The advent of sustainability and Energy Efficiency ushered in technological innovations in building energy management (BEM). It led to increasing research focus on green building technologies (BEMTechs) for Built Asset Management, and a corresponding shift in public and private sectors’ strategic direction and perception of smart building technologies (Tanneja, 2014). The adoption of installation of intelligent building’s technology as Building Energy Efficiency intervention is now the norm worldwide. Building energy management system (BEMS), are deployed to help monitor and control installed Heating, ventilation and air conditioning equipment in modern buildings. Also, trending is the adoption of renewable technologies (RETOs) and low carbon interventions as cleaner energy production in commercial buildings (Yumldella, 2012). The use of solar photovoltaic (PV) panel in a building may not reduce its energy use but could reduce its CO2 emissions. Past studies (Bugaje, 2006; Olawuyi, 2013) demonstrated the usefulness of low-zero carbon (LZC) interventions as the best methods of GHGs emission reduction, improves Building Energy Performance, guaranteed energy access and security, and climate change mitigation.
