Parameters considered for selecting cities:

• Parameters agreed in with IDEAM considering complex geography of the country.

• Construction activity & market trend• Climatic zones – Height above the sea level is the main factor which

characterizes cities’ climate.

Good Practices

+

Understanding Building Physics: There is a need for design

professionals to revisit the principles of building physics while

designing buildings.

Revisiting Building Physics

+

The code has been designed to avoid resorting to expensive building

energy/water modelling tools. Most guidelines are simple and prescriptive.

Modelling Tools

+

Opportunity for a new design language: An active engagement with

the environment helps in creating a refined language of architectural

aesthetics.
