The skyscraper has evolved as an economically efficient way to provide flexible, functional and well-illuminated workspaces for dense populations of professionals. Since the early 20th century, however, air conditioning and electric lighting have served as modern solutions to increasing demand without giving thought to environmental consequences or energy shortages.
Today the skyscraper needs to evolve into a new sustainable species. It must retain highly developed qualities such as flexibility, daylight, views, density and general usability while exercising new and untested attributes. Seen from the city SEM will appear as a classic shape with an organic pattern. A folded curtain wall shades the building from the sun and creates a comfortable interior climate. The folds create special niches and unique spaces inside the office floors as well as on street level around the building.
The traditional curtain wall glass façade has a low insulation level and leaves offices overheated by direct sunlight. The result, excessive air conditioning consumption for air conditioning as well as the need for heavy glass coating that makes the view seem permanently dull and grey.
By combining maximum daylight exposure with minimal sunshine exposure and using integrated ways of limiting the need for cooling SEM serves a model for the 21st century skyscraper and energy headquarters.
