The aim of the proposed research framework is to bring together and develop the evidence that is required to form policy related to agreeing and achieving a long-term stabilisation goal. This includes scientific and economic evidence related to the following work packages: 1. Impacts of climate change 2. Emissions pathways and concentrations of greenhouse gasses 3. Policy options and technological measures 4. Long term targets 5. Behavioural perspectives on climate change The work packages are broadly related as shown in the figure: emissions pathways (WP2) How would GHG emissions have to change now and in the future to achieve different stabilisation levels? policy options and Impacts (WP1) technological measures (WP3) How does stabilisation level How can target levels be achieved and at affect the climate and human what cost? welfare? long term targets (WP4) At what level should targets be set to achieve the optimal balance between costs of mitigation and the risks of climate change? behavioural perspectives (WP5) How will individual and institutional beliefs and valuations help or hinder efforts to achieve targets? Risk Solutions supported by an expert panel was appointed to scope the proposed research framework. The expert panel is drawn from a number of institutions renowned for research in climate change including the Met Office Hadley Centre, the University of Cambridge, the University of Cardiff and the University of Leeds (see further details in Section 2 of these appendices). Scoping the research programmes required identifying where the critical research gaps are relevant to Defra’s need and developing these into possible research work packages. To understand where key uncertainties and gaps in the research lie we interviewed policy and research stakeholders, reviewed key secondary literature, ran a workshop of researchers to review and develop findings further and also held a separate meeting on economics issues. 1 TASGC Scoping Study - Appendices Issue 1 The key results and conclusions are presented in the main report. In the appendices (this report) we have summarised the information we have gathered under each work package. The appendices therefore provide a statement of our understanding of the gaps and uncertainties. Section 2 lists the main publications included in the review, the expert panel, and the policy makers and researchers interviewed. Sections 3 - 7 presents the results for each work package area. Section 8 presents a bibliography of useful references relating to each work package area. We have included in this report references to the source of information to provide an audit trail. P references refer to points raised in policy interviews and R references to points raised in Researcher interviews or by the experts on the project expert panel who reviewed the appendices. Points raised have not been attributed in this report to individual interviewees, the P and R numbers do not correspond to the order in the tables in Appendix 2. The references to documents do refer to the numbered references given in the table in Appendix 2. 2 TASGC Scoping Study - Appendices Issue 1 2 CONSULTEES AND REFERENCES Name Organisation Policy consultees Molly Anderson Environment Agency Keith Brierley Environment Agency Adrian Butt Defra David Curran BERR Ben Day HMT Chris Dodwell Defra James Dyer Defra Paul Gilham Defra Nick Grout Government Office for Science, supporting the CSA Claire Hawley Defra Graham Floater Stern team Aditi Maheshwari DfID Jeremy Martin Defra Brian Morris BERR Steven Muirs Office of Climate Change Frances Raynor FCO Hannah Ryder Defra Chris Sear Defra Chris Taylor DfID David Warrilow Defra Bob Watson Defra Roger Worth Dept. of Transport Researcher consultees Prof Neil Adger University of East Anglia / Tyndall Nigel Arnell Walker Institute Dr Richard Betts Met Office Hadley Centre Dr Tom Downing Stockholm Environment Institute, Oxford Centre Dr Michel van Elzen MNP Netherlands Prof Michael Grubb Carbon Trust and Imperial College Debbie Hemming CEOSA Defra and Met Office Hadley Centre Prof Sir Brian Hoskins Grantham Institute and Chairman Met Office SAC Prof Tim Jickells University of East Anglia Diana Liverman Environmental Change Institute, Oxford Karsten Neuhoff Faculty of Economics, University of Cambridge Vicky Pope Met Office Hadley Centre Colin Prentice QUEST Dr David Reay University of Edinburgh Dr Gavin Schmidt NASA / Goddard Institute for Space Studies Dr Emma Tompkins University of Leeds Dr Rachel Warren Tyndall Centre Chris West UK Climate Impacts Programme Dr Detlef van Vuuren MNP Netherlands 3 TASGC Scoping Study - Appendices Issue 1 Workshop attendees (7 March 2008) Name Organisation Syndicate Olivier Boucher Met Office WP 3 & 4 David Frame University of Oxford WP 3 & 4 Joanna House Bristol University WP 3 & 4 Chris Huntingford CEH Wallingford WP 1 & 2 Tim Jickells University of East Anglia WP 1 & 2 James Kopka Defra CCE WP 3 & 4 Jason Lowe Met Office Hadley Centre WP 1 & 2 Kathy Maskell Walker Institute WP 5 Maria Noguer Walker Institute WP 1 & 2 Jean Palutikof IPCC WP 1 & 2 Nick Pidgeon Cardiff University WP 5 Alexa Spence Cardiff University WP 5 Debbie Hemming Defra CEOSA WP 5 Chris Sear Defra CEOSA WP 3 & 4 Jo Thorpe Defra CEOSA WP 1 & 2 Tony Quigley Independent for Risk Solutions All Ian Dunbar Risk Solutions WP 1 & 2 Richard Wheldon Risk Solutions WP 5 Helen Wilkinson Risk Solutions WP 3 & 4 WP3/4 Economists meeting attendees (18 March 2008) Name Organisation Hannah Ryder ICC/CCE, Defra James Kopka ICC/CCE, Defra Jim Penman CEOSA, Defra Stephen Prichard OCC, Defra Helen Wilkinson Risk Solutions Project expert panel Name Organisation Prof Piers Forster University of Leeds Dr Jean Palutikof IPCC WG II / Met Office Dr Jason Lowe Met Office Hadley Centre Dr Terry Barker University of Cambridge Prof Nick Pidgeon Cardiff University Dr Alexa Spence Cardiff University Tony Quigley Independent 4 TASGC Scoping Study - Appendices Issue 1 The following references were used as the initial source of information on gaps and uncertainties in the research.

