Green features of the facility

From the get go, we have been insisting with our architect that our facility ought to be green but cost effective.  Our architect being an expert in the cost effective construction took up the challenge to come with the features that we are delighted to describe below:

• Rat Trap Walls: Compared to the conventional laying of bricks for the wall building, they lay them in a particular position where it creates an empty space between the bricks that acts as an insulation for the temparatures (Yes, our town fluctuates to the extremes between 20 and 40 degrees of celsisus)
• Filler Slab: According to our architect, entire roof doesn't have to be concretized like in the conventional roof because there are spots in the which has no value of any kind.  That means what he is saying is that one can fill that space which has no value of any kind with anything that one likes.  Our architect simply fills up such space with used tiles that are available for as little as two rupees a piece.
• Breathing bricks: When the bricks in the wall are plastered with cement on both sides, according to our architect, shuts the porous properties of the bricks that allows them to breath.  So our architect leaves the walls without plastering them so they breath and in turn they keep the facility temparature inside higher or lower depending on the season.
• High Courtyard: Building designers (EMI2 architects) gave a high and open courtyard (in the middle of the building) that enables the hot air inside the facility to escape to keep the building cool in the summers.

Apart from these features in the construction (that I consider them to be active features), we would like to engage passive features (by harnessing solar and wind energy) to make this facility even more environmentally friendly.
