The volume provides a valuable overview of the Commission's current activities in research on solar radiation data and in the development of solar energy applications in buildings. It contains the proceedings of the second contractors' co-ordination meeting in the third four-year R&D programme (1985 - 1988) in these two fields. The research contractors' reports presented in this book give a full account of activities at an important stage in the programme where most projects have completed their preparatory stages and productive research is now fully underway. A feature of the reports is the pattern they illustrate of working groups in which practically all of the Member States are represented, co-operating in the attainment of common goals within a co-ordinated European programme. The meeting presentations were made by the contractors on the objectives of their projects, progress made in the research, and future work plans and priorities. The meeting was also important in improving communications between the research groups, exposing opportunities for co-operation and collaboration, and monitoring progress. Among key achievements reported in the area 'Solar Radiation Data' is the implementation of a network of measuring stations at eight proto-typical sites throughout Europe. A test phase has been completed and results are now being obtained which will contribute to improved prediction of the technically-usable solar radiation at particular sites on the basis of currently- available site-specific data. There were first reports from two recently begun contracts: project SUNSAT, in which statistical data on available solar radiation energy in areas of the world with sparse radiation data networks will be derived from measurements by geostationary satellites; and EUFRAT, which will prepare climatological data required as inputs for solar system design tools. In Solar Energy Applications to Buildings' the group concerned with solar system model development and validation described a series of microcomputer software packages which it now has available. Considerable progress has also been made in the development of a complete, consistent and reliable set of test procedures for solar storage systems, and evaluation of a first series of tests to verify new storage models has begun. The increased emphasis now attached to passive solar R&D because of its economic and architectural attractions is reflected by the number and scope of projects which relate to this technology. At the largest scale the team developing a computer-aided management system for urban renewal which makes use of passive solar demonstrated its progress through sophisticated computer visualisations of a high graphic quality. The wide-ranging concerted action which is intended to remove obstacles to the use of daylighting in office buildings reported on the results of its first year's endeavours, including a number of important studies, analyses and critical reviews. Laboratory studies of human reactions to changing thermal environments are underway which will provide a basis for a mathematical model of thermal comfort in transient conditions, such as are experienced in passive solar buildings. At a more detailed level, progress is being made in developing automatic control systems for passive systems. University/industry co-operation is bearing fruit in proposals for sophisticated but adaptable optimising controllers, while other work is developing a multi- tracer gas system for measuring the movement of air between zones in buildings. Features of the latter include the suitability of the system to rapid installation in buildings, low capital cost, and usability while the building is occupied. The project PASSYS has the twin aims of increasing confidence in passive solar simulation models and design tools, and developing reliable and affordable test procedures for passive solar components. Finally, the special issues which arise in ensuring that the results of this richly diverse research effort are rapidly made available to the European industry in the most effective manner were also addressed.
