Multi-objective optimization of energy-efficient retrofitting strategies for single-family residential homes: Minimizing energy consumption, CO2 emissions and retrofit costs

The retrofitting of buildings for improved energy efficiency has been recognized as crucial for achieving climate mitigation goals in Bosnia and Herzegovina (B&H). However, performing multi-objective optimizations for retrofitting existing buildings poses challenges, as it requires balancing conflicting objectives such as retrofit costs, energy savings, and CO2 reduction. To tackle this challenge, we employed a multi-objective analysis approach that aims to identify Pareto-optimal solutions for retrofitting, striking a balance between energy consumption, CO2 emissions, and retrofit costs. In this study, we utilized a combination of Full Factorial Design (FFD) and the state-of-the-art NSGA-III framework to evaluate energy-efficient (EE) retrofit strategies for residential buildings in B&H. The analysis was based on the existing building database from the national TABULA study, serving as a fundamental reference. By analyzing this data, we aimed to determine the optimal approach for EE retrofitting in single-family homes (SFH). Key results indicate that upgrading external walls and improving heating system efficiency are the most effective measures for reducing energy consumption and CO2 emissions. However, these measures come with higher retrofit costs. A multi-objective optimization approach identifies a set of non-dominated solutions representing energy efficiency retrofit measures with the lowest specific final energy for heating, specific CO2 emissions, and overall retrofit costs. The top-ranked set of measures achieves a Simple Payback Period (SPP) of 19.9 years. The insights gained from this study are intended to provide valuable guidance to decision-makers in formulating cost-effective and energy-efficient retrofitting strategies that simultaneously minimize annual energy consumption, CO2 emissions, and retrofit costs.

Evaluation of frost prevention strategies for membrane energy exchangers

In cold climates, the application of heat recovery is restricted by the issue of frost, which causes potential damage to heat exchangers and degrades their effectiveness. Membrane energy exchangers (MEEs), which enable simultaneous heat and moisture transfer, can reduce and delay frost formation and accumulation in cold climates. MEEs are recognized as the essential component for the new generation of Heating, Ventilation, and Air Conditioning (HVAC) systems. Despite of extensive studies on heat and mass transfer characterising and increased use of MEEs, the evaluation of suitable frost control strategies for the emerging MEEs in cold climates are still missing. This study presents numerical models of a quasi-counter-flow membrane energy exchanger (QCFMEE) and a quasi-counter-flow heat exchanger (QCFHE). Three different frost prevention strategies are examined: preheating outdoor air, heating room air and bypassing outdoor air. These strategies’ threshold values to prevent frost are calculated numerically and validated against experimental measurements. The results show that QCFMEE has lower threshold values and thus better frost tolerance ability compared with QCFHE because of mass transfer through the membranes. Moreover, the frost prevention strategies are evaluated based on annual energy consumption, energy saving ratio (ESR), and complexity of control for real-life applications. The simulated results show that among the discussed frost prevention strategies, preheating outdoor air has the advantage of the lowest energy consumption and highest ESR. Meanwhile, heating room air consumes the most energy and faces the problem of overheating outdoor air. Finally, concerning the bypassing outdoor air strategy, the significant fluctuation of its threshold values increases the complexity of control for real-life applications.

Assessment of the Role of Photovoltaic Systems in Reducing the Carbon Footprint of Wastewater Treatment Plants

<p>Wastewater treatment plants (WWTPs) consume large amounts of energy and thus cause an increase in carbon footprint. For this reason, it has become important not only to meet the discharge criteria in treatment plants, but also to reduce the carbon footprint resulting from treatment processes and energy use. In this study, the effect of supplying the energy required by a real domestic biological wastewater treatment plant from a photovoltaic (PV) system on the reduction of its carbon footprint was investigated. For this purpose, the annual energy consumption profile of the plant was prepared, and direct emissions from treatment processes and indirect emissions from electricity consumption were calculated for 2020 and 2021. Indirect emissions contribute 54% and 69% to the total carbon footprint of the plant for 2020 and 2021, respectively, while direct emissions contribute 46% and 31%. With the partial transition of the plant to a PV system in 2021, annual electricity consumption decreased by 401,000 kWh/year and the carbon footprint decreased by 21% to 819 tCO2e. In this way, the plant also achieved 40% economic savings. If the plant meets all the energy it needs from the PV system, it will reduce its carbon footprint by 45%.</p>

