“…In office buildings, when decreasing the window to wall ratio, these problems are significantly reduced. Facades with external shading devices highly decrease office building's cooling energy demand, positively impacting in the occupant's thermal and visual comfort [7,28]. Conclusions of these studies are based on daylighting and thermal performance simulations.…”

Overheating, glare, and high-energy demand are recurrent problems in office buildings in Santiago, Chile (33°27'S; 70°42'W) during cooling periods. Santiago climate is warm and dry, with high solar radiation and temperature during most of the year. The objective of this paper is to evaluate the thermal and daylighting performance of office buildings transparent faç ades composed of three different complex fenestration systems (CFS). Each CFS contains a different external shading device (ESD): (1) external roller, (2) vertical undulated and perforated screens, and (3) tilted undulated and perforated screens. The study was carried out by in situ monitoring in three office buildings in Santiago, Chile. Buildings were selected from a database of 103 buildings, representing those constructed between 2005 and 2011 in the city. The monitoring consisted of measuring the short wave solar and daylighting transmission through fenestration systemsby means of pyranometers and luxometers, respectively. This paper shows measurements that were carried out during summer period. A good performance is observed in a building with the external roller system. This system-applied to a northwest faç ade-shows a regular and high solar and daylighting control of incoming solar radiation. OPEN ACCESSSustainability 2014, 6 2787The other two ESD systems evidence a general good performance. However, some deficiencies at certain times of the day were detected, suggesting a non-appropriated design.

“…Pino et al (2012), defines thermal comfort as the physical and psychological wellness of an individual when temperature, humidity, and air movement conditions are favourable for the activity that has to be developed. According to Indraganti (2011), people either modify the environment or adapt themselves behaviourally or do both to remain comfortable in a thermal environment, through several adaptive control actions.…”

Abstract:The amount of solar radiation through the fenestration of a building into the interior space is a key factor in assessing the indoor comfort and the eventual energy used in cooling off these spaces. In predominantly hot humid regions like Ghana which receives sunlight all year around, buildings and for that matter windows should be oriented to minimize solar gain and maximize natural ventilation. Windows are possibly the most complex and interesting elements in every habitable structure. Heat loss and heat gain through a window will not only depend on the type of window and its properties alone but also the size and the position of the same. This paper describes an investigation into the consequence of window sizes (varied wall-to window -ratio) and it"s positioning on indoor thermal comfort for residential buildings in Ghana. A typical room of 3m x 4m was parametrically simulated using the Tas tool. Various window sizes with diverse WWR were then probed into with varying positions (low, middle and high). The result showed that the ideal window to wall ratio for achieving almost comfortable indoor conditions should be between 10 to 40%. Meanwhile, the various positions of the windows did not seem to have any effect on the indoor temperature values since all the values were the same. The study should lead to an improved residential design with appropriate window sizes and correct positions which will ensure indoor comfort and thereby reducing the total energy used in cooling.

“…In [14], they analyzed the impact of shading and control systems on the energy demand for cooling and for lighting. Other studies similarly showed the potential energy savings concerned with high-efficiency lighting systems, window coating, occupancy profile and behavior or daylightlinked controls, with regard to quite different climates, from tropics to northern Europe [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. The differences in lighting performances, demonstrated in all these studies, are not taken into account if a constant value is assumed for internal gains.…”

This paper critically discusses the procedure prescribed by the Italian Technical Standards to account for the internal gains in the calculation of the energy performance indices for a building. This procedure is based on a tabular value set depending on the building usage only (e.g., 6 W/m 2 for office buildings), independently of the site and of the controls for blinds and lighting systems. Instead, the paper proposes a new procedure, which relies on the lighting energy numerical indicator (LENI) according to the European Standard EN 15193:2007. Basically, the procedure consists of the following steps: 1) internal gains from lighting are calculated accounting for the integration between electric appliances and daylighting; 2) these gains are summed to the internal gains from occupants and appliances; 3) the global gains are used as input data to calculate the energy performance indices for an office building (for space heating, space cooling, and lighting consumption) following the Italian Technical Standards. The office building which was used as case-study is the Department of Energy of the Politecnico di Torino. This was assumed to be located both in Turin (northern Italy) and in Palermo (southern Italy). In the study, the use of a manual on/off switch and of a photodimming sensor was also compared. For each configuration, the single and the global energy performance indices were calculated comparing two approaches to calculate the internal gains (Italian standard vs. new proposed procedure): a shift of one energy class for the building energy label was observed depending on the approach, which was used. BackgroundThe demand for more energy efficient solutions has risen with the worldwide growing concern about energy consumption. Buildings have been identified to play a major role in potential energy saving and new directives and standards are being issued to bound the integrated energy performance of new or renovated buildings within prescribed limits: the implementation of the European energy performance of buildings directives (EPBD) [1][2][3] at various national levels requires all new buildings achieve a building energy rating (BER) lower than the prescribed target energy rating (TER) for the specific building type. Within the European Union, a formal commitment was agreed to reduce by 2020 the primary energy consumption and overall greenhouse gas emissions by at least 20% below 1990 levels [4]. Following a mandate received from the European Commission [5], the European organization for standardization (CEN) started elaborating the various standards concerned with the EPBD to define a methodology to calculate the integrated energy performance of a building. Although an EPBD-Project Group was established for this purpose, due to the delays in completing the whole process, several countries have already adopted national calculation methods. As a consequence, the energy performance of the same system may be evaluated differently in different countries [6]. With regard to the Italian context, the ...
