ENERGY GENERATION
are especially useful for buildings that lack the space to install large-scale heat pump and chiller systems. As with any new technological equipment, there are many complicated configurations that are sometimes difficult to optimise. When you have a very complex building with a complex set of data that needs to be connected and analysed at every level, you need to dig deeper. This is where Artificial intelligence (AI) and Machine Learning (ML) come in.
Model-predictive control Using model-predictive control, AI and ML can take every possible scenario of a building’s dataset to build an understanding of the actual energy conversion rate for each element of the building. This in turn helps us to understand how to run the system as a whole, rather than in siloes. New data that comes in is automatically added as a scenario, and the AI learns from this to create better recommendations for optimisation. It is also able to add in any constraints or anomalies, which means that we can accurately use the data from the platform to preview optimum operating point – thus enabling us to understand what we need to implement into the system to deliver the energy in the most efficient way.
A new way of operating systems The UK and the NHS as a whole need new tactics and approaches to forge a way through and make their operations future-fit. With the drive towards Net Zero in need of urgent acceleration, the way we operate systems is key to reducing energy.
When external temperatures vary so much, ‘wasted’ energy can be reused in a building by integrating both heat pumps and chiller systems.
Introducing heat pumps is a solution for healthcare services to improve efficiencies, drive down costs, and remain on track for carbon neutrality. Yet we must remember that introducing these new systems increases complexity, so we need to move towards better models, deployments, and set points, to achieve better energy efficiency. The good news is we don’t need to
make the switch alone. Tackling challenges, driving down costs, and building improvements into an entire operation, is at its heart an exercise in collaboration. By choosing a reputable partner to work with, hospitals and other healthcare facilities
can implement systems across a whole suite of different buildings with different needs, including hospitals and university campuses. Despite the pain points, we have an urgent prerogative to set a new standard through people, technology, and processes. Let’s make sure we don’t let the potential slip away.
