Alternative Method For Low Frequency Impact Sound Measurement For Building Field Tests, Sunit Girdhar Jan 2023

Alternative Method For Low Frequency Impact Sound Measurement For Building Field Tests, Sunit Girdhar

Dissertations, Master's Theses and Master's Reports

What do high heels, dog nails, and dragging furniture have in common? They are all frequent sources of noise pollution and annoyance in multi-story buildings. Building codes exist to control and mitigate such noise, but these codes are outdated and fail to protect the residents against noise annoyance. Footstep noise is still the number one cause of complaints among the residents. The impact performance of floor-ceiling assemblies is characterized using a single-number rating called the Impact Sound Rating (ISR). A standard tapping machine is used in pre-defined locations on the floor and the radiated Sound Pressure Level (SPL) is measured …

Performance Modeling And Analysis Of A Thermoelectric Building Envelope For Space Heating, Xiaoli Liu, Ming Qu, Kazuaki Yazawa, Jorge Kohanoff, Piotr Chudzinski, Lorenzo Stella, Brian Norton, Niall Holmes Dr., Ruchita Jani, Hongxi Yin Jul 2022

Performance Modeling And Analysis Of A Thermoelectric Building Envelope For Space Heating, Xiaoli Liu, Ming Qu, Kazuaki Yazawa, Jorge Kohanoff, Piotr Chudzinski, Lorenzo Stella, Brian Norton, Niall Holmes Dr., Ruchita Jani, Hongxi Yin

Conference papers

To provide energy-efficient space heating and cooling, a thermoelectric building envelope (TBE) embeds thermoelectric devices in building walls. The thermoelectric device in the building envelope can provide active heating and cooling without requiring refrigerant use and energy transport among subsystems. Thus, the TBE system is energy and environmentally friendly. A few studies experimentally investigated the TBE under limited operating conditions, and only simplified models for the commercial thermoelectric module (TEM) were developed to quantify its performance. A holistic approach to optimum system performance is needed for the optimal system design and operation. The study developed a holistic TBE-building system model …

Dewaxing Bulding Containment, Liam Gahan, Katarina Nikolic, Emily Ziemba Apr 2022

Dewaxing Bulding Containment, Liam Gahan, Katarina Nikolic, Emily Ziemba

Student Scholarship – Engineering

This project will be on the Nutrition and Health side of Kensing where we manufacture Vitamin E. The problem for the students to solve will be the lack of secondary containment for our dewaxing building. The building uses acetone to thin the vitamin E for filtering to remove pesticides. We used to have onsite waste treatment, so the acetone could go right to our process sewer, but the onsite waste treatment has since been removed. If acetone goes to the process sewer today (i.e. if a spill were to occur), we would be fined by the city. If we plug …

The Impact Of Covid-19 On Building Energy Consumption In New York City, Martha A. Olaleye Jan 2022

The Impact Of Covid-19 On Building Energy Consumption In New York City, Martha A. Olaleye

Dissertations and Theses

Since February 2020, the spread of COVID-19 affected the world economy, with the population of people contacting the virus in New York City at that time being at the highest in the United States of America. Thus, the need for remote/online learning was adopted for the safety of faculty, staffs, and students of New York Educational institution like CCNY. In the study, I focused on energy consumption as regards to COVID and POST-COVID periods in New York City (NYC), since most employees are working from home and schools are online which implies that most commercial buildings are vacant. Also due …

Fate And Transport Of The Microbiome In Built Environments, Dahae Seong Oct 2021

Fate And Transport Of The Microbiome In Built Environments, Dahae Seong

Theses and Dissertations

Buildings are complex ecosystems evolving continuously. Indoor components such as occupants, ventilation system, and building structures influence the microbiome. To shed light on how the microbial population in a building will respond to such a fluid system, the fundamental interactions between microbes and the indoor ecosystem must be understood. Buildings are being designed as air-tight structures to save energy; however, this could lead to degradation of indoor air quality through indoor sources of contaminants and/or containment of pollutants in the room or introduce outdoor pollutants indoors depending on the ventilation conditions. In addition, transmission of infectious microbes in indoors threaten …

Research On Building Mechanism Model Simulation In Energy-Saving Control, Bai Yang, Decheng Yuan, Li Ling Mar 2020

Research On Building Mechanism Model Simulation In Energy-Saving Control, Bai Yang, Decheng Yuan, Li Ling

Journal of System Simulation

Abstract: In the existing building system, the energy consumption is huge, the control system is complex, and the electricity cost is high. In order to reduce the cost of electricity, the mechanism model of the building is established for simulation. The accuracy of the model is verified by simulation to confirm the model applicability to the building system. Comparing the constant electricity price with the time-varying electricity price, the system under the model predictive control can response to the price change of electricity with time and can achieve the cost control and energy-saving.
