How to Borrow Light | Bedford Real Estate

In 1915 the 38-story Equitable Building in New York City was the largest office building in the world. Containing 1.2 million square feet of office space, it consumed nearly every available square foot of its diminutive lot and cast an equally large shadow on its neighborhood in lower Manhattan. Its construction inspired the enactment of the city’s 1916 Zoning Resolution, which was designed to preserve access to light and air at the street level. The resolution prescribed specific limitations for a building’s envelope — its outer walls — and would go on to shape the stepped forms that you see today on many of the iconic towers in the city.This underscores the importance that access to daylight had in shaping even the largest of cities, the individual buildings that make up those cities and, more broadly, sensible building design. With an increasing focus on sustainable design practices, the smart use of natural daylight in our homes is no longer a luxury — it has become a necessity. At the heart of any good daylighting strategy is a concept of “borrowed” light: the capture of light falling on the exterior of a home and transporting it to the spaces where it’s needed.
