At the Core: Fundamental Building Science Education Matters More Than Building Type

As building technologies become more advanced, the need for highly skilled and qualified workers has increased. Both residential and commercial building industries struggle to capture the full benefit of these new technologies because of the limited building science knowledge base of the professionals researching, designing, building, and selling these structures. To help address this need, the U.S. Department of Energy’s (DOE’s) Residential Building Integration (RBI) program initiated the Guidelines for Building Science Education (GBSEs). These guidelines provide guidance on the fundamental building science knowledge base that is helpful for a wide range of building industry jobs. This effort provides a mechanism for training organizations to align core curriculum that can be applied to any building type. At the same time, DOE’s Commercial Building Integration (CBI) program has been spearheading a full suite of impactful initiatives including the Better Buildings Workforce Guidelines (BBWGs), which provide voluntary national guidelines from which select stakeholders can develop high-quality and nationally recognized training and certification programs. The BBWG framework helps to improve quality and scalability issues for five energy efficiency-related jobs: Building Energy Auditor, Building Commissioning Professional, Building Operations Professional, Building Operations Journey-Worker and Energy Manager. The residential and commercial building programs are both interested in helping to create better buildings through an improved workforce. The two program initiatives complement each other in many ways. The GBSEs pave the way for more specialized training and education offered by industry and academia, which lead to credentials that signify competency. The BBWGs cover credentialing for energy efficiency jobs—a critical area that DOE believed could benefit from incentives for credentialing bodies and building operators that would improve the energy efficiency of commercial buildings. This paper summarizes the steps DOE programs have taken to work together and the outcome of this symbiotic relationship.

Guidelines for Building Science Education

The U.S. Department of Energy’s (DOE) residential research and demonstration program, Building America, has triumphed through 20 years of innovation. Partnering with researchers, builders, remodelers, and manufacturers to develop innovative processes like advanced framing and ventilation standards, Building America has proven an energy efficient design can be more cost effective, healthy, and durable than a standard house. As Building America partners continue to achieve their stretch goals, they have found that the barrier to true market transformation for high performance homes is the limited knowledge-base of the professionals working in the building industry. With dozens of professionals taking part in the design and execution of building and selling homes, each person should have basic building science knowledge relevant to their role, and an understanding of how various home components interface with each other. Instead, our industry typically experiences a fragmented approach to home building and design. After obtaining important input from stakeholders at the Building Science Education Kick-Off Meeting, DOE created a building science education strategy addressing education issues preventing the widespread adoption of high performance homes. This strategy targets the next generation and provides valuable guidance for the current workforce. The initiative includes: • Race to Zero Student Design Competition: Engages universities and provides students who will be the next generation of architects, engineers, construction managers and entrepreneurs with the necessary skills and experience they need to begin careers in clean energy and generate creative solutions to real world problems. • Building Science to Sales Translator: Simplifies building science into compelling sales language and tools to sell high performance homes to their customers. • Building Science Education Guidance: Brings together industry and academia to solve problems related to building science education. This report summarizes the steps DOE has taken to develop guidance for building science education and outlines a path forward towards creating real change for an industry in need. The Guidelines for Building Science Education outlined in Appendix A of this report have been developed for external stakeholders to use to certify that their programs are incorporating the most important aspects of building science at the most appropriate proficiency level for their role. The guidelines are intended to be used primarily by training organizations, universities, and certification bodies. Each guideline can be printed or saved as a stand-alone document for ease-of-use by the respective stakeholder group. In 2015, DOE, with leadership from Pacific Northwest National Laboratory (PNNL), is launching a multi-year campaign to promote the adoption of the Guidelines for Building Science Education in a variety of training settings.

