Gardner & Co was praised for the use of its air handling units in converting a 27,800 sq m distribution
warehouse in a data centre cooled with close to 100 per cent outside air.
Eight 2.2 m diameter variable speed axial fans each housed in their own acoustic closure were installed in each hall to be used to supply air, with another eight used for exhaust air without an enclosure, in an N+2 arrangement - making 64 in total.
The result was an anticipated annual energy saving of 40 per cent compared to a typical mega data centre design, along with a power usage effectiveness rating of 1.16 - the current best practice being 1.5 for a data centre.
Judges were impressed with this result, as traditional data centres use several thousand megawatt hours per year and typically 60 to 70 per cent of that is used for the facilities power and cooling systems.
The installation period was carried out over six months, with the system design still being tweaked as Gardner & Co says that nothing like this has been accomplished before.
The company added that this type of system had no industry standard commissioning processes, so new ways of commissioning the systems had to be established.
Judges said of Gardner & Co: “This company is leading the way in helping UK businesses become more energy efficient.”
“A lot of companies are claiming environmental credentials, but to win this award adds a great amount of credibility”
