Sustainable Design Solutions


FLATT prepare designs for building services and renewable energy systems that ensure the optimum balance between meeting carbon reduction targets and capital costs.

Legislation and planning may require the use of renewables. As Low Carbon Consultants, we avoid ‘greenwash’, taking a practical and informed approach to their provision.

Our design proposals create buildings that minimise their environmental impact, reducing energy consumption and carbon emissions and hence the extent of renewable technologies required.

We’ll advise you on the most appropriate low carbon or renewable technology, the benefits and how they integrate into the building to provide an optimum cost effective solution.
