The ventilation airflow rates in a demand-controlled ventilation strategy typically vary between a base (Vmin) and a maximum ventilation rate (Vmax). Classrooms have relatively short but intense hours of occupancy and a low Vmin can result in high energy savings. Our study aims to examine how...

This study aimed to assess whether building materials, furniture, and user equipment are sources of pollution that would influence the need for ventilation. Between 2017-2020, measurements were taken in four regular classrooms in a low emitting school and four modular classrooms in a...

COVID-19 pandemic has irreversibly changed the attitude towards office presence. While previously remote workers were met with skepticism and distrust, today the same applies to companies prohibiting remote working. Albeit many workspaces are half empty. In this paper, we offer insights into the...

Environmentally friendly functionalized inorganic–organic hybrid materials (polyhedral oligomeric silsesquioxanes—POSS) imparting anti-icing properties to a commercial waterborne polyurethane coating matrix have been successfully synthesized deploying a possible industrial manufacturing route by a...

A guarantee of safe and efficient power production by the means of green energy sources is an extremely important task, necessary to the popularize environmental-friendly solutions. Ice accumulation and water droplet erosion are some serious obstacles to increasing the power output of the wind...

Information Security Risk Management (ISRM) activities are essential for organizations seeking to control and monitor risk. However, it is well known that doing so is difficult, and the different ISRM activities provide different challenges. To provide support, ISRM tools can be used. Such tools can...

Current climate and energy policies aim for zero emission ports, emphasizing their key role in sustainable energy transition. However, the future demand and supply of energy is uncertain. The long-term interaction between transition policies, regulations, and techno-economic trends is difficult to...

Organized every 2 years, during years with no Indoor Air conference, Healthy Buildings conferences bridge the gap between science and profession, making it one of the most influential conferences on best-practice sustainable solutions for the indoor environment. Healthy Buildings Europe 2021 is...

This paper presents a flexible and scalable battery system for maritime transportation, integrating modular converters and hybrid battery technologies that are effectively implemented in real-world scenarios. The proposed system is realized with modular DC-DC converters, which do not require complex...

This paper presents the results of a research work accomplished to expand the initial dynamic model of Continental Europe (IDMCE) with the Nordic power system model (NPSM), where a pseudo steady-state HVDC representation for electromechanical transient stability studies on the AC system was used to...

This paper presents a simulation-based investigation of compatibility between grid forming converters with different control system implementations when operating in the islanded ac-grid of an HVDC-connected offshore wind farm. A system configuration with two HVDC-terminals connected to separate...
