Description: When evaluating the instantaneous rate of solar heat gain through a window, it is essential to know the shaded area, if any, of the glazing. This is a typical standard drill, which is frequently carried out for conventional windows, which have the glass panes parallel to the building exterior wall. Sometimes, and for architectural or other reasons, the glass may be fixed in a vertical but horizontally rotated position; i.e. non-parallel to the wall. This may help to rationalize the energy requirements for air conditioning. The objective of this paper is to establish a systematic method to calculate the sunlit, and hence the shaded, fraction of slant-glass area. The presented analysis takes into account all of the numerous variables involved in the problem; namely, location, date, time of the day, wall orientation, rotation of glass relative to the wall, and geometrical characteristics of the window. The calculation procedure is casted in a general computer program which can be readily and unlimitedly used for any set of conditions. Some sample results are presented. (10) One River Terrace (Battery Park), NY Colt shading systems have made a contribution to this achievement. Around the top level plant room Colt has provided a series of architectural louvers to generate electrical power. These comprise Shadometal perforated metal architectural louvers to the north elevation, and movable and sun-tracking vertical Shadovoltaic pv solar panels to the south, east and west elevations. These pv solar panels provide just over half of the building's 70 kWp electricity that is generated from photovoltaic cells. Furthermore, the movable louvers are controlled by a passive Girasol sun tracking system that is entirely autonomous. SEW Eurodrive, Karlsruhe, Germany The new training and development centre in Karlsruhe is a stunning and unusual shaped building, and thus presented a challenge for the design of a suitable solar shading system. The design team were confident with the Colt proposals and track record, and accordingly Colt was chosen to provide a Shadometal perforated movable vertical solar shading system, controlled by the Colt ICS 4-Link control system which tracks the sun’s position and automatically sets the position for the louvres.
