Stroma Tech commits to London’s Zero Carbon standard

Utilisation of Combined Heat and Power (CHP) requires technical appraisal to ensure that it is integrated to a scheme where it is shown to be a viable solution. Adequate care must be taken to ensure that CHP units are not incorporated to schemes for the sake of ticking a box when their operation does not fulfil the requirements to achieve savings. We would always advocate seeking advice from a CHP specialist at the earliest opportunity where an opportunity may exist.

 

The third rung on the ladder relates to renewable technology. These should be appropriate to the building and complement all other systems. Although Part L assessment methodology compliance is important, it is vital that the building functions efficiently in the real-world!

 

Carbon offset payments

The aforementioned balance between value and cost was defined at the point where CO2 savings were more cost-effective elsewhere. The carbon offset payment is made to the borough during the development and calculated from the quantity of CO2 (regulated tonnes) for a period of 30 years. The Housing SPG refers to an indicative rate of £60 per tonne for 30 years, payable to each borough. Each London borough is tasked with appraising this figure and establishing their spending infrastructure. Based upon specific research by individual councils, the rate currently varies from £46/tonne to £104/tonne, with the borough of Islington requesting a one-off payment of £920 per tonne. Therefore, early investigations are critical to ensure an accurate cost estimate is known whilst developing the energy strategy.

 

Variation in carbon offset prices is largely due to a lapse in research for borough specific operational cost for carbon emissions. Where these consultations have been carried out, the cost per tonne has increased in line with the estimated cost of implementing carbon offset solutions.
Any carbon savings associated with the offset fund should be spent on energy and retrofitting projects within the respective borough, whilst being mindful of any conflicts with the Community Infrastructure Levy (CIL) Regulations. The Mayor’s SPG is quite specific with respect to what these funds should be spent on by stating, ‘The borough should ensure that the off-setting measure provides added value – that is, the measure would be unlikely to be funded through other means’. These offsetting measures will be secured through S106 agreements and potentially pooled to provide quantifiable energy efficiency measures on a greater scale.
There is a risk that limitations that exist within certain developments will prevent on-site CO2 targets from being achieved. In these cases there is expectation that all feasible measures will be incorporated and consultation with the borough will be required when a shortfall is shown to exist.
