Soleymani, A. (author), van den Brom, P.I. (author), Ahmed, Samir (author), Konings, Maaike (author), Sjoer, Ellen (author), Itard, L.C.M. (author), Zeiler, Wim (author), De Laat, Maarten (author), Specht, M.M. (author)The energy management systems industry in the built environment is currently an important topic. Buildings use about 40% of the total global energy worldwide. Therefore, the energy management system’s sector is one of the most influential sectors to realize changes and transformation of energy use. New data science technologies used in building...journal article 2023

Ghering, Victor (author), van den Brom, P.I. (author), Itard, L.C.M. (author), Schipper, H.R. (author)Low Temperature Heating (LTH) of buildings is a key feature when switching to renewable energy. Even when the capacity of LTH is high enough, LTH may adversely affect indoor thermal comfort in case buildings are not suitably insulated. This paper goes deeper into methodological issues when conducting a thermal comfort assessment. Thermal comfort...conference paper 2022

Wang, Z. (author), Meijer, A. (author), Itard, L.C.M. (author)In practice, automated energy performance fault diagnosis systems are seldom installed in HVAC systems. The main reason is that a specific Fault Detection and Diagnosis (FDD) setup is time-consuming and expensive because the existing methods are component-specific, not aligned with HVAC design practices, and not fully automated. 4S3F (four...conference paper 2022

van den Brom, P.I. (author), Smets, S.J. (author), Itard, L.C.M. (author)Many researchers have indicated the energy performance gap (difference between actual and predicted energy used in buildings), not only on an individual building level, but also on a building stock level. For policy makers it is important that predictions are correct on an building stock level to make them a useful tool to predict the effect of...conference paper 2022

Taal, Arie (author), Itard, L.C.M. (author)In practice, faults in building installations are seldom noticed because automated systems to diagnose such faults are not common use, despite many proposed methods: they are cumbersome to apply and not matching the way of thinking of HVAC engineers. Additionally, fault diagnosis and energy performance diagnosis are seldom combined, while energy...conference paper 2022

Guerra-Santina, Olivia (author), Rovers, T.J.H. (author), Itard, L.C.M. (author)Monitoring the energy performance of very low and zero energy buildings is fundamental to evaluate the efforts made to transition into an energy neutral built environment. Post occupancy monitoring has been embedded into current practice, supported by the availability of smart meters and affordable sensor technology. However, there is still a...conference paper 2022

Ortiz, Marco A. (author), Itard, L.C.M. (author), Bluyssen, P.M. (author)There are indications that energy-retrofitted buildings can create risks for indoor environmental quality (IEQ) and therefore for health and comfort of occupants. A review was conducted to identify and verify those risks, within three themes: building envelope, heating, ventilating and air conditioning (HVAC)-systems, and occupants. Publications...journal article 2020

Ioannou, A. (author), Itard, L.C.M. (author), Agarwal, Tushar (author)Indoor thermal comfort is generally assessed using the PMV or the adaptive model. This research presents the results obtained by in-situ real time measurements of thermal comfort and thermal comfort perception in 17 residential dwellings in the Netherlands. The study demonstrates the new possibilities offered by relatively cheap, sensor-rich...journal article 2018

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

Filippidou, F. (author), Nieboer, N.E.T. (author), Itard, L.C.M. (author)The existing housing stock plays a major role in the realization of the energy efficiency targets. The non-profit housing sector in the Netherlands dominates the housing market as it represents 31% of the total housing stock. In the municipality of Amsterdam, where this share is even 46%, subsidies were given to housing associations between 2011...conference paper 2016

Rasooli, A. (author), Itard, L.C.M. (author), Infante Ferreira, C.A. (author)Large deviations observed between the actual and theoretical gas consumption in Dutch dwellings, cast a shadow of doubt on the accuracy of the energy labeling method. In this sense, the accuracy of the calculation methods as well as the inputs being fed, fall under the question. According to several studies, the significance of wall’s thermal...conference paper 2016

Ioannou, A. (author), Itard, L.C.M. (author), Kornaat, Wim (author)Buildings in Europe are the largest end use sector and especially residential buildings account for two thirds of this energy use. Despite the fact that building characteristics play a major role in a dwelling’s energy consumption, occupant characteristics and behaviour significantly affect this energy use as well. The Ecommon campaign monitored...conference paper 2016

Taal, A. (author), Itard, L.C.M. (author), Zeiler, W. (author), Zhao, Y (author)A much occurring problem in the Energy Management Systems of existing buildings and HVAC services is that the measurements are unreliable. In this article a methodology is described which can be used to determine the presence of errors in energy monitoring, caused by faulty measurements. These errors can be detected and subsequently diagnosed....conference paper 2016

Majcen, D. (author), Itard, L.C.M. (author), Visscher, H.J. (author)In 2002 EU adopted the Energy Performance of Buildings directive which was subsequently adopted by the member states. However, more than a decade later, no national registers of certificates have become available publicly or to research institutions in order to give feedback on the introduced regulation. By exploring the 4 million certificates...conference paper 2014

Guerra-Santin, O. (author), Itard, L. (author)Governments have developed energy performance regulations in order to lower energy consumption in the housing stock. Most of these regulations are based on the thermal quality of the buildings. In the Netherlands, the energy efficiency for new buildings is expressed as the EPC (energy performance coefficient). Studies have indicated that energy...conference paper 2012
