“…The results can be further analyzed through the ANOVA to identify the effects of experimental conditions, errors, and the importance of factors. For the statistics of the F-value distribution (F v ), the value of F v is compared to a critical value of a significant level, which is normally set at 0.05 or 0.01 [ 21 , 49 , 60 ]. The impact of the selected factor on the test results is considered to be significant if it is greater than the critical value, and vice versa.…”

“…Moreover, the WINDOWS program [ 65 ] is used to calculate the heat transfer from exterior windows and the solar heat gain from the glazing. EnergyPlus calculations have high accuracy and are mainly used to predict building energy consumption, and their simulation results have been validated in numerous analytical, comparative, and empirical cases [ 49 ].…”

“…In the meantime, we can discover based on the above studies whether add Trombe walls [ 9 , 10 , 11 , 49 ] and insulation materials [ 8 , 14 ] for non-transparent envelopes (exterior walls or roofs) or replace high-performance transparent envelopes (exterior windows) [ 35 , 40 , 44 , 45 ], which all were designed to achieve indoor thermal comfort and energy saving by improving the thermal performance (or parameters) of the envelope, but all were limited to a single factor. Followed by most of the research on energy-saving strategies for envelopes was limited to a certain climate or a specific building type and the optimal configuration of envelopes under different climatic regions has not been well solved.…”

“…Therefore, the model adopts the predominant wind direction in Xichang during summer, and the predominant wind direction in Xichang is north-south [11]. The meteorological data used for the weather energy of Xichang in the numerical simulation were obtained from Chinese Standard Weather Data (CSWD) files, which were downloaded from the website [54] and are suitable for China [55]. In the numerical simulation, the meteorological data for summer days in the Xichang area were selected, and therefore the outside temperature was set at 300 K and the wind speed was 3.3 m/s.…”

Natural ventilation is a way to reduce the energy consumption of building operations and improve the indoor living environment comfort. The venturi cap is designed with a roof, grille and wind deflector to intensify the natural ventilation of buildings. The structural parameters of the venturi cap were designed using an orthogonal design. Fluid analysis software was used for numerical simulation, and variance analysis was used to study the importance of seven influence factors: the width of the roof opening, the roof slope, the height of the wind deflector, the horizontal width of the wind deflector, the angle of the wind deflector, the angle of the grille, and the spacing of the grille slices. The results show that the most significant influencing factor is the width of the roof opening, while significant influence factors include the angle of the grille and the horizontal width of the wind deflector. Additionally, the optimum parameter combination for ventilation performance at the research level was put forward, with the proposed combination achieving a volume flow rate of 5.507 m3/s. The average temperature of the horizontal plane at a height of 1.2 m above the ground was 3.002 K lower than that without a venturi cap, which provides a reference for the optimization of indoor ventilation design in buildings in the Xichang area.

“…Most of the above research regarding ventilation strategies was mainly focused on simulation methods, although some studies adopt and justify their simulation methodology, which is sufficiently deemed accurate and valid, and some have been conducted specifically on ventilation shafts focusing on the courtyard, solar chimney, and Trombe wall of domestic residential buildings [6,[17][18][19][20][21][22][23][24][25][26]. However, due to data collection constraints in obtaining real data, only a few were validated with field measurement results.…”

Thermal Performance of Single-Story Air-Welled Terraced House in Malaysia: A Field Measurement Approach

et al. 2020

The provision requirement of 10% openings of the total floor area stated in the Uniform Building By-Law 1984 Malaysia is essential for natural lighting and ventilation purposes. However, focusing on natural ventilation, the effectiveness of thermal performance in landed residential buildings has never been empirically measured and proven, as most of the research emphasized simulation modeling lacking sufficient empirical validation. Therefore, this paper drawing on field measurement investigates natural ventilation performance in terraced housing with an air-well system. The key concern as to what extent the current air-well system serving as a ventilator is effective to provide better thermal performance is to be addressed. By adopting an existing single-story air-welled terrace house, indoor environmental conditions and thermal performance were monitored and measured using HOBO U12 air temperature and humidity, the HOBO U12 anemometer, and the Delta Ohm HD32.3 Wet Bulb Globe Temperature meter for a six-month duration. The results show that the air temperature of the air well ranged from 27.48 °C to 30.92 °C, with a mean relative humidity of 72.67% to 79.25%. The mean air temperature for a test room (single-sided ventilation room) ranged from 28.04 °C to 30.92 °C, with a relative humidity of 70.16% to 76.00%. These empirical findings are of importance, offering novel policy insights and suggestions. Since the minimum provision of 10% openings has been revealed to be less effective to provide desirable thermal performance and comfort, mandatory compliance with and the necessity of the bylaw requirement should be revisited.
