This project forms the Danish participation in an international IEA working group, which scope was to gather and process monitoring results from 15 low energy houses designed and build during the IEA
The project is concluded with an assessment as to whether Denmark should participate activily in IEA TASK 25, Solar Assisted Air. Conditioning of Buildings. The recommendation is that Denmark should

The project will contribute to an increase in the application of energy saving power electronic systems, which is obtained by the following means: 1) integration / miniaturization; 2) low total costs
Background: 1) Flow friendly silencer and diesel particulate filter technology. 2) Lower back pressure related to market demands regarding attenuation, emission control and space requirements. 3)
The process in an expansion valve implies energy losses, as the change of conditions is only an isenthalpic process, whereas an isentropic change of pressure would result in increased refrigeration
The purpose of the project is to implement, test and verify a calorimetric measuring system for accurate measurement of power losses in the range of 30 to 1500 W, enabling measuring of rotating
In industry separation processes use at least half of the available thermodynamic work. Hence development of alternative technologies, which are e.g. 20% more efficient, could reduce the industrial
The objective of this project was to test the most promising new concept and control strategies for natural and hybrid ventialtion. The project has been carried out in connection with the extension of
The project deals with participation in the work of international organisations concerning heat pumps, refrigeration systems, and air-conditioning systems.
The aim is to establish the technological basis of a reduction of the electricity consumption within the field of industrial pumps. The use covers a wide range from irrigation, heating and cooling
Measurements in four glass melting furnaces at Holmegaard Glassworks have been carried out. Three of these were equipped with FLOX-burners and one with a conventional burner, all supplied by IGA A/S
Several barriers to the application of tube burners for industrial liquid heating exist, such as uncertainty regarding safety of operation and principles of dimensioning. In addition, this heating
The main aim of the project has been to reduce the energy consumption for new buildings by documenting the possibilities for lowering the present energy frame when building regulations are altered in
The Program focuses on the development of methods and procedures for reduction of the energy demands for lighting and ventilation, while at the same time emphasising the necessity of maintaining a
An evaluation of the state of the art of components and energy systems for low energy houses has been carried out. The state of the art of several important areas has been described in combination
The main aim of the project has been to stimulate a development of concrete elements with better insulation and less thermal bridge effect. The aim has been to develop examples of concrete elements
Based on the combined effect on indoor climate and space heating demand in domestic buildings the potential - both technical and economical - for development of energetic improved windows within a
