Heat Recovery : Heat recovery ventilation is a ventilation system that employs a counter-flow heat exchanger between the inbound and outbound air flow. HRV provide fresh air, while saving energy by reducing the heating (or cooling) requirements. The system helps to improve the Indoor air quality of the building, thereby offering health benefits to the human within the building.

Daylighting : Daylighting is the practice of placing windows, or other openings, and reflective surfaces so that, during the day, natural light provides effective internal illumination. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use. Energy savings can be achieved either from the reduced use of artificial lighting or from passive solar heating or cooling.
