Healthcare systems worldwide have been crippled by the Covid-19 pandemic.
Across the industry there are increased emergency room wait times, a growing backlog of deferred surgeries and treatment procedures, and the upkeep of complex medical equipment contribute to rising operating costs.
This has left players in the healthcare sector with little time to address sustainability challenges, including energy consumption and carbon footprint. With a typical hospital using 61 to 79% of energy on lighting, heating and hot water (Source Stanford University), and an estimated 20% of energy wasted(Source BRE Group) due to inefficiencies, even a marginal improvement could generate substantial savings.
Identify and implement optimal control settings that optimise energy efficiency and reduce carbon, saving up to 15% on energy costs.
Improve your energy mix by maximising the contribution from renewable energy sources like on-site solar and wind installations.
Factor peak electricity tariffs into planned operations to lower grid demand during peak time and reduce running costs.
Foresight Sustainability Suite provides a suite of ready-to-deploy features and algorithms that integrate with existing building energy management systems (including hospital energy sources such as boilers, combined heat and power (CHP) engines, and grid demand) to recommend and implement optimal control settings helping reduce waste, minimise carbon and maximise throughput and quality.
Energy Efficiency Index (EEI)
See opportunities to reduce energy consumption and costs in real-time – no need to spend hours analysing time-series energy usage data, patient count and temperature and humidity. The EEI algorithm recommends power, temperature and humidity settings based on real-time patient count, resulting in quantified energy cost savings and reduced carbon emissions.
Energy Mix Optimisation
Reduce emissions and lower running costs, using location-specific weather forecast data to accurately predict energy generation from on-site solar or wind distributed energy sources.
Digital Health Record
Continuously monitor and benchmark asset performance, detect anomalies and set configurable alerts to be notified about potential risks.
The Queen Elizabeth Hospital Kings Lynn NHS Trust uses Foresight® Sustainability to drive energy efficiency improvements for its boilers and CHP engines, increase renewable energy from on-site wind, and reduce carbon across its 488 beds and a 40,500 m2 space.
Using data on energy consumption from CHP engines, HVAC units and the building management system, as well as hourly patient counts by unit and humidity and temperature sensor settings, the Energy Efficiency Indexwas used to recommend CHP controls and incremental ambient settings changes to optimise energy efficiency. Combining these recommendations with the Hybrid Energy Mix Optimisation to maximise wind turbine contribution to overall site load, the solution reduced hospital annual energy costs by 5% and demonstrated a carbon emissions reduction of 180 tonnes.
