“…Particularly, HRVS for residential buildings have recently emerged as an important research focus [14] that emphasises energy conservation in the building sector [15]. In this light, several studies on heating and cooling energy saving in residential buildings via the use of HRVSs have been conducted [16,17]. The extent of energy saving resulting from the use of HRVSs varies depending on the composition of the HRVS as well as the field conditions [18][19][20].…”

This study makes a novel attempt to analyse the effect of the bypass control and room control modes on ventilation energy saving in an 84 m 2 housing unit, which is the most frequently constructed unit-type among newly constructed apartment buildings in Korea. A heat recovery ventilation system was installed. The fan power consumption was measured via field experiments and analyses were made for potential energy savings. Experiments to confirm the power-saving effect owing to the application of the room control mode were performed under the heat recovery and bypass modes, using three air flow rates (0.5, 1.0 and 1.5 ACH). Additionally, the annual energy saving based on the application of the mixed mode (both bypass and room control modes) was calculated. The results obtained showed that when the mixed mode was employed, ventilation energy saving up to 10.76%-16.56%, which is greater than that obtained using only the heat recovery mode, was realized. Additionally, compared with all-room-ventilation, 26.69%-61.84% of ventilation energy could be saved if the mixed mode was applied only to the living room.

Systems that combine two or more of the above [32-35]. 98 According to the above-mentioned methods, separately applying CO2-based DCVS, occupancy-99 based DCVS or temperature-based DCVS only can result in fan energy saving in HRVS up to 15%-100 26% [28-31] and combining two or more of these abovementioned control techniques can result in 101 energy saving up to 60%. 102 Thus, a variety of studies on ventilation energy saving in residential buildings in diverse fields 103 have been reported. However, the drawback associated with these studies is that the analyses were 104 based on computer simulations [28-35]. Very few field experiments have been conducted to analyse 105 the fan energy savings of HRVS applied in Korean apartment building [27] and based on existing106 literature, no field experiments have been conducted to investigate fan energy saving via the 107 combination of a bypass control mode and a room control mode in the HRVS that are installed in 108 Korean apartment buildings. 109 The use of performance tests on HRVS in chambers to verify their actual field performance is 110 associated with several drawbacks. The HRVS installed in apartment buildings consist of several 111 components, including an outdoor air supply inlet and an exhaust outlet, a ventilation unit, a supply 112 duct and an exhaust duct, which all have an effect on internal and external static pressure. Thus, a 113 comprehensive analysis from the perspective of the entire ventilation system is needed. 114 Thus, the aim of this novel study was to analyse ventilation energy saving in apartment 115 buildings in Korea using data derived from on-site experiments performed to investigate the use of 116 the bypass and room control modes in HRVS.117 3.

The studies conducted in UK, Belgium and Netherlands [24][25][26][27][28] for different Passive House projects reported overheating periods during summer. The over focus on energy performance in nZEBs can lead to health and comfort problems.…”

a b s t r a c tIn times of great transition of the European construction sector to energy efficient and nearly zero energy buildings (nZEB), a market observation containing qualitative and quantitative indications should help to fill out some of the current gaps concerning the EU 2020 carbon targets. Next to the economic challenges, there are equally important factors that hinder renovating the existing residential building stock and adding newly constructed high performance buildings. Under these circumstances this paper summarises the findings of a cross-comparative study of the societal and technical barriers of nZEB implementation in 7 Southern European countries. The study analyses the present situation and provides an overview on future prospects for nZEB in Southern Europe. The result presents an overview of challenges and provides recommendations based on available empirical evidence to further lower those barriers in the European construction sector. The paper finds that the most Southern European countries are poorly prepared for nZEB implementation and especially to the challenge/opportunity of retrofitting existing buildings. Creating a common approach to further develop nZEB targets, concepts and definitions in synergy with the climatic, societal and technical state of progress in Southern Europe is essential. The paper provides recommendations for actions to shift the identified gaps into opportunities for future development of climate adaptive high performance buildings.

“…Their popularity has been shown to increase over recent years [11,12] due to their association with low energy buildings, e.g., Passivhaus [13]. However, the electric power needed to operate MVHR makes them part of "parasitic energy demand" systems [14].…”

Abstract:In temperate countries, heat recovery is often desirable through mechanical ventilation with heat recovery (MVHR). Drawbacks of MVHR include use of electric power and complex ducting, while alternative passive heat recovery systems in the form of roof or chimney-based solutions are limited to low rise buildings. This paper describes a biomimetic concept for natural ventilation with heat recovery (NVHR). The NVHR system mimics the process of water/mineral extraction from urine in the Loop of Henle (part of human kidney). ), respectively, for the month of January. With active heating and single occupant, the LoH Chamber consumes between 65.7% and 72.1% of the annual heating energy required by a similar naturally ventilated space without heat recovery. The LoH Chamber could operate as stand-alone indoor cabinet, benefitting refurbishment of buildings and evading constraints of complicated ducting, external aesthetic or building age.
