“…Similarly, ref. [39] uses a TE air-cooling system in order to cool the glazing surfaces' airflow in hot climates during summer, this reduces the thermal discomfort of the occupants significantly and reduced the cooling loads of the window as well. The result of the study shows that after a certain number of modules, increasing TEM count on the windows do not contribute to reduction in energy, in fact, in some cases it was also responsible for increase in the consumption of energy and had no considerable impact on energy savings.…”

Countless years have been spent researching the strategies necessary for improving the energy consumption of buildings globally. There have been numerous attempts at achieving both passive solutions and enhancing and optimising the existing active systems. This paper seeks to review, analyse and summarise the possibilities of using thermoelectricity in two different contexts to the integration with buildings, integrated thermoelectric systems, and non-integrated thermoelectric systems. The utilisation of thermoelectricity in cohorts with existing renewable technologies and the utilisation of thermoelectric systems that operate individually, both have the potential to provide the occupants of a building with conditions pertinent to thermal and visual comfort. The results in this paper are classified according to the integration types of thermoelectric systems within different parts of the fabric of a building while maintaining an active role in enhancing the building envelope and self-contained thermoelectric systems that sustain a passive role for the same. The introduction to this paper also gives a very broad and surface-level insight into categorisation of different kinds of thermoelectric systems that are being studied and researched across the world.

“…The radiative heat transfer coefficients between surfaces and indoors and outdoors are calculated as follows [9] : (9) (10) In Equation ( 7), T sky is the sky temperature given by [9] : (11) Also, T mr in Equation ( 8) is the mean radiant temperature of surfaces surrounding the interior glass surface, which is assumed to be equal to indoor air temperature [15] . 1 and 3 are the total of the long-wave radiative heat exchanges between channel-side surfaces of the interested glass pane and the channel-side surfaces of the other zones.…”

“…While most of the researchers working on the ventilated window focused on evaluating thermal performance and energy efficiency [7][8][9][10][11][12] , The IAQ and energy consumption analysis has been the subject of limited studies. Gosselin and Chen [6] carried out experimentally validated computational fluid dynamics (CFD) simulations on a proposed dual airflow window to optimize the window design.…”

Energy efficiency and indoor air quality (IAQ) are two crucial required features in a building. Simultaneous improvement of energy efficiency and IAQ in a building can pave the way for obtaining a green building certification. This paper examined the performance of the airflow windows’ supply and exhaust operating modes in energy-saving and providing IAQ criteria. The analytical zonal model coupled with the airflow network model was used to evaluate the system’s thermal performance and the induced airflow. The simulation was done for an office building located in Shiraz, Iran. The results showed that the energy performance of ventilated windows is positive in nine months of the year. Compared to a conventional double-glazed window, the maximum energy savings is about 10%, which occurs in August. It is predicted that using ventilated windows in office buildings in Shiraz can improve the window’s thermal performance by an average of about 5%. The results also showed that ventilated windows could provide the fresh air needed for the building in 250 days of the year to achieve the desired IAQ index (based on ASHRAE 62.1 standard). Furthermore, the effects of glass aspect ratio, airflow channel thickness, and the size of inlet/outlet openings on energy efficiency and IAQ of the suggested window were studied. Results indicated that in the climatic conditions of Shiraz, the exhaust operating mode is much more efficient than the supply mode.

“…The authors reported a maximum COP of 0.45 and a minimum temperature of 17 °C. In a recent study, Khalvati et al [23] analyzed the effects of air temperature attenuation, working interval time, and the number of modules on the performance of a thermoelectric cooling system. Operating the thermoelectric air-cooling system during a short period reduces energy consumption while using it for a longer time might raise it.…”
