9 Utah Beehive State 4 day week Involving 17,000 state employees in Utah 4 x 10 hour days better hours of access to services New slogan - TGIT! Thank God it s Thursday 13% reduction in energy use over 12 month period Fridays mid-day hours replaced by cooler times of the day on Monday and Thursday Estimated $6 million petrol cost saving Reduced sick leave, no significant drop in productivity Stimulated growth in small to medium sized businesses - Invisible costs not clearly measured and valued ICLEI Forum - Which way to the future? Strategies, Tools and Inspiration for transforming cities

10 Passive solar is a given yes? Only primitives & barbarians lack knowledge of houses turned to face the Winter sun. Greek playwright Aeschylus ( BC) Energy efficiency/passive solar design must be a complimentary activity High insulation standards, high quality glass and windows, heat recovery systems, and passive solar devices such as shading devices, appropriate distribution of internal thermal mass.. reduces daily variation in temperature Human behaviour factor A zero energy or 6+ star designed house is only as efficient as the people who live in it allow it to be!

28 Urban Planning definition and context for Task 51 Urban planning (urban, city, and town planning) a technical and political process concerned with the control of the use of land and design of the urban environment, including (utilities and) transportation networks, to guide and ensure the orderly development (and renewal) of settlements and communities. It concerns itself with research and analysis, strategic thinking, architecture, urban design, public consultation, policy recommendations, implementation and management. Source: Taylor, Nigel (2007). Urban Planning Theory since 1945, London, Sage Where does solar energy fit in the order of priorities urban planners consider? How is it considered? How well is it considered? What are the needs and knowledge products required to make informed decisions?

44 Summary Understand and engage with all stakeholders Identify the change agents Collaborate to source purposeful and reliable data/tools Tools need to be shaped in partnership with the key practitioners who will use them do not assume you know what they need and that they know what they need! Empower participation through GIS visualisation that is accessible, updatable and inspiring o Market relevant and enabling o Policy impactful scenario based o Drives comparison and healthy competition
