An object reconstructed for residential purposes approved to be not sufficiently air tight. With methods that are generally known as inappropriate, it was tried to improve the air tightness subsequently to a reasonable level. Therefore, joints were formed elastically, cavities were filled with insulating material and slots were foamed with construction...
An indoor thermal simulation was conducted in a traditional house in a mountain area of Nepal for the purpose of thermal improvement in winter and saving firewood. The results are as follows:
In building studies dealing about energy efficiency and comfort, simulation software need relevant weather files with optimal time steps. Few tools generate extreme and mean values of simultaneous hourly data including correlation between the climatic parameters. This paper presents the C++ Runeole software based on typical weather sequences analysis.
Volatile organic compounds (VOC) are major indoor air pollutants. Physical models that have been developed to predict VOC source (emission) and sink behavior (sorption) of building materials, commonly adopt the conventional convection approach using third-kind boundary condition assuming quasi-steady convective mass transfer in fluid (air). In this study, conjugate mass transfer models were developed to investigate the validity and application limit of the assumption.
When designing district heating serving different buildings, an architectural engineer should suggest optimal operation policy of heating, based on social aspects and on minimizing costs for used energy and for investment in building heaters. In this paper by using HTB2 software, the energy simulation was carried out for two small Serbian residential buildings with different heating timing (starting and ending time of heating). These buildings had different types of partitions: one with thermal insulation layer and one with bricklayer.
This study aims to verify the advantages of district heating and cooling (DHC) systems in terms of energy efficiency. From the measurement data, the parameters that characterize the energy efficiency of a heating/cooling plant are identified for DHC and an individual building. A Simulation model that considers the difference in these parameters is developed. This model examines both the advantages and disadvantages of DHC systems and the effect of each parameter.
This technical monograph is one of a set produced as part of the ‘REVIVAL’ project – an EU Energie Programme supported demonstration project of energy efficient and sustainable refurbishment of non-domestic buildings in Europe. The monographs explore some of the main energy and comfort issues which arose during the Design Forums held with each of the six sites. The four monographs are entitled:

If indoor radon levels are to be significantly reduced across Europe it is essential to ensure that allnew buildings built in areas affected by radon are protected against radon.In the United Kingdom the Building Research Establishment Ltd (BRE) have been carrying outresearch on behalf of the Department of the Environment, Transport and the Regions (DETR) todevelop protective measures for use in new buildings. This work commenced in the mid-1980sand has resulted in the development of a range of practical cost-effective techniques for providingradon protection in new UK buildings.
Radon as an indoor air pollutant has been extensively researched worldwide over the past thirtyyears. However, radon is only one of several other important pollutants present in the indooratmosphere. In addition to radon as an ubiquitous indoor pollutant, the simultaneous presence ofother non-radiological pollutants, such as toxic alkanes found in the working environment, needs tobe accounted for its integrated mitigation approach.
