Impact of Standard versus Tracked-based User Behavior into Energy Simulations of Open-Space Offices
Dolaana Khovalyg, Verena Marie Barthelmes, Arnab Chatterjee
This simulation-based study aimed to contribute to gaining knowledge on how much the deviation between occupant-related input by the national standard and by insitu measurements might impact predictions of heating/cooling needs in offices. Analysis was per ...
2023Experimental study of the hydrodynamic and thermal performances of ventilated wall structures
Dolaana Khovalyg, Mohammad Rahiminejad
The presence of a ventilated air gap behind the external cladding in a building envelope is known to have a tangible contribution to the overall performance of the wall assembly. In the present study, the hydrodynamic and thermal performances of ventilated ...
2023Influence of outdoor air pollution on European residential ventilative cooling potential
Dusan Licina, Evangelos Belias
Residential ventilative cooling via natural ventilation is influenced by outdoor air pollution. However, relative to climate, outdoor air pollution is not comprehensively considered in determining the ventilative cooling potential of buildings. To assess t ...
ELSEVIER SCIENCE SA2023Measuring the effective thermal resistance of ventilated air-spaces behind common wall assemblies: Theoretical uncertainty analysis and recommendations for the hot box method modifications (ASHRAE 1759-RP)
Dolaana Khovalyg, Mohammad Rahiminejad
A well-designed ventilated wall that incorporates air-space behind cladding can reduce energy use for conditioning buildings by adding a thermally resistive layer. The scarcity of thermal performance data and standardized test methods is a particular barri ...
2022Numerical and experimental study of the dynamic thermal resistance of ventilated air-spaces behind passive and active façades
Dolaana Khovalyg, Mohammad Rahiminejad
The variation of the thermo-hydrodynamic behavior of the airflow in the ventilated cavity behind external claddings in a wall structure could potentially affect the overall thermal resistance of the entire structure. Although the impact of an enclosed air- ...
2022Reaching 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 ...
Routledge 2022Heat recovery potential from ventilated passive and active facades
Dolaana Khovalyg, Mohammad Rahiminejad
A ventilated air-space behind external claddings can potentially affect the thermal performance of the entire building structure. In particular, in the Building Integrated Photovoltaic (BIPV) facades, ventilated cavities are typically present between the P ...
TU Delft OPEN2022Impact of the ventilated air-space behind traditional (passive) and BIPV (active) façades on the thermo-hydrodynamic performance of the building wall structures
For many decades, ventilated cavities in wall assemblies of buildings have been essential for creating moisture-resilient constructions by allowing airflow within the air gap to promote drying. In addition to that, the airflow in the cavity can contribute ...
EPFL2022Thermal resistance of ventilated air-spaces behind external claddings; definitions and challenges (ASHRAE 1759-RP)
Dolaana Khovalyg, Mohammad Rahiminejad
The presence of an air-space within a building envelope is known to have a varying contribution to the overall thermal performance of the wall assembly due to the combined effect of convection and radiation in the air cavity. In particular, the thermal res ...
2021Systematic Method for the Energy-Saving Potential Calculation of Air Conditioning Systems via Data Mining. Part II: A Detailed Case Study
Increased data monitoring enables the energy-efficient operation of air-conditioning systems via data-mining. The latter is projected to have lesser consumption but more comprehensive diagnosis than traditional methods. Following the companion paper that p ...