The Building Science Advisor: A Web-Based Tool to Assess the Durability of Building Envelope Components

The Department of Energy (DOE) and Oak Ridge National Laboratory (ORNL) have developed an innovative new design tool that will put building science expert advice in the hands of every building designer who cares to manage moisture risk in high-R envelope components. As modern buildings become increasingly more airtight, constructed with modern labor-saving materials, and equipped with air-conditioning, they have become less forgiving to moisture intrusion. The Building Science Advisor (BSA) provides building science knowledge and advice based on expert experience, field measurements, laboratory tests, and computer simulations.BSA users are prompted to enter relevant information about the building location, design, and material selection options like cladding, structural system, and insulation. Influential factors such as climate, building air tightness, material properties, and internal moisture loads are also considered to estimate and compare the moisture durability performance of several design options. If the BSA deems the assembly’s performance unsatisfactory, it will provide the reasons why, and suggest necessary changes to wall design to ensure more robust performance.Using the BSA tool enables building designers to confidently select assembly design characteristics that achieve their design goals with the least moisture durability risk. Links to design-specific guidance are also be provided to help users manage any remaining risk. This tool will further enable DOE’s Building Technologies Office (BTO) to meet its long-term energy goal of a 50% reduction in building energy consumption by reducing builder concern about using highly energy efficient wall systems.

Engaging a Diverse Workforce in the Building Sciences Through the JUMP Into STEM Program: Impact Study; Preprint

Ensuring inclusivity in building science professions requires engaging people from underrepresented demographics; unfortunately, many races, ethnicities, and genders continue to be underrepresented. The JUMP into STEM program works to rectify this, encouraging creative ideation and highlighting the unique perspectives of a diverse array of students. The top students are awarded internships that provide opportunities to work in building science research with close supervision from mentors in the field. In the research presented here, we investigate the impact of participation in JUMP into STEM on students' careers, including the impact on students from diverse backgrounds. Furthermore, we research students' awareness of career opportunities in building science, students' perception of their ability to meaningfully contribute to this field, and the career building opportunities that JUMP into STEM provides for students. Through participant interviews and data analysis, we measure program diversity, inclusion, and effectiveness at achieving goals. We find that among the hundreds of students who have participated in this program, more than 25 different majors and/or educational degree programs are represented and more than 45% of students attend minority serving institutions or historically black colleges and universities. The JUMP into STEM experience had a significant effect on career choices or career development for more than 80% of participants. Our results also indicate that the JUMP into STEM program is effective at promoting diversity in the building sciences and is successfully contributing to the larger effort within the building science industry to promote and ensure equity in technological progress and innovation.

Updating the Building Science Advisor (BSA): A Tool to Assist in the Design of Durable Building Envelopes

Predicting the moisture durability of building envelope components remains challenging due to multiple influencing factors, including material selection, assembly positioning, local climate conditions, air tightness, interior environment, and construction quality. Building codes increasingly emphasize energy efficiency through enhanced insulation and tighter envelopes but offer limited guidance on moisture durability considerations. Consequently, builders face uncertainty, particularly as new materials and assemblies enter the market.The Building Science Advisor (BSA) is a free, web-based expert system developed to address these challenges by providing actionable insights into the moisture durability and energy efficiency of both new and retrofit wall designs. Recently updated, we are now providing version 3.0 of the tool. BSA features significant user interface improvements, enhancing navigation and user interaction through a refreshed, intuitive design. Additionally, the tool incorporates a newly developed database containing pre-simulated wall assembly cases, significantly reducing response times and improving the accuracy of moisture durability assessments. Furthermore, the updated BSA includes moisture content as a performance criterion, providing users with a more comprehensive understanding of moisture-related durability risks. These enhancements enable rapid, reliable assessments tailored to specific climate zones and local building practices. BSA continues to offer targeted guidance on wall retrofit scenarios and delivers access to an expanded library of location-specific building science resources.This paper describes these key updates, highlighting the enhanced features, expanded capabilities, and overall improvements to user experience and educational content. The paper includes a demonstration that illustrates how the revised BSA effectively supports practitioners in designing durable, energy-efficient building envelope assemblies.

Hygrothermal Material Properties for Soils in Building Science

Saving energy in buildings is top of mind with today s building professionals. Although designing energy-efficient walls and roofs is mostly a no-brainer, ensuring that below-grade foundations do not generate moisture problems has become even more complex, particularly because of how soil is involved. Hygrothermal performance of soils coupled to buildings is complicated because of the dearth of information on soil properties. A computational approach for heat transfer through the ground has been well-defined, and simplified methods have been developed. These approaches, however, generally ignore the transfer of soil moisture, which is not negligible. The intention of an ongoing study at Oak Ridge (TN) National Laboratory, therefore, is to gather, comprehend and adapt soil properties from soil science as well. The obtained information must be applicable to related tasks in building science and validated with hygrothermal calculation tools, where additional plugins to the existing software code WUFI (an acronym for Warme unde Felichte Instructionar, which translates to unsteady heat and moisture) are required. (See the sidebar, opposite page, for specifics on WUFI.)Simulation results from WUFI are being compared with existing thermal-only measurements and are being accomplished with ongoing hygrothermal measurements. The final outcome of the study will be the evaluation of several soil types in several climate zones for a number of basement assembly types. The study will define the type of soil, together with the type of building construction considered most and least reliable with respect to energy consumption and moisture safety. Furthermore, the study will determine the influences that different soils have on total energy loss through the ground.

