LoginReports on the detailed design of Birchensale Middle School, and how the design team has incorporated PROBE lessons into the specification. The school is over 30 years old, naturally ventilated and lightweight in construction.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
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.
This paper illustrates the airtightness and ventilation performance of a recently built ecological house in Helsinki, Finland.
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.
We investigate the airtightness of 12 French non-residential buildings, by means of experimental fan-depressurization tests.
Ventilation plays an important role in the RT 2000 regulation. The ventilation system is of course taken into account, but also the building envelope airtigthness on which this paper focuses.
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.
The NEN 5128 "Energy performance of dwellings and residential buildings- Determination method" [1] describes a procedure to calculate the energy performance coefficient EPC. The requirements are given in the Dutch Building Decree [2].
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.
A potential conflict may exist between energy saving and good indoor climate.
This paper summarizes part of the work held at ENTPE within the framework of the IEA Annex 35 project.
Air filters may be used to reduce indoor airborne concentration which is one of the main indoor air pollutants. Air filters performances have to be measured in order to be able to select the right product for a given application.
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 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.
Ventilation performances in existing buildings are not well known, in France. They are not often checked. This paper shows how a method for checking the performance of ventilation could be applied in France.
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 briefly exams the role of the building envelope in determining the internal environmental conditions in buildings and the scope for holistic design of building services and building envelope.
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.
The performance of a Ventilated wall component under real weather conditions was tested, during two weather seasons, winter and summer.
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.
