Working areas

Buildings are the biggest energy consumers, consuming almost 50 per cent of all energy. Therefore, architecture must and can make a contribution towards improving the environment.

Consultant on renewable energy systems (RES), including Solar Architecture, the integration of transport and waste management, new technologies, and the use of passive thermal design to improve comfort.
Consultancy on sustainability projects.
Member of official delegations and research committees in Europe, China, Latin America, UK and Australia.
Advisor on sustainable urban design to government and city councils.
Member of international scientific steering committees of EU and ARC-funded research projects.
Organiser of conferences, seminars, and workshops, with a focus on: 'Sustainable strategies in urban design'; 'SolarCity'; 'Sustainability in the developing World'.

Areas of Sustainability Research and Research Focus

Improvement of the existing building stock, and how to transform inefficient structures into 'green' buildings, using passive and renwable energy technologies.
The sustainable City of the Future: urban development strategies and a cohesive understanding of new urban design principles for energy-efficient cities.
Renewable Energy Research
Theory and methodology of environmentally sustainable architectural design, incl. tall buildings and large structures.
Urban regeneration and environmentally-driven urban renewal strategies, with a focus on applied environmental sustainability to improve the city's and building's performance, identify the appropriate densities, public spaces, and integrate public transport.
Low energy architecture, with special interest in mixed-mode / natural ventilation systems, solar cooling, and passive solar buildings. This includes: Energy-efficient building envelopes, incl. double-skin facade technology and retro-fitting strategies.
Climatic responsive design for buildings in the tropics / subtropics.
Co-Editor of the 'Journal of Green Building'
