Glass Panels

This paper examines specific conceptual approach to the implementation of new "smart" materials having phase-changing own characteristics and maximum potential for their installation and exploitation of their performance in the commercial and residential buildings architecture. Such approach somewhat changes the usual traditional practice of installing "classical" materials, i.e. installable components into the architectural structure. The immeasurably superior performance of new elements installed in the architectural system is thus utilized, to the total energy benefit of the structural system. Using new "smart" components would result in energy cost-effective impact, reflected in the reduced the overall energy consumption of a given structure as well as in better effect sustainability of buildings in bioclimatic terms at the micro and macro levels in comparisonto the usual performance of traditionally constructed buildings.

The main purpose that should be put in the first place on residential constructions in the rural areas is how to guide the consumers to build residential buildings that are energy effective, comfortable, cost effective, and with construction techniques that are appropriate for the local conditions. Before investigating residential buildings that are suitable for local conditions, we have to discover the local economic status and their living habit in depth. This article puts emphasis on to survey the relationship between dwelling habits and energy consumption in the rural areas, also, space heating and cooling method, the use of solar energy, marsh gas and any other renewable sources of energy, as well as the thermal environment of residential buildings are investigated and analyzed. we conclude that, in the rim of Xi'an city, most of the fuel sources for space heating in winter used in the rural areas are fireweed and cornstock. Most of the energy sources are crops waste materials that are not environmental friendly, thus, it's necessary to popularize the use of solar energy and marsh gas.

The recent rapid transition in energy markets and technological advances in demand-side interventions has renewed attention on consumer behavior. A rich literature on potential factors affecting residential energy use or green technology adoption has highlighted the need to better understand the fundamental causes of consumer heterogeneity in buildings’ energy-related behavior. Unresolved questions such as which consumers are most likely to opt into demand-side management programs and what factors might explain the wide variation in behavioral responses to such programs make it difficult for policy-makers to develop cost-effective energy efficiency or demand response programs for residential buildings. This study extends the literature on involvement theory and energy-related behavior by proposing a holistic construct of household energy involvement (HEI) to represent consumers’ personal level of interest in energy services. Based on a survey of 5487 Korean households, it finds that HEI has a stronger association with consumer values, such as preferences for indoor thermal comfort and automation, than with socioeconomic or housing characteristics and demonstrates HEI’s potential as a reliable, integrated predictor of both energy consumption and energy-efficient purchases. The study illuminates the multifaceted influences that shape energy-related behavior in residential buildings and offers new tools to help utility regulators identify and profile viable market segments, improve the cost-effectiveness of their programs, and eventually promote urban sustainability.

This case study compared U.S. and Swiss homes with the goal of identifying construction practices that are most beneficial in terms of energy efficiency and life cycle costs. The research was a collaboration between the Departments of Mechanical Engineering Technology (MET) and Building Construction Management (BCM) at Purdue University and The Lucerne University of Applied Arts and Sciences (HTA Lucerne) in Switzerland. The first phase of this project compared U.S. and Swiss approaches to low energy residential buildings. Construction costs and annual energy consumption were estimated using homes with a similar size and layout, but with specific changes to one or more features that affect overall energy use. The results show that a Swiss-style low-energy home is not cost-effective for Indiana in the short term, but could become attractive after a relatively long (40+ year) period of home ownership. Recognizing that technology by itself will not minimize energy consumption, a second part of the project explored cultural norms that influence energy use. A survey of U.S. and Swiss college students was used to compare lifestyles and energy habits. It was found with a high level of confidence that Swiss students are more energy conscious than their U.S. counterparts.

Energy Consumption Pattern

According to the National Energy Balance report released by the Energy Commission of Malaysia in 2016, the residential sector uses 21.6% of the total energy in Malaysia. Residents waste energy through inefficient energy consumption and a lack of awareness. Building occupants are considered the main factor that influences energy consumption in buildings, and to change energy consumption on an overall scale, it is crucial to change individual behaviour. Therefore, this study focused on analysing the energy consumption pattern and the behaviour of consumers towards energy consumption in their homes in the residential area of Batu Pahat, Johor. A self-administrated questionnaire approach was employed in this study. The findings of this study showed that the excessive use of air conditioners was a significant factor in the increasing electricity bills of homeowners as well as the inefficient use of electrical appliances. Also, this study determined the effect of awareness on consumer behaviour. This study recommends ways to help minimise energy consumption in the residential area.

