BTL Mark Benefits

Supplier Benefits:

The BTL Mark provides two principal benefits to suppliers:

Improved Product Quality and Reduced Cost


The BACnet specification is large and complex. Even the best development teams can misinterpret some detail of the protocol or introduce a subtle implementation error. The rigorous testing associated with obtaining the right to use the BTL Mark is a powerful methodology for ensuring such errors are found and eliminated before a product reaches the market.

Resolving interoperability problems in a multi-vendor environment during BACnet system integration can be expensive and potentially discouraging for customers. In the event of an interoperability problem between a product with a BTL Mark and one without it, a common assumption is the product without the Mark is at fault. Whether it is or not, the burden of finding and resolving the problem tends to weigh most heavily on the manufacturer that has not demonstrated compliance through the BTL Mark program. Earning the BTL Mark reduces the risk of BACnet implementation errors causing interoperability problems and minimizes the associated costs.


Greater Buyer Confidence and Opportunity to Bid

The BTL Mark provides buyers with assurance that a product has passed the industry standard BACnet conformance tests conducted by a recognized, independent testing organization. This increases buyer confidence in both the product and its manufacturer, which is especially important when a manufacturer is seeking new business.



User Benefits:

The BTL Mark provides users with assurance that a product has passed the industry standard BACnet conformance tests conducted by a Recognized BACnet Testing Organization (RBTO). The tests are designed to validate that the product correctly implements a specified set of BACnet features. The specific BACnet features tested in a product with a BTL Mark are detailed in the BTL listing associated with that product. Only products that have been independently tested by a RBTO in accordance with the BTL requirements are eligible to be included in the BTL Listing of Tested Products Database.


Many building owners and control system designers have concluded that the use of products that carry the BTL Mark accelerates and lowers the cost of system integration. As such, it is becoming commonplace for specifications to require a BTL Mark in order to be eligible to bid on a project.
