                      CONCEPTUAL AND SCHEMATIC


                      DESIGN















                      In the conceptual and schematic design phases, the high-performance design team typ-
                      ically investigates major systems alternatives for the project, looking at free natural
                      resources such as solar, wind, and geothermal; climate control schemes; façade alter-
                      natives, building, massing, and orientation on the site. At this stage, the team can make
                      some “back of the envelope” calculations of energy use and energy savings alterna-
                      tives. The team can make a rough stab at costs, but doesn’t know enough for detailed
                      cost estimates. By the end of this phase, the team should know quite a bit about major
                      building systems, pending detailed analyses in the design development phase, along
                      with further costing and constructability reviews.
                        I cannot overstate the importance of considering sustainable strategies during these
                      two phases; the entire reason for the questions posed in Chaps. 9 through 13 is to avoid
                      overlooking good ideas in the rush to “do something.” One authoritative text on
                      schematic design puts it this way.*

                        During conceptual design, the owner is convinced that the design team has a vision
                        worth pursuing. During schematic design, the design team convinces itself that the
                        vision sold to the owner is in fact feasible. Rarely do any big ideas creep into the
                        design process after these initial phases.

                        In other words, every project starts out with a degree of trust, first on the part of the
                      owner, that the team is up to the job. During the next phase, the team demonstrates that
                      it can in fact implement the original project vision, or that it has to alter the vision
                      owing to new discoveries: about the site, the stakeholder interests, the available
                      resources, money, and so on. Once a specific design direction is chosen, almost noth-
                      ing short of a major upheaval (such as a change in owners or owners’ interests) will
