Assessment of the effect of mean and fluctuating wind-induced pressures on air infiltration and ventilation in buildings : a system theoretic approach
Energy and indoor air quality concerns have motivated extensive research on air infiltration and ventilation in buildings. Airflow models have been developed to study the problem and to assist in the building design process. Existing research concentrates on measurements, modelling and predictions …

From Field to Home: Assessing Air Infiltration and Soil Track-in Transport Pathways of Agricultural Pesticides into Farmworkers' Home and Identifying Risk Factors for Increased In-Home Pesticide Levels
… track-in on shoes, clothes and skin, and (2) air infiltration from nearby agriculture fields via agricultural pesticide drift in the vapor phase or adhered to resuspended soil particles. This dissertation estimates the relative contributions o the take-home/soil track-in and air infiltration …

The effects of building envelope parameters on energy performance for high-rise buildings in central Saudi Arabia
… weather in the country, building occupants use air conditioning extensively to overcome the heat and achieve thermal comfort. This research analyzed building envelope variables in an existing building in Riyadh, Saudi Arabia, and measured the effect on energy consumption and cooling loads based …

Simulation of a swine nursery to facilitate economical management
… by conduction, convection, radiation, and air infiltration. An existing sub-model was used to predict swine heat and moisture loss. The failure model was validated using a nursery constructed of concrete block. It performed well for cases with constant solar load, but tended to overpredict …

Using inverse regression models to create gray box models for industrial facilities
… transfer coefficient, surface area, and outdoor air mass flow rate of an industrial building through a simulation-based emulator. A simplified industrial building similar in size, energy usage, and physical parameters as a typical industrial facility was simulated in fifteen of the climate zones …

A Case Study and Analysis of Cleanroom Energy Use
… cleanroom chillers, and power use of all five air handling units are collected. It is revealed that cleanroom chiller and reheat power cost is approximately $103,000/yr, much higher than necessary, but also much less than the original estimate of $385,000/yr. During the data collection process, …

An Assessment of Indoor Infiltration Parameters for Black Carbon from Residential Wood Combustion and the Spectral Dependence of Light Absorption for Organic Carbon
… of 2009. The purpose was to investigate the infiltration parameters: air exchange rate, deposition rate, and penetration factor. The second part of this study investigated the light absorption properties of organic carbon from residential wood combustion, the dominant fraction of woodsmoke. …

Decision-making in the selection of retrofit facades for non-domestic buildings
… Despite their lack of insulation, high air infiltration, and solar gain, many such buildings from the 1960s-1970s are still in use today. Moreover, with UK buildings replaced at a rate of less than 2% a year, the majority of today's buildings will still be in use in 2050. Due to the …
