A GIS-based green supply chain model for assessing the effects of carbon price uncertainty on plastic recycling
Ren, Hongtao; Zhou, Wenji; Guo, Ying; Huang, Lizhen; Liu, Yongping; Ya, Yadong; Hong, Liyun; Ma, Tieju (Journal article; Peer reviewed, 2019)Recycling plastic can abate the environmental pollution as well as CO2 emissions by saving the carbon-intensive feedstock input. The uncertain carbon price places significant effects on the establishment and operation of ... -
Automated infection risks assessments (AIRa) for decision-making using a blockchain-based alert system: A case study in a representative building
Wan, Paul Kengfai; Huang, Lizhen; Lai, Zhichen; Liu, Xiufeng; Nowostawski, Mariusz; Holtskog, Halvor; Liu, Yongping (Peer reviewed; Journal article, 2022)Indoor air quality (IAQ) is an important parameter in protecting the occupants of an indoor environment. Previous studies have shown that an indoor environment with poor ventilation increases airborne virus transmission. ... -
Carbon emission of global construction sector
Huang, Lizhen; Krigsvoll, Guri; Johansen, Fred; Liu, Yongping; Zhang, Xiaoling (Journal article; Peer reviewed, 2017)The construction sector delivers the infrastructure and buildings to the society by consumption large amount of unrenewable energy. Consequently, this consumption causes the large emission of CO2. This paper explores and ... -
A Class-Imbalanced Heterogeneous Federated Learning Model for Detecting Icing on Wind Turbine Blades
Cheng, Xu; Shi, Fan; Liu, Yongping; Zhou, Jiehan; Liu, Xiufeng; Huang, Lizhen (Peer reviewed; Journal article, 2022)Wind farms are typically located at high latitudes, resulting in a high risk of blade icing. Data-driven approaches offer promising solutions for blade icing detection, but they rely on a considerable amount of data. Data ... -
Does urbanization lead to less energy use on road transport? Evidence from municipalities in Norway
Liu, Yongping; Huang, Lizhen; Kaloudis, Aris; Støre-Valen, Marit (Journal article, 2017)The relationship between urbanization, energy use, and CO2 emissions has been extensively studied in recent years, however little attention paid to the differences in urban forms. Previous studies implicitly assume that ... -
The environmental impact of rock support for road tunnels: The experience of Norway
Huang, Lizhen; Jacobsen, Pål Drevland; Bohne, Rolf André; Liu, Yongping; Bruland, Amund; Manquehual, Cristobal Javier (Peer reviewed; Journal article, 2020)Despite the high levels of investment in the construction of underground space, there has been relatively little research so far on the environmental impact of tunnelling and rock support. In an attempt to fill this gap, ... -
Glidestøp av heis- og trappesjakter i boligblokkproduksjon
Rudland, Hans Kristian Haadem (Bachelor thesis, 2022)Hensikten med denne bacheloroppgaven er å undersøke hvordan periodisk glidestøp av heis- og trappesjakter påvirker produksjonen på byggeplass. Studien tar utgangspunkt i glidestøpen på Ulven Vest, og er gjennomført i ... -
How do age structure and urban form influence household CO2 emissions in road transport? Evidence from municipalities in Norway in 2009, 2011 and 2013
Liu, Yongping; Huang, Lizhen; Onstein, Erling (Peer reviewed; Journal article, 2020)This article investigates the influence of age structure on CO2 emissions from household road transport by using an extended STIRPAT model plus data from 380 Norwegian municipalities for 2009, 2011 and 2013. After controlling ... -
