This is the systematic approach and tools we use to deliver projects.
Retro Commissioning is the process of evaluating an existing building for the purpose of improving energy efficiency to reduce carbon footprint, reduce operating costs, and ultimately improve occupancy comfort.  A-Tec has developed a Retro-Commissioning process that brings true value to our Clients by which critical factors negatively influencing Facility performance are identified and cost effective alternatives proposed. The aim of Retro-Commissioning always being to bring about immediate building performance improvements whilst the building is occupied with minimal or no disruption to operations.
