Chapter 1: DESIGN PROCESS
Summary
This chapter addresses the design process, during which mechanical and electrical systems and equipment are considered, selected, evaluated, sized, and integrated into a building. The design process includes identifiable phases, generally termed pre-design, conceptual design, schematic design, and design development. The construction and occupancy and operations phases follow design. Building commissioning is an emerging process being used to provide quality assurance to the design and construction endeavors.
Design intent and design criteria are emphasized as critical to successful design. Design hypotheses must be validated through analysis, using a range of methods and tools. Built projects can be assessed using post occupancy evaluation techniques. Case studies are being used both as examples and as a framework for building evaluation. The influence of codes and standards, and costs (first and life-cycle) is discussed.
Passive, active, and hybrid solutions to design problems may be implemented. The differences between energy-efficient, green, sustainable, and regenerative design are explored. A philosophy of design espoused by John Lyle is summarized; this philosophy suggests: Letting nature do the work, Considering nature as a model and as a context Using aggregating solutions rather than isolated solutions Matching technology to the need at hand Seeking common solutions to disparate problems Shaping the form of systems and buildings to guide the flow Shaping the form of systems and buildings to manifest the process Using information to replace power Providing for multiple pathways, and Managing storage to match needs with resources.
The Gilman Ordway Campus of the Woods Hole Research Center in Falmouth, Massachusetts is provided as a case study of design process for a green project.

Key Concepts
The Absolutely Constant Incontestably Stable Architectural Values Scale (intriguing) design process (a multi-stage flow of information, ideas and decisions) design values (as critical to intentional design) design intent (as the starting point for design solutions) design criteria (as benchmarks for design intent) design validations (as critical to good design outcomes) design process influences (codes/standards, first costs/life-cycle costs) building evaluation (as a learning and verification process) post-occupancy evaluation (POE) case studies (as an emerging design tool) passive/active design approaches (as fundamental options) energy efficient vs. green vs. sustainable vs. regenerative design (important to distinguish) John Lyle design philosophy (as worth of consideration) Woods Hole Research Center, Gilman Ordway campus (a green building example) AIA/COTE Top Ten Green Projects Award
