MCR DIVA for Grasshopper life cycle cost analysis Matthew C Rheingans

Life cycle cost analysis for an existing building using DIVA for Grasshopper as part of Parametrically Optimized Sustainable Facades. My group identified an existing structure in the Harvest Mission Church in Ann Arbor as having potential for a more sustainable façade. The building has large concrete walls and minimal windows. We limited out intervention to the south façade and the roof. Using Grasshopper to parametrically control window to wall ratio, louver angle, insulation thickness, and glazing type. Then using the material properties, and the standard cost of these materials we found the initial cost of materials and using energy simulation the operational impact. Using Galapagos’ evolutionary solver we were able to optimize these costs over a 30 life cycle of a building to find the most sustainable façade in terms of life cycle cost.
