2 Content Definition of sustainability and resilience Industry guidelines in sustainability and resilience Lessons learned from recent natural disasters Examples of sustainability and resilience in different physical scales: Community (microgrid, energy master planning) Campus (energy master planning and assessment) Building (energy assessment and mechanical design) Equipment (mechanical design and commissioning/retro-commissioning) Q&A

3 Sustainability Sustainability meets the needs of the present without compromising the ability of future generations to be able to meet their needs. defined by UN Committee of the Environment and Development in providing for the needs of the present without detracting from the ability to fulfill the needs of the future defined in ASHRAE Green Guide Similar to that developed by UN. the concept of maximizing the effectiveness of resource use while minimizing the impact of that use on the environment defined in ASHRAE s Sustainability Roadmap by Presidential Ad Hoc Committee An environment in which and equilibrium exists between human society and stable ecosystems defined in The ASHRAE Promise: A Sustainable Future by Terry Townsend ( ASHRAE President).

4 Resilience the capacity to endure. the ability to prepare and plan for, absorb, recover from, and more successfully adapt to adverse events defined by America s design and construction industry drawing upon the work of National Research Council. A common definition of resilience is the capacity to adapt to changing conditions and to maintain or regain functionality and vitality in the face of stress or disturbance. by Nall D. H ASHRAE Journal. Key components: A livable condition or acceptable functionality is to be maintained or adapted to. The event can be natural or human-induced disasters. (hurricanes vs 911/cyber-attack) The event can be long term trends or sudden catastrophe. (climate change vs hurricanes) The impacts of the event can be a short or extended period. (power outage vs 80% PR - 2 mon Maria) Resilience is not Redundancy: Redundancy: refers duplication of critical components or functions of a system to increase system reliability. (N+1) Resilience: widens the scope; it refers to the ability to plan for a natural or man-made hazardous event, absorb or avoid damage, and deliver optimal recovery.
