The "Whole Building" Design ApproachGoal: to create a successful high-performance building.

Strategy: Apply an integrated design approach during the planning and programming phases, e.g Involve all stakeholders in the design processThe ownerDesign TeamBuilding occupantsConstruction ManagerOperation & maintenance personnelGovernment agenciesCommunity Groups

Act on the premise that all building systems are interdependent e.g., modeling the building using all available simulation tools

2The "Whole Building" Design Approach The goal of 'Whole Building' Design is to create a successful high-performance building. To achieve that goal, we must apply the integrated design approach to the project during the planning and programming phases. It is necessary for the people involved in the building design to interact closely throughout the design process. The owner, building occupants, and operation and maintenance personnel should be involved to capture their understanding of how the building and its systems will work for them once they occupy it. The fundamental challenge of 'whole buildings' design is to understand that all building systems are interdependent.

The Basic ConceptRecognizing that buildings: are complex consume vast amounts of energy and material resources over their life time

The 'whole buildings' design approach is: a collaborative effort a comprehensive evaluation and modeling of materials, systems and assemblies for: costquality-of-lifefuture flexibilityEfficiencyoverall environmental impactproductivity and creativity how the occupants will be enlivened

3The Basic ConceptBuildings are deceptively complex. At their best, they connect us with our past and represent our greatest legacy for the future. They provide shelter, encourage productivity and embody our culture. But they also consume an extraordinary share of America's energy and material resources. In the past, we have addressed this issue by analyzing the individual components and subsystems of each building and optimizing them separately.The 'whole buildings' design approach asks the members of the planning, design and construction team to look at the materials, systems and assemblies from many different perspectives. The design is evaluated for cost, quality-of-life, future flexibility, efficiency; overall environmental impact; productivity and creativity and how the occupants will be enlivened.

LEED Vs. MSBGWhat is LEED?The LEED Green Building Rating System, developed by the USGBC, is the only nationally recognized green building rating system. LEED evaluates the performance of buildings from a whole building perspective, over the course of a buildings lifecycle, which provides a definitive standard for what constitutes a green building.

Sustainable BuildingSustainable architecture is foremost about reimagining the relationship between human beings and living systems. The most powerful expression of this is our built environment. Today, architects must work with systems; they must design new ways of living and working in which buildings play a key role. __Paul Hawken from the preface to Sustainable Architecture White Papers
