LoginThe 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].
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.
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.
Earth-air heat exchangers can be used to reduce energy consumption in building ventilation systems. The idea is to pre-heat air in winter and pre-cool air in summer using the thermal capacity of the soil.
Building-integrated photovoltaic (PV) systems are increasingly common in developed countries and have the potential to contribute significantly to electricity generation as a benign alternative to fossil fuel generation.
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
Thermal bridges are the typical locations for moisture and mould problems in buildings. Low surface temperatures in combination with a high humidity level in buildings can lead to severe problems and complaints by the occupants.
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.
The paper reviewed the supply opening models of describing inlet boundary conditions for indoor airflow simulation firstly. Then examples of isothermal free air jets from a grille are presented to validate full representation of supply openings.
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.
