Programming should begin with a clear definition of the work activities to be performed. Accounting for functional needs is a primary purpose of the planning process that defines an owner's functional and physical requirements for each spatial element in a building or facility. This process seeks to state the problem; establish goals; collect and analyze facts; establish functional relationships; uncover and test concepts; and finally state the problem to direct a course of action. Adequate programming performed in the project planning phase will clearly delineate functional requirements and relationships of occupant activities and spaces required for all supporting building systems and equipment. See WBDG Architectural Programming for a more detailed explanation of how architectural programming helps the project team achieve a well functioning high performance building.

However, a truly functional building will require a thorough analysis of the parts of the design problem and the application of creative synthesis in a solution that integrates the parts in a coherent and optimal operating manner. 'Whole Building' design is characterized by a design solution that functions well from an occupant activity and building systems point of view.

There are several key steps in the development of project requirements that fully describe the design problem. They are:

• Understand how the work processes support the mission and purpose of a facility;
• Define spatial requirements for occupant activities and equipment;
• Understand functional relationships among the programmed spaces;
• Anticipate installation, Operations & Maintenance (O&M) practices, spatial change, and replacement of building equipment;
• Accommodate information technology (IT), communication, and other building systems equipment; and
• Consider serviceability (clearance) requirements.

Effective programming will include all pertinent stakeholders to ensure "Whole Building" functions have been identified. Conducting programming and design charrettes with these stakeholders is an effective means of enhancing integrated functionality and mutual agreement on a design approach.

Recommendations

Understand How the Work Processes Support the Mission and Purpose of a Facility

• Determine facility use, occupancy, and activities to be housed.
• Balance the owner's needs and goals for space, quality, budget, and time.
• Set owner's design objectives in the early planning stage.
• Reference building type guidelines. See also WBDG Building Types.

Define Spatial Requirements for Occupant Activities and Equipment

• Consult all pertinent stakeholders for their requirements.
• Consult planning guides and specialists on programmed activities.
• Document all regulatory requirements, such as building codes, accessibility laws, ATFP, etc.
• Explore the possible necessity of making spaces flexible to accommodate changes in business practices, work activities, and technologies.
• Consider building operations and maintenance activities in the design of spaces.

Understand Functional Relationships Between Program Spaces

• Engage user groups in facilitated discussions to brainstorm solutions.
• Examine patterns of activity in facility program and consider how those patterns create spatial relationships.
• Account for physical security requirements in the layout of space planning.
• Consider impacts of building systems and engineering needs on spatial relationships in both occupied and unoccupied spaces.
• Leverage opportunities for quality environmental aesthetics such as natural light, spatial volume, views, texture, and materials. See also WBDG Aesthetic Opportunities and Aesthetic Challenges.

Anticipate Installation, Operation, Spatial Change, and Replacement of Building Equipment

• Incorporate structural and mechanical systems as integral parts of early design concepts.
• Account for structural loads (dead and live) of building systems and equipment.
• Ensure that mechanical system equipment and furniture, fixtures, and building equipment (FF&E) can actually be installed, operated, and replaced.
• Consult facility O&M personnel in the programming and early design stage.
• Plan infrastructure for flexible spatial modifications or "churn".

Accommodate Information Technology (IT), Communication, and Other Building Systems Equipment

• Determine the owner's goals and needs for spatial and mechanical support of the organization's IT program.
• Incorporate IT system needs as an integral part of the design concept.
• Design for configuration flexibility within workspaces that promotes occupant productivity. See also WBDG Accessible—Plan for Flexibility.
• Accommodate network support and servicing requirements in the design of spaces.

Vontz Center for Molecular Studies—Cincinnati, Ohio. This 150,000 gsf., $35 milllion interdisciplinary research center is designed to accommodate neuroscience and cancer research. It includes core science research labs, offices, support areas, and seminar rooms with fully accessible mechanical, electrical, and support spaces between the main laboratory floors.

Consider Serviceability (Clearance) Requirements

• Design for vehicular clearances in the site design (e.g., drives, gates, ramps, parking).
• Design for vehicular clearances in building design (e.g., doors, docks, obstructions).
• Design for proper equipment access for maintenance and removal and replacement of equipment and/or major components, such as filters, boiler tubes or piping.
• Design for durability.
• Design for maintainability (including housing of maintenance equipment).
• Consult facility O&M personnel in the design process.

Emerging Issues

• Computer-based space programming applications
• Appropriate accommodation for the changing nature of work (productivity)
• Virtual workplaces and increased use of "Hoteling" for flexible space
• Building Information Modeling (BIM) (defining object functionality for facility life cycle)
• Adaptability for possible change of building needs and function over time.
