From the evaluation of the various building envelope alternatives, this study makes recommendations for the most appropriate systems to contribute to the Basis of Design of the McMurdo Station facilities. Ultimately, this Basis of Design of the building envelope will be conveyed during the Design-Build solicitation without limiting the respondents’ ability to meet the performance standards via comparable means. Building Envelope “The envelope has to respond both to natural forces and human values. The natural forces include rain, snow, wind and sun. Human concerns include safety, security, and task success. The envelope provides protection by enclosure and by balancing internal and external environmental forces. To achieve protection it allows for careful control of penetrations. A symbol of the envelope might be a large bubble that would keep the weather out and the interior climate in.” – Richard Rush, The Building Systems Integration Handbook MCMURDO STATION MODERNIZATION STUDY | APRIL 29, 2016 9 Methodology This McMurdo Building Envelope Study involves: DESIGN CRITERIA 1 This first step establishes the various design criteria for McMurdo Station's building envelope. Such criteria involves the physical parameters of climatic, energy use, aesthetic, constructibility, logistical considerations, the cultural parameters of aesthetics, and the value parameters of first and life- cycle costs. Specifically, these design criteria are established for the various portions of the facility’s building envelope: roof, wall, and floor. BENCHMARKING 2 Here, the report investigates solutions used for the building shell at a number of other recently constructed Antarctic Research Stations and Arctic facilities. COMPONENT RESEARCH 3 This step involves the identification of the full range of potential building envelope components. This range represents the full spectrum, from those that have been proven through general use in the building industry, to those at the forefront of innovation both within the building industry and allied industries. However, this study does not entertain technologies that are either unproven in the building industry, or are employed at an advanced level with the aerospace industry. COMPONENT EVALUATION 4 Upon identification of both performance criteria and component characteristics, this study evaluates these components for their ability to satisfy the performance criteria. This evaluation involves the relative ranking of performance, summarized in both graphic and written form. ASSEMBLY RECOMMENDATION 5 Finally, based on this evaluation, this study recommends the optimal combination of building components to form the building envelope system for the facilities at McMurdo Station.

Design Criteria are the factors and forces that impact the building shell and fenestration. GENERAL 1. All aspects of the construction, lifespan and removal of the building envelope shall be in conformance with the Antarctic Treaty. 2. Life Span of the McMurdo facilities shall be 50 years. This lifespan does not preclude replacement or refurbishment of specific envelope components. 3. On-site Labor to construct the enclosure shall be minimized. 4. Performance of the envelope shall be optimized to achieve an energy goal of 144 M BTU/yr. PHYSICAL PARAMETERS As the graphic diagram below indicates, the various physical parameters that form the basis for the physical design criteria involve: 1. Air Temperature gradients 2. Lateral and up-lift wind forces 3. Air infiltration 4. Ultra-violet intensity 5. Abrasion from air-born particulates 6. Structural & Thermal movement 7. Internal loading forces 8. Moisture Management CULTURAL PARAMETERS In addition to performing within the various physical parameters listed above, the building envelope shall respond to the following cultural parameters: 1. United States long-term Antarctic presence Durable, aesthetically timeless materials and forms 2. NSF presence and mission A display of the importance of the science mission through a design demonstrating thoughtful deliberation of the forms and the quality of the construction 3. Sensitivity to Place Facilities shall be designed to complement the unique Ross Island topographic, geological and climatic environment. 4. Promotion of Well-Being Indoor air quality, Thermal comfort, Views, Daylighting VALUE Both first cost and life-cycle cost are considered and evaluated. Life-cycle is not the life span of the building. Life span refers to the designed service life of the building, whereas life-cycle refers to the overall cost of the building through its life span as its is constructed, maintained, used, and removed. SYNERGIES The enclosure components being a part of a larger whole interact with other systems such as mechanical and structural designs. The ratios of opaque vs transparent enclosures are also a factor in the selection of the types of enclosures. The Design Phase will necessarily tune the enclosure components and assemblies to optimally satisfy the performance criteria in a cost effective manner.
