PNC Group shows off green patch on company wall to be energy-efficient

Wall ads and billboards are one of the most attractive features of advertising especially for drivers. PNC Financial Services Group felt that they needed to get some attraction while also giving their employees the chance to boast working in an eco-friendly, energy-efficient environment. They built a plant-covered exterior wall to make their point which is “to make its headquarters building more energy-efficient”. This patch of green on its wall features a variety of regional plants and designers have estimated that it will be cooler behind the wall and helping cut the air conditioning load during summers. Whatever may the reason be, they made an effort in doing something green and that is a small step towards saving the world.
