Shortwave thermal performance for a glass window with a curved venetian blind

Effect of installing a venetian blind to a glass window on human thermal comfort

“…Chaiyapinunt and Khamporn [25] have shown that the transmitted solar radiation through a glass window with an attached venetian blind can be calculated by combining the optical properties of the glass window and venetian blind using the matrix layer calculation suggested by Klems [11,12]:…”

“…Forced convection 3 Â ðjT o À T a jÞ 0: 25 Free convection (17) where T smrto ¼ mean radiant temperature due to surface temperature and solar radiation evaluated from the value of operative temperature, ( C).…”

“…U R ¼ total uncertainty of the data R. U i ¼ total uncertainty of the independent variable (x i ) of the data R. [25] have estimated the uncertainties associated with measured solar radiation (i.e. sensor Fig.…”

“…transmits both shortwave and longwave radiation) and nonspecular. The followings studies considered the heat transmission through the glass window with an attached venetian blind: Klems [11,12]; Klems et al [13]; Klems and Warner [14]; Pfrommer et al [15]; Collins and Harrison [16]; Chantrasrisalai and Fisher [17]; EnergyPlus [18]; Yahoda and Wright [19]; Khun [20,21]; Wright et al [22]; Chaiyapinunt and Worasinchai [23,24], and Chaiyapinunt and Khamporn [25]. Only a very limited number of studies have considered thermal comfort aspects as part of the thermal performance of the glass window with the venetian blind.…”

A Study of Optimal Energy Consumption Measures for Building Façades with a Parametric Combination of Blinds, Lighting and HVAC Systems

“…A window maximizes the solar heat gain within a building in winter, but the net result is an increase in cooling load in summer, presenting a considerable risk to be avoided as much as possible. However, because it is not possible to change the façade of a building every season, solar radiation is normally controlled with subsystems such as blinds 1,2 .…”
