En dehors de la sobriété énergétique qui est beaucoup plus comportementale, la performance des équipements est indispensable pour la réduction des la consommation énergétique d'un hôpital. De ce fait, il est important de remplacer les équipements énergivores par des équipements de bonne performance énergétique. Il s'agit de l'éclairage, des équipements de climatisation et des équipements hospitaliers.

Upgrading equipment involves replacing outdated HVAC systems, lighting, and medical equipment with modern, energy-efficient models. Key actions include transitioning to LED lighting, installing high-efficiency HVAC units with smart controls for optimal temperature and ventilation management, and choosing ENERGY STAR rated medical equipment that consumes less power. These upgrades, while requiring initial investment, significantly lower energy usage and costs, contribute to a more sustainable operation and often improve the overall hospital environment for both patients and staff.

Hospitals ought to integrate HVAC with geothermal energy systems, leveraging the ample free land typically available around their buildings for the geothermal setup. This combined system promises heightened efficiency and minimal energy consumption. Furthermore, supplementing with photovoltaic installations could eliminate emissions and energy bills altogether. While the initial investment may be substantial, the long-term benefits justify the expenditure.

You can also do a lot without upgrading the equipment.1) Every MWh of waste heat and waste cooling can be used for a proxy (or co-located) hydrogen production via electrolysis2) Partner with an innovative green hydrogen producer (such as @Hydrogen Prospect) and sell the waste heat and cooling to hydrogen production to offset hospital equipment inefficiencies3) Use oxygen on-site for hospital needs4) Use hydrogen for backup power and as an additional revenue stream

Measure. Hospitals have to measure individual energy by room every cycle. Whith trusted data its very easy to identify areas of saving comparing room to room. Hospitals can report daily in every floor whats energy consumption in every room, all rooms ( all patients ) no one will be proud to be identified as the energy waste champion for the day. Hospitals have to create a competence of energy savings floor by floor or area by area or department to department to keep everybody hungry for new savings opportunity. solartronik@hotmail.com

Knowledge and awareness of how simple actions like switching lights off etc can go a long way to reducing energy.. and along with data tracking it and measuring the data you should be able to pin point where awareness is required

There are several actions you can take:Turn the heating down 1-2 degrees permanently. Don't let hot water run constantly (plug in the sink and use the water then drain)Turn off machines on standby/sleep mode when not being used.Turn out the lights when you're the last one leaving a room (Have stickers reminding people to do this.)Turn computers fully off at the end of the day (also helps prevent computer virus attacks)Unplug at the wall so machines can't be accidentally turned back onUse LED bulbs in areas where extreme brightness is not a necessity. A concerted effort with stickers to remind people to take the necessary actions can save £000s on the energy bills.

The majority of the energy consumption in hospitals would be electricity in the form of power and heat. At first gain access to the electricity bills from the past 1 year to understand the max and min consumption and plan the solar PV installation accordingly. This would take care of the power need.Have an installation of solar heat pump or solar water heater based on the requirement of hot water and this would be a major reduction in heat energy necessity. Any hospital would also have a major chunk of waste being generated and having a biogas plant can be installed to generate methane and thus produce electricity powering the street lights.

Concernant les projets photovoltaïques, il faut considérer correctement les consommations du bâtiment, déterminer la puissance optimale à installer de panneaux et identifier les programmes de subvention disponibles en fonction de la typologie du projet (étude de faisabilité, étude de structure et investissem*nt).

Joining a green network can significantly aid a hospital in reducing its energy consumption through collaboration, knowledge sharing and accessing resources focused on sustainability. Green networks, such as Healthcare Without Harm or Practice Greenhealth, provide platforms for healthcare facilities to learn from each other’s experiences, share best practices, and leverage collective purchasing power for energy-efficient technologies. Participation in such networks facilitates access to tools, guidelines, and case studies on successful energy reduction strategies, including the use of renewable energy, energy-efficient building design, and operational improvements.

As the saying goes, "An ounce of prevention is worth a pound of cure." Harvard research shows that air pollution from fossil fuels kills 1 out of every 5 people, or 8 million people a year. This pollution can contribute to all sorts of cancer and diseases before death, making *more people sick and in need of care*. That means more people going to hospitals, which increases energy usage a bit, and the need for more hospitals or rooms in general.Hospitals, given their Hippocratic Oath to "first, do no harm", should not only eliminate their own air pollution as quickly as possible, but should use their influence to push society to do the same in whatever ways they can (like influencing local policy for example to eliminate emissions asap).

I'm surprised to not see an option here of dealing with this problem at the source, i.e. encourage healthier lifestyles so that people don't need to go to the hospital as much. A sugar tax and banning advertising of junk food could help in this regard, though I am not an expert on public health policy.

“If you can’t measure it,you can’t manage it “Implement a centralized system like digital twin to monitor and control various building systems like HVAC, lighting, and hot water. This allows for data-driven optimization and real-time adjustments to improve efficiency.Continuously monitor energy consumption across different departments and equipment. This data helps identify areas for further improvement and track the effectiveness of implemented strategies.

The most important think to consider is what the specific objectives are behind any potential energy efficiency projects. Some options may be more expensive than others and would require different cash flow patterns. It may represent additional work to manage energy sell/purchase activities if a market strategy is preferred. The core activity of the hospital should not be jeopardized either, considering potential balckouts
