Waste reduction directly correlates with reduced energy consumption and carbon generation. Indeed, IBM asserts that IT and energy costs can account for up to 60% of an organization's capital expenditures and 75% of operational expenditures.  In this way, identification and streamlining of IT value streams supports the measurement and improvement of carbon footprints and other green metrics.  For instance, implementation of Lean IT initiatives is likely to save energy through adoption of virtualization technology and data center consolidation.  
Excellent buildings have become the exception not the norm and although this may be due to a litany of external factors; it is also due in large part to our professional fixation with the purely formal qualities of buildings and spaces often to the exclusion of their dynamic situations over time, the spectrum of activities they enable, the overall goals of the client, the resources they require to build and maintain, and their ability to adapt, change and improve over time. These shortcomings present a clear and immediate challenge to re-evaluate traditional practices and find innovative methods to measurably improve design quality.
