I want to focus on three topics; sustainability and how to reduce emissions from buildings or the material choice for more sustainable design or talk about how BIM/ AutoCAD has helped to reduce the construction industry carbon footprint
Why not look at designing a building that has a zero carbon footprint?
1.) Pumping of water requires a lot of energy, usually 20-30% of society's electric and gas use--so put a water catchment system on every rooftop, to be used for flushing toilets and outdoor watering. The catchment system will also act to shade the roof, so that less will be needed to cool the building in summer.
2.) Calculate the lifespan of a building, usually between 60 and 100 years, calculate how much energy it will need to cool, heat, and light over that lifetime, and buy carbon credits to produce a carbon-neutral building--and make that part of the selling price of the building.
3.) On the roof install solar panels, and that will do two things--shade and cool the roof and lower the need to cool the building in summer, at the same time, provide carbon neutral electricity.
4.) Install double the insulation in the roof and walls, to conserve on cooling and heating.
5.) Drill a "cooling well", to draw cold air up from underground, to use to cool the building in summer. I saw this built into a building near Reno, so very little electricity was needed to cool the building with additional air conditioning.
