Development of Thermal Envelope Design Guidelines for Federal Office Buildings by Andrew K. Persily Pdf
Office building envelopes are generally successful in meeting a range of structural, aesthetic and thermal requirements. However, poor thermal envelope performance will occur when there are discontinuities in the envelope insulation and air barrier systems, such as thermal bridges and air leakage sites. These discontinuities result from designs that do not adequately account for heat, air and moisture transmission, with many thermal defects being associated with inappropriate or inadequate detailing of the connections of envelope components. Despite the existence of these thermal envelope performance problems, information is available to design and construct envelopes that do perform well. In order to close the gap between available knowledge and current practice, the Public Buildings Service of the General Services Administration has entered into an interagency agreement with the Center for Building Technology of the National Institute of Standards and Technology to develop thermal envelope design guidelines for federal office buildings. The goal of this project is to transfer the knowledge on thermal envelope design and performance from the building research, design and construction communities into a form that will be used by building design professionals. This report describes the NIST/GSA envelope design guidelines development at the end of the first year of effort on the project. The effort to this point has consisted of a literature review of research results and technical information on thermal envelope performance and design, an assessment of existing design guidelines as they relate to the thermal envelope, and the development of a format and outline for the design guidelines.

PCM-Based Building Envelope Systems by Benjamin Duraković Pdf
PCM Enhanced Building Envelopes presents the latest research in the field of thermal energy storage technologies that can be applied to solar heating and cooling with the aim of shifting and reducing building energy demand. It discusses both practical and technical issues, as well as the advantages of using common phase change materials (PCMs) in buildings as a more efficient, novel solution for passive solar heating/cooling strategies. The book includes qualitative and quantitative descriptions of the science, technology and practices of PCM-based building envelopes, and reflects recent trends by placing emphasis on energy storage solutions within building walls, floors, ceilings, façades, windows, and shading devices. With the aim of assessing buildings’ energy performance, the book provides advanced modeling and simulation tools as a theoretical basis for the analysis of PCM-based building envelopes in terms of heat storage and transfer. This book will be of interest to all those dealing with building energy analysis such as researchers, academics, students and professionals in the fields of mechanical and civil engineering and architectural design

Building Physics of the Envelope by Ulrich Knaack,Eddie Koenders Pdf
The facade is the building’s interface with its environment. It is here that building physics parameters such as heat, humidity, sound and light interact with the building. All these influences need to be controlled by the building envelope in order to ensure the comfort of the user and the functional performance of the architecture. This introduction explains the most important phenomena and then relates them to design and building practice – which materials react in which way to these factors? How do facade systems deal with heat, humidity, sound and light? This practice-oriented book, which is the result of cooperation between an architect and a structural engineer, describes the most important facade materials and constructions under the aspect of their building physics performance.

Development of Experimental and Numerical Methods for the Evaluation and Optimization of Building Thermal Envelopes by Andrew Jordan Holstein Pdf
With recent emphasis on reducing building energy consumption, tools are needed that can determine the overall performance of building thermal envelopes in a manner that is accurate, efficient, and accessible. Two such methods--one experimental and one numerical--were developed for the evaluation and optimization of building thermal envelopes at the University of Wisconsin- Madison. A Rotatable Guarded Hot Box (RGHB) apparatus was designed and constructed for the large-scale thermal testing of post-frame building envelope designs. In addition to conducting standard thermal performance tests in accordance with ASTM C1363, the apparatus--capable of testing a wall or roof specimen up to 2.9 x 3.8 m--was designed to simulate the effects of air infiltration through the application of a static pressure differential across the test specimen. Utilizing a cable winch system and centralized pivot point, the entire apparatus may be rotated 360 degrees about its horizontal axis to test wall or roof specimens at any orientation. Using this apparatus, the thermal effect of various envelope design changes such as structural component placement and orientation, insulation type and geometry, and the inclusion and placement of air barriers may be studied. This apparatus employs an automated computer control system that acquires and stores temperature, pressure, air speed, and relative humidity data; varies heater and fan output; calculates and records key variables; and determines the completion of experimental objectives. Using this system, it is possible to expedite the conduction of accurate thermal experiments with a minimum of human interaction. The thermal performance of nine post-frame thermal envelopes was studied and optimized using a computational fluid dynamics model validated experimentally by the rotatable guarded hot box. In addition to providing thermal performance values for typical wall designs, this study proposed a new wall design that greatly increased thermal performance without sacrificing material efficiency. Study variables included structural geometry, level of insulation, and the presence and placement of radiant barriers. To reduce computational demand, modeling was primarily conducted using an area-weighted average of two-dimensional slices to represent three-dimensional assemblies. After modeling a portion of the assembly in three dimensions and comparing it with its two-dimensional counterpart, this simplification was found to result in less than a 6.7% error. Significant error (up to 57%); however, was determined to be integral to the simplifying assumptions commonly used by building designers, especially in envelopes common to the agricultural industry. This error was estimated to underpredict energy costs for a 2,200 m^2 cold-storage warehouse in Wisconsin by approximately $1,700 a year. The combination of these two distinct methods allows investigation of the effects that a wide array of factors have on the thermal performance of a building envelope. Through the investigation of these individual factors, thermal envelopes as a whole may be optimized for sustainability, based on a balance of the efficient use of energy, material, and labor.
