Reduced Energy Loads: approx. 70% of lighting energy is saved in areas where daylightingis employed. In addition, electric lamp replacement and cooling loads are reduced.
Increased Productivity: Worker productivity has increased
Reduced absenteeism: Workers remain more alert, and are absent less, under natural lighting conditions.Simple Payback: 5.9 years

WMP found it difficult to explicitly:
Propose many options
Analyze these options
Compare their analyses to their goals
Clearly communicate this design process
Quickly integrate this design process

What is a methodology that enables AEC professionals to formalize the dependencies among their representations, and control the integration of these representations as the project progresses?
Research Question
Problem: The narrative structure is not formalized or managed.
Result: AEC Projects are not achieving sustainable balance.
