Objectives:

This presentation will present a detailed technical example of high-performance, sustainable laboratory design through illustration of the approach employed and the results achieved for the design of the Twin Creeks Science and Education Center, owned and operated by the National Park Service.

It will illustrate how the intensive design processes yielded a high-performance, sustainable, laboratory facility uniquely suited to meet the objectives of the NPS. Emphasis was placed on developing a flexible research space that will accommodate changing research activities and foster inter-project collaboration among researchers. The National Park Service's adoption of the LEED™ Rating System as a design guideline will be also highlighted, as well as their implementation of life-cycle cost analysis in the decision making process. The Science Center will house research and laboratory space, curatorial space for specimens collected for the All Taxa Biodiversity Inventory, offices and educational/classroom space. The project's mission statement is as follows:

To improve protection and understanding of Park resources by enhancing science based management. This will be accomplished by creating a site sensitive, sustainable facility which fosters cross-discipline intellectual exchange, facilitates cross-organizational partnerships, enhances both basic and applied research, and encourages educational opportunities, resulting in a model for other resource based science facilities.

Findings:

The facility's daylighting strategies and environmentally responsible design features, coupled with parametric thermal modeling and building envelope optimization resulted in a building design that will consume 30% less energy than a code compliant building, while providing a healthy, productive research environment.

These results were achieved as a result of an intensive design analysis, which found that certain design features would yield a higher level of environmental sensitivity and energy efficiency to the building than others. The findings of this analysis will be presented with particular focus given to the daylighting analysis as it was found to have the highest impact on the facility's overall form. Details of the daylight harvesting design process will be presented with an in-depth analysis of how these processes will optimize the center's use of natural daylight and reduce the requirements of artificial lighting.

In addition to the daylighting findings, results related to low-flow fume hoods, storm water management, Carbon Dioxide monitors, geothermal heating and cooling, photovoltaic power generation and high-efficiency plumbing will be presented.

Labs21 Connection:

• Minimize environmental impact: In order to reduce the project's environmental impact, the LEED™ Rating System was adopted as a design guideline for the analysis and selection of sustainable design strategies.
• Optimize whole building efficiency on a life-cycle cost basis: Whole building efficiency was optimized through the use of parametric thermal analysis of the building's performance, extensive daylighting and solar angle studies. The National Park Service's Value Analysis and Design Advisory Board review processes were employed as tools for evaluating design options on a life-cycle basis.
• Range of energy and water efficiency strategies: A range of energy and water efficiency strategies will be employed including ground-source heat pumps, ultra-low flow plumbing fixtures and waterless urinals, extensive daylight harvesting, high-efficiency lighting, a low-flow fume hood, and natural ventilation.
• Evaluate on-site power generation: A roof-mounted photovoltaic array is being designed with technical assistance from Sandia Labs provided through FEMP grant.
• Build with green construction materials: For building materials selection, emphasis was placed on FSC certified wood products, materials with high recycled content, and local/regional materials.
