Acclaim for best campaign, but building shortcomings are revealed

The award for the best carbon-saving campaign was won by United Business Media for its campaign to reduce carbon emissions at Ludgate House in London. The campaign saved 99 t of carbon dioxide.
United Business Media mounted a good carbon-saving campaign at Ludgate House in London, but it is clear that there is far to go.The campaign by United Business Media to reduce carbon emissions at Ludgate House in central London reduced overall energy consumption by 231 340 kWh, based on actual meter readings by the utility companies for electricity and gas. Since the campaign extended over a quarter plus 12 days into September, the consumption for that period was estimated from previous consumption. The resulting carbon-dioxide saving during the 100 days was just over 99 t — an amount that would fill Ludgate House. The saving in electricity consumption was 144 020 kWh, with a further saving in gas of 87 320 kWh. The total saving was 231 340 kWh, a reduction of 2.2%. Best campaign The achievement of UBM was acknowledged with the company being declared the winner of the best carbon-saving campaign. UBM was aided in its campaign by facilities-management provider ISS Coflex. UBM maintained a visible presence, with posters, displays, staff suggestion schemes and themed days populating the reception of Ludgate House throughout the 100 days. Warnings on the consequence of climate change, consumption figures and targets emphasised the serious side of the campaign. On a lighter note, careless staff members were made to pay for their energy wastage by performing an ‘I love the planet’ dance. In The Simplified Building Energy Assessment that was carried out by ISS Coflex, Ludgate House is described as being a standard air-conditioned office. It has a net lettable floor area of 16 253 m2 and a total floor area of 22 574 m2. The SBEM assessment carried out at the end of the 100 days shows that Ludgate House falls far short of being a energy-efficient building. Its electricity consumption was 77% worse than a typical building of this type, but its gas consumption was 23% better. Catalyst Overall, Ludgate House has 49% higher carbon emissions than a typical building of its kind. That is reflected in its energy costs being 52% higher than a typical building. CIBSE’s 100-days campaign has clearly acted as the catalyst for the analysis that has revealed major opportunities for reducing the energy consumption of Ludgate House. There must be many other buildings around the UK than can benefit from a similar analysis.

Can I use my Air Conditioning system?

If your system hasn't been used in months it's an important question. 

New air-cooling system from Weiss Technik has unique four-stage safety concept and innovative thermal disinfection

The Coronavirus outbreak has increased awareness of hygienic room climate issues, ventilation and air-conditioning systems in public buildings. If planned poorly or not serviced properly, air conditioning units can quickly turn into transmitters of disease-causing germs.
