More comfortable, more attractive… with less energy.


A handsome 18-floor office building in downtown Birmingham, Two North Twentieth was built forty years ago to provide attractive office facilities in the heart of a city rich in diverse architecture, landmarks, and parks. Owner George Cornwell wanted to refurbish the building in order to return it to its position as a leading office location. Additionally, he hoped to reduce the building’s substantial energy costs.


Cornwell retained the services of architect Donald Simpson of KPS Group of Birmingham and Evergreen Construction, a prominent construction company in Atlanta. After lengthy research into a wide range of window films, the architect chose to install 30,000 square feet (2,787 square meters) of LLumar R-20 SR CDF window film; a film that would give the building a modern, prestigious look while rejecting 79% of the solar energy entering the room.


In the process of creating a more comfortable and attractive place to work, Cornwell saved money on energy costs. “This was an important first step in our goal of bringing Two North Twentieth into the 21st Century,” architect Donald Simpson said.

LLumar window tint is professionally installed by trained technicians and is backed by a lifetime limited manufacturer’s warranty.