Limited research of heat integration has been conducted in the oleochemical field. This paper attempts to evaluate the performance of an existing heat exchanger network (HEN) of an oleochemical plant at 600 tonnes per day (TPD) in Malaysia, in which the emphases are placed on the annual saving and reduction in energy consumption. Using commercial HEN numerical software, ASPEN Energy Analyzer v10.0, it was found that the performance of the current HEN in place is excellent, saving over 80% in annual costs and reducing energy consumption by 1,882,711 gigajoule per year (GJ/year). Further analysis of the performance of the HEN was performed to identify the potential optimisation of untapped heating/cooling process streams. Two cases, which are the most cost-effective and energy efficient, were proposed with positive results. However, the second case performed better than the first case, at a lower payback time (0.83 year) and higher annual savings (0.20 million USD/year) with the addition of one heat exchanger at a capital cost of USD 134,620. The first case had a higher payback time (4.64 years), a lower annual saving (0.05 million USD/year) and three additional heaters at a capital cost of USD 193,480. This research has provided a new insight into the oleochemical industry in which retrofitting the HEN can further reduce energy consumption, which in return will reduce the overall production cost of oleochemical commodities. This is particularly crucial in making the product more competitive in its pricing in the global market.

Prediction Approach

With the development of modern power systems (smart grid), energy consumption prediction becomes an essential aspect of resource planning and operations. In the last few decades, industrial and commercial buildings have thoroughly been investigated for consumption patterns. However, due to the unavailability of data, the residential buildings could not get much attention. During the last few years, many solutions have been devised for predicting electric consumption; however, it remains a challenging task due to the dynamic nature of residential consumption patterns. Therefore, a more robust solution is required to improve the model performance and achieve a better prediction accuracy. This paper presents an ensemble approach based on learning to a statistical model to predict the short-term energy consumption of a multifamily residential building. Our proposed approach utilizes Long Short-Term Memory (LSTM) and Kalman Filter (KF) to build an ensemble prediction model to predict short term energy demands of multifamily residential buildings. The proposed approach uses real energy data acquired from the multifamily residential building, South Korea. Different statistical measures are used, such as mean absolute error (MAE), root mean square error (RMSE), mean absolute percentage error (MAPE), and R2 score, to evaluate the performance of the proposed approach and compare it with existing models. The experimental results reveal that the proposed approach predicts accurately and outperforms the existing models. Furthermore, a comparative analysis is performed to evaluate and compare the proposed model with conventional machine learning models. The experimental results show the effectiveness and significance of the proposed approach compared to existing energy prediction models. The proposed approach will support energy management to effectively plan and manage the energy supply and demands of multifamily residential buildings.

Since buildings are one of the major contributors to global warming, efforts should be intensified to make them more energy-efficient, particularly existing buildings. This research intends to analyze the energy savings from a suggested retrofitting program using energy simulation for typical existing residential buildings. For the assessment of the energy retrofitting program using computer simulation, the most commonly utilized residential building types were selected. The energy consumption of those selected residential buildings was assessed, and a baseline for evaluating energy retrofitting was established. Three levels of retrofitting programs were implemented. These levels were ordered by cost, with the first level being the least costly and the third level is the most expensive. The simulation models were created for two different types of buildings in three different climatic zones in Palestine. The findings suggest that water heating, space heating, space cooling, and electric lighting are the highest energy consumers in ordinary houses. Level one measures resulted in a 19–24 percent decrease in energy consumption due to reduced heating and cooling loads. The use of a combination of levels one and two resulted in a decrease of energy consumption for heating, cooling, and lighting by 50–57%. The use of the three levels resulted in a decrease of 71–80% in total energy usage for heating, cooling, lighting, water heating, and air conditioning.

Sustainable approaches for retrofitting buildings for energy efficiency are becoming necessary in a time when the building sector is the largest energy consumer. Retrofitting building stock is effective for reducing global energy consumption and decreasing resource exploitation. Less developed EU member states and neighboring developing countries show reluctance towards healthy and renewable materials. Implementation of sustainable materials for energy retrofitting is slowed down due to gaps in legislation and effective strategic programs, availability of bio-based materials, lack of knowledge regarding use and maintenance of renewable products, and marketing lobbies. Use of bio-based materials in refurbishment is important due to their negative or low global warming potential (GWP), low primary energy (PEI) need for production, cost-effective benefits, and recycling/reuse potential. Role of environmentally friendly solutions and low-carbon economy growth is particularly relevant in developing countries, such as Bosnia-Herzegovina, that cannot afford innovative energy recovery systems, yet possess a significant amount of poorly managed building stock. This research aims to analyze frameworks regarding retrofitting of residential buildings in Bosnia-Herzegovina and Slovenia. The analysis tackles indirect causes, studies the legal background, and examines strategic frameworks; thus, it indicates potential barriers for implementation of recommended retrofitting solutions based on renewable materials.
