EASTERN BANK

PHOTOVOLTAIC FAÇADE

 

The new corporate headquarters of the Eastern Bank in Dhaka, Bangladesh, features a slatted amorphous silicon photovoltaic glass façade which makes it more efficient and sustainable.

 

The façade, of over 500 m2, is comprised of low emissivity (low-e) amorphous silicon glass modules with a high transparency degree, fitted by means of a system of slats. This enables the uniform passage of daylight into the building while providing thermal insulation, preventing the undesired greenhouse effect within.

This glass is capable of filtering out 99% of ultraviolet radiation and 85% of infrared radiation, and features a Solar (g) Factor of between 5% and 40%, depending on the degree of transparency. A glass which enables the passage of daylight while also allowing the entry of heat, a critical factor in cities such as Dhaka, where temperatures of up to 40º are reached.

 

The façade is capable of generating 22,600 kWh per year, which makes it possible to power 1,300 lights while preventing the release of 15 tons of CO2 into the atmosphere. Its total installed power capacity is 12.5 kWp.