Improving the Energy Performance of a Household Using Solar Energy: A Case Study

In the global context of energy transition from fossil fuels to renewable sources of energy, solar energy plays a key role in electricity generation, having the highest annual growth in the last years. This case study focuses on improving the overall energy efficiency of a household through thermal retrofitting, harnessing solar energy with photovoltaic (PV) systems and using air-source (ASHP) or ground-source (GSHP) heat pumps. The electricity generated by the PV systems is used to power the heat pumps and all other electricals of the household. The simulations for the ASHP and GSHP systems were conducted with GeoT*SOL software, while for electricity generation by PV systems, PV*SOL Premium software was used. The comparative results show: a decrease in the heating load to about 51.56%; an annual heating requirement of 53.88% of the normed one; an energy consumption index of about 58.34 kWh/m2·year; an annual energy consumption reduction of 88% for ASHP and 91% for GSHP, compared with the current gas heating system; 34% of the household consumption was covered by the PV system in the case of using ASHP and 36% for GSHP; and lower operating costs by 47% for the PV system with ASHP and 53% for the PV system with GSHP.

Experimental study on performance improvement of a household refrigerator with a flying-wing evaporator

In order to improve the performance of a household refrigerator, a flying-wing evaporator (FWE) is to replace the original finned tube evaporator (FTE). Different from the FTE, the fins of the FWE are formed directly on the tube by shoveling movement. Therefore, the FWE has high efficient heat transfer performance due to no thermal contact resistance between the tubes and the fins. According to different combinations of fin pitch and number of tube rows, three different structures of FWE are designed and tested in comparison with the original FTE on a double-door household refrigerator. The results show that the FWE shortens the cooling duration by 0.32 h (9.3%) and reduces the annual energy consumption by 4.28% with a 25% reduction in volume and a 13.5% reduction in refrigerant charge. This study proves that applying a FWE into a household refrigerator instead of the traditional FTE is one of the effective ways to decrease the volume of evaporator, reduce the energy consumption of refrigerator and enhance the effect of food preservation.

Lavanta İçin Yeni Bir Teknolojik Uygulama Alanı ve Tarımsal Üreticiler İçin Ekonomik Kar Analizi

Nowadays, the energy and agriculture sectors are united for financial efficiency, and it brought the question to minds “can be stored the electrical energy that used in agriculture with an agricultural product?”. In this study, lavender essential oil, it obtained from Lavandula angustifolia, was used as a part of energy storage system. The essential oil was produced by distillation method. To energy storage performance analysis, the simple electrochemical capacitor was formed with platin foils and lavender essential oil. The capacitor application performances showed that the lavender essential oil can energy storage up to 4 Voltages (V). A capacity of 92 milli-Farad per cm2 (mF/cm2) was obtained with Lavender essential oil in the range of 0-4 V, and this value showed that lavender essential oil can be used in capacitors, as an electrolyte material. The results when evaluated in terms of agricultural economics, 1 million capacitors with a size of 1 cm2 can be produced with 1 ton lavender crops production per decare. Moreover, with lavender capacitors, the amount of energy required for a farm of 1000 hectares can be stored with 1000 capacitors of 10 cm2. Also, the stored energy is more than the farm's annual energy consumption, saving the farm ~534 USD annually on energy costs. In the case that all farm energy is produced with renewable energy sources, the annual profit is calculated as ~23697 USD. Also, the exploring of electrochemical capacitor electrolyte property of lavender essential oil could create an alternative sales pitch for agricultural producers.

Phenomenon of courtyards being roofed and its significance for building energy efficiency

