Achieving PFI Energy Targets
Customer: A medium-sized acute
hospital, east of London
Focus: Onsite review to enable better performance against PFI energy consumption targets
The Challenge: An acute hospital east of London needed to address its poor
performance against contractual PFI energy performance targets.
Actions: Concept undertook a thorough site survey, paying close attention to the main heating and steam boilers, chillers, plant rooms and ventilation units. The assessment was based on energy data provided from meter readings, supplier invoices and half hourly electricity data.
The survey set out to review actual performance against PFI energy targets, the impact of weather on energy and performance, areas of excessive energy consumption and detailed recommendations for performance improvement.
Outcomes: Achieving PFI targets: When Concept checked the metering on site, it became apparent that there was an anomaly in the meter reading/reporting process and in fact electricity consumption had been over-stated. Using revised consumption figures
for electricity, the site performance against target is significantly improved; in fact it is below the 59.44GJ/100m3 target threshold.
Energy savings of 10% identified: The building was performing well against published benchmarks. Yet Concept was still able to reveal a range of worthwhile opportunities for energy reduction. Estimated savings of £136,970 were identified and recommended to the client, equating to 781 tCO2 savings and a reduction in costs of 10%. Concept estimates that investment in these measures would pay for itself in under 2.5 years.
