Energy Lens Software Used to Determine the Energy Usage of an Academic Building in a Tertiary Institution in Nigeria

Abstract

The energy audit has its prime objective which is to evaluate a building’s energy usage hence,   recommend various energy management solutions that can satisfy increasingly demanding requirements of the power systems concerned. In historical building, with high energy consumption trends; decisions must be taken quickly to achieve rapid restoration of reduced energy usages and return of normal energy consumption condition with respect to the occupant behaviour or other energy audit abnormality. This study intends to explore the energy consumption within the month of August 2018 using Energy Software called Energy Lens. These techniques should recognize the existing occupants’ behavioural characteristics in the building from using their appliances and lighting. The use of Energy Auditing software such as Energy Lens helps in assessing a wide range of different building types and environmental performance approach. From the analysis, the total energy consumption from the period of 1^st august 2018 to 31^st august 2018 was determined from the Energy Lens software to be 13,545kWh energy consumed. Heat loss of building (Q_loss) was calculated as 12.905W, the Building design heat loss (H) was calculated as 3.226W/K and Total ventilation heat loss (Q_vent) was calculated as 13,994.7W.
