A rapid method for employing personal exposure monitors (PEMs) to measure carbon monoxide (CO) concentrations in high-rise buildings is described. The purpose is to determine whether or not a CO problem exists in a building, and, if so, what corrective actions should be taken. The methodology was applied to a 15-story building in Palo Alto, CA, where elevated CO concentrations were discovered on the first 11 floors . The source appeared to be an underground parking garage.
Approximately 35% of US single-family houses contain forced-air heating and cooling ducts that pass through unconditioned spaces. These duct systems have been shown to have a potentially large. Influence on energy use and ventilation rates. To investigate the parameters affecting the performance of these systems, a 31-house field study of distribution-system performance based on diagnostic measurements was performed in California, and an integrated airflow and thermal simulation tool was developed.
This paper summarizes negative psychological and physiological effects associated with underground buildings, identifies design strategies to alleviate them, and evaluates the effectiveness of some of these design techniques. The focus of the paper is on deep underground space with limited connection to the surface environment. A case study of design strategies used in deep underground office space is presented, and two proposed projects that further illustrate design techniques for deep milled space underground environments are described.
This paper presents the results of a research program that was conducted for ASHRAE by TRC- Environmental Consultants, Inc. The purpose of the study was to provide information on the effectiveness of existing ASHRAE ventilation guidelines for maintaining acceptable air pollutant levels and to develop a methodology for including economic utilization of energy in the consideration of future guidelines.
Many people are concerned about the emission potential of various furnishings, especially those of synthetic construction, placed in modern offices. Many IAQ professionals have blamed some of these furnishings for high levels of formaldehyde and volatile organic compounds. A researcher for Steelcase.
