Prefabricated thermally-activated fiber-polymer composite building slab P-TACS: Toward the multifunctional and pre-fabricated structural elements in buildings

Thomas Keller, Dolaana Khovalyg

The traditional sequential design of building elements, where every element performs only one dedicated function, carries significant embodied energy. Thus, modular pre-fabricated load-bearing elements could overcome the disadvantages of the current carbon ...

Dynamic personalized human body energy expenditure: Prediction using time series forecasting LSTM models

Dolaana Khovalyg, Arnab Chatterjee

Dynamic human energy expenditure (EE) consists of energy costs for resting metabolism, food digestion, physical activity, and thermoregulation. Currently, multiple models predict EE mainly concerning physical activity, thus, discarding other factors contri ...

Modeling local thermal responses of individuals: Validation of advanced human thermo-physiology models

Dolaana Khovalyg, Mohamad Rida

Human thermo-physiology models (HTPM) are useful tools to assess dynamic and non-uniform human thermal states. However, they are developed based on the physiological data of an average person. In this paper, we present a detailed evaluation of two sophisti ...

DeepValve: Development and experimental testing of a Reinforcement Learning control framework for occupant-centric heating in offices

Dolaana Khovalyg, Amirreza Heidari

Space heating controls in offices usually follow static schedules detached from actual occupancy, which results in energy waste by unnecessarily heating vacant offices. The uniqueness of stochastic occupancy profile and thermal response time of each office ...

Non-intrusive physiological parameters sensing for personalized human thermal comfort prediction

Alexandre Massoud Alahi, Dolaana Khovalyg, Mohamed Ossama Ahmed Abdelfattah, Mohamad Rida

Sensing and projecting an individual’s human thermal comfort in buildings is a complex but crucial task for transitioning toward human-centered indoor climate control. Non-intrusive collection of physiological and personal information from the human body, ...

Human sitting behavior at office work and its effect on metabolic rate under varying thermal exposure

Dolaana Khovalyg, Ryan Liao

Assessing and optimizing human indoor comfort is challenging as physiological, psychological, and environmental variables influence it. Therefore, it is crucial to understand variability of human physiological parameters and underlying mechanisms. Metaboli ...

Interindividual variability of human thermoregulation: Toward personalized ergonomics of the indoor thermal environment

Dolaana Khovalyg

Objective The study was undertaken to show the magnitude of interindividual differences in energy expenditure (i.e., heat production) under normal living conditions with the aim of providing physiological evidence to support the advancement of a personaliz ...

Reaching Thermal Comfort Zone Limits for Resilient Building Operation: A Winter Case Study for Offices

Dolaana Khovalyg, Verena Marie Barthelmes, Arnab Chatterjee

A specific range of acceptable indoor thermal conditions is stipulated by building performance standards to assure minimum dissatisfaction of occupants. Thus, the operation of buildings in practice tends to follow a cautious approach by setting the indoor ...

Quality criteria for multi-domain studies in the indoor environment: Critical review towards research guidelines and recommendations

Dolaana Khovalyg, Verena Marie Barthelmes, Matteo Favero, Giorgia Chinazzo, Mandana Sarey Khanie

The perception, physiology, behavior, and performance of building occupants are influenced by multi-domain exposures: the simultaneous presence of multiple environmental stimuli, i.e., visual, thermal, acoustic, and air quality. Despite being extensive, th ...

Dynamics of metabolic rate in male individuals due to the meal and regular office activities

Dolaana Khovalyg, Jiyoung Kwak

Metabolic rate is one of the main parameters affecting the thermal balance of the human body and perception of thermal comfort. Typically, we consider a constant value for a specific type of activity (sitting quiet, standing, etc.) despite the time of the ...
