Older, inefficient commercial rooftop unit (RTU) air conditioning systems are common and can waste from $1,000 to $3,700 per unit annually, depending on the building size and type. By replacing or retrofitting them, you can save money, improve your energy efficiency, make your building more comfortable, and help the environment. The Advanced RTU Campaign (ARC) encourages commercial building owners and operators to replace their old RTUs with more efficient units or to retrofit their RTUs with advanced controls in order to take advantage of these benefits. This website shows updates to the campaign including resources and progress towards the campaign's goal.

The Energy Management Package was developed by LBNL and DOE to deliver energy management and low- and no-cost energy efficiency opportunities to the small commercial building sector (less than 50,000 sq. ft.). This whole-building efficiency service offering was designed to be delivered by HVAC contractors at low transaction cost, and includes analysis of whole-building monthly or interval energy data and benchmarking, using free and low cost software tools. The website includes links to the Package itself, the business model associated with delivery of the Package, an introductory webinar, and an overview slide deck. Contractors servicing the small commercial sector who are interested to help demonstrate this approach should contact the point of contact below.
The package helps contractors to address questions such as:
What no- or low-cost measures could generate savings in a building?
How much energy does a building use compared with similar buildings?
How has energy usage changed over time? If the owner has already made upgrades, have they been effective?
How much money could potentially be saved through energy upgrades?
