Highlights Evaluating the energy performance of mixed-mode ventilation in office buildings. A methodology for deriving archetypes based on empirical and literature data. Assessing energy performance in archetypes and comparing to local benchmarks. Favoring natural ventilation in mild temperate climates can reduce energy consumption in office buildings.
Abstract The growing concern regarding environmental issues and energy efficiency has led to an increased interest in natural ventilation as a cost-effective alternative to reduce energy consumption in buildings. In a mild temperate climate, promoting natural ventilation using operable windows can significantly improve indoor thermal comfort in office buildings for a significant part of the year. However, archetypes for office buildings that include operable windows and use mixed-mode ventilation in this climate are not common in the literature. Typically, these buildings feature individual offices where the installation of an air conditioning system is a decision made by the owner or tenant, as window or split systems used in such spaces are not pre-installed. Thus, there is a gap in investigating how these buildings are designed, used, and operated. Therefore, this study aims to develop archetypes for office buildings with mixed-mode ventilation and compare their estimated energy consumption with a local energy benchmark developed for a mild temperate climate. The archetypes were defined based on three different floor plans: rectangular, triangular, and square-shaped. The archetypes were simulated, and their electric energy consumption ranged from 53.4 to 60.2 kWh/m2.year. These values were higher than the average consumption of the local benchmarking. The difference is believed to be due to the overestimation of the use hours of building systems, as air conditioning usage was predicted based on temperatures for window opening and closure. Nonetheless, these archetypes can be applied in other locations with mild temperate climates to analyze their potential in reducing energy consumption, as they consume significantly less energy than fully conditioned buildings.
