The potential of controlling techniques for an electrochromic device is investigated in a systematic way, using both experimental and theoretical tools. Concerning the theoretical part a model was developed in the TRNSYS environment and validated against experimental data. These data were collected from experiments, which were carried out in a PASSYS test cell with a movable wall. Having established a good model performance several cases of window types (such as a 4mm clear window and a low-e double glazing) and controlling strategies for the electrochromic device are simulated.
An energy balance over an urban area and over a rural one, reveals that the first case is always more complex than the last one. The urban context is able to change all the energy transferences mainly due to its own layout. Thus, analysing all the energy transferences one by one, we can find how they affect in a different way depending on the surroundings, among other influences.
The aim of this paper was to examine the effect of two different dust collection devices, widely used in epidemiological studies. The device used for dust sampling has a significant influence on the amount of dust collected and may lead to uncertainty in the measurement of biomarkers.
This paper provides scientific evidence that electrified homes in South African rural villages have lower levels of air pollution compared to the non-electrified homes using fuel or wood. The measured air pollutants were RSP (stationary respirable particulate matter), the CO in the kitchen and the CO on the child.
The deposit of particles lower than 5µm diameter, depends on the airflow path within the room along with the strength of the ventilation.This parameter has to be taken into account to predict particle indoor air quality. For that study, a numerical model
Has the DOAS the ability to provide sufficient air movement to meet comfort requirements ? The test results from a DOAS delivering the minimum ventilation air via overhead high induction diffusers are presented in this paper.
Standard 55-2004, on thermal Environmental Conditions for Human Occupancy was recently published and approved by ASHRAE and ANSI. This article gives an overview of the key features and limits of applicability of that standard.
In hot summer days, in Bucharest the air temperature is over 36°C and the relative humidity exceeds 50 %. That explains the big air-conditioning demand for tertiary buildings. This paper deals with an experimental and a numerical investigation of an air-c
In this paper, an example of how to use the dynamic building and system simulation to design, determine and optimize the characteristics of a heating and cooling system of a school building in southern Germany, is presented.
This paper is the summary of the 2003 AIVC/BETEC conference with its different parts: Health and Building Science, Building evaluation, Single-building studies, Experimentation, Building science, Strategies and New directions.
