Evaluation of the impact of internal partitions on energy conservation for residential buildings in Serbia

In Serbia, around 50% of energy is used in built environment and most of it for 6-month heating in residential buildings. Because of actual international efforts to protect environment, energy conservation in heating in residential buildings is an issue of permanent research interest. In this paper, we tried to determine how type of partitions inside a residential building influences energy consumption and demand for houses in cold climate and consequently energy conservation. For a typical house in Serbia, by using software HTB2, it was evaluated how its heating depends on six applied types of partitions. It was found that (1) the house with glass-wool partitions would have the minimum yearly heat consumption, (2) the house with masonry partitions would require heaters of minimum size, (3) the house with siporex partitions would require the lowest investment in partitions and heaters, and (4) the house with glass-wool partitions would yield the highest net savings during the life cycle of the house.     

A model for the evaluation of energy conservation investments

Awareness of the need to conserve energy has increased in recent years. In Sweden the Government supports not only research in this field but also measures which can cut back on energy consumption. For instance, special subsidies and loans are granted with the aim of reducing energy usage in the building sector. In this article the problems of energy conservation in the building sector have been analyzed from an economical point of view.A model is constructed which shows how different factors affect the profitability of energy-saving investments. It is formulated as a dynamic control model in which the effect of energy-savings has been chosen as state variable and the investments made in energy conservation at a certain point of time as control variable. A sensitivity analysis is carried out to permit a discussion of how taxes, subventions, energy price trends and technological advances affect the solution obtained.The value of this article lies in its identification of a method for analyzing the impact of various factors on the profitability of energy-saving measures in the building sector.

Comfort and energy conservation: A need for reconciliation?

This paper is focused on background issues which currently underlie attempts to reconcile comfort with reduced consumption of fuels in buildings in Britain. Two specific topics are considered; first, developments which have taken place in environmental design and, second, those which have occurred in comfort research in this country over the past thirty years. Developments in both these fields are presented as having contributed to making the idea of habitable spaces in buildings in Britain synonymous with the notion of consuming finite fossil fuels. Physiologically-grounded, orthodox comfort theory is questioned as an adequate basis for understanding how people judge internal environments in buildings they occupy since social issues, concerned with what constitutes an acceptable environment, are also identified as significant. environment, are also identified as significant.

A dual-mode system for harnessing roofwater for non-potable uses

In a limited land area of about 630 km² Singapore has an average annual rainfall of 2250 mm. As catchment area is limited and about 60% of water is being imported, there is a continuous search for new sources. One such source is roofwater from high-rise buildings in which almost 84% of the population lives. The main objectives of this paper are to study the feasibility of collecting the roofwater from the north spine of the Nanyang Technological University (NTU) campus and to utilise it for non-potable uses. A well-established simple input–output model incorporating a dual-mode system (DMS) of operation has been used so as to ensure that all the collected roofwater from an area of 38,700 m² is used only for non-potable purposes. The design parameters were optimized leading to a rainwater storage tank linked to the existing water tanks with pump cut-in and cut-out electrodes placed at depths of 1 and 1.5 m above the base of the tank that will ensure that the supply of water will always be available for the non-potable uses. The overall system will realise a monthly saving in water consumption expenditure in the NTU complex by about S$18,500.00.
