Overview
Centre for Energy and the Environment
Dr Lash has assisted local authorities with government policy on energy use in buildings (e.g. the Building Regulations and other policy documents). He has also produced several design and sustainability compliance tools for local authorities to help embed sustainability principles within developments. These have included a small project tool for Cornwall Council, and an sustainability tool for all projects for Devon County Council.
Dan formed part of the design team on the award-winning Montgomery Primary Schools and Bideford BSF College acting in the role of sustainability adviser and thermal modeller. He conducted extensive thermal modelling both to inform design decisions (energy, thermal comfort, ventilation, daylight) and to fulfil the compliance requirements of the Building Regulations. He has also been involved in numerous other building projects.
As a Level 5 CIBSE Low Carbon Energy Assessor he is qualified to demonstrate compliance with Part L of the building regulations using dynamic thermal modelling on the most complex building types. He has also conducted evaluations of the University of Exeter’s buildings for the provision of Display Energy Certificates (DECs) and provided advice on how their energy and carbon performance can be improved. Dan is a qualified BREEAM assessor, and is also on the CIBSE School Design group, and the CIBSE Lighting and CIBSE Natural Ventilation Groups. He has undertaken several renewable energy feasibility assessments, and a review of farm scale anaerobic digestion. He has also worked on setting the proxy measures for DSP’s LAA with regard to National Indicators 186 (carbon emissions) and 187 (fuel poverty), and has critiqued masterplans for Exeter City Council
