Assessment of exposure by size-resolved indoor and outdoor particle sources in residential buildings

Abstract High-quality data on indoor climate and energy collected in buildings is required to deepen our understanding of building performance. The aim of this work was to investigate the relationship between the indoor and outdoor climate in Danish residential buildings. Field data was collected in 45 apartments from April 2019 to November 2020. Internet of things (IoT) devices were installed to record the temperature, relative humidity and CO2 concentration in the central corridor of each apartment. High CO2 concentration (above 1,000ppm) and overheating were observed in the apartments. The changeover between the heating mode and the free running mode occurred between 11.1 to 13.6°C of outdoor air temperature. The temperature setpoints of the heating systems were around 20.6-22.3°C, which could be useful values to feed building simulations in order to achieve more realistic predictions of indoor climate and energy. The results of this study improve our understanding of indoor environmental quality in residential buildings at a national level.

Most commonly, residents are always arguing about the quality of their high rise residential property. A growing number of high rise residential buildings in Malaysia with differing light well were designed by the structural design and planning since 15 years ago. This light well is defined as an intermediate space area between indoor and outdoor of the high-rise residential building. The questionnaire survey of three high rise residential buildings that have different sizes of the light well and building designed were conducted to make clear the occupants' evaluation about the real quality conditions of the buildings. As a result, the quality of light well is clearly satisfied and well managed by the property manager in their high rise residential buildings.

The building industry is associated with several environmental impacts. In considering the total building lifecycle, the use phase has a strong influence on the level of impact. According to the literature, the use phase of residential buildings represents up to 92% of energy consumption, constitutes 95% of water consumption (indoor and outdoor), accounts for 45% of the weight of materials used, and produces 50% of the waste (maintenance, repair, and renovation). Green building and certification programs used in North America, such as BOMA-BESt®, LEED®, and Living Building ChallengeTM, aim to reduce the environmental footprint of housing. However, while these certifications provide a useful framework for practices related to buildings and their systems, a documentary analysis shows that they do not adequately take into account the use phase of residential buildings. The purpose of this paper is to show that consideration of the use phase is inconsistent with the impacts associated with it.

In this paper, the present usage of natural ventilation of rural residential buildings in ChaoShan area is in-depth studied through the analysis on thermal environment data of continuous monitoring indoor and outdoor in the transition-site season from several representative typical rural residential buildings in Guangdong ChaoShan area. It revealed the differences between “cheng” and patio, and the fact that wind pressure ventilation is still dominant, because that buoyancy driven ventilation is difficult to form in such houses during transition seasons when generally rain comes with low temperature. And it also pointed out the effect that the elements of modern house (such as: sliding window, window screens, window security and large household appliance) are implanted as the raise of population and living standards had brought to the thermal environment on traditional buildings.
