An experimental study on the environmental performance of the automated blind in summer

Blinds are used widely in numerous buildings to conserve energy and provide for occupants' comfort in the perimeter zone. However, manual or motorized blinds are limited in their ability to reduce energy consumption and to provide comfort because occupants themselves must operate blinds to block direct solar radiation. Thus, the use of automated blinds would more fully exploit the full benefits of blinds.

The use of shading systems in VDU task offices: A pilot study

We registered how eight subjects used their remotely controlled black Venetian blinds in eight individual offices, every 15 min, over a period of 30 weeks. This also included measuring parameters such as the illuminance on the window, the illuminance on the VDU screen, the ambient temperature inside the room, the presence of the worker and the state of the artificial lighting. During the same period, we registered the position of the blinds in seven other offices fitted with manually controlled fabric blinds, through webcam pictures taken every 15 min. There was no further monitoring inside these offices.With the data collected, several hypotheses regarding the use of Venetian blinds in offices were tested. It appeared that office workers were consistent in the way they used their shading system, however it was difficult to draw general conclusions on blind usage. The type of control of the shading system also seemed to be important. Remotely controlled black Venetian blinds were used three times more often than manually controlled fabric blinds. In addition, most of the time users adjusted the tilt of the slats of the Venetian blinds downwards, towards the external ground. We also came to the conclusion that the higher the quality of the VDU screen (in terms of emitted luminance levels), the more likely a worker was to tolerate high levels of diffuse reflections on it, hence taking more advantage of the daylight available.     

百叶遮阳对室内光环境的影响

Solar control: A general evaluation method for facades with venetian blinds or other solar control systems

A general method for realistic performance evaluation of solar control properties of facades for facades with sun-shading or other solar control systems has been developed. It is particularly designed to be used for venetian blinds. It can be used used ‘stand-alone’ or within building simulation programs. The new method has proven to be of great practical value to planning teams of huge office buildings in Germany, Austria and Switzerland. The method is presented in detail in this paper. It can be used either ’stand-alone’ (without building simulation) for comparisons of different facade variants or within building simulation programs. Some parts of the proposed methodology could be used in standards (e.g. EN13363) or to improve the accuracy of building simulation programs which are currently on the market. Practical experience with the new methodology led to insights which are the basis for the design of two new products. These new products are compared with state of the art products in [T.E. Kuhn, Solar control: comparsion of two new systems with the state of the art on the basis of a new general evaluation method for facades with venetian blinds or other solar control systems, Energy and Buildings, in press] on the basis of the new methodology.     

Illuminance-based slat angle selection model for automated control of split blinds

Venetian blinds play an important role in controlling daylight in buildings. Automated blinds overcome some limitations of manual blinds; however, the existing automated systems mainly control the direct solar radiation and glare and cannot be used for controlling innovative blind systems such as split blinds. This research developed an Illuminance-based Slat Angle Selection (ISAS) model that predicts the optimum slat angles of split blinds to achieve the designed indoor illuminance. The model was constructed based on a series of multi-layer feed-forward artificial neural networks (ANNs). The illuminance values at the sensor points used to develop the ANNs were obtained by the software EnergyPlus™. The weather determinants (such as horizontal illuminance and sun angles) were used as the input variables for the ANNs. The illuminance level at a sensor point was the output variable for the ANNs. The ISAS model was validated by evaluating the errors in the calculation of the: 1) illuminance and 2) optimum slat angles. The validation results showed that the power of the ISAS model to predict illuminance was 94.7% while its power to calculate the optimum slat angles was 98.5%. For about 90% of time in the year, the illuminance percentage errors were less than 10%, and the percentage errors in calculating the optimum slat angles were less than 5%. This research offers a new approach for the automated control of split blinds and a guide for future research to utilize the adaptive nature of ANNs to develop a more practical and applicable blind control system.     

Window blind occlusion: a pilot study

Estimations of daylight factors, used to calculate energy savings, typically do not consider occupants' use of window blinds. The data indicate that such estimations should include some assessment of window blind usage, because over half of the window area is usually occluded in some way by blinds. It appears that many occupants purposely use window blinds to prevent sunlight from penetrating their working space.
