EXECUTIVE SUMMARY

This document records the results of an energy review, undertaken in Q3 2017, of the

operations at University College Cork (UCC). The scope was to review the electrical and

natural gas users and to determine the significant energy users (SEU’s), identify the variables

and people that impact them, identify areas for maintaining and improving energy

performance. The results were obtained from metering information available on the site

metering package and the available billing data. From the review the site SEU’s were

determined based on:

The amount of energy they use.

And / or

The ability to reduce the energy consumption through the register of energy saving

opportunities.

The approach to energy management for 2016/17 focussed on housekeeping measures and

engaging with the SEU’s through the saver saves scheme, where applicable, to understand

how the buildings are used by the departments.

The objective for 2016/17 was to maintain the existing consumption levels for UCC, despite

the planned increases in occupied space, namely the Western Gateway and Food Science

Building. Through ongoing investment, monitoring and engagement with the SEU’s, UCC

achieved a 0.6% decrease in electrical energy and a 8.5% decrease in natural gas

consumption.

16 electrical energy saving projects were completed in 2016/17 and resulted in savings of

440,000 kWh/year. (See appendix III for details).

8 out of 13 electrical SEU’s reported a drop in annual consumption levels totalling 0.6

GWh/year while the remaining 5 SEU’s saw a total increase of 0.3 GWh/year, with the WGB

alone accounting for an increase of 0.16 GWh/year.

Natural gas reduction is mainly attributable to the reduced operating hours of the CHP’s

(discussed further in appendix II) as well as slight savings in other SEU’s.

10 natural gas energy saving projects were completed in 2016/17 and resulted in savings of

55,000 kWh/year. (See appendix III for details).

CAUL are excluded from the scope of this review as well as Tyndall National Institute and the

Mardyke Arena as both areas operate their own independent ISO50001 process.

The objective for 2017/18 is to expand the saver saves scheme, using the Boole Library as the

template and to reduce the existing consumption levels for UCC, despite the planned

increases in occupied space, namely the Western Gateway and Food Science Building.

Based on this energy review and the action plan, the predicted Oct 2017 to Sept 2018

consumption levels are:

19,520,000 kWh of electrical energy and 17,650,000 kWh of natural gas.

The 2017/18 SEU’s and the appropriate EnPI’s for electrical and gas consumption are detailed

in the tables below.
