Sustainability, compliance and environmental modelling can quickly become overwhelming when multiple consultants, deadlines and planning requirements are involved.
At XDA Consulting, our role is to make that process clearer, smoother and easier to manage.
Founded by Dr Dianne Bowles, XDA works closely with design and project teams to provide practical sustainability advice, technical modelling and environmental assessments that support projects from early planning through to completion.
Whether it’s BREEAM, daylight analysis, whole life carbon assessments, overheating assessments or energy modelling, our approach is always the same: clear communication, reliable technical work and support that helps keep projects moving.
