TRANSCRIPT

  • Adapting the city

  • Building & Infrastructure

  • Sustainable Building RetrofitAdaptation and Mitigation

  • Climate Change ImpactsLack of resilienceHigh energy billsSummer overheatingCustomer discomfort

  • Adaptation vs Mitigation and RetrofitMitigationAdaptationReduce energy useIncreased summer temperaturesReduce water useIncreased flood riskLower carbon footprintMore extreme weather events

    ChallengePotential increased cooling to cope with increased summer temperatures vs reducing energy use

  • Bruntwood Adaptation and MitigationThree packagesBehaviouralFabricServicesTwo categoriesSuite related (impact on customers electricity bills)Building related (impact on service charge energy costs)

  • Cost-benefit Analysis

  • Key Intervention examplesEnvelope and environmental system strategyHigh performance glazingSolar shading through glazing and blindsInsulation to roof and spandrel panelsExpose soffits for passive/night time coolingInstall high efficiency ventilation and conditioning systemsMaximise daylight opportunities
