Using Bio-signals with Smart Windows

This research was conducted to find out the relationship between humans’ bio-signals and electrochromic windows, which could be useful to create a possible mechanism of using bio-signals to control the windows. By using wearable sensors and remote sensors, subjects’ bio-signals like heart rate, skin temperature, and pupil sizes, and indoor environmental quality like temperature and … Continue reading Using Bio-signals with Smart Windows

Post Occupancy Evaluation in office: Study of environmental satisfaction and work productivity through hot desking system

Hot Desking workplace arrangements are becoming popular post COVID-19 where employees follow a hybrid work culture to reduce the spread of infection. Therefore, the objective of this research is to identify the factors that contribute to the environmental satisfaction and work productivity of the occupants while reviewing the IEQ performance of the selected office. This … Continue reading Post Occupancy Evaluation in office: Study of environmental satisfaction and work productivity through hot desking system

TINY HOUSE IN THE DESERT: A study in indoor comfort using moveable insulation and thermal storage

A tiny house for seasonal rangers was designed for the extreme climate and diurnal temperature fluctuations of Joshua Tree National Park. The challenging climate conditions resulted in an extensive investigation of the building envelope to act as a passive thermal storage system to naturally cool and heat the house. The north wall was designed as … Continue reading TINY HOUSE IN THE DESERT: A study in indoor comfort using moveable insulation and thermal storage

Data visualization in VR/AR: Static Data Analysis in Buildings

Virtual reality (VR) and augmented reality (AR) are two ways to make the direct perception of data through images of virtual data. People can collect data on temperature, humidity, and particle concentration at different locations in a building and then visually represent the data in three visual formats at different times by swiping to change … Continue reading Data visualization in VR/AR: Static Data Analysis in Buildings

Carbon Accounting Tool(CAT) in BIM: An Embodied Carbon Plug-in for Revit

Carbon Accounting Tool (CAT), a new software program, was created with .Net Framework using Visual Studio (VS). A class library was created in VS and associated with Revit API.dll to implement the interface between VS and Revit. The plug-in can read the element materials of the building model and calculate the total amount of embodied … Continue reading Carbon Accounting Tool(CAT) in BIM: An Embodied Carbon Plug-in for Revit

Indoor Air Quality for Human Health in Residential Buildings

This study investigates the effects of indoor air quality (IAQ) parameters (short term-changes in indoor CO2 and PM2.5 concentration) on four human bio signals. Pearson correlation, stepwise linear regression and random forest are applied in data analysis. The bio-signals (among four bio-signals) most associated with IAQ parameters, participants’ IAQ evaluation and thermal comfort are determined. … Continue reading Indoor Air Quality for Human Health in Residential Buildings

Dynamic Shading and Glazing Technologies: Improve Energy, Visual, and Thermal Performance

This research mainly provided methods to compare the performance of visual, energy, and thermal categories, and methods to put them into one scoring system to evaluate the comprehensive performance with the consideration of trade-offs. Performance of several shading and glazing options were evaluated. The results indicated that for either a small room with small window … Continue reading Dynamic Shading and Glazing Technologies: Improve Energy, Visual, and Thermal Performance
