The Turner Group has a strong belief in high performance design. This can range from simple items to more elaborate items. A simple item such as walk-off mats that will remove debris from occupantÃ¢â‚¬â„¢s shoes will save on cleaning costs and improve the overall air quality of the building. A more elaborate system is a geothermal heating system with a solar component to preheat water and collect photovoltaic power. The Turner Group has been providing high performance buildings for nearly two decades; prior to a point based rating system. Our firm is able to work with you to find the right sustainable system that will fit your project needs.
