The project is a part of IEA SH&C Task 23 'Optimization of Solar Energy Use in Large Buildings'. The objective is to ensure the most appropriate use of solar energy in building projects, to optimise
The overall goal of this project has been to provide the knowledge and the understanding that can lead to an increased efficiency for ac/dc power systems complying with EN61000-3-2 in wide input range
The project report describes the design and construction of a 1-1.5KW high efficiency Grid connected Building integrated Photovoltaic Power Generator for use in Houses or larger Photovoltaic Plants
Within the project, the most promising design of PV/T components have been identified: 1) A water-heating collector with the PV cells acting as absorber in a direct thermal contact with water piping
The aim of this preliminary project has been to develop a 'self-learning' district heating meter using a neural network to control consumer heating installations. Two different neural network
The activities were: Development of improved components, analysis of durability, contacting, improving the methods, materials development, studies of mechanisms and of defect and structural chemistry
The objectives of this research project are to reduce energy consumption of electrostatic precipitators and to improve precipitation efficiency, particularly for small dust particles.
Use of Drag Reducing Additives, DRA, in circulating district heating water can reduce network pressure losses significantly. However, a serious obstacle to the practical implementation of this concept
The energy consumption by the actual ploughing can be separated into two essential main elements: The power needed to break the soil; Friction between the soil and the various parts of the plough. In
The development primarily consists of improved computational tools, combination of existing processes as well as introducing new methods and processes.
The background for the project is the fact that it has become technically and economically feasible to use variable speed control of all active components (compressors, fans, pumps) in a refrigeration
The solution proposed in this project is to modify the cylindrical air gap of an electric motor by applying a non-linear axial profile (called Shark profile).
The main goal of ECBCS Annex 36 is to provide the educational building decision-makers with sufficient data, information and tools to improve their learning and teaching environments by improving the
The project has demonstrated a building integrated ventilation system with the ducts system installed outside the facade. The air ducts are installed in a solar tower parallel to the staircases in the
In the autumn of 1999 the IC plant at Nordborg Power Plant was commissioned, and following that the emissions and emission reductions of the plant were measured.
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
