“…Daugelis tyrėjų ieško būdų kaip įgyvendinti natūralaus vėdinimo sprendimus, kurie užtikrintų ne tik mažesnes energijos sąnaudas, bet ir išlaikytų reikiamą oro kokybę, arba ją pagerintų (Lukiantchuki et al, 2020). Izadyar atliktas tyrimas rodo, jog didžiausias natūralaus vėdinimo potencialas pastebimas aukštuose bei vidutinio aukštumo pastatuose (Izadyar et al, 2020).…”

“…According to many studies, a balcony can significantly transform the airflow pattern inside and outside of buildings [56][57][58][59][60][61][62]. It was proved that the presence of a balcony could improve natural ventilation on the indoor ambient, increase thermal comfort, and consequently reduce the need for mechanical ventilation and, therefore, reduce the energy consumption in buildings [3,59,60,[63][64][65].…”

A Review of Balcony Impacts on the Indoor Environmental Quality of Dwellings

2020

Balconies are an ancient architectural archetype that are being increasingly considered in multi-family buildings of high-density cities. This paper aims to provide a comprehensive review of the impacts of balcony types on the indoor environmental quality (IEQ) and energy consumption of dwellings. Of the reviewed studies, 69% were published during the last decade, making it evident that awareness of the positive impact of balcony spaces is continuously increasing. The literature review allowed us to identify three balcony spaces according to their morphology and their boundary system: open balcony (OB), glazed balcony (GB), and eliminate balcony (EB). It was concluded that these balcony types produce relevant impacts in four factors that contribute to the indoor environmental quality: thermal comfort, indoor air quality, visual comfort, and acoustic comfort. Practical design recommendations and constraints were provided according to distinct climatic conditions and building technologies. This review also explored the assessment methodologies used for the optimization of the balconies on the design process. The literature highlighted the lack of a comprehensive study about the impact of balconies in mild and Mediterranean climates, as well as the knowledge limitations concerning the balance between the impacts on IEQ factors.

New passive thermal comfort system using three renewable energies: Wind catcher, solar chimney and earth to air heat exchanger integrated to real‐scale test room in arid region (Experimental study)

Summary Thermal comfort is one of the ancient‐new challenges of the arid region population and responsible for more than 40% of energy end‐use. Renewable energy can be a solution to this problem. In the present paper, the potential of renewable energies to ameliorate thermal comfort and reducing energy consumption in building sectors is experimentally investigated. Three renewable‐based applications are used: wind‐catcher (WC), solar chimney (SC), and earth to air heat exchanger (EAHE). The three techniques are connected to a real‐scale test room and investigated using in‐situ measurement. The contribution of each technique is discussed separately. Temperature, humidity sensors, and anemometer are used to study parameters affecting thermal comfort. Obtained results show that the use of wind‐catcher could provide in the presence of wind an internal airflow of 3.8 m.s−1 which reduces inside room temperature by 6°C. A solar chimney creates a difference between its inlet and outlet air temperature by 5.9°C and increases the kinetic energy of hot air leaving the solar chimney which is replaced by cool air from outside and other devices outlet (EAHE and WC) and increases internal airflow even with the absence of winds. The earth to air heat exchanger increases the outlet air temperature in winter by 8°C and reduces it by 12°C in summer. Inside test room hygrometry is also ameliorated by the use of EAHE. Analyzing the new system (test room + WC + SC + EAHE) shows an important amelioration of inside thermal comfort. A difference between inside and outside test room temperature is found: reduction of 13°C in summer, and a gain of 10°C in winter. The new system leads to better inside test room thermal comfort conditions and to reduce energy consumption by almost 50%. The present study presents the first experimental investigation of using three renewable energies in the same building to improve thermal comfort. Using real scale room and in‐situ measurement gives a realistic idea and results show that green energy could improve the thermal situation and energy saving. This is an original work to motivate building designers, especially in the arid region to use more than one renewable energy to ameliorate thermal comfort in both summer and winter seasons.
