A Guide To Energy Efficiency Ratings For Commercial Heating Systems

In the USA, commercial buildings account for a massive 19% of the total energy consumed in the country – primarily for heating/cooling and light – with office, retail, educational and healthcare buildings at the top of the list for consumption. One of the most significant opportunities for commercial buildings to reduce their consumption – and therefore their running costs – is the implementation of energy-efficient HVAC systems. Here’s a quick guide to energy efficiency ratings for your heating system or boiler system from commercial heating systems specialists. Energy-Efficiency Regulations for Commercial Heating Systems and Boiler Systems In heating systems, efficiency is measured by Annual Fuel Utilization Efficiency (AFUE), which measures how effective the equipment is in converting fuel into heat. In a 90% AFUE commercial boiler, for example, 90% of the fuel consumed by the boiler is turned into heat, so the higher the rating, the more energy-efficient t...
