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.
The SOLVENT window is an innovative glazing system concept that involves the use of a rotating frame, an absorptive glazing and a naturally ventilated vertical channel, in order to improve the balance between the visual comfort and the energy efficiency of windows.
Meteorological measurements required for the development of a design scheme that responds to the local environment are generally recorded by the weather service in stations that are assumed to be representative of the surrounding region. However, no account is taken of the changes in conditions caused by urban development, even though differences between meteorological conditions within cities compared with adjacent rural areas (the heat island effect) may be substantial.
This project presents the development of an algorithm predicting ambient greenhouse air conditions to be used for energy efficiency simulation and control schemes optimization. The climatic conditions considered are temperature, relative humidity, CO2 concentration and solar radiation. The algorithm has two modes of operation, the first simulates the greenhouse while in the second the heating, cooling, humidification or dehumidification, CO2 injection rates are calculated to maintain certain setpoints.
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.
