additional innovative daylighting strategies: • light shelves have a dual purpose,
providing shade and indirect lighting – light bounces off the reflective surface of the shelf onto a ceiling, which bounces it into the room thereby increasing the amount of daylight penetration.
• light-pipes collect light through a heliostat located at the rooftop, and channel it through a reflective tube of prismatic glass or mirrors. At the end of the light pipe, diffuse light is distributed within the space.
• anidolic ceilings use parabolic concentrators to collect diffuse daylight which is distributed to the back of a room through a specular light duct located above a ceiling plane.
• Venetian blinds with a reflective upper surface may be used to reflect the sun’s rays onto a light-coloured ceiling to provide diffuse lighting in the building’s interior.
• translucent materials may be used in place of glass to admit diffused light into a space with no direct sun.
• solar bottle bulbs made from plastic bottles filled with water and
encased in a galvanised iron sheet provide an environmentally friendly daylighting solution to houses with non-existent or typically small windows as in the case of informal settlements.
glazing ratio The larger the glazed area, the more daylight and heat gain will enter – but the larger the heat losses will be. (...) Tinted or reflective glass reduces solar heat gains but limits the amount of visible light.

They were constrained by budgets, geography – the site is a narrow strip bound by roads and a railway between existing buildings – and the need for an efficient, energy-saving work environment that catered to the needs of its staff.
Aluminium, glass, stone and concrete are the main building materials used in a delicate compromise between maximum light penetration and optimal heat retention or cooling. (...) One of the innovations of the building’s Modernist architecture was the inventive manipulation of natural light, which floods the interior then is reflected off the spacious light grey walls of the central core. The interior office walls are made of glass, cutting down on harsh artificial light. The lighting system operates through a series of sensors that react to movement within a given space; the energy allocation is further adjusted to take account of available natural light, giving balanced and consistent illumination at lower cost.

Other methods include internal shading devices e.g. curtains, blinds etc. and the glass itself e.g. low emissivity glass tinted glass.
(...) They are desirable for providing effective shading for the floor level directly below them at the peak point of the day. The amount of light admitted into the room, and the length of the shade is dependent on the depth of the overhang. (...) Nairobi

Other shading strategies
Design the building to shade itself
The form of the building itself can be used for external shading.
• The use of deeply recessed windows makes the entire wall around the opening an effective shading device, minimizing solar heat gains without reducing natural light and view (fig. 06).
• A cantilevered floor can be used to shade windows on the level below it.
• Windows on the east and west facades can be oriented north or south for sun control (fig. 07).
• Use of inclined glass is effective in controlling the penetration of the solar radiation into the building by reducing the area of glass exposed to the sun.
