The glazing area in residential buildings in temperate climate: The thermal-energetic performance of housing units in Lisbon
HighlightsSeveral options with 20%–80% of façades in glazing are presented under conditions considered.Solutions with glazing area more than 60% of the façade greater attention in the cooling season.Solutions with glazing area less than 40% of the façade greater attention in the heating season.Shading devices and ventilation showed a greater potential for improvement, up to 75% and 40%.
AbstractThis work aims to provide information related to issues of comfort and energy consumption, with emphasis on fractions of residential buildings with different transparent areas located in temperate climate, especially those that have more than 60% of the façade in glazing (window-to-wall ratio).The study was developed in different phases, based on geometric models verified through experimental and numerical studies, which are capable of representing the main typologies found in the Portuguese building stock.These models were used allowing the development of a solutions Matrix (current solutions mapping in performance verification process using the software EnergyPlus) and parametric studies, resulting on an information set (descriptive and visual) of interest available to the professional Architect; which allows to verify, identify and quantify the different effects and influences on the thermal behavior of units with such characteristics (large transparent areas), with overall results that may differ up to 75% only when changing a single parameter in units with large glazing areas.Through the results is possible to observe an array of options and solutions (20%–80% of facade in glazing, including those of large proportion) under the reference conditions considered. Thus, the reader can easily obtain enough information to make required and desired decisions in the initial phases of the project.
