Can building performance simulation reproduce measured summertime indoor conditions of a multi-residential building in good conformity? This question is answered by calibrating simulated to monitored room temperatures of several rooms of a multi-residential building for an entire summer in two process steps. First, we did a calibration for several days without the residents being present to validate the building physics of the 3D simulation model. Second, the simulations were calibrated for the entire summer period, including the residents’ impact on evolving room temperature and overheating. As a result, a high degree of conformity between simulation and measurement could be achieved for all monitored rooms. The credibility of our results was secured by a detailed sensitivity analysis under varying meteorological conditions, shading situations, and window ventilation or room use in the simulation model. For top floor dwellings, a high overheating intensity was evoked by a combination of insufficient use of night-time window ventilation and non-heat-adapted residential behavior in combination with high solar gains and low heat storage capacities. Finally, the overall findings were merged into a process guideline to describe how a step-by-step calibration of residential building simulation models can be done. This guideline is intended to be a starting point for future discussions about the validity of the simplified boundary conditions which are often used in present-day standard overheating assessment.

Abstract To date, the US Environmental Protection Agency has not published guidance for radon testing, diagnostics, or mitigation within large, non-residential buildings. Current research indicates that large buildings may contain construction features or mechanical systems that could inhibit the installation or operation of a mitigation system. Health and safety issues such as asbestos and fire codes may further interfere with the installation process. Studies also show that elevated radon can be restricted to a particular area or room within a building and not be uniformly distributed. A four-step, sequential protocol has been developed to address these issues and facilitate large building radon mitigation.

Abstract. Existing Dutch guidelines for the design of the drinking water and hot water system of non-residential buildings are based on outdated assumptions on peak water demand or on unfounded assumptions on hot water demand. They generally overestimate peak demand values required for the design of an efficient and reliable water system. Recently, a procedure was developed based on the end-use model SIMDEUM to derive design-demand-equations for peak demand values of both cold and hot water during various time steps for several types and sizes of non-residential buildings, viz. offices, hotels and nursing homes. In this paper, the design-demand-equations are validated with measurements of cold and hot water patterns on a per second base and with surveys. The good correlation between the simulated water demand patterns and the measured patterns indicates that the basis of the design-demand-equations, the SIMDEUM simulated standardised buildings, is solid. Surveys were held to investigate whether the construction of the standardised buildings based on the dominant variable corresponds with practice. Surveys show that it is difficult to find relationships to equip the standardised buildings with users and appliances. However, the validation proves that with a proper estimation of the number of users and appliances in only the dominant functional room of the standardised buildings, SIMDEUM renders a realistic cold and hot water diurnal demand pattern. Furthermore, the new design-demand-equations based on these standardised buildings give a better prediction of the measured peak values for cold water flow than the existing guidelines. Moreover, the new design-demand-equations can predict hot water use well. In this paper it is illustrated that the new design-demand-equations lead to reliable and improved designs of building installations and water heater capacity, resulting in more hygienic and economical installations.

The aim of this work is to develop approaches to automate the process of installing sensors for monitoring "smart home". The article briefly describes the emergence of the smart home system and the further spread of this system in Russia. “Smart Home” is a home control system that provides automatic and well-coordinated operation of a whole complex of systems, in particular, lighting control, which requires the use of correct placement of sensors. Such a system can provide benefits for people with disabilities. The sensor layout will optimize energy consumption. The paper gives a brief description of the classic sensor sets for a smart home. A classic set for a smart home are: control center, cameras, modules in the socket, wall switches, control modules and various sensors. The classification of sensors according to various characteristics and the method of connection is given. The article focuses on the placement of motion and light sensors, which are often the basis of a “smart home” and are used to control various devices. This paper describes the classic smart home circuit and lists its main components. An algorithm is proposed for determining the need for using standard models of motion and illumination sensors and their quantitative ratio from the room analysis, namely: the type of room (residential, non-residential), the size of the room, the presence of window and door openings. The presented algorithm contains the following steps: preliminary analysis of the room in which it is necessary to install motion and light sensors, take into account the characteristics of the sensors. Brief results of testing are given. This work shows that it is quite possible to arrange a “smart home” complex in an individual residential structure.

Mineral sepiolite as inorganic carrier, lauric acid(LA)-stearic acid(SA)as binary PCM(phase change material), CTAB as modifier, ethanol as solvent, mineral energy storage residential composite was prepared by intercalation, and the properties of composites were characterized using thermogravimetry(TG)/differential thermal analysis(DTA),scanning electron microscope(SEM),X-ray diffraction(XRD).Orthogo-nal experimental results show that the optimum proportion of composite materials is A3B2C1D3, the initial phase change temperature is 31.44 °C, phase transition peak temperature is 35.25°C, a wide range of endothermic peak is between 30.0~40.0°C, scope of phase change temperature is 3.81. LA-SA eutectic mixture could be retained by adding into 42.3 wt% porous sepiolite, treated at 80 °C. The weight loss of the composites is no more than 2% when melting/freezing cycling within 100°C, so it has good thermal reliability when applied to building material. Mainly due to relatively high content of mineral impurity, high temperature and CTAB can significantly help improve adsorption rate of mineral sepiolite. Sepiolite as a carrier material has features with low cost, broad sources, non-toxic and non-pollution. The composite material is a healthy residential energy-saving material, and it provides a good prospect for the realization of building energy efficiency, regulating room temperature in summer, and improving human comfort.

