Abstract:

The purpose of this study was to perform an indoor air quality (IAQ) investigation at the Center for Applied Reproductive Science (CARS) to assess whether VOCs exist at levels dangerous to embryo. Formaldehyde, n-hexane, benzene, and styrene concentrations were measured at six locations. Formaldehyde concentrations were comparable to office and residential indoor air. N-hexane, benzene, and styrene were not detected. In addition, acetaldehyde, ethanol, and isopropyl alcohol were detected. IAQ parameters (carbon dioxide, temperature, humidity, pressure, and particulates) were measured at 22 sit

Abstract:

Poor air quality can greatly affect the public health. Research studies indicate that indoor air can be more polluted than the outdoor air. An indoor air quality monitoring system will help to create an awareness of the quality of air inside which will eventually help in improving it. The objective of this research is to develop a low cost wireless sensor system for indoor air quality monitoring. The major cost reduction of the system is achieved by using low priced sensors. Interface circuits had to be designed to make these sensors more accurate. The system is capable of measuring carbon dio

Abstract:

Acute indoor concentrations of benzene and ethanol were evaluated in the California Polytechnic State University San Luis Obispo’s pilot winery workroom. Air samples were collected during four different wine-making activities: fermentation, fermentation with Brix content testing, post-alcoholic fermentation pressing, and storage/finishing. Average workroom benzene concentrations ranged from 0.05 to 0.12 mg/m3. Ethanol concentrations in the winery workroom varied with the activity, ranging from 0.9 to 12 mg/m3. Pressing and fermentation with Brix content testing both led to higher indoor ethano

According to the International Panel on Climate Change, 30% of the energy used in buildings could be reduced with net economic benefits by 2030.

Abstract:

Air filtration is used to reduce particle concentrations in the indoor environment to provide improved occupant health due to reduced exposure. Increased focus on occupant health in emerging design standards is leading to the installation of higher efficiency filtration systems. These systems generally have higher resistance to flow and therefore impose a greater energy penalty. Previous air filter models have used simplified assumptions with regards to the dynamics of filter operation, which have limited the potential to determine energy efficiency or optimization approaches to system design

Abstract:

Bringing a building into existence that has never been made and used before is a kind of invention which is made by an architect. Being an architect necessitates the ability to synthesize separated things besides talent. The architect should relate different things such as people's needs and activities, natural features of earth, manufactured products, etc to each other in a systematic way that he or she can produce solutions for design problems and select the most suitable solution to meet people's needs. Thus a building can be imagined as if it physically exists, and as if it is occupied by

Existing work in outdoor air quality systems spans across community driven sensing, mobile sensing, and city or nationally supported sensing.

Deterioration of air quality is a growing concern in the world. Air pollution causes serious health problems and also can sometimes result in death. In order to assess air quality, long term and continuous monitoring of pollutant levels in ambient air are needed, such monitoring is often expensive, cumbersome, and resource intensive and so the monitoring programs often fail to succeed. This research focused on designing an ambient air monitoring system by integrating (1) low-cost sensor with a battery, (2) repurposed materials to fabricate all-weather housing for air monitors, and (3) electron

The photocatalytic properties of titanium dioxide have been widely studied since the discovery in 1972 of water photolysis by TiO2 electrodes. Rutile and anatase are the most studied of the different TiO2 polymorphs due to their chemo-physical properties. When irradiated with ultraviolet light, TiO2 is able to absorb photons, creating on the surface an electron and a positive “hole”. This electron-hole pair then reacts with water and oxygen, generating chemical radicals. These are very unstable and reactive species which can neutralise pollutants.
