“…The presented analyses generally accord well with the results of parametric study research on the effect of glazing type and size on annual heating and cooling demand for Swedish timber-frame offices, Bülow-Hübe (2001) and lowenergy houses, Persson (2006a) and Persson (2006b), taking into account of course differences in climate, as well as with some statements from design guidelines for comfortable low-energy homes considering the climate in Milan, Pagliano et al (2007). Furthermore, the obtained results show a relatively good coincidence with the values for energy demand related to the different glazing area sizes with different glazing types for the case study in Amman, Hassouneh et al (2010), taking into account some differences in external air temperature and duration of solar radiation considered in the calculations.…”

“…Bouden (2007) investigated whether glass curtain walls are appropriate for the Tunisian climate. The influence of windows on the energy balance of apartment buildings in Amman, Jordan, is analysed in a study performed by Hassouneh et al (2010). In general all of the presented studies deal mainly with the influence of variable parameters on the energy performance of buildings of different types (residential, offices, public) and mainly of massive construction systems.…”

This paper presents the reasonability of using an increased proportion of glazing surfaces in prefabricated timber-frame buildings with a special focus on energy efficiency by using an enlarged glazing area in the south façade. The research is based on a case study of a two-storey house built in a prefabricated timberframe structural system taking the climate data for Ljubljana into consideration. Parametric analysis is performed on the variation of an increased proportion of the glazing surface's impact in the south side of the building according to the total surface of the south façade (AGAW) as a basic variable. The analysis was carried out on different exterior wall elements having different thermal properties, while the rest of the parameters, such as the ground plan of the model as well as the active systems, roof and floor slab assemblies, climate condition, etc. remain constant. The basic theoretical contribution of the presented research is the transformation of a complex energy related problem to only one single independent variable (U wall -value) which becomes the only variable parameter to determine the optimal glazing area size value (AGAW opt ) for all contemporary prefabricated timber construction systems.

“…A number of studies on the topic of lighting in residential buildings have evaluated daylight availability and the potential for savings in artificial lighting with various geometries and window sizes [7][8][9]. Studies on reducing the heating and cooling demand in residential buildings have considered the influence of window orientation, size and glazing type and suggested that south-facing window size is important for reducing heating demand [10][11][12][13]. However, a study by Persson et al [14] on the performance of passive houses in Sweden has shown that window size is not that important any more for the reduction of heating demand.…”

Appropriate window solutions are decisive for the design of 'nearly zero-energy' buildings with healthy and comfortable indoor environment. This paper focuses on the relationship between size, orientation and glazing properties of façade windows for different side-lit room geometries in Danish 'nearly zero-energy' houses. The effect of these parameters on space heating demand, daylighting and thermal environment is evaluated by means of EnergyPlus and DAYSIM and presented in charts illustrating how combinations of design parameters with minimum space heating demand can be selected within a solution space defined by targets for daylighting and thermal comfort. In contrast with existing guidelines, the results show an upper limit for energy savings and utilisation of solar gains in south-oriented rooms. Instead, low U-values are needed in both north-and south oriented rooms before large window areas lead to reductions in space heating demand. Furthermore, windows in south-oriented rooms have to be carefully designed to prevent overheating. Design options for prevention of overheating, however, correspond well with options for low space heating demand. Glazings with solar control coating are therefore obvious alternatives to dynamic solar shadings. Regarding room geometry, deep or narrow southoriented rooms show difficulties in reaching sufficient daylight levels without overheating.

“…Another research was done on eight types of windows oriented towards four main geographical directions and ultimately the most appropriate direction for each type of window was determined (Hassouneh et al, 2010). Furthermore, the impact of window fittings on saving energy was studied.…”

Saving fossil fuels and the use of clean sources of energy lead to reduce in building operating costs, protect the environment and people's health. Windows are the most vulnerable part of building where energy loss occurs. Double-glazed windows are very effective in keeping inside temperature isolated from outside; thereby, saving electrical and thermal energy. The current study estimates the numerical changes in cooling and heating load in case of replacement double-glazed window with single-glazed window and calculates saving level for this replacement. In this context, this paper presents a model of real samples taken in Mashhad climate. To ensure the accuracy of the simulation results, real results were compared with electricity and gas bills. To calculate energy related parameters such as cooling load, heating load, the consumption of gas and electricity, the energy simulation software (Design Builder) was used. The research method was a quantitative analysis based on energy consumption modeling, associated with building windows which comes in four sections. The field study was also used to compare with real electricity and gas bills. As the first stage, samples of the plan were identified, based on the observation of climate models and library studies. Then, simulation parameters such as window materials and internal and external walls were considered. The simulation was performed based software's parameters and model limitations were determined based on thermal, lighting, climatic and architectural parameters. Finally, the experimental and practical data were used to determine the validity of the model under Mashhad climate conditions. Overall, the results indicated that double-glazed windows could save 50% of entire building loads, 0.2% on power consumption, 16.2% on gas and 12.4% on overall households' energy consumption.
