    Design, control and optimization of complex fenestration systems of office buildings
    (2016) Uribe, Daniel; Vera Araya, Sergio Eduardo; Pontificia Universidad Católica de Chile. Escuela de Ingeniería
    El sector de edificación consume el 40% de la energía y genera un tercio de las emisiones de gases invernadero a nivel mundial. Las fachadas altamente vidriadas son un elemento común en la arquitectura moderna de los edificios de oficinas que puede producir disconfort visual en los ocupantes y alto consumo energético. Los sistemas complejos defenestración (CFS por sus siglas en inglés) tienen un rol fundamental en el desempeño energético de edificios de oficinas, controlando las ganancias solares y la transmisión de luz visible. El término CFS se refiere a sistemas de protección solar no especulares que redirigen la radiación solar en forma compleja. Los CFS pueden proveer confort visual y térmico a los ocupantes si son diseñados correctamente, reduciendo el consumo de energía de edificios, el sobrecalentamiento y el encandilamiento, mientras mejoran la transmisión de luz visible. Este trabajo presenta la investigación sobre el diseño y optimización de CFS, el cual se divide en: (1) la influencia de lamas hechas de aluzinc sobre las ganancias solares, consumo energético y el confort visual de los ocupantes; (2) caso de estudio del uso de mk Schedule, una herramienta integrada de simulaciones lumínicas y térmicas, para diseñar y/o evaluar las estrategias de control de dos CFS móviles en las etapas tempranas de diseño de edificios; (3) evaluación de algoritmos de control de CFS; y (4) optimización de un CFS fijo bajo criterios de confort visual y consumo de energía.

    Development and validation of a numerical heat transfer model for PCM glazing: Integration to EnergyPlus for office building energy performance applications
    (Elsevier Ltd, 2024) Uribe, Daniel; Vera, Sergio; Perino, Marco; CEDEUS (Chile)
    © 2024 Elsevier LtdGlazing filled with Phase Change Materials (PCMs) or PCM glazing arises as a strategy to improve the office buildings' energy performance by providing thermal inertia to glazed façades. PCM glazing can reduce office buildings' cooling energy consumption in warm climates. Literature shows a good understanding of PCM glazing thermophysical properties. However, nowadays, it is unfeasible to estimate the energy consumption of offices with PCM glazing based on annual energy simulations. Therefore, this paper aims to integrate a novel, developed, and validated PCM glazing heat transfer model for building energy performance applications into EnergyPlus. In order to do this, a numerical heat transfer model of a double-clear glazed filled with PCM based on literature is developed. This model is validated experimentally and integrated into EnergyPlus, a state-of-the-art building energy simulation tool. Annual simulations are carried out for an office room with different WWR, façade orientations, and PCMs in four climate conditions to show the model's capability to estimate the energy consumption and cooling peak load reductions. The results show that double-clear glazing filled with PCM can reduce the energy consumption of an office building up to 9.1 % and reduce the cooling peak loads up to 10.5 % compared to the same office building with a triple-clear glazing filled with argon. The best results were observed in warm climates with significant diurnal temperature variations.

    Use of Different Complex Fenestration Systems in Office Spaces in Chile : Analysis of the Energy Consumption and Visual Comfort of Occupants at the Early Stages of Their Design Process
    (IOP Science, 2020) Bustamante Gómez, Waldo; Molina, Germán; Uribe, Daniel; Vera Araya, Sergio Eduardo
    Office buildings around the world are mostly designed with high window-towall (WWR) facades, regardless of the type of climate where they are located. Chile, a country with a high climate diversity from north to south and from the coast to the Andes, is no exception to this situation. In order to improve the thermal and visual performance of office buildings, it has been shown that complex fenestration systems (SFC), which include an external solar protection system, are effective to control the incident solar radiation and lighting transmission. However, the effectiveness of these systems depends to a large extent on an appropriate CFS design. Some studies of office buildings in Chile show that a high percentage of CFS has not been designed correctly. To support the early stages of the design process of office buildings in Chile and to assist in the design of solar protection systems as part of a CFS, oficity, an easy-to-use tool was designed. In an office space and considering different facades of solar protection systems, the tool allows the development of simultaneous simulations of its total energy consumption (heating, cooling, and artificial lighting), together with the evaluation of the occupants’ visual comfort. The tool performs the simulations in just a few seconds, which makes it appropriate to support the preliminary stages of the building's design process. The tool is compatible with PCs, smartphones, and tablets. The back end of oficity uses EnergyPlus for annual energy simulation and Radiance for annual lighting simulation. The use of these validated software makes the results of the simulations highly reliable. The tool considers 23 different climates of Chile. This research shows the analysis of an office space in different cities of the country, with variations in its orientation and the protection systems that are recommended for different climates
