Late last year Yeo Valley contacted us about there renewable energy project plans. It was the re-roof and instalation of photovoltaic panels. almost two acres of dairy unit have been re-roofed, one acre of which is now PV cells. The panels estimated output per year is 455,440 kWh.

We were tasked with looking at the existing sheds poor ventilation and designing a new natural ventilation system to create a shed ventilated to the best of standards. The ridges were all changed to protected open ridges of varying sizes depending on stock levels in that area. The biggest issues unusually was air inlets, as it is a very large existing multi span large shed the options were slightly limited but we were able to open up the gable end and sides of the building to allow the required volume of air to enter the building without letting any rain in or creating any drafts.
