The challenge in designing facades and selecting windows in commercial buildings is balancing many issues and criteria. This fact-packed handbook outlines the basics of glazing selection and provides critical information and performance data on the energy efficiency, interior environment, technical, and life-cycle-cost considerations that drive window design decisions in commercial buildings.

In the quest for improving building energy efficiency raising the level of performance of the building enclosure has become critical. As the thermal performance of the building enclosure improves so does the overall energy efficiency of the building. One key component in determining the energy performance of the building enclosure is windows. Windows have an integral role in determining the energy performance of a building by allowing light and heat from the sun to enter into a space. Energy efficient buildings take advantage of this free solar energy to help offset heating energy consumption and electric lighting loads. However, windows are traditionally the least insulating component of the modern building assembly. With excessive use, larger window areas can lead to greater occupant discomfort and energy consumption from greater night-time heat loss, higher peak and total cooling energy demand from unwanted solar gains, and discomfort glare. As a result, windows must be carefully designed to not only minimize heat loss, but also effectively control solar gains to maintain both a thermally and visually comfortable environment for the appropriate climate region and orientation. In this thesis, a complete analysis of window assemblies for commercial office buildings is presented. The analysis is divided into three sections: the Insulated Glazing Unit (IGU), the Curtain Wall Section (frames), and the overall energy performance of a typical office building. The first section investigates the performance characteristics of typical and high performance IGUs, specifically its insulating value (Ucg), its solar heat gain properties (Solar Heat Gain Coefficient, SHGC), and its visual transmittance (VT) through one-dimensional heat transfer and solar-optical modeling. Mechanisms of heat transfer across IGUs were investigated giving insight into the parameters that had the most significant effect on improving each performance characteristic. With a through understanding of IGU performance, attainable performance limits for each of property were generated from combining of different glazing materials, fill gases, and coatings. Through the right combination of materials IGU performance can be significantly altered. The U-value performance of IGUs ranges from 2.68 W/m2K (R-2.1) for a double-glazed, clear, air filled IGU to 0.27 W/m2K (R-21) for a quint-glazed, low-E, xenon filled high performance IGU. The second part of the thesis looks at the thermal performance of curtain wall sections that hold the IGU through two-dimensional heat transfer modeling. Similar to the IGUs, heat transfer mechanisms were studied to by substituting different materials to determine which components are crucial to thermal performance. From this analysis improvements were made to typical curtain wall design that significantly reduces the overall heat transfer within the frame section, producing a high performance curtain wall section. With simple modifications, a high performance curtain wall section can reduce its U-value by as much as 81% over a typical curtain wall section, going from 13.39 W/m2K to 2.57 W/m2K. Thus significantly reducing the U-value of curtain wall systems, particularly for smaller windows. The final part of the thesis examines the impact of typical and high performance windows on the energy performance of perimeter offices of a high-rise commercial building located in Southern Ontario. An hourly simulation model was set up to evaluate both the annual and peak energy consumption of a typical perimeter office space. The office faced the four cardinal directions of north, east, south, and west to evaluate the effect of orientation. The model also included continuous dimming lighting controls to make use of the available daylight. The effect of exterior shading on perimeter space energy performance was also investigated with both dynamic and static exterior shading devices. The results of the simulations revealed that window properties have very little influence on the energy performance of a high internal heat gain office, that is typical of older offices with less energy efficient office equipment and lighting and a higher occupant density. Conversely, window properties, particularly the insulating value of the window, has a greater effect on the energy performance of a mid to low internal heat gain office that is typical of most modern day commercial buildings. The results show windows with lower U-values yet higher SHGC are preferred over windows of similar U-values but with lower SHGC. The results also indicate that both static and dynamic shading have very little effect on energy performance of mid to low internal heat gain offices. From this analysis optimal window areas in the form of window-to-wall ratios (WWR) are presented for each orientation for mid to low internal heat gain offices. The optimal WWR for south-facing facades are between 0.50 to 0.66, and 0.30 to 0.50 for east-, west-, and north-facing facades, while for high internal heat gain perimeter spaces window areas should be kept to a minimum.

Buildings are responsible for over 30% of the heat loss in the building envelop. However, window creates a sense of spacious for the room and provides natural lighting, view and ventilation for the interior space. It is important to consider windows with the highest rate of energy consumption in the building envelop, being five times more than the other elements. With proper selection of window glazing and their design its help to minimize the energy consumption level. The limitation of this research is that it has only focused on vertical and fixed window plates without any shading devices; how they will minimize the heat loss by improving the glazing material or replacing the glass material to block the infrared radiation and prevent unwanted heat gain in summer period, in the Colored Building of the Faculty of Architecture at Eastern Mediterranean University, North Cyprus.

Today's energy-efficient windows can dramatically lower heating and cooling costs associated with windows while increasing occupant comfort. However, consumers are often confused about how to select the most efficient window for a residence. Furthermore, how this efficiency is defined is another problem that needs to be addressed.Energy consumption is a scale that is used for defining energy efficiency. In most cases, the amount of energy that is used during the products service life (operational energy) will be measured as the total energy consumption of the product. However, the amount of energy that is used for producing a product is also as much important as operational energy, which should be taken into consideration.In this thesis, it was attempted to provide useful recommendations for selecting the most efficient window glazing systems with regard to their overall energy consumption, using a Life-Cycle Energy Analysis (LCEA) method. The effect of using thirteen (13) different commonly used types of glazing systems on the annual energy use for a residential building was compared in various climate conditions across the U.S. Moreover, the amount of energy required for producing these glazing systems were identified. The results obtained from the analyses of these two phases of the study was used to create a simple set of guidelines, which can be utilized to select the most efficient glazing systems in terms of overall energy consumption based on different climate condition.

The book explores advanced building-facade daylighting design practices based on diverse energy and human-factor performance metrics. It also defines effective daylighting by rethinking the simplified approach to glazing and facade systems to incorporate the local climate and the needs of building occupants as critical drivers of building performance, design solutions and technological innovation. It discusses state-of-the-art approaches in the context of simulation-based design workflows, innovative technologies and real project case studies, all targeting low and net-zero energy solutions that enhance occupant comfort. Readers benefit from a comprehensive approach that improves the feedback loop between design intent and performance in use. The book is intended for architects, lighting designers, facade engineers, manufacturers and building owners/operators, as well as advanced students.