China’s rural houses are mostly courtyard-style independent houses. Such houses have certain characteristics, e.g., small mutual influences between houses, strong transformation flexibility, and an easier approach to using the natural environment to develop passive energy-saving characteristics. Therefore, rural houses have large energy-saving potential. In this study, for the first time, the cold alleys between buildings were used as an energy source for passive cooling and ventilation. Traditional houses in Shuhe, China, were used as a case study. The cold alleys in the settlements were used to compensate for the natural conditions in summer, and the cold air in the cold alley was introduced into each room using hot-press ventilation and by employing an accumulation effect from a corresponding patio. The room was ventilated and cooled, and air ducts were used to connect the rooms on both sides of the patio to improve the cooling efficiency. The research variables included the existence or non-existence of wall heat radiation (WHR), and the importance and influence of the WHR on the indoor conditions were verified. The cold air trapped in the new system formed an air partition wall, effectively blocking the direct influence of solar radiation on the room, reducing the heat transfer rate of the residential wall, and consuming part of the heat. In winter, based on using air ducts as supporting members, a glass roof was added to the patio, which improved the heat storage capacity of the patio and turned it into a constant-temperature heater for heating the building interior. Based on calculations, in the new system without WHR, the annual cooling load reduction was 55,417.33 kWh. With WHR, the annual cooling load reduction was 28,537.57 kWh. The annual cooling load of the air insulation wall of the new system was reduced to 1133.7 kWh. In winter, using the glass roof to increase the heat storage capacity of the patio reduced the heating load to 54,537.78 kWh.

Full textAbstract:
The experiment tested overconfidence in number skills among British graduates and non-graduates. The data were collected at a residential management training programme for part-time professional students. The aim of the research was to test whether graduate professionals, due to their higher qualifications, overstated their numeracy abilities compared to non-graduates. The experiment, conducted using E-prime, showed a significant interaction between the level of qualification and the overstatement of numerical abilities. The results support the hypotheses and showed that graduates rated themselves higher than their actual abilities: their test performance was not consistent with their confidence estimates. The findings are significant in relation to rethinking higher education curricula, which are currently under pressure to align with the needs of the economy. The authors advocate more inclusive and interpretive research for a greater understanding of the relevant issues to offer useful policy data and help higher education institutions prepare their graduates for task fulfilment and decision-making in a dynamic workplace. To date, few experiments have tested the numeracy level of graduates to corroborate the narrative communicated by employers. This study, despite the limited sample, is a first attempt and will serve as a reference for future, wider studies.

Full textAbstract:
Contrary to conventional air-conditioning systems in non-residential buildings, the air-flow conditions are almost never considered in ventilation systems for residential buildings. Both the air inlets and the outlets are usually located at unfavourable places. This situation culminates in large buildings with many flats, where simplest supply-air apertures are installed with respect to cost restrictions. With small air flow rates, the ventilation efficiency is very poor due to a lack of air mixture. In order to improve the situation, a new supply air aperture has been developed recently. The air flow rate is designed to vary with time, with a low auxiliary energy requirement, with clear maxima and otherwise reduced flow rate. Hence, the corresponding momentum was expected to improve the air mixture in the room. First measurements confirm that the transient flow conditions allow high intrusion depths and a good mixing of the air. The pulsating airflow reduces the risk of draughts and increases both ventilation efficiency and thermal comfort in the living area. Moreover, the energy efficiency is improved as the average air-flow rate can be reduced.

Full textAbstract:
Although single/multi-zone thermal models have their own advantages, like simple and fast computations of building energy demand, the accuracy of these models is problematic. The assumption of a uniform room temperature reduces the accuracy of the final energy demand results. In fact, the single/multi-zone thermal models are not able to predict indoor thermal behaviours or building energy demands accurately, if a non-uniform environment in a room or building is created by a single or multiple heating, ventilation, and air conditioning (HVAC) systems, i.e. an underfloor air distribution (UFAD) system. The research described in this article investigated the use of a new approach to improve the computational quality and accuracy of the heating energy demands of UFAD systems using an integrated zonal/multi-zone model. Several case studies were carried out, and the results demonstrate not only the advantages of UFAD systems used in a residential house in terms of energy saving, but also the importance of thermostat location in the prediction of building energy consumption. Additionally, the results indicate that the conventional single/multi-zone models are not appropriate to use for UFAD systems in the building energy demand predictions.

Full textAbstract:
The large energy demand from the HVAC industry for residential buildings, along with the ever growing need for the utilization of renewable sources of energy, has brought considerable attention to the area of induced ventilation. Windcatchers are green architectural structures historically used for the passive ventilation of the indoor spaces with the minimal non-renewable energy consumption. In this paper, a computational fluid dynamics (CFD) model is used to assess a windcatcher’s performance with different characteristics of the windcatcher design. For a single room with heat emitting objects, the effects of the windcatcher louver design and height were thoroughly evaluated in conjunction with a variety of dominant wind velocity and incident angles. A comparison was drawn between the ventilation efficiency for the cases of circular and rectangular windcatcher designs. Thermal discomfort (PD) values due to draft were calculated for different temperature and wind velocities. The developed model was employed to obtain the optimized configuration for the windcatcher-room system. The effect of ambient weather conditions on the results was investigated by performing the simulations for a range of air temperature and velocities. Results obtained in this paper provide windcatcher designers with valuable insights on the important design parameters such as windcatcher height, louver design and impact of ambient conditions.

The importance of the appearance of consumer products is widely understood. This paper considers an evaluation of the appearance of a technology-oriented product, the residential solar panel, from the perspective of individuals. This study uses a quantitative approach, visual conjoint analysis, to determine preferences for product appearance of solar panels, and further explores how presenting a solar panel in its context of use can influence the consistency of consumer preferences. Approximately 200 survey respondents were shown two kinds of images of solar panels, one of a standalone panel and the other of a panel installed on a roof. Results show a significant shift of preferences when first showing the non-contextualized image and then showing the contextualized image. Such preference inconsistency provides insights with which to inform the process of user-needs revealing.
