Efficient Option

In current research, building modelling and energy simulation tools were used to analyse and estimate the energy use of dwellings in order to reduce the annual energy use in multifamily dwellings. A three-story residential building located in Kabul city was modelled in Revit and all required parameters for running energy simulation were set. A Total of 126 experiments were conducted to estimate annual energy loads of the building. Different combinations from various components such as walls, roofs, floors, doors, and windows were created and simulated. Ultimately, the most energy efficient option in the context of Afghan dwellings was figured out. The building components consist of different locally available construction materials currently used in buildings in Afghanistan. Furthermore, the best energy efficient option was simulated by varying, building orientation in 15-degree increments and glazing area from 10% to 60% to find the most energy efficient combination. It was found that combination No. 48 was best option from energy conservation point of view and 120-degree rotational angle from north to east, of the existing building was the most energy-efficient option. Also, it was observed that 60% glazing area model consumed 24549 kWh more electricity compared to the one with 10% glazing area.

The paper is oriented on the hygrothermal microclimate of residential interiors in reconstructed building. The questionnaire survey has showed significant increase in number of allergies, respiratory diseases and occurrence of fungi after reconstruction. In order to find causes, experimental measurements of hygrothermal microclimate were carried out. The long term high values of relative humidity were found out and the link with number of efficient natural ventilation was searched for. Ventilation once a day was usual, what was proved as insufficient. Dwellers were informed about right way and number of ventilation. Furthermore, measurements proved decrease of air humidity, but not sufficiently. It was proved that nobody was able to achieve recommended number of ventilation and almost all of them considered it annoying and unreal to sustain. The biggest problem was proved night 7 hour interval. Therefore allergic and respiratory problems were significant in the morning. In conclusions of paper is suggestion for solution of researched problem.

The paper presents a review of architectural and design techniques which were characteristic for residential development in the second half of the XVIII century in St. Petersburg. During that period, there was formed the urban planning, volumetric spatial and constructional structure of residential buildings, which later, in the XIX - early XX century, became a typical solution for residential development in St. Petersburg. The fi rewalled residential house was usually built along the perimeter of the possessory plot of land with an inner courtyard formed inside. The residential house consisted of a two-span front building and one-span side buildings located along the perimeter of the site. The constructional system of a residential building in the second half of the XVIII century was a vaulted-beam scheme along the longitudinal walls. The main construction structures are described, such as brick walls with subsequent fi nishing, strip stone footings based on wooden joists, roofs built on wooden batt er rafters in a cold att ic with no heating.

India is a rapidly growing economy witnessing continuous growth in the housing sector and living standards. The main focus of construction practices still remains on the architectural aspects of the buildings, largely unconcerned with their environmental impacts. The current thrust of concern for building sector, especially in developing countries, is to assess the environmental impact of buildings in a quantifiable way for implementing sustainable measures and achieving sustainability. Lifecycle assessment (LCA) is a comprehensive tool that is used worldwide to assess the environmental performance of any product or a process. This paper assesses the environmental impact of a residential house at planning stage on the basis of lifecycle assessment (LCA) considering various stages of building like construction, operation (for service life) and demolition, and identifies the hot-spots in the form of building components, materials, and stages.

The author regards as an approximate measure of insolation the difference of the maximum temperatures observed by two similar thermometers one in the sun, and the other in the shade, disturbing influences being as much as possible avoided in both cases, and the observations being confined to those days on which the sun shone sufficiently clearly to cast a distinct shadow during some part of the interval between noon and 4 p .m . Comparing the differences of insolation in different parts of India and in different seasons, he is led to regard insolation as dependent greatly on relative humidity. Thus, generally speaking, it is greater on the seaboard than in the interior of India.

Abstract Energy efficient design is a high priority in the national energy strategy of European countries considering the latest requirements of the European Directive on the Energy Performance of Buildings. The residential sector is responsible for a significant quantity of energy consumptions from the total amount of consumptions on a worldwide level. In residential building most of the energy consumptions are given mainly by heating, domestic hot water and lighting. Retrofitting the existing building stock offers great opportunities for reducing global energy consumptions and greenhouse gas emissions. The first part of the paper will address the need of thermal and energy retrofit of existing buildings. The second part will provide an overview on how various variables can influence the energy performance of a building that is placed in all four climatic zones from Romania. The paper is useful for specialist and designers from the construction field in understanding that buildings behave differently from the energy point of view in different climatic regions, even if the building characteristic remain the same.
