1. Executive Summary:
This energy audit is done by the students of USPCAS-E UET Peshawar at Unsere Kinder
School. Unsere Kinder School is the realization of the GIS System in the full sense. It
combines the values of premium education with the latest innovation in technology to
deliver the best-of-the-breed curriculums to Children from Age 2 onwards.
Energy Consumption is primarily a major concern all over the globe, and saving energy
and finding opportunities for energy conservation is better than generating energy.
The operations of buildings account for 30% of global final energy consumption and 26%
of global energy-related emissions (8% being direct emissions in buildings and 18%
indirect emissions from the production of electricity and heat used in buildings).
Considering such threats, the world is shifting towards Green Buildings and Net-Zero
Energy Buildings. In this regard our main focus is to target educational buildings, to
make them energy efficient and environmentally friendly buildings by the process of
energy auditing (energy performance assessment) that includes Energy Consumption
analysis, calculating energy consumption by different kinds of loads (Lights, Fans,
Motors, HVAC), Identifying potential areas for improvements and recommending
Energy Efficiency Measures (EEMs) along with techno-economic analysis. This project
aims to cover three main SDGs that includes Quality Education (SDG 4), Affordable and
Clean Energy (SDG 7), and Sustainable cities and Communities (SDG 11).
This energy audit report:
• Evaluate overall energy consumption
• illustrates current energy use
• identifies and outlines potential areas of energy and cost savings.

Energy Consumption:
The major part of the energy is covered by electricity consumption in unsere kinder schools.
Electricity is consumed directly from the main grid and in addition to that PV system is installed
for onsite generation. And the connected meters are Three Phase Smart Meters. The overall
energy consumption and onsite generation by PV system are as below.
