CoSponsor: 2.8 Building Environmental Impacts and Sustainability
Hospitals have traditionally been high energy users. Recent research has shown that hospitals can be designed and operated as 'Net Zero Energy Buildings' or even positive energy, contributing to their local community's low carbon goals, in a cost effective and sustainable manner. This seminar collects reports from European research, UK energy targets and discussion of North American ambitions to reduce toward zero. Cost effective technologies exist but need to be adopted and applied in new and existing facilities to achieve NZEB in this challenging sector. Support such as a new ASHRAE design guide on NZE Hospitals is discussed.
1 Toward NZE Hospitals in North America
North American hospitals are high energy users due to their intense usage and environmental control required for healthcare. However there are techniques which could be applied to existing and new hospitals to achieve net zero energy usage based on a low energy and efficiency approach complemented by renewable energy systems. This presentation considers what steps need to be taken to reach NZE outcomes and highlights potential risks and concerns which are peculiar to hospital buildings.
2 Owner Perspective on Potential for NZE Healthcare Facilities
This presentation discusses the owner's perspective for potential of NZE in US hospitals at national scale. It discusses ideas from the US market contrasted to international viewpoints. How does the US perspective vary from the international perspectus? What do we need to be looking at to move the national portfolio to NZE? What are the biggest uses and how do we address them cost effectively? What is the cost and economic viability of NZE deployments and conversions? What synergies do NZE have with resilience that can make the economics more viable or feasible?
3 European Research Study into NZE Hospitals
This presentation addresses the project “nZEB Hospital Buildings” undertaken in cooperation with the Eindhoven University of Technology and supported by TVVL and REHVA to give information and insight in nZEB developments that will occur in the near future and what the consequences of these developments are for hospital buildings and in particular for building services. Hospitals consume approximately 1% of the primary energy in the Built Environment. Majority of energy is used by the building and building services. The study considers future scenarios of required building performances, functions/usage of the buildings, technological innovations and business case parameters.
4 Strategies for NZE Hospitals in the UK
The UK has committed to low carbon targets, 80% total reduction by 2050. This will require buildings including hospitals to become "Net Zero" and even positive contributors toward this target. Research has shown that massive reductions are possible and that with the appropriate strategies there can be cost benefits which would help to ease the financial pressures on the NHS. By embracing low carbon energy as a resource and of value to the community, hospitals could start to see an income stream from their waste energy.
