A novel methodology and new concept of structural dynamic moisture buffering for modeling building moisture dynamics
(Elsevier, 2020-05-19)
- article
This paper presents a new methodology that takes a physical-statistical approach to dynamically model indoor air humidity and moisture transport in building structures. A new concept, structural dynamics moisture buffer ...
Embodied, operation, and commuting emissions : A case study comparing the carbon hotspots of an educational building
(Elsevier, 2020-09-20)
- article
Building operational energy, mobility energy, and materials embodied energy contribute to a significant portion of the global greenhouse gas emissions. Buildings stand at the intersection of these three contributors and, ...
Development of a digital twin for real-time simulation of a combustion engine-based power plant with battery storage and grid coupling
(Elsevier, 2022-05-26)
