As part of this Transactional Network initiative, Building Technologies Office BTO has funded Pacific Northwest National Laboratory (PNNL) to develop an open source, open architecture platform that enables a variety of site/equipment specific applications to transact in a cost effective and scalable way. The goal of this initiative is to lower the cost of entry for both existing and/or new service providers because the data transport or information exchange typically required for operational and energy-related products and services will be ubiquitous and interoperable.
