This building is remarkable by any standards and it demonstrates how technology and innovation can deliver sustainability and unforeseen benefits. This building is so well designed and insulated that it is self sufficient in its energy use and due to vast solar panels on the roof it even generates a surplus of electricity!

The benefits to Tenants are clear, reduced outgoings (including water as the building collects rainwater to use in the ablutions), reduced enviromental impact, carbon footprint and improved green credentials. To top it off, Tenants may be able to sell the excess electricity they generate and supply back into the general network. 

It is also foreseeable that governments will start penalising occupiers for having large carbon footprints given the substantial reductions in emmissions various governments have promised. Indeed the MEES Regulations, albeit they are aimed at the Landlords not the occupiers, may well be a sign of things to come.

But there could also be benefits for Landlords. What if rental valuations or reviews change so that if the Tenant is able to make money by putting electricity back into the general supply that the rental value increases? How will that play out in existing leases? Typically rent review clauses disregard Tenant improvements if they increase the rent. Could this also mean that in certain places traditional "shed" industrial buildings could demand higher rents if the technology to install solar panels becomes more accessable and afforable for Tenants or Landlords? 

Food for thought.
