Abstract The main goal of the research line this project follows is the development of new methods for the analysis of natural ventilation systems used in buildings, in order to facilitate a massive implementation of these systems in the constructive sector. Characterizing natural ventilation systems as building components is a complex task which requires a deep analysis of the problem. Due to this complexity, the present project has the goal of designing and evaluating these methods in two particular natural ventilation systems: ventilated façades and solar chimneys. The methods to be developed are expected to be clear and simple enough to be introduced in the Building Technical Code (CTE in Spanish). A new scheme to evaluate global behaviour (energetic and interior comfort) of this natural ventilation systems integrated on buildings will be developed. From a scientific and technical point of view the following objectives are posed: ? To develop a methodology for the design and analysis of the global performance of these systems including the development of a new software based on computational fluid dynamics (CFD) and its coupling to annual simulation tools already existing in the market. ? Evaluate and select systems and façade’s components able to overcome the existing design limitations and to allow an increase in the offer of products designed for specific climatic conditions. ? Demonstrate the benefits of using this methodology through the building of prototypes and experimental validation of their response in real conditions ? Let the methodology and selected systems to be commercially available, to be competitive and to be approved by the CTE. The most important innovation represented by the NATVENT project is the application of advanced design and standardization methods to the field of natural ventilation systems. As in other industrial fields, the concept is expected to evolve from the design for a specific project to the massive production. Besides, this project will focus on the following innovations: ? Development of simple strategies for easy implementation of natural ventilation systems on buildings. ? To encourage a level of critical mass which will allow a real uptake of these natural ventilation systems ? To demonstrate how specialized and intelligent construction can deliver self sufficient buildings with no CO2 consumption The methodology to be followed to achieve these objectives is based on the previous experience of CIME, Instituto Eduardo Torroja and Barcelona Supercomputing Centre (BSC) and is supported by the companies ULMA Hormigón Polímero, PICH-Aguilera and AIGUASOL-Sistemes Avançats d’Energia Solar Tércmica which contribute with another point of view coming from the construction and architectural sectors.
