Following calculations of potential energy savings, several types of earth-air heat exchangers have been coupled to buildings in novel concepts for passive heating and cooling of ventilation air.
The "Intelligent Facade" is seen as a central element in the evolution of building form and building fabric to provice environmental control and comfort.
Most dwellings in the United States are ventilated primarily through leaks in the building shell (i.e., infiltration) rather than by whole-house mechanical ventilation systems.
A major concern of those wishing to limit the energy use in buildings is the growing trend towards installing air-conditioning in new and refurbished buildings.
Ventilation plays an important role in the RT 2000 regulation.
This paper summarizes part of the work held at ENTPE within the framework of the IEA Annex 35 project.
The aim is to develop a new method for comfort in settings with high thermal load in buildings that do not require continuous cooling but cooling only during shorter periods. Example of such buildings is schools.
For over 20 years, the AIVC has been a key player in developments in technical knowledge on ventilation and related issues, and has always been very active in the dissemination of information.
Dynamic insulation is a very good example of a ventilation system integrated with the building envelope. The paper describes two recent studies carried out at Nottingham on dynamic insulation.
COOLHOUSE - cooling buildings in southern Europe using innovative ventilation strategies. | 2001 | English
The Coolhouse project is exploring the viability of alternatives to air-conditioning in southern European countries using innovative passive and low energy cooling and ventilating techniques, with an emphasis on ground cooling.
DCV systems have proved to be energy saving with correct IAQ in previous studies. In order to achieve correct performance, these systems must be properly designed and tested.
General presentation and use of a method of calculation of consumption of RAC (Room air conditioners). | 2001 | English
When studying improvements on room by room air conditioning appliances (RAC), it is necessary to know for how long these appliances function and which is their effectiveness - EER - on average (or Seasonal) known as SEER.
In this paper, measurement and simulation results are presented that demonstrate the energy performance of a recently built ecological house in Helsinki, Finland.
This paper is an overview of the work carried out during a 3year EPSRC funded project investigating the important factors in Supply Air window design. The structure and some of the main conclusions of this work are presented here.
Why and how is airtightness stimulated in the proposed new energy performance regulation for the Flemish Region. | 2001 | English
The airtightness performances of buildings and ventilation systems can have a major impact on the indoor climate (IAQ, thermal comfort,...) and on the energy performance.
Laboratory test procedures to evaluate thermal and fluidodynamic performances of the climatised room. | 2001 | English
In this paper the experimental results of the measurements obtained after the completion of a test room realised in the laboratories of the Dipartimento di Energetica dell'Universit di Ancona and the development of the monitoring system are report
The main problem in natural ventilation is that its efficiency depends very tightly on the meteorological conditions : high wind velocity and outside temperature lower than inside are optimal conditions for efficient ventilation.
Increased global warming and deterioration of the ozone layer have stimulated interest in the use of renewable energy systems.
Airtightness of 12 non residential large buildings. Results from field measurement studies. | 2001 | English
We investigate the airtightness of 12 French non-residential buildings, by means of experimental fan-depressurization tests.
