Having minimised the requirement for building servicing, we must then look to establish the best way to deliver the energy efficiently to the spaces which need it. Using dynamic analysis, we can interrogate which systems are the most appropriate for the building and can evaluate multiple servicing strategies for the same building to obtain the optimal blend to satisfy the requirements of Part L, carbon reductions for planning, lifecycle cost, BREEAM credits or simply their annual energy requirements. This exercise can be undertaken at concept stage so that the building is formed with the right amount of plant space in the right position, with enough space allowed for horizontal and vertical distribution & harmonisation with the structural strategy.
