Energy modeling education lines up perfectly with the conference theme of "Scalable Solutions." Currently, a typical large project design process would rattle through the different disciplines in the order of: Site/Civil, Architectural, Structural, Plumbing, Mechanical, Electrical, Fire-protection then finally construction. Today energy modeling is done by the mechanical engineers - at one time - in the middle of the design process. Too far along to make any significant changes which could provide unparalleled energy savings. At this point energy modeling is used primarily for sizing mechanical equipment. Where it could be used as a decision making tool. Shifting walls, moving windows, adjusting materials in the envelope assemblies, and simplifying the exterior shape of the building are examples where architectural decisions can significantly reduce heating and cooling loads in a building. In developing the stock net zero designs of BTF - we discovered how much of an impact energy modeling can make. Especially when referenced in the architectural design phase. In our initial design experiments we created an ideal energy model first. Using that model we then developed architectural designs that matched it. We designed in the opposite of common practice. Switching the order from running an energy model only after a complete architectural design - to designing from the model itself. While this may be more complicated than the industry is ready for, it did shed light on the significance that energy modeling can play. And that each of the disciplines, not only mechanical, can make better informed decisions by using energy models. As it is now, energy modeling is often learned on the job. And very limited is the nationwide resource of designers and engineers who can perform accurate energy models. There is simply not the available manpower to develop energy models for many multiple iterations. For us to make significant change in the energy demands of our buildings we can not rely on expensive high end materials, but we must design efficient shapes and assemblies too. We need to support and empower a larger network of energy modeling based decisions. To do this we must simply share the tools and education for everyone to develop basic energy models in house.
