    The Environmental Impact of the Waitakere NOW Home®: A Life Cycle Assessment Case Study (PDF 2MB)

    Nick Collins, Andrea Blackmore

     

    A Life Cycle Assessment case study of Beacon Pathway's Waitakere NOW Home® indicates that the greatest environmental impact of a house is not during construction or manufacturing, but from its operation over the life of the house.  The study focused on the house itself over a 100-year period in New Zealand, with a family of four inhabiting it. Heating, lighting and hot water were considered, and seven key building systems were evaluated separately.  Life cycle phases of construction, use, maintenance, transportation of materials to site and end of life were included.  New Zealand-specific Life Cycle Inventory data was used, wherever possible, for building materials.  However, where New Zealand data was unavailable, European industry data was used.

    Integrated Water Management Design Criteria Report (PDF 354KB)

    David Kettle

    This project developed a product design criteria methodology to assess water saving products and systems to identify potential commercial opportunities.  The best overall 'score' came from a combined 'system', comprising a low flow shower head, a water efficient washing machine, a 9,000 litre rain water tank and greywater reuse.Two potential commercial opportunities were identified; the installation of a relatively small 200 litre rainwater tank attached to the side of the house to supply toilet water only; and a 'modular' tank system where small storage blocks of 200 to 300 litres each could be connected up in irregular shapes to fit under decks, etc.

    LCA-based Window Calculator (Excel calculator) (Excel spreadsheet 664KB)

    Daniel Kellenberger, Nicolas Perez

    This research developed a working prototype of a tool to using life cycle assessment to quantify the sustainability of a a defined window  with a certain thermal resistance over a lifespan of 50 years. An Excel-based calculator offers a simple interface for the user to define a specific window. Based on this information, the calculator gives the environmental impact of the window over a specific lifespan, as well as the resulting R-value.  This work was not developed further as Beacon's focus moved toward understanding whole-of-house dynamics.

    Prioritisation of Building Systems (PDF 327KB)

    Barbara Nebel, Karen Bayne, Connie Crookshanks

    This reports on the steps taken to select two priority systems for further research: windows for retrofit projects; and walls for new build projects. These two systems were selected from a prioritised list of residential building systems obtained through a series of workshops and project team discussion meetings.  This work was the first step of the systems work.

    Life Cycle Assessment of the Waitakere NOW Home® and two Papakowhai Renovation homes (PDF 580KB)

    David Drysdale, Julie Sandilands

    This report provides an assessment of the environmental impacts of the Waitakere NOW Home® and two Papakowhai Renovation homes using Life Cycle Assessment (LCA). This study used largely overseas datasets, and an analysis of the Waitakere NOW Home® was repeated with as much New Zealand data as possible.  See SM3570/9 The Environmental Impact of the Waitakere NOW Home®: A Life Cycle Assessment Case Study.

    Design Criteria for Retrofit Windows and New Walls (PDF 2.6MB)

    Karen Bayne, Timothy Allan, Kylie Baker

    This report suggests an approach for establishing design criteria for solutions to improve house systems. Product development techniques such as Quality Function Deployment and Product System Assessment were used to identify and prioritise key technical requirements for exterior walls for new homes and windows for existing homes.  Beacon's focus subsequently changed away from product development to addressing whole-of-house dynamics.

    Thermal Insulation in New Zealand Homes: A Status Report (PDF 504KB)

    Ian McChesney, Ian Cox-Smith, Lynda Amitrano

    This paper considers thermal insulation for New Zealand homes, covering technical aspects of new build and retrofit insulation. The policy focus is mainly on the incentives and other means to encourage retrofit insulation, and includes a review of policies in the UK. The paper includes suggestions for improving insulation practice might be achieved.

    Retrofit Technologies Database (PDF 303KB)

    Barbara Nebel, Roman Jaques, Michael Jack, Karen Bayne, Per Nielsen, Susan Krumdieck

    Developed database of technologies suitable for retrofitting existing homes, ranked by potential.  The original aim was to develop a  THEN Home as an exemplar of retrofit.  However, Beacon's focus moved away from individual technologies to understanding whole of house dynamics, and to a refined set of priorities.  This works was not taken any further.

    The Role of LCA in Decision Making in the Context of Sustainable Development (PDF 251KB)

    Barbara Nebel

    This paper gives examples on how the results from Life Cycle Assessment (LCA) studies and the process of conducting the study can assist in decision making processes. Emphasis is on explaining and guidance on interpretation of the information delivered by an LCA as an essential part of achieving broader goals such as sustainability rather than the simple comparison of products. Gives examples of companies who have already successfully implemented LCA in their organisations. The paper concludes with recommendations about using LCA more effectively in decision making processes in the built environment in New Zealand.

    Guidelines for LCA Practitioners and Users of Building Related LCA Studies (PDF 173KB)

    Barbara Nebel

    Life cycle assessment (LCA) is a tool to analyse the environmental impacts of building materials and buildings. The ISO framework provides an appropriate basis for LCA studies. This paper assists LCA practitioners to implement the ISO framework in relation to building related LCAs, and enables users of LCA results to assess the quality and relevance of existing LCA studies.

    Analysis of Currently Available Environmental Profiles of Building Products (PDF 133KB)

    Barbara Nebel, Zsuzsa Szalay

    Summarises New Zealand building-related LCA studies and describes the most relevant overseas databases to analyse the applicability of international data to New Zealand situations.The comparison of embodied energy and results for CO2 emissions showed that New Zealand data differ significantly from overseas data. New Zealand data limited to energy use and CO2 emissions for most building products. Identifies the main building materials where further LCA work is of special importance.