Courtyard building is an important type of vernacular architecture, widely distributed in different climate zones around the world. Traditionally, courtyards are characterized by opening to the sky, providing buffer spaces for ventilation and light for the surrounding buildings. However, in Hebei, China, local buildings are showing an evolution trend characterized by the courtyards being roofed (CBR). This spontaneous evolution presents the diversity of CBR technologies (CBRTs), including light-transmitting CBRTs (T-CBRTs) and non-light-transmitting CBRTs (NT-CBRTs). Based on field measurements and simulation technology, the improvement effect of CBR on building energy efficiency (EE) is analyzed, and the EE of different CBRTs is compared. The results show that, T-CBRT and NT-CBRT can reduce the annual total energy consumption of open courtyards by 19.97% and 15.41% respectively without upgrading the original envelope structure. The analysis of the impact mechanism shows that CBRT increases the temperature of the courtyard and the room by improving the solar energy collection efficiency and expanding the heat storage space, which effectively reduces the heat leakage caused by the envelope and ventilation, and shortens the heating time. The light transmittance of the roof material is the most critical parameter affecting the EE of T-CBRT, and the roof height largely determines the performance of NT-CBRT. Multi-layer glass or concrete panels are not the best choice for CBRT roofing materials, and plastic films or polycarbonate sheets with high light transmittance and anti-aging are recommended. CBR is considered as a promising development direction because it can reduce the economic burden of energy consumption for local farmers by improving the EE of buildings.

(Invited) Electrocatalytic Synthesis of Ammonia and Urea

Many industrial chemical processes involve a high-energy demand (often still derived from fossil fuels), toxic reactants, and the production of high amounts of waste. A good example is the production of ammonia and urea via the Haber-Bosh and Bosch-Meiser processes, respectively. These two nitrogen-containing compounds are mostly used in the fertilizer industry and with the increase in the world population, their production is expected to increase. Additionally, NH3 itself is responsible for 2% of the annual world energy consumption and has a carbon footprint of 1.5 tons of CO2 per ton of NH3 [1]. Therefore, the development of more efficient, less hazardous technologies that are based on renewable energies to produce valuable N- containing compounds, has become one of the most challenging topics for chemical synthesis. By using electrochemical methods for the synthesis of ammonia and urea, toxic and dangerous chemicals can be replaced with clean electrons. Furthermore, the efficiency and selectivity of the reactions can be tuned by the applied potential, and more importantly, the energy used can come from renewable sources like wind or solar [2].In this talk, I will show the recent advances from our group in the development of catalysts for the electrocatalytic synthesis of ammonia and urea (as for example Cu2O and CuRh) and the reaction mechanism when using nitrate as a substrate [3].

Comparative analysis of energy-efficient air conditioner based on brand

The availability of numerous air conditioners in the market with various brands and types often leads consumers to be unaware that the purchased air conditioner may be inefficient in terms of energy usage. This research aims to determine the most energy-efficient air conditioner based on the brand of air conditioners available in the market. The research method consists of four stages: data collection, data preprocessing, data analysis, and interpretation of results and conclusions. The data used in this study was obtained from the database of the Directorate General of New, Renewable, and Energy Conservation (EBETKE), which consists of 11 AC brands sold in the market. Data analysis was performed using data distribution analysis techniques, standard deviation calculations, and correlation analysis between variables, such as the Pearson's correlation coefficient. The results of this study show that the AC brand with the highest average efficiency value is Mitsubishi Electric, with a value of 16.36 Energy Efficiency Ratio (EER), while the AC brand with the lowest average efficiency value is GREE, with a value of 5.640 (EER). Each AC brand has a different average efficiency value, with significant variations. From the correlation heatmap results, the AC power does not appear to significantly affect the AC efficiency value, where AC with lower power tends to have higher efficiency values, but there are also AC with high power and high efficiency values. Additionally, the cooling capacity value also appears to have a small effect on the AC efficiency value, where AC with lower cooling capacity tends to have higher efficiency values. However, some AC brands have high cooling capacity values but also have high efficiency values. This study also shows a moderate correlation between the AC efficiency value and the AC's annual energy consumption value, where AC with higher efficiency values tends to have lower annual energy consumption values.

Challenges of decarbonizing global maritime container shipping toward net-zero emissions

Responsible for the most significant part of the world’s burning of marine fossil fuels and shipping emissions, global maritime container shipping is under decarbonization pressure. This paper develops an integrated framework of bottom-up emission estimation and upscaling pathway analysis (BEEPA) to measure global maritime container shipping emissions from 2015 to 2020, and project possible pathways toward carbon neutrality by designing typical decarbonization scenarios. The result shows that global total seaborne container emissions fluctuated from 2015 to 2020 with a maximum value of 264 Mt, and the average annual energy consumption is 77.7 Mt (heavy fuel oil-equivalent). Container traffic to/from Asian ports generate the largest volumes of shipping emissions, accounting for about 55% of the global total. Under the most stringent scenario, container shipping emissions peak in 2025 and then quickly decline to 19.6 Mt in 2050, nearing the International Maritime Organization’s goal of reaching net zero emissions by or around 2050. Energy efficiency improvements contribute to emission reduction in the near term, but the trade growth impact still predominates in the shipping emission increase. With the maturity of infrastructural development and technological innovation, the energy transition would be the largest contributor emission reductions over the medium to long term.