  • Building Performance Analysis Considering Climate Change
    Building performance analysis considering climate change Yiyu Chen1, Karen Kensek1, Joon-Ho Choi1, Marc Schiler1 1University of Southern California, Los Angeles, CA ABSTRACT: Climate change will significantly influence building performance in the future both through differences in energy consumption (perhaps drastically in certain climate zones) and by changing the thermal level of comfort that occupants experience. A building that meets the current energy consumption standard has the potential to become energy inefficient in the future, and well-meaning designers might be applying passive strategies for current conditions without understanding what impact their choices have under different climate change scenarios for their location. By analyzing a case study building’s thermal performance, specifically lifecycle energy use, for multiple climate change scenarios and in different climate zones, it is possible to inspect the resilience of passive design strategies over time. Varying the solar heat gain coefficient (SGHC) was the first strategy tested. To estimate the building’s future performance, three projected future climate conditions were created (for low, moderate, and severe climate change) in three climate zones for three different time periods (2020s, 2050s, and 2080s). The first step was to create new projected weather files. They were calculated from a world climate change weather file generation tool that was developed at the University of Southampton. Then the weather files were used in EnergyPlus to determine the energy consumption. Aggregated multiple runs provided lifecycle energy use for each of the three locations. Then the SHGC values were varied to determine which initial values provided the best long- term result. Although currently only SHGC was tested, this research provides a methodology for architects and engineers during the early stage of design that they can use to avoid the detrimental consequences that might be caused by climate change over the lifecycle of the building.

  • Energy Systems Modeling for Twenty-First Century Energy Challenges
    Energy systems modeling for twenty-first century energy challenges Stefan Pfenninger1,* Adam Hawkes2 James Keirstead1 8 January 2014 (author version of accepted paper) * Corresponding author: [email protected]. 1 Department of Civil and Environmental Engineering, Imperial College London 2 Centre for Environmental Policy, Imperial College London Published version: Renewable and Sustainable Energy Reviews, 33, pp. 74-86. DOI: 10.1016/j.rser.2014.02.003 Abstract Energy systems models are important methods used to generate a range of insight and analysis on the supply and demand of energy. Developed over the second half of the twentieth century, they are now seeing increased relevance in the face of stringent climate policy, energy security and economic development concerns, and increasing challenges due to the changing nature of the twenty-first century energy system. In this paper, we look particularly at models relevant to national and international energy policy, grouping them into four categories: energy systems optimization models, energy systems simulation models, power systems and electricity market models, and qualitative and mixed-methods scenarios. We examine four challenges they face and the efforts being taken to address them: (1) resolving time and space, (2) balancing uncertainty and transparency, (3) addressing the growing complexity of the energy system, and (4) integrating human behavior and social risks and opportunities. In discussing these challenges, we present possible avenues for future research and make recommendations to ensure the continued relevance for energy systems models as important sources of information for policy-making. Keywords: energy systems modeling; energy policy 1 Introduction Hamming (1962) argued that the purpose of computing is insight, not numbers.

  • Cooling Energy Implications of Occupant Factor in Buildings Under Climate Change
    sustainability Article Cooling Energy Implications of Occupant Factor in Buildings under Climate Change Ji Hyun Lim and Geun Young Yun * ID Department of Architectural Engineering, Kyung Hee University, Gyeonggi-do 17104, Korea; [email protected] * Correspondence: [email protected]; Tel.: +82-31-201-3859 Received: 24 October 2017; Accepted: 6 November 2017; Published: 7 November 2017 Abstract: Occupant factor is a critical element in the overall energy consumption of buildings. This study aims to reveal how occupant factors influence the energy consumption of example buildings in Seoul, Tokyo, and Hong Kong under climate change projections, and to prioritize factors with energy saving potential for buildings in consideration of future climate change. The study finds that the cooling degree-hours base of 23.3 ◦C in the three cities sharply increases with future climate change by analyzing future hourly weather data produced herein. Simulations are made with EnergyPlus Runtime Language (Erl) for modeling occupant behavior. The simulation results reveal that a dynamic thermostat control based on an adaptive comfort model is an effective method to reduce cooling energy consumption under future climate change, reducing cooling energy consumption by up to 18% in some instances. In particular, we reveal that a combined application of the adaptive comfort control, nighttime ventilation, and the use of occupancy-based lighting and equipment result in reducing cooling energy consumption by 28%. The outcomes of this study are potentially useful in providing cost-effective solutions to adapt buildings for future climate change with simple modifications to occupant behavior. Also, the roles of renewable energy are briefly discussed.
