My LEED idea for my house project was water efficiency. Unfortunately I couldn't find any water pumps on revit city that actually fit the idea I was going for, The water pumps would have been in the basement and would have pumped the water from the near by river towards the front of my house. It would also heat the water and supply all the washrooms and the kitchen throughout the house. I choose this LEED example because I though it would be cool to use a water resource near your house. Since I built the house in such a weird area and it would have been expensive to get water from a city all the way out there using the river in front of my house I thought would be a good idea.
