Climate change is increasing the average temperature of world due to emission of
greenhouse gases (GHGs) in large amount. This has increased the annual energy consumption of
buildings. These energy demands are fulfilled by non-renewable energy resources mostly. The
infrastructural development in the fields of educational buildings, hospitals, industries, etc. is
necessary requirement for growing country like Pakistan. The building sector of Pakistan
consumes approximately 50 % of country’s total energy. To reduce the energy consumption of the
buildings, different passive climate adaptation measures (PCAMs) can be implemented. In this
study, several low-cost and medium-cost passive measures and their combinations were applied
on the building model. This study analyzes their effects on annual energy consumption of the
educational buildings in Pakistan. Energy simulations were performed by implementing these
passive measures using DesignBuilder. The result shows that 2 °C variation in temperature
setpoints and green wall are the most effective passive measures for reducing the annual energy
consumption of the building. The implementation of these passive measures can reduce the cooling
and heating energy consumption by 27.18 % and 62 % respectively. The energy use intensity (EUI)
of the SMME building was 154.71 kWh/m2
/year which is higher than EUI requirement for
buildings. Furthermore, the payback period of each passive measure and their combinations was
also calculated. Variation in temperature setpoints can reduce the significant energy consumption
with a zero-payback period. Finally, the cost benefit analysis was performed to suggest some lowcost and medium-cost passive measures.
