Abstract
Climate change has been a global catastrophic event and being an agriculture dependent country
Pakistan's vulnerability to this change is quite high due to geographical location. In the past decade,
numerous irregularities like extreme weather spells, floods, glacier lake outbursts, and heat waves
have been observed. Global Climate Index has ranked Pakistan as the fifth vulnerable country
towards climatic change (Business Recorder, 2021). Rather than referring to as one of the most
vulnerable countries to climate change, it would be more accurate to be referred to as least
prepared. Sustainable ideas and concepts that have been practiced throughout the 20th century
require a new resilient approach towards energy conservation and efficient energy houses for the
adaption of ongoing/new environmental changes. Billions of rupees have been spent on building
new houses each year. It is a very little known fact that implications of passive house techniques
such as insulation may reduce the energy consumption hence reducing the overall running cost.
With little understanding, upfront costs associated with energy-efficient building envelops have a
huge negative economic impression on residential units and residents may end up having huge
operations and maintenance costs for a lifetime by opting for standard brick envelopes. Therefore,
the purpose of this study is to assess the lifecycle cost and payback time for energy-efficient
building envelopes.
