New buildings have to satisfy stricter standards regarding energy efficiency and consumption. This results in higher insulation levels and lower air leakages that reduce heating demands.
Maria Justo-Alonso, Solveig Blandkjenn, Hans Martin Mathisen
RenovActive is a renovation project which took place in Brussels based on the concept of Climate Renovation that implies achieving an excellent indoor climate as well as a high energy performance.
Nicolas Galiotto, Peter Foldbjerg, Jens Christoffersen, Thorbjørn Færing Asmussen, Sabine Pauquay
Nearly all retail locations use mechanical cooling systems to ensure indoor comfort temperatures and mechanical ventilation to ensure adequate air exchange, primarily for hygienic reasons.
Annamaria Belleri, Matthias Haase, Sotirios Papantoniou, Roberto Lollini
The modelling framework IAPPEM was redeveloped to predict indoor radon concentrations in dwellings that have undergone an energy retrofit, and have experienced a consequent air tightness change.
James A. McGrath, Miriam A. Byrne
Increasing use of air-conditioning in India is applying upward pressure on energy demand and may have implications on dependability.
Devna Vyas, Michael Apte
There are three common methods used to analyse Indoor Air Quality in buildings: in-site measurements, laboratory measurements, or the simulation of indoor spaces using a validated computational model.
Constanza Molina, Benjamin Jones, Michael Kent, Ian P Hall
The harsh Norwegian climate requires buildings designed according to high standards. The airtightness of the building envelope is crucial to attain an energy efficient building and to avoid moisture problems.
Lars Gullbrekken, Petra Rüther, Tore Kvande
This paper aims to present the elaboration of a device able to modify the airtightness of a test House. This project has been conducted with three Master student groups in the framework of their research projects from 2015 to 2017.
Maxime Paquet, Marcelli Martin, Aline Bachelet, Ekaterina Obukhova, Emma Calamote, Florian Lae, Jérôme Nicolle, Marc Abadie
Indoor carbon dioxide (CO2) concentrations have been used in the fields of building ventilation and indoor air quality (IAQ) for decades.
Andrew Persily, Lilian de Jonge
It is estimated that HVAC systems represent the highest energy consumption (approximately half of the total energy consumed) and one of the highest cost, especially in non-residential buildings.
Elena Barbadilla-Martín, José Guadix Martín, José Manuel Salmerón Lissén, Pablo Aparicio-Ruiz
The use of open-source CFD has been growing in both industry and academia. Open-source CFD saves users a considerable license cost and provides users with full transparency of implementation and maximum freedom of customization.
Cong Wang, Sasan Sadrizadeh, Sture Holmberg
Mandatory building airtightness testing has come gradually into force in the UK, France, Ireland and Denmark.
Valérie Leprince, François Rémi Carrié, Maria Kapsalaki
The main focus of this research is to estimate the ability of a liquid desiccant (LD) system operation to remove microorganism particles.
Joon-Young Park, Eun-Ji Choi, Seong-Yong Cheon, Hye-Won Dong, Jae-Weon Jeong
This paper proposes a dedicated outdoor air system (DOAS) with thermoelectric module radiant cooling panels (TEM-RCP). The DOAS involves the concept of a decoupled system with a parallel sensible cooling unit.
Hansol Lim, Janghoon Shin, Shiying Li, Hye-Jin Cho, Jae-Weon Jeong
Recent studies examined a liquid desiccant indirect and direct evaporative cooling assisted 100% outdoor air system (LD-IDECOAS) as an energy conserving alternative to conventional air conditioning systems.
Hye-Jin Cho, Jang-Hoon Shin, Joon-Young Park, Won-Jun Kim, Jae-Weon Jeong
One of the problems presented by energy recovery ventilators (ERV) is the condensation/frosting problem that occurs during winter time. In order to prevent this problem, preheating outdoor air is the most common method used nowadays.
Won-Jun Kim, Shiying Li, Min-suk Jo, Eun-ji Choi, Jae-Weon Jeong
Natural ventilation (NV) is an efficient way of cooling buildings, and its energy saving potentials however depend on many parameters including local hourly weather and climate conditions, types of ventilations, indoor cooling loads (or heat gains
Jun Cheng, Dahai Qi, Ali Katal, Liangzhu (Leon) Wang
Existing protocols for the inspection of mechanical residential systems poorly address both the assessment of uncertainties and recommendations or specifications for measurement methods and devices to be used to guarantee low measurement uncertain
Adeline Bailly Mélois, Elodie Rousseuw, Isabelle Caré, François Rémi Carrié
This paper presents a ventilated solar collector with energy storage of fins containing Phase Change Material (PCM) in the air cavity and investigates its thermal performance.
Yue Hu, Per Kvols Heiselberg
This paper proposes a methodology to assess fan energy use savings when improving ductwork airtightness. This methodology is based on new standard FprEN 16798-5-1:2016.
