CRISP aims to develop and validate harmonised criteria and relevant and efficient indicators to measure the sustainability of construction projects particularly within the urban built environment. Through the range of indicators which will be dealt with, the project will contribute to improve the quality of life in urban communities and to promote sustainable development assessed in economic, architecture, environmental, social and cultural terms. Challenges which will be considered through the indicators are for instance linked to the preservation of natural resources, air quality, noise, health and safety, waste, economic competitiveness, employment, deterioration of infrastructure, urban sustainability, environmental loads of construction, socio-cultural aspects, etc.
