Objetivo Objectives and problems to be solved: Completion of the development of a novel glazing system having the following characteristics: In summer, it reduces the penetration of solar radiation to the building interior, while allowing an unobstructed view. It lowers the cooling load, saving energy, and decreases thermal discomfort near the glazing, to an extent that may render external shading devices unnecessary. In winter, it allows solar space heating, but increases visual comfort in the heated space by eliminating the glare typical of a direct gain solar openings; prevents local overheating caused by exposure to direct solar radiation; and reduces damage to furniture and equipment in the heated space caused by sunlight. Description of work: The benefits of the proposed glazing system are realized mainly through the conversion of short wave (solar) radiation to convective heat and long-wave radiation. The first stage of the project focuses on the detailed aerodynamic design of the window, and on the development of 'a model of the performance of the window as a function of climatic conditions, aerodynamic design and optical properties of the glazing. The proposed glazing system requires an innovative reversible frame, incorporating two glazing assemblies: a clear glazing (usually double, often with low-e coating) to provide a weatherproof seal, and an absorptive glazing to provide solar control. The two glazing assemblies, and the ventilated channel between them, must be able to rotate together through 180o to enable the transformation from winter mode to summer mode; In each of the two configurations, the glazing assembly incorporating the clear glass must provide a weatherproof seal, capable of fulfilling current performance codes in the window industry. An appropriate frame, which must also provide the desired aerodynamic characteristics, is developed in the second stage. Prototype glazing systems are assembled and installed in test cells, which are monitored to evaluate performance under different climatic conditions. The absorptive glazing used at each of the sites has different optical properties, suitable for warm summer conditions and for cold winter conditions at each of the sites. The experimental data allows validation of the model developed in the first stage. This enables design guidelines to be developed in order to customize the optical qualities of the glazing system in accordance with specific environmental conditions found in different parts of Europe, and to establish expected energy savings in each of them Expected Results and Exploitation Plans:- A model of the performance of the window as a function of climatic conditions, aerodynamic design and optical properties of the glazing.- A working prototype of the new glazing system.- Experimental evaluation of the glazing system under various climatic conditions. Climate-specific characteristics of the system appropriate to different climatic regions in Europe, and a measure of the expected benefits on thermal comfort, visual qualities and energy consumption.
