“…However, the effect of important parameters such as wall-to-window ratios or shading coefficients on solar heat gain in the building was not investigated in that research. Yang, et al [21] investigated the optimal window-wall ratio and the adequate glazing type in varied air-conditioning system operation modes of domestic buildings for individual orientation in a hot summer-cold winter climate. Their results indicated that the overall energy consumption increased with an increasing window-wall ratio, especially for east-or west-oriented windows.…”

Abstract:Recently, considerable attention has justifiably been directed towards energy savings in buildings as they account for up to 20-40% of total energy consumption in developed countries. In the United Kingdom, studies have revealed that buildings' CO 2 emissions for account for at least 43% of total emissions. Window panels are a major component of the building fabric with considerable influence on the façade energy performance and are accountable for up to 60% of a building's overall energy loss. Therefore, the thermal performance of glazing materials is an important issue within the built environment. This work evaluates the impact of solar window films on the overall energy consumption of an existing commercial building via the use of a case study U.K. hotel and TAS dynamic simulation software. The study results demonstrated that the impact of window films on the overall energy consumption of the case study hotel is approximately 2%. However, an evaluation of various overall energy consumption components showed that the window films reduce the annual total cooling energy consumption by up to 35% along with a marginal 2% increase in the annual total heating energy consumption. They can also provide overall cost and CO 2 emissions savings of up to 3%.

“…Yang et al [88] showed that the total energy consumption would increase when the WWR is increased, as half of the energy in a building is lost through the window [89]. Thus, it is important to determine the optimal WWR for different building facades to reduce such loss [90].…”

“…Troup et al [92] demonstrated that WWR is statistically significant at most of the levels of glazing when predicting the cooling, lighting, and ventilation energy use, but they are not statistically significant for the heating load in office buildings in the US. Marino et al [93] highlighted that the optimal value of WWR is not strongly influenced by the climate conditions, and also the insulation features of the envelope does not have a strong effect on this parameter, but instead the influence of WWR on the total energy consumption are associated with the operation mode of air conditioning systems, orientation of outside windows, and the glazing types of windows [88].…”

The building envelope plays a significant role in the energy performance of buildings and windows are a key element in transmitting heating and cooling between the indoor and outdoor environment, and hence an adequate window system is one of the most important retrofit strategies of existing buildings for energy conservation. Therefore, this study presents a method with a theoretical case study to examine the improvement of energy efficiency in a typical high-rise residential building through window retrofitting. A building energy design model in Designbuilder along with a building information modeling (BIM) model in Revit are developed, with 20 common potential glazing alternatives being analyzed to predict the potential energy savings in the same case building with identical orientation located in a variety of climate zones in China. Based on different parameters and considerations, the results demonstrated that the currently relatively expensive low-e window glazing has the best energy performance in all climate zones, but is sufficiently close to conventionally glazed windows in its energy efficiency to discourage its adoption at present, and that, instead, a single dark conventional glazed window is preferred in a hot summer/warm winter climate, double dark traditional glazing in a hot summer/cold winter climate, and a double clear conventional window in a cold climate. Based on the simulated results, an indicative suggestion was provided to select an adequate window system for residential building retrofitting in the studied climates or similar climatic regions.

“…Relative average disaggregated end uses and losses of energy in buildings due to the window, ventilation opening and shading is 11 percent [6,7]. Yang et al found that the total energy consumption increased when the WWR increased [10]. Nonetheless, the use of shading device as passive control system could save energy by 0.03-13.14 percent [11].…”

Globally, building sector currently consumes around of 40 percent of total energy and it is predicted to further rapidly increasing up to 80 percent by 2040. This study aims to investigate some design options to achieve thermal comfort and reduce energy consumption. In Indonesia, building sector consumes around of 37.8 percent of the total nationwide energy consumption. Computer simulations using EDGE and EnergyPlus were performed in this study to obtain embodied energy value and obtain operative temperature respectively. EDGE uses monthly quasi-steady-state calculation method based on the European CEN5 and ISO 13790 standards while EnergyPlus uses dynamic simulation model based on hour-by-hour (or higher resolution) outputs. A single storey building with 12 different parameters and design configurations including one base model were developed for this simulation. Some parameters were evaluated such as wall materials, roof materials, Window to Wall Ratio (WWR), window shading, ventilation opening, solar PV and ceiling fan. The simulation results showed that modification of U-value of wall and roof, increased WWR value, presence of window shading, additional rooster above windows with WWR of 9 percent and additional ceiling fans would optimize the embodied energy saving of building by 20.2 percent. Under these circumstances, final embodied energy saving of building was around of 63,939 MJ. This result was 10,837 MJ higher than that of the base model. Simulation results showed that the operative temperature mostly did not exceed the upper comfortable limits.
