Energy Savings Case Study


K&N Office Limited Partnership owns and manages commercial office buildings and apartments throughout the United States including The Nashville House - a 150,000 sq. ft. office complex consisting of 5 buildings, 4 stories each in Nashville, TN. They wanted to lower their energy usage without making load changes or interfering with the daily operations of their facilities and hired EIS to create an engineering design to see how much savings could be achieved within the goal of 36 month payback period. Pleased with the projected savings and a guarantee underwritten by Lloyds of London, the Nashville House then hired EIS to complete the installation, which took 45 working days.
