Faisal, Irum (author)One of the major risks to our planet today is climate change, which is a problem that worries people all over the world. There is a rise in global temperature levels and greenhouse gas emissions. The building industry has a huge share in this aspect. The current built environment accounts for almost 40% of energy consumption and 36% of CO2...master thesis 2022

Hopfe, Christina J. (author), Brembilla, E. (author), McElroy, Lori B. (author), McLeod, Robert S. (author), Gustin, Matej (author), Costola, Daniel (author)The global COVID-19 pandemic in 2020 has forced universities to completely re-think their teaching concepts to provide safe, remote teaching of students off-campus. One of the challenges of this rapid transition is ensuring that the quality of the learning experience remains high and that students are able to engage and thrive in this new and...conference paper 2022

Forouzandeh Shahraki, N. (author), Zomorodian, Zahra Sadat (author), Tahsildoost, Mohammad (author), Shaghaghian, Zohreh (author)Recent studies have focused on data-driven methods for building energy efficiency, by using simulated or empirical data, for energy-based design assessment rather than the common physics-based techniques, which are mostly time-consuming. In this paper, the feasibility of using seven different Machine Learning models, including three single...journal article 2022

Roelofsen, C.P.G. (author), Jansen, K.M.B. (author)In this study, using construction activities as an example, a proposal is made for the time-dependent prediction of the thermal sensation and the performance loss using a cooling vest, under transient conditions. The approach presented here can, mutatis mutandis, be used for any work activity and the use of a cooling vest, whether or not in a...journal article 2022

Roelofsen, C.P.G. (author), Jansen, K.M.B. (author), Vink, P. (author)This paper has the objective to initiate a discussion on potential improvements or extension of the validity of the original equation of the Predicted Percentage of Dissatisfied (PPD), according to (NEN-)EN-ISO 7730. This paper is to be regarded as a supplement to a paper on a re-derivation of the PMV equation in the Fanger model (Roelofsen,...journal article 2022

Roelofsen, C.P.G. (author), Jansen, K.M.B. (author), Vink, P. (author)There are different thermal perception models linked to a mathematical thermophysiological human model, with which the thermal sensation under stationary and/or dynamic conditions can be evaluated. Each of these perception and thermophysiological models have their own field of application. Stolwijk developed a thermophysiological human model...journal article 2021

Roelofsen, C.P.G. (author), Jansen, K.M.B. (author), Vink, P. (author)For sedentary activities, the PMV equation, derived by Fanger, is mainly based on the research of Nevins et al. (720 test subjects). Nevins' experiments were later on repeated by Fanger, but with 128 college-age Danish subjects and 128 elderly Danish subjects, instead of American subjects. Rohles did the research from Nevins et al. again, but...journal article 2021

Kale, Varun (author)The air-conditioning of commercial buildings accounts for approximately 50% of the total energy consumed in India’s commercial sector. Reducing this load is a key step towards minimizing India's greenhouse gas emissions. One culprit is the routine use of fully glazed façades which are chosen for aesthetics but are neither energy efficient nor...master thesis 2019

Roelofsen, C.P.G. (author)Stolwijk developed a thermophysiological human model which, to day, is still the basis and inspiration for many other thermophysiological human models. The Stolwijk model used in this study is improved with regard of the calculation of the skin temperature and equipped with clothing as well as thermal sensation. Fiala also developed a...journal article 2019

Mourtzouchou, Maria (author)The building sector is responsible for more than one third of resource consumption globally. Concerning the new construction, new regulations have been set, which impose that by 2020 all new buildings constructed within the EU should reach nearly zero-energy levels. The building envelope plays a strategic role in the energy and environmental...master thesis 2018

Alexiou, Maria (author)In order to limit the exorbitant energy consumption by the use of mechanical heating and cooling systems, several buildings are trying to adopt a heat storage<br/>system as a part of the energy system of the building. However, there are also passive systems that perform independently from the building’s energy system and store heat in...master thesis 2017

Ioannou, A. (author), Itard, L.C.M. (author)Reducing energy consumption in the residential sector is an imperative EU goal until 2020. An important boundary condition in buildings is that energy savings shouldn’t be achieved at the expense of thermal comfort. There is, however, little known about comfort perception in residential buildings and its relation to the PMV theory. In this...journal article 2017

(author)Thermal mass is usually positively associated with energy efficiency and thermal comfort in buildings. However, the slow response of heavyweight constructions is not beneficial at all times, as these dynamic effects may actually also increase heating and cooling energy demand during intermittent operation or can cause unwanted discomfort.
