Timothy Dunn is a mechanical engineer who began his career at VOS Group in late 2002. Tim has developed a sound knowledge base of multi-disciplinary building services consulting. In particular, Tim has a keen interest in energy efficient and sustainable design solutions. Tim is experienced in mechanical services design and development, building energy consumption modelling, thermal and climate analysis, day-lighting analysis, computational fluid dynamics (CFD) studies and building greenhouse emission rating/reduction.
The current focus of Tim’s work is involved with computer modelling and simulation of building projects for thermal performance, energy consumption, fluid dynamics and day-lighting assessment. Through each project Tim utilises a hands on approach to realistic building modelling and simulation in order to reflect practical installations. By providing guidance to the various design teams involved on building projects, Tim ensures the achievement of targets in relation to thermal performance, energy consumption and/or greenhouse emission, day-lighting and ventilation. Tim has been involved with mechanical services design and documentation, energy efficiency modelling and sustainability assessment for a variety of high profile projects across all building sectors. |
