The impact of the work motivation on the occupants’ work performance of serial one-figure addition task and proofreading task was studied in two types of experiments, i.e., type A of cool condition (22 deg C) and type B of neutral condition (25 deg C). Du
Consumer Confidence/CFL Quality: What are we trying to answer? ???? Who/What is a consumer? ???? What is consumer confidence? ???? What is CFL quality (to the consumer)?
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.
Parameter identification techniques are a powerful tool for the determination of thermophysical properties of building components. However, their correct application often demands a certain degree of experience.Especially in short or/and heavily disturbed data sets a formal use of a parameter identification software can lead to completely wrong results.This paper illustrates these problems by means of some simulation calculations and encourages to a discussion about possible solutions.
