The spread of energy-efficient buildings
Which factors play a role in the spread of energy-efficient technologies in the building sector? How can the behavioural choices of the parties concerned be influenced? This project will provide important answers to these questions.

What are the consequences of structural change in the building industry?
The building industry consumes a great deal of energy and generates high volumes of waste. It is not always immediately apparent whether or not the countermeasures that are taken are sustainable. This project will explain the cause-and-effect relationships in the building industry and elaborate models that will visualize the consequences of structural change in this sector.

Cities go underground
The horizontal expansion of cities is inconsistent with the principles of sustainable development. Resulting problems are greater traffic congestion, environmental pollution and inefficient water supplies. The urban underground possesses a great deal of potential that could contribute to the sustainable development of cities.

Air conditioning resulting in rising energy consumption
How can thermal comfort in buildings be improved, without resorting to energy-intensive air conditioning systems? How do stakeholders behave with regard to air conditioning or the need to cool buildings during the summer?

The urban site considered as an ecosystem
Methods for describing entropy flows from modern thermodynamics are used to characterise processes of the urban metabolism with a view to achieving sustainable development.

Sustainable planning and renewing of the sanitation sector
Due to the longevity of infrastructures, planning strategies are needed which include social, economical and technological changes. The project therefore elaborates a forwardlooking approach for sustainable regional infrastructure management on the basis of the sanitation sector.

Mitigating the heat island effect in cities
Buildings are responsible for more than half of global greenhouse gas emissions. Urban structures modify the local climate in ways which result in a heat island effect. This study aims to extend the capabilities of atmospheric models to facilitate accurate urban climate predictions.

Micropower as a great opportunity
Reducing the use of non-renewable energy for buildings is an important step towards the sustainable development of the built environment. The concept of "micropower" offers opportunities, but it has not yet reached the market. Strategies and research on the preferences of consumers are needed.
