Abstract
This paper presents an estimate of the level of energy efficiency that could be achieved through improvement in building envelope. A residential flat in Thimphu, Bhutan was simulated in transient simulation software TRNSYS with measured weather data. From the simulation, it was observed that the thermal energy demand of the flat could be reduced between 11-64% by insulating the building envelopes under various scenarios. The simulation result suggests that attic insulation must be the first method to look into while deciding for retrofitting a poorly performing building as it could result in a high reduction of annual heating energy demand. The simulation shows that maximum heating energy demand reduction (64%) could be achieved when attic and wall insulation was used.

Summary
The main focus of today’s energy-intensive world is energy conservation and energy efficiency. Energy conservation does not necessarily require high-end technology for implementation. With the advancement in technology, the method of energy conservation has improved. Switching off of an electric lamp in an unused room in a home is an act of energy conservation. These days, everything is possible with a mere tap on an application on the phone with the help of the concept of IoT (Internet of Things). These scientific advancements have facilitated easier conservation of energy and an efficient system that provides improved energy output with minimal losses of energy. The tradeoffs between the benefits of such technologies are required to be assessed