STEM Infrastructure Improvement: Wilson-Booker Science Building (WBSB)

The Division of Natural Sciences and Mathematics is housed in the Wilson-Booker Science Building (WBSB) which previously consisted of six classrooms, a lecture room, three biology laboratories, one physics laboratory, one chemistry laboratory, one research laboratory, and three computer laboratories. However, due to rapid expansion in STEM majors, there was a dire need for more classroom and laboratory space to accommodate this expansion. Further, since the College started integrating research into the curriculum in 2004 in order to keep pace with the national trend in science education, it has become apparent that one small research laboratory that accommodates 10 students will not keep pace with the growing needs of the new students interested in research. Therefore, it became imperative to add another research laboratory to augment the existing one. Thus, the new instrumentation/Research Laboratory will provide space for the new equipment and research space for an additional 8 - 10 students. In addition, the new WBSB wing also houses a Biochemisty/Molecular Biology Laboratory, an Organic Chemistry laboratory, an Animal Laboratory, a Seminar Room, two spacious classrooms, and 3 Faculty Offices. The impact of the new facility will be far-reaching.

Accessorizing Building Science – A Web Platform to Support Multiple Market Transformation Programs

As demand for improved energy efficiency in homes increases, builders need information on the latest findings in building science, rapidly ramping-up energy codes, and technical requirements for labeling programs. The Building America Solution Center is a Department of Energy (DOE) website containing hundreds of expert guides designed to help residential builders install efficiency measures in new and existing homes. Builders can package measures with other media for customized content. Website content provides technical support to market transformation programs such as ENERGY STAR and has been cloned and adapted to provide content for the Better Buildings Residential Program. The Solution Center uses the Drupal open source content management platform to combine a variety of media in an interactive manner to make information easily accessible. Developers designed a unique taxonomy to organize and manage content. That taxonomy was translated into web-based modules that allow users to rapidly traverse structured content with related topics, and media. We will present information on the current design of the Solution Center and the underlying technology used to manage the content. The paper will explore development of features, such as “Field Kits” that allow users to bundle and save content for quick access, along with the ability to export PDF versions of content. Finally, we will discuss development of an Android based mobile application, and a visualization tool for interacting with Building Science Publications that allows the user to dynamically search the entire Building America Library.

Hygrothermal Material Properties for Soils in Building Science

Hygrothermal performance of soils coupled to buildings is complicated because of the dearth of information on soil properties. However they are important when numerical simulation of coupled heat and moisture transport for below-grade building components are performed as their temperature and moisture content has an influence on the durability of the below-grade building component. Soils can be classified by soil texture. According to the Unified Soil Classification System (USCA), 12 different soils can be defined on the basis of three soil components: clay, sand, and silt. This study shows how existing material properties for typical American soils can be transferred and used for the calculation of the coupled heat and moisture transport of building components in contact with soil. Furthermore a thermal validation with field measurements under known boundary conditions is part of this study, too. Field measurements for soil temperature and moisture content for two specified soils are carried out right now under known boundary conditions. As these field measurements are not finished yet, the full hygrothermal validation is still missing

Building Science Advisor (BSA): A Tool to Assist in the Design and Education of Durable Envelopes

The moisture durability of a building envelope component can be difficult to predict. It depends on the materials used, the location in the assembly, the macro- and microclimate of the building, the air tightness of the interior environment and construction quality. Modern building codes require more insulation and tighter construction but provide little guidance about how to ensure these energy-efficient assemblies are designed and built to retain moisture durability. Furthermore, as new products are introduced to the market, builders are increasingly uncertain about the long-term durability of their building envelope designs. As building envelopes get tighter and better insulated, moisture management is key to a durable and high-performing wall assembly.
