An Analysis of the Performance of Different Intermittent Heating Controllers and an Evaluation of Comfort and Energy Consumption (HVAC&R RSCH JRNL OCT '97) (4091)
Gilles Fraisse, Joseph Virgone, Ph.D., and Jean Brau, Member, Centre de Thermique de Lyon (CETHIL), Villeurbanne, France
APC Liaison: James Vallort, NICOR, Inc.

This paper presents a new controller, based on fuzzy logic, to be used to control heating systems in intermittently occupied buildings. Comparisons with classical control methods demonstrate that the fuzzy controller gave superior results in terms of the control and optimization of the recovery time after setback. For each case, the differences in comfort and energy consumption between the different types of room were studied.

Yoshihiko Iawasaki, Tokyo Electric Power Corporation, Chiyoda-ku, Tokyo, Japan; Shuichirou Kobayashi, Akihiro Nagaiwa, and Yukihiro Yamada, Toshiba Corporation, Minato-ku, Tokyo, Japan
APC Liaison: James Vallort, NICOR, Inc.

This paper describes a district heating and cooling (DHC) plant operation support system and an on-line heat load prediction system. Shifting daytime electric power load to night by the use of thermal storage is especially advantageous for DHC plants using electricity. For effective plant operation, a schedule of DHC plant operation based on hourly heat load prediction of the next day should be made. The operation support system has two subsystems: first, the heat load prediction subsystem, which is necessary for heat pump operation, and second, the similar days selection subsystem from which similar days are selected from results of past plant operation.

Moderator: S. A. Sherif, Ph.D., Member, University of Florida, Gainesville, FL
APC Liaison: Robert M. Suggs, R.M. Suggs Company
The "ADP" calculation procedure for air-cooling processes located average coil-surface temperature on the saturation curve and relates moisture removal and heat transfer at the coil to the sensible and latent heat-gains of the room. Used in conjunction with the adiabatic air-mixing process, these two "straight-line" psychrometric principles define the occurrence of moisture precipitation (including in and around freezer doorways) and measures that fundamentally apply to its prevention or extraction. This forum addresses the question: "Why isn't ADP being used for freezer design?"

Field Studies of Thermal Comfort and Adaptation: Part 1
Sponsor: TC 02.01 Physiology and Human Environment
Chair: Gail S. Brager, Ph.D., Member, University of California, Berkeley, CA
APC Liaison: Filza Hassan, SHG Inc.
The adaptive approach to modeling thermal comfort acknowledges that thermal perception in "real buildings" can be influenced by a variety of contextual factors that are unaccounted for in laboratory studies or in the heat balance models and standards that are based on them. Field studies allow us to examine the thermal response of people who are naturally interacting with and adjusting to the thermal environment, thereby affecting their thermal expectations and preferences. Part 1 begins with a conceptual framework for understanding thermal adaptation. The following four papers each provide comparative results from field studies conducted in both air-conditioned and naturally ventilated buildings, including studies done in office buildings in the United Kingdom, a meta-analysis of data collected from field experiments in office buildings worldwide, and a field study of classrooms in the tropical climate of Hawaii.

Chair: Ron Kammerud, Ph.D., Member, Paradigm Consulting, Oakland, CA
APC Liaison: Debra Catanese, GPU Energy
With deregulation of the electric industry, real-time pricing (RTP) or other dynamic rates are expected to become more common. One of the barriers to achieving success with RTP has been that the building operators response to price typically must be implemented manually, which limits the number of systems that can be managed at a particular time, and the frequency with which operators can be expected to intervene in operation. This seminar describes approaches to automate response of building systems operation to time varying prices for electricity, and presents results from evaluations of the impact of these control technologies.

Advanced Turbulence Models for Room Airflow Prediction
Sponsor: TC 04.10 Indoor Environmental Modeling
Chair: Qingyan Chen, Ph.D., Member, Massachusetts Institute of Technology, Cambridge, MA
APC Liaison: James Buckley, P.E., 3D/International
In the past two decades the "standard" two-equation k-E model has been used intensively in room airflow prediction. Encouraging results have been achieved, but there are many problems unsolved. Due to rapid development in computer hardware, engineers are seeking advanced turbulence models, such as large-eddy-simulation, Reynolds-stress models, and variants of eddy-viscosity models, for better prediction of room airflows. This symposium discusses the results of room airflow prediction by those advanced models.

Field Studies of Thermal Comfort and Adaptation: Part II
Sponsor: TC 02.01 Physiology and Human EnvironmentPM
Chair: Gail S. Brager,Ph.D., Member, University of California, Berkeley, CA
APC Liaison: Filza Hassan, SHG Inc.
The adaptive approach to modeling thermal comfort acknowledges that thermal perception in "real buildings" can be influenced by a variety of contextual factors that are unaccounted for in laboratory studies or in the heat balance models and standards that are based on them. Field studies allow us to examine the thermal response of people who are naturally interacting with and adjusting to the thermal environment, thereby affecting their thermal expectations and preferences. Part 2 begins with a description of a global database of thermal comfort studies that is on the World Wide Web. The following three papers describe field studies conducted in an office building in San Francisco where workers have individual thermal control, centrally air-conditioned office buildings in Hong Kong, and both air-conditioned and naturally ventilated buildings in Bangkok.

Durability of Fenestration Systems
Sponsor: TC 04.05 Fenestration
Chair: Francois Dubrous, P.E., Natural Resources Canada, Ottawa, Ontario, Canada
APC Liaison: James Buckley, 3D/International
This symposium focuses on the energy aspect of durability of fenestration systems and discusses two key areas of concern: the long-term integrity of the glazing cavity of the insulating glass unit and the impact of air leakage on the continuing performance of the product. The first paper investigates the impact of muntin bars and suggests a refined test method for detecting potential problems. The second paper attempts to determine the extent of cold temperature air leakage from commercially available, operable windows, and the impact this has on a house's energy consumption. The third paper demonstrates how airflow through a window may actually increase its heat gains during the heating season, and evaluates the performance of a supply-air window to control airflow through two panes of glass.
