Climate Change Impacts

Lack of resilience

High energy bills

Summer overheating

Customer discomfort 9.06OC

Adaptation vs Mitigation and Retrofit

Mitigation AdaptationReduce energy use Increased summer temperatures

Reduce water use Increased flood risk

Lower carbon footprint More extreme weather events

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

Bruntwood– Adaptation and Mitigation

Three packages

1. Behavioural

2. Fabric

3. Services

Two categories

1. Suite related (impact on customers’ electricity bills)

2. Building related (impact on service charge energy costs)

Cost-benefit Analysis

Page 8: Adapting the city. Building & Infrastructure Dr Tim Whitley Associate Director, Arup.

Key Intervention examples

Envelope and environmental system strategyHigh performance glazing

Solar shading through glazing and blinds

Insulation to roof and spandrel panels

Expose soffits for passive/night time cooling

Install high efficiency ventilation and conditioning systems

Maximise daylight opportunities

Key Intervention examples

Control & monitoring systemsEnhanced BMS, increased controls, smaller zones

Lighting control zones, low energy lighting

Extensive sub-metering and real time displays

Comprehensive behaviour change strategyPrompt energy conscious behaviour change
