Performance of lightweight and heavyweight building walls with naturally ventilated passive and active facades

Dolaana Khovalyg, Mohammad Rahiminejad

Well-designed ventilated air-spaces behind external claddings in the building envelope can potentially reduce thermal energy flow in the entire wall structure. In this study, the impact of the dynamic thermo-hydraulic behavior of the flow in the naturally ...

Critical crystallization properties of an industrial-grade Zr-based metallic glass used in additive manufacturing

Roland Logé, Jamasp Jhabvala, Navid Sohrabi

The major challenge to overcome when processing metallic glasses (MGs) is to avoid crystallization. Therefore, time-temperature-transformation (TTT) diagrams are used, but they are often derived from experiments in which heating or cooling rates are limite ...

Hybrid Two-Phase Cooling Technology For Next-Generation Servers: Thermal Performance Analysis

John Richard Thome, Jackson Braz Marcinichen, Raffaele Luca Amalfi, Filippo Cataldo

This paper advances the work presented at ITHERM 2020 where a novel passive two-phase technology was introduced for more efficient cooling of datacenters compared to air-based cooling solutions (e.g. In-Room, In-Row, etc.). The proposed hybrid two-phase co ...

Planning Multi-Scale District Energy Systems with Hybrid Cooling Technologies and Decentralized Thermal Networks for Low Carbon Cities in the Tropics

Shanshan Hsieh

Energy demand for cooling of buildings is projected to drastically increase in the next decades. Urban areas in tropical Asia are expected to contribute a major share to this growing demand. These areas are characterized by a high urban density and a diver ...

Review on ventilation rates in the ventilated air-spaces behind common wall assemblies with external cladding

Dolaana Khovalyg, Mohammad Rahiminejad

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 enhance the ...

Impact of air-flow on thermal performance of air-spaces behind cladding (ASHRAE 1759-TRP)

Dolaana Khovalyg, Mohammad Rahiminejad

The project ASHRAE 1759-RP addresses the impact of the ventilated cavity behind external claddings on the thermal performance of the wall structure by defining “effective thermal resistance” of air gaps based on the linearized network of thermal resistance ...

Fungal Contaminants in Energy Efficient Dwellings: Impact of Ventilation Type and Level of Urbanization

Dusan Licina, Shen Yang

The presence of growing fungi in the indoor environment has been associated with the development of respiratory problems such as asthma or allergic rhinitis, as well as the worsening of respiratory pathologies. Their proliferation indoors could be a result ...

Hydration development and thermal performance of calcium sulphoaluminate cements containing microencapsulated phase change materials

Diana Londoño Zuluaga

Microencapsulated phase change materials (MPCM) incorporated in buildings walls can reduce indoor temperature fluctuations, conserving energy and enhancing thermal comfort. MPCM were incorporated in calcium sulphoaluminate cement (CSA) at high concentratio ...