Single- and double-inlet PV curtain wall systems using novel heat recovery technique for PV cooling, fresh and supply air handling: Design and performance assessment

Building integrated photovoltaic (BIPV) technology has emerged as a promising solution for serving electricity and heat demands in buildings. However, PV overheating causes reduced production, increased space cooling load, and stagnation damage. To address overheating and save energy in air conditioning, this study proposed novel single- and dual-inlet ventilation PV curtain wall systems (SVPV and DVPV). In summer, the building exhaust is introduced into the channel to strengthen PV cooling, while incoming fresh air is used to preheat dew-point air. In winter, warm exhaust within the channel decreases heat loss through the facade and then raises the fresh air intake temperature. Mathematical models were developed for the systems, and a comprehensive performance evaluation criterion (PEC) was defined. Economic analysis was conducted using simple payback (SP) and net present value (NPV) models. Additionally, the impact of ambient temperature and solar radiation on system performance was investigated. The case study demonstrates that SVPV and DVPV reduced annual energy consumption by 957.23 kWh (28.07%) and 910.97 kWh (26.72%), respectively, compared to a conventional non-ventilated system. SVPV slightly outperformed DVPV, with an average PEC of 0.556 and 0.544, respectively. This study provides valuable insights for operational strategies and future large-scale promotion of BIPV applications.

Modeling the Impacts of Filter Fouling on Energy Consumption

The use of higher efficiency particulate air filters in central heating, ventilating, and air-conditioning (HVAC) systems to improve indoor air quality (IAQ) in homes is continuing to increase. However, as filters are loaded with collected particulate matter and dust, the pressure drop will increase and lead to a variety of direct and indirect energy impacts. The magnitude of energy impacts on fouled, or dirty, filters is not yet known. Therefore, this paper explores the energy impacts of fouled filters on new energy-efficiency homes in multiple climates around the United States by performing whole building energy simulations using BEopt and EnergyPlus. Relevant inputs include filter pressure drop, total pressure drop, HVAC airflow rate, fan efficiency, heating and cooling nominal capacity, and rated airflow rate. The results indicate that annual energy consumption generally increases for permanent split capacitor (PSC) and electronically commutated motor (ECM) fans as the filter gets loaded or dirty over time, although the energy impacts are smaller for ECMs.

A novel hybrid process design for efficient recovery of hydrophilic ionic liquids from dilute aqueous solutions

AbstractIonic liquids (ILs) have received much attention in both academia and industries due to their superior performance in many applications. Efficient recovery/recycling of ILs from their dilute aqueous solutions is essential for the acceptance and implementation of many IL‐based technologies by industry. In this work, a practical and cost‐effective hybrid process design method that combines aqueous two‐phase extraction, membrane separation, and distillation operating at their highest efficiencies is proposed for the recovery of hydrophilic ILs from dilute aqueous solutions. The application of this hybrid process design method is illustrated through case studies of recovering two hydrophilic ILs, n‐butylpyridinium trifluoromethanesulfonate ([C4Py][TfO]) (CAS number: 390423‐43‐5) and 1‐butyl‐3‐methylimidazolium chloride ([C4mIm][Cl]) (CAS number: 79917‐90‐1), from their dilute aqueous solutions. For the recovery of 10 wt.% [C4Py][TfO] from aqueous solution, the hybrid process using (NH4)2SO4 as the salting‐out agent could reduce the total annual cost (TAC) and energy consumption by 57% and 91%, respectively, compared with the pure distillation processes. In the case of recovering 10 wt.% [C4mIm][Cl] from aqueous solution, the reduction in TAC and energy savings of the hybrid process with salting‐out agent (NH4)2SO3 could reach 49% and 87%, respectively, compared with the pure distillation process. Furthermore, uncertainty analysis through Monte Carlo simulations show that the proposed hybrid process design is more robust to uncertainties in energy prices and other material (e.g., equipment and solvent) costs.

