ABSTRACT Validation of the Load Collector Ratio (LCR) Method for Predicting the Thermal Performance from Five Passive Solar Test Rooms Using Measured Data by Daniel James Overbey Alfredo Femândez-Gonzâlez, Examination Committee Chair Associate Professor University of Nevada, Las Vegas The standard procedure used to analyze buildings that feature passive solar heating strategies is the load collector ratio (LCR) method. This procedure was developed by the Los Alamos National Laboratory between 1977 and 1984. As a result of the LCR method, one will obtain the solar savings fraction (SSF) of the input passive solar building. The SSF is the most widely accepted metric used to evaluate the effectiveness of passive solar heated buildings. The SSF may be defined as the extent to which a building’s passive solar feature(s) reduces a building’s auxiliary heat requirement relative to a comparable building devoid of passive solar feature(s). This thesis compares nearly two-years of monitored data collected fi'om five passive solar test rooms in Muncie, Indiana against the performance predicted by the LCR method as well as three other procedures related to passive solar heating analysis developed at the Los Alamos National Laboratory along with the LCR method. The conclusions of this thesis validate the LCR method with regard to projecting the SSF and auxiliary heat requirements for a range of passive solar heating strategies in a severe winter climate with predominantly cloudy sky conditions.

  • Feasible Upper Boundaries of Passive Solar Space Heating Fraction Potentials by Climate Zone Ted Kesik1 and William O'brien2 1Associate Professor, John H
    Feasible Upper Boundaries of Passive Solar Space Heating Fraction Potentials by Climate Zone Ted Kesik1 and William O'Brien2 1Associate Professor, John H. Daniels Faculty of Architecture, Landscape and Design, University of Toronto, Canada 2Assistant Professor, Department of Civil and Environmental Engineering, Carleton University, Ottawa, Canada Abstract Advances in energy modeling tools and techniques have caused passive solar design guidelines from a previous generation to be superceded by simulation. The ability to model building energy behaviour, heat transfer between multiple zones within a dwelling, and consider the effects of thermal mass and/or phase change materials, along with a variety of shading devices, has shed new light on passive solar energy utilization for space heating. In particular, the ability to accurately model the thermal and optical responses of high performance window technologies has uncovered new possibilities for solar apertures and feasible boundaries of passive solar space heating fraction potentials. This paper presents a methodology for assessing the feasible upper solar energy utilization boundary for the passive heating of houses, not as a replacement for simulation, but as a helpful guideline to designers, energy code authorities and utilities. For a particular climate zone and building geometry, the methodology can be employed to derive a range of building enclosure characteristics including: opaque component U-values; window and glazing U-values / solar heat gain coefficients, south-facing window-to-wall ratios, thermal mass levels, solar heat gain distribution rates and shading device placement and operating schedules. It can also inform decision makers involved in housing energy policy, the planning of subdivisions for new communities, and the design of housing typologies.

On the Fahrenheit scale, the freezing point of water is 32F and its boiling point is 212F at normal atmospheric pressure. Celsius temperature (°C) refers to temperatures measured on a scale devised in 1742 by Anders Celsius, a Swedish astronomer. The Celsius scale is graduated into 100 units between the freezing temperature of water (0°C) and its boiling point at normal atmospheric pressure (100°C) and is, consequently, commonly referred to as the Centigrade scale.

    INVESTIGATING THE LEVEL OF APPLICATION/EDUCATION OF PASSIVE/NATURAL SYSTEMS IN THE DESIGN OF SUSTAINABLE BUILDINGS IN THE US A Dissertation by MEHDI AZIZKHANI Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Jeff Haberl Committee Members, Liliana Beltran Zofia Rybkowski Wei Yan Head of Department, Robert Warden May 2019 Major Subject: Architecture Copyright 2019 Mehdi Azizkhani ii ABSTRACT The purpose of this research is to examine the degree of adoption and education of the concepts of natural systems for heating, cooling, and lighting (i.e., passive systems) versus artificial/mechanical systems (i.e., active systems) in the design of sustainable buildings by practitioners and educators. In addition, this research investigates the variables that may increase/reduce the application of these systems in architectural designs. Natural systems use renewable energies or ambient conditions, while mechanical systems often use non-renewable energies to heat, cool, ventilate, and illuminate buildings. Although an extensive list of publications about natural systems exist, there are very few studies about the approaches/tools used by professionals for the design of natural systems in sustainable buildings. This research seeks to fill this gap through three methodologies, including: a content analysis, a case study, and a survey questionnaire to practitioners/educators. The findings show that there is a low percentage of the application of passive/natural systems in architecture design in the US. To promote the application of passive systems, the clients’ desire/collaboration, building code/rating systems, and simulation tools for passive design are the most influential factors according to a survey of the practitioners in the US.

  • Impact of Weather Events (PDF)
    The Impact of Increasing Severe Weather Events on Shelter Prepared for: The Indoor Environments Division Office of Radiation and Indoor Air, U.S. Environmental Protection Agency Prepared by: Terry Brennan Camroden Associates 12/16/2010 Note: This report presents the findings, recommendations and views of its author, it does not necessarily reflect the opinion, approval or endorsement by the U.S. Environmental Protection Agency. 1 The Impact of Increasing Severe Weather Events on Shelter The 2009 report Global Climate Change Impacts in the United States (CCSP 2009) predicts that severe weather events will increase in frequency or severity. The authors forecast: • More days hotter than 90°F (Figure 1). • Increased drought and wildfire conditions. • More extremes in rainfall (Figure 2). • Increased frequency and intensity of hurricanes, tornadoes, ice and snow storms and consequent floods and loss of electric power (Figure 3). Figures 6, 7 and 8 clearly show that extreme weather events are already becoming more frequent. As this trend continues, people will need shelter from the increasingly severe weather. Extended periods of temperatures over 90°F, which result in increased deaths (Margolis 2008), are expected to increase across the U.S. Droughts will be more frequent in the western states. Wildfire frequency has increased dramatically in western states with hotter dry seasons and stronger winds. This development argues for fire‐protective houses and landscaping. Increases in very heavy rains, hurricanes and other extreme storms are likely to result in more frequent and extensive flooding and, when the rains do not lead to floods, to more moisture problems in buildings.
