In the present work, it has developed algorithms for embedded software and hardware devices, associated with microcontrolled and microprocessor platforms, with the purpose of achieving smart building convergence in lighting and energy metering systems without automation, communication and control features. To do so, the approach described in the SmartLVGrid framework is used, a model that uses the retrofit strategy for convergence in intelligent low voltageelectricpowerdistributionnetworks.Thisframeworkwillbeadaptedtoperformbuilding automation at the Embedded Systems Laboratory of the HUB research and development center, associated with the Escola Superior de Tecnologia of the Universidade do Estado do Amazonas. The obtained results indicate the possibility of the smart building convergence without total removal or disposal of the lighting and energy metering systems on site through the retrofit technique, resulting in low implementation costs and fast process of technological transition. ThelightingcontroldeviceswerebasedontheDC-DCconverterBuckLowSideassociatedwith a microcontroller with built-in wireless communication peripherals, allowing the device to be remotely controlled. The energy measuring device has circuits for measuring, conditioning and protecting the system. It also has a microprocessor platform with Linux operational system and integratedcommunicationperipherals.Withtheresults,discussionsandconclusionsofthiswork, it is expected to contribute to a robust and easy implementation method, capable of achieving smart building convergence, with the increase of energy efficiency.
