The Carbon Trust have completed a report that shows the measures made by the team at the National Space Centre to drastically cut down on wasted energy have not only been a success but have also made a significant difference to cutting pollution. 

It was calculated that the energy use, including gas, has fallen from 4.2MW hrs / annum (2005) to 2.1MW hrs / annum (2010) which is an enormous saving and far greater than the trust had seen to date and will save over 500 tonnes of carbon from polluting our planet.

Saving each day the equivalent of a years worth or energy for a standard sized house!

The changes have been made to the home of the charitable trust by:

• Better/more flexible time clock zones added to BMS areas

• Developed intelligent algorithms to control new invertor drive based on heating/cooling demands

• Reducing capability of plant by running less AHU’s in common areas when conditions allow

• Using flexible set points bands based on external conditions

• Using fresh air as a cooling source when conditions allow as opposed to close circuit air conditioned air as originally designed.

• Inhibiting dehumidification where possible.

• Reduced boiler set point temperature

• Adding invertor speed controlled capability on one pump of each of the larger pump sets & AHU fans

• Added time clock to hot water circulation pump

• Including any new split AC units are controlled by the BMS time zone strategies.

• External lighting zoned and individually controlled on twilight detection & time

• External tank (building) lights reduced by 75%

• Most hot lamps in exhibition removed or replaced with energy saving equivalents where practical

• New exhibition refresh work uses LED or CDM technology where possible

• New DLP projection system in planetarium now provides cove lighting as opposed to ring of hot incandescent lamps as previously used.
