1 Introduction
It is noted that commercial sector is the most accelerated sector in New Zealand Economy. The value added from this sector in 2014 is about 44% of GDP and the share has doubled from 1990’s ’s GDP (MBIE, 2015). The rapid growth of this sector, indeed, require support from various input factor such as energy. Despite low value, the energy intensity of commercial sector has increased steadily by 1.2 % since 1990.
As part of educational services, The University of Auckland (UoA) has faced the challenge to optimize stakeholder’s productivity by increasing and upgrading facilities and equipment and more extended hours in academic and research activities. One of the key factor in determining energy intensity in the commercial sector …show more content…
Space heating activity utilizes gas as the main fuel and mostly takes place during Summer reaching the peak in July annually (Appendix 3) while cooling require electricity to support the chiller exhausting the heat. There are 2 meters monitoring electricity consumption associated with chiller equipment, namely 1511 and 1514. The later one is dedicated for monitoring electricity consumption for chiller on the data centre. Consider the importance of data centre, it is almost impossible to apply energy efficiency technology in this area. However, load profile of 1514 indicates that most of the electricity consumption (76 percent) occurs outside of normal hours. Energy conservation program should involve all universities stakeholder in changing behaviour of accessing data. Contrast to space heating, energy use for cooling purpose mostly appears during summer and autumn between January and April (Appendix …show more content…
The remaining consumption is dedicated for chillers. Some inefficient behaviour that can be noted is the use of computer other than study and research purpose. This may cause as much as 76 percent of energy load occurred outside normal hours like shown in load profile of data centre (1514) (Appendix 4). This existed also during tests and exams periods. The policy of computer use for students should be re-managed and reinforce more effectively to reduce the load on chillers in the data centre. Apart from that, the chillers facilities require routine maintenance and check-up to maintain or improving performance
In addition, the lighting and excessive of equipment operation appear to take places frequently. For example, most of the times there is unoccupied space with lamp kept turned on and many times more than one printer is kept run in normal mode (not in safe mode) when there are very few people in common computer facilities and labs.
