To achieve the intended results of building, managing and using a property requires knowledge,continuity and communication, which can be assured by a dynamic and flexible quality assurance(QA) system. Such a system, intended to ensure high-quality indoor environmental conditions, hasbeen developed and successfully applied over the last ten years. However, although clients have beenvery satisfied with the QA system and its results, the pressure for energy efficiency improvement hasincreased.
The combined heat, cooling and power production (CHCP) is one of the most interesting methods toincrease the system global efficiency by supplying electric and thermal power needs both in winter andin summer, and at the same time reducing CO2 emissions.Global efficiency increase is related to the use of waste heat which can be also used to producecooling energy by means of a absorption chillers.A CHCP programme is planned in a specific area in the University City of the University of Rome LaSapienza (approximately 1000.000 cubic meter and an energy bill of some 10 M) and it consists of agas

The European Research Area (ERA) in the field of energy in buildings continues to develop dynamically in response to both the market needs and to the ongoing technological and legislative developments. Various networking mechanisms can be applied by key actors in the field to enhance access to research activities and increase the coherence of the scientific community: one such mechanism was formulated in the early 90s by the grouping of research actors from the PASSYS and PASSYS II research and technical development projects funded in part by the European Commission.
Phenomena like thermal inertia are difficult concepts to understand for students, because they are difficult to model or to measure. The control theory, on another hand, is often learned in terms of an abstract theory. We have developed a pedagogic cursus, based on the use of a test bench initially dedicated to the test of solar thermal collectors, in order to allow the students to be in real contact with these concepts.
Objective of this paper is to present results from experimental measurements and computer simulations of thermal behaviour and energy efficiency of the solar double skinned ventilated faade of the Brno Metropolitan Library in Brno in the Czech Republic. Simulations were provided for the period of heating season between September and April and for the reference climatic conditions with hourly climatic data in the format TRY created for the South Moravia climatic region.
As a result of increasing summer temperatures in the UK, it is likely that more dwellings in the future will have air conditioning installed to meet the occupants comfort requirements. This trend will inevitably increase the energy demand for cooling. This study, using computer simulation, estimates the likely increase in domestic cooling energy, under a number of scenarios.
