 18,000 kilometres of transport over two months, expedite assembly by a team of unskilled labourers, and enable comfortable inhabitation after seven days; - Optimising the thermal performance and liveability of one building for two climates in two hemispheres; - Using architecture, landscape and interior design to explain New Zealand and its lifestyle to an American audience of 200,000; - Realising an entire and complex project that required 100% external funding and in-kind support from as-yet unknown parties. By predisposition, then, the project was not going to be simple: very little of the process and very few of the construction details were going to be standard in any way. This thesis focuses on the critical design developments of the house interior, from a hypothetical design to the full-scale assembly of a ‘kiwi bach’ in the heart of Washington DC. The research and outcomes presented here are not necessarily all precedents for future building projects, but rather ‘best-fit’ solutions for the highly particular and constrained design situation brought about by the interaction of the range of logistical, legislative and economic controls, the dynamics of the wider team, and the demands of the Solar Decathlon competition. The project as a whole can, and should, act as a valid precedent for future architectural projects with regard to research into modular construction, prefabrication, and the collaborative building process. The students that were involved will embark on their professional careers with the Solar Decathlon experience as a foundation for their future contribution to the construction industry.</p>

Kaupapa Māori

We describe a collaboration between Māori (Indigenous people of Aotearoa/New Zealand) and Tauiwi (non-Māori) researchers on a software engineering project. Te Tiriti o Waitangi (The Treaty of Waitangi) provides the basis for Māori to lead research that involves Māori as participants or intends to impact Māori outcomes. Through collaboration, an extension of the traditional four-step software design process was created, culminating in a nine-step integrated process that included Kaupapa Māori (Māori ideology) principles. The collaboration experience for both Māori and Tauiwi highlighted areas of misunderstanding within the research context based on differing worldviews and our ability to navigate and work through this. This article provides context, guiding principles, and recommended research processes where Māori and Tauiwi aim to collaborate.

The Subject

In 2018, interviewing Peter Haythornthwaite for a small contribution to the book, ‘Design Generation’1 (by Michael Smythe; published in support of an Objectspace exhibition of the industrial designer’s work), the designer ventured on to the subject of beauty and its importance to his design process. It seems fitting to start here with that idea, because while beauty’s role in design is little discussed today, Haythornthwaite saw how objects of beauty make everyday use a delight.

This article explores the performances and narratives of nature-based tourists, more specifically of trampers, on Stewart Island, a remote tourism destination located in the southern waters of Aotearoa/New Zealand. It does so by reflecting on the concepts of commodification and of spectacle and how these may influence the experiences of tourists on the wild landscapes of Stewart Island. The study used an interpretive and embedded methodology, where the author was able to engage with the experiences of Others while tramping for extended periods of time on the island. This article concludes that the trampers’ experience of nature on Stewart Island is modulated by a media-constructed and media-sold tourism concept that fits well in a cultural and physical landscape that is able to provide an experience associated with a produced ‘nature’. Nature is therefore constructed to allow for an experience that is designed prior to the actual performance.

The University

This paper describes the mechanical systems, the DC-coupled electrical system, the simulation approach and the preliminary results of the University of Illinois entry in the 2007 Department of Energy Solar Decathlon competition. The competition showcased twenty net-zero energy solar powered houses. The University of Illinois entry was the only one that featured an all-electric design. No solar thermal collectors were used; space and water heating was accomplished primarily through heat pumps. Each of three house modules is sensibly conditioned with autonomous, custom mini-split heat pumps using all radiant and natural convection heat exchange for the interior side. Simulation methods are described and assumptions of wall and window properties, mechanical system performance and electrical system performance are disclosed. Details are provided on the theoretical analysis of internal heat transfer and the basic design of the custom mechanical system. The electrical system topology and equipment choices are presented and initial performance results are shown. Additionally, preliminary analysis is carried out on the data taken during the Solar Decathlon competition and on the observations of post-competition winter performance. The success in being awarded comfort conditioning points during the competition is discussed along with drawbacks not represented in the competition results.
