The Estates Gazette has this week reported on the approach that British Land have taken in an effort to reduce their carbon footprint, initially on their head office building (York House in London) but eventually across their entire portfolio.
Their approach appears quite ‘basic’ on first inspection. They are aware that their portfolio is ‘what it is’ and that they have to work out savings utilising the current fabric of their buildings. So what have they done and what effect has it had on carbon and more importantly costs?
Well, York House is a 90,000 sq ft building in the centre of London (of which BL occupies 40,000 sq ft, the remainder being let to four other tenants). In total it has 365 occupants, so is a good test of what can be done on a large office building.
In the 12 months to March 2010 BL saved 1,098,995 kWh and therefore emitted 416 tonnes less carbon than in the previous year. This sounds impressive, but it’s the financial saving that also needs considering (and makes more sense to both Landlord and Tenant).
Over the 12 months the following savings were seen;
£51,834 saving in heating and cooling bills – that’s a 32% cut!
£11,000 saving in lighting bills.
And how was this achieved?
Basically a new state of the art energy management system was installed, alterations made to thermostats and lots of bulbs were replaced. The cost – £65,000, just £2000 more than the first years saving! That is a very impressive pay back period!
BL have confirmed that these savings are being passed straight to the tenants, so arguably making the building more attractive to the market and more easily let (although this effect has yet to be seen in reality in the market). The systems installed do need constant monitoring to ensure the maximum savings are returned, but this is a small price to pay for such a saving and is potentially easy via modern IT.
Without doubt this is the type of action that all landlords and managing agents should be looking at for their portfolios. It would appear to me that all sides win, and the carbon footprint of the building is improved (possibly important in the future if EPC’s are linked to rating for example). BL are now going to roll this approach out across its portfolio – good for them (and their tenants).
I know that this type of approach could benefit my organisation. We have 3 offices and I am sure that this aspect of our occupation has not been considered in this way. Perhaps some expenditure on better control of heating, cooling and lighting could show a good level of saving – and not over as long a payback period as currently thought?
At a time when we are all looking to save money (and waiting for the Government to tell us how it is going to save six Billion pounds next year) this approach has to make sense! New buildings have to be ‘green’ to comply with current building regulations – it is the existing stock that needs to be addressed as that makes up the majority of the UK property stock.
