Energy Statements are a common requirement by Local Planning Authorities across the UK. They demonstrate how the developer will address specific local objectives, like CO2 emissions or renewable energy targets. We typically adopt the following ‘Lean, Mean, Green’ energy hierarchy to help us develop an efficient and economical strategy.
We initially focus on reducing energy demand through passive measures such as improvements to the thermal envelope, a natural ventilation philosophy where suitable and reducing building air leakage.
Consideration is then given to increasing the efficiency of building services such as boiler and chiller plant, reduced specific fan powers, incorporating daylight and occupancy sensing into the lighting system.
Only once the above measures have been considered, do we look at adding low and zero carbon generating technologies (except where mandatory for local planning requirements). During early stages, where designs are still flexible, more than one ‘Green’ technology may be viable. We can therefore carry out a more detailed feasibility study to establish the optimum solution based on energy, CO2 and financial benefits.
Statements produced by Carbon Futures can take many forms depending on the scale of development, but it will generally be prepared at pre-planning stage and accompany your planning application. This will demonstrate how the development will address renewable technology obligations and CO2 emission targets.
