This study used a mathematical model to explore the accuracy of extrapolating multi-point blower door test results down to lower pressures at which building…
The impinging jet ventilation system (hereinafter referred to as IJV) has been proposed as a new air conditioning ventilation system. Properties of indoor…
Ventilative cooling can be used as a passive cooling measure to reduce the cooling energy demand of buildings. It can be used during the day, directly…
The outdoor climate is changing and the airtightness and insulation levels of residential buildings are improving. During the warmer season this can lead to…
Many studies have shown that the use of mixed-mode cooling can bring down the cooling load significantly while maintaining satisfactory in door air quality…
For several years indoor comfort is measured in halls of hospitals by architecture students from the Delft University of Technology. Questionnaires and…
Adaptive thermal comfort model has been widely used to evaluate the thermal comfort level of natural ventilation buildings.However, current adaptive…
Ventilation is critical in interpreting indoor air quality (IAQ), yet few IAQ assessments report ventilation rates; even when they do, the measurement…
Measuring ventilation rates in occupied dwellings is challenging but represents the conditions that occupants experience. This paper explores the…
Infiltration is an uncontrolled contribution to ventilation in a building and can contribute significantly to the total ventilation rate, particularly in…
Indoor air quality is the chemical, physical and biological properties that indoor air must have to not cause any negative impact on occupants’ health and…
Installing Natural Ventilation (NV) system in office buildings leads to the reduction of energy consumption of heating, ventilation and air conditioning (…
Building energy simulation (BES) and Airflow network (AFN) programs generally incorporate wind pressure coefficients (Cp) estimated from secondary sources,…
This study aims to experimentally evaluate the influence of the combination of a supply only ventilation, called here positive input ventilation, and…
Guaranteeing high indoor air quality and high degree of user satisfaction at the same time is one of the challenges when improving the energy efficiency of…
The mainstream of air-conditioning system for medium and small sized buildings is conditionally air mixing ventilation with ceiling cassette unit of…
Recently in Japan, many buildings introduce packaged air-conditioner (hereinafter, this is called “PAC”) as an air conditioning equipment. Most of the PACs…
The present paper describes the design improvement of a single-room ventilation unit. This ventilation system presents many advantages, however, several…
The purpose of this paper is to summarize the status of promising low carbon building services solutions fitted for a low emission building stock in urban…
Energy use in buildings has a significant influence on the global energy demand and environmental impacts. Among all building systems, heating, ventilation…
