whole building design green building
This CMU elevator shaft at the LEED Silver-rated Merrill Hall at the University of Washington, serves as a natural ventilation stack.

Whole Building Design is a process that views the building as a system, rather than a collection of components. The latter perspective limits significantly how sustainable a design can be, as it really only allows for a process of substituting “green” features for conventional ones.

On the other hand, viewing the building as a system allows full integration of decision making. Not only does this approach get better performance out of a building overall, it is also the best way to avoid unnecessary costs. This cost-control is directly attributable to using a systems approach to the design. Opportunities for combining functions and multiplying the benefits achieved from a single strategy are much more available with this approach.
uses

 

Concrete is a versatile material that can be used to provide many sustainable building benefits by functioning as thermal mass, acoustical barrier, durable structure. Looking at ways to combine the functions concrete is performing for a building is a way to do more with less. For example, from a wholistic point of view, an elevator shaft produced from concrete material (such as CMUs) might be viewed as ventilation shaft, a light well, and a means of controlling temperature. Besides providing integrated performance, this strategy saves money because it reduces the need for equipment.

why

Certification: The US Green Building Council (USGBC) has through consensus of its membership – primarily design and construction firms, government agencies, product suppliers, and environmental consultants – developed the Leadership in Energy and Environmental Design (LEED) Green Building Rating System. The USGBC hopes through LEED to “promote integrated, whole-building design practices.” As noted above, using the integrated design approach, higher levels of creativity are tapped, better performance can be achieved, and costs can be controlled – all worthy goals. Also, as noted above, concrete because of its versatility, can play an important role in achieving these results.

Cost effectiveness: National research indicates that a sustainable design approach should not add more than 2% to the cost of a building, and may incur none if done thoughtfully. Research also indicates that the sooner sustainability is introduced into a project, the more likely it can be achieved cost-effectively.

 

echo-charettes
Interdisciplinary teams use green design workshops, or eco-charrettes, to look at ways to integrate and optimize their design early in the process.

Whole Building Design requires a commitment on the part of the owner and design team to an interdisciplinary approach. Check-ins along the design path and during construction at regular intervals assures follow-through to this commitment. Design and construction contracts should reflect the project’s commitment to whole building design.

Whole Building Design generally means investing in design activities that increase the opportunity for integrated solutions, with an eye to better performance and life cycle savings. Integrated design activities generally include an eco-charette, life-cycle analysis, and modeling, testing, and evaluation studies.

Eco-Charettes are planning workshops that ideally occur early on in a project (no later than the schematic phase). They are the first step in an interdisciplinary design process and should include owner representatives, design consultants, and end users.
Life Cycle Cost Analysis. Typically, first cost is what designers and owners look at when analyzing whether to proceed with a specific strategy, sustainable or not. However, it is in the long period of operation that the given strategy will prove its worth. According to the Sustainable Building Technical Manual, operations and maintenance costs equal 6% of overall business costs, compared to only 2% for initial building costs (the large remainder is for personnel).

Modeling, Testing, Evaluation. An integrated design process assumes a number of building solutions will be considered and that some degree of analysis will take place to compare strategies and determine which ones are appropriate to achieve the desired performance. Modeling (simulation or physical) of daylight, energy use, water use, and air flow are methods that can be used to conduct this analysis. Costs vary with the complexity of the process used.
