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 the product is.

The Department of Energy recently issued a pre-publication Federal Register final rule that requires commercial packaged boilers larger than 300,000 BTU/hr meet a minimum of 84% thermal efficiency by 2021.

While Federal incentives seem to be on the decrease, different states and local utilities are on board with offering rebates and incentives to assist in making the move to a more efficient heating system, one example is through the New Jersey Clean Energy Program.

In this program, financial incentives and rebates are offered to industrial and commercial businesses to upgrade their heating systems, HVAC equipment, lighting and lighting controls, motors and variable frequency drives. These incentives are available to new building construction projects as well as existing buildings.  A Local Government Energy Audit is also available to determine how your building can benefit from these upgrades.