Vacuum Insulation Panel: Evaluation of Declared Thermal Conductivity Value and Implications for Building Energy

Policymakers regularly implement stricter building energy-efficiency codes towards curtailing building energy use. Inevitably, super-insulating materials such as Vacuum Insulation Panels (VIPs) are essential to satisfy such codes. VIPs have been applied to buildings for over two decades now, with many lessons learned. Generally, the thermal conductivity values of VIPs often reported in the literature are the center-of-panel thermal conductivity (λcop) and effective thermal conductivity (λeff), factoring thermal bridges. However, there are other indexes, such as λ90/90 (declared value in the 90% percentile with a confidence of 90%) and λcop,90/90,aged (factoring aging), that increase consistently and reliably in the declared thermal conductivity value for VIPs. These indexes are scarcely computed and hardly reported. The main aim of this study was to examine the different declared thermal conductivity values of VIP-based guidelines, such as draft ISO DIS 16478, and evaluate their implications on annual building energy consumption. The main study constitutes four parts: (1) experimental evaluation of the thermal properties of pristine and aged VIP samples, (2) computation of thermal conductivity indexes, (3) numerical investigation of thermal conductivity indexes based on a reference building, and (4) related building energy implications. The mean λcop for 10 VIP samples was 0.0042 W/(mK) and increased to 0.0073 W/(mK) for λ90/90, bridge, aged. Results show a significant bearing on building energy performance of as much as 2.1 GJ.

The Influence of Pandemic Lockdowns on Municipal Wastewater Quality as a Consequence of Not Discharging Food Waste from Restaurants

The use of food waste disposers in gastronomical facilities influences municipal wastewater composition. Ground food waste poses problems in the operation of the sewerage network and generates high electric energy consumption in wastewater treatment plants (WWTPs). This study aimed to determine, for five towns with a PE (Population Equivalent) ranging from 4000 to 220,000, the volumes of catering waste discharged to the WWTPs. The towns differed in the number of inhabitants, beds in hotels, and catering places. The calculations were undertaken based on data received from the operators of the WWTPs. The pollutant concentrations in 2019 were compared with data from the “pandemic” year—2020. The loads of catering waste entering the sewerage system in 2019 ranged from 32.7 to 1062 tons. In the town with the largest tourist base, the BOD (Biochemical Oxygen Demand) value in 2020 accounted for 62.3% of the 2019 value. In the largest town, the annual energy consumption for food waste treatment could be up to 2,539,770 kWh. If the waste was fermented, up to 1,376,650 m3 of methane could be obtained. There is a strong need to implement a collection system for food waste from catering facilities, and the fermentation of this waste to produce methane, which can be used for energy purposes.

Towards Net-Zero Energy Consumption with Near Net-Zero Initial Cost: A Case Study from Georgia, USA

This research presents a case study of a single-family home in Georgia, United States, that achieves near net-zero energy costs for the heating, ventilation, and air conditioning (HVAC) system with near-zero additional capital investment. Building information modeling (BIM), energy analysis, and practical common construction practices were integrated to trade-off between design and construction alternatives to achieve these results. An accelerated number of publications addressed net-zero energy buildings (NZEB). Much of this research addresses means and methods to make buildings produce as much energy as they consume (net-zero site or building energy) or make buildings produce energy and sell it to offset the buildings’ energy bills (net-zero cost). However, NZEBs still constitute a small fraction of the building industry, which is mainly due to higher initial costs, significant deviations from common construction practices, or altering common building operations and comfort levels. In this research, a practical approach for achieving NZEB was tested and used in constructing a single-family home. BIM software that generates annual energy consumption with every design alternative was used during the design and construction phases of this home. The BIM model was also used to generate building materials quantities to estimate the initial construction cost. In this case study, the initial construction cost of the selected design was less than that of comparable homes in the same area. The post-occupancy evaluation showed that the annual energy consumption related to heating and cooling was 72% less than that of comparable homes in the same area. Energy consumption related to hot water consumption was 21% less, and energy consumption for lighting was reduced by 22%. In conclusion, general design guidelines and lessons learned are established to help the residential building industry adopt energy-efficient design and construction approaches to reduce energy consumption in homes without increasing the listed prices of homes.

Performance investigation of an innovative solar heating unit for a powered self-sustained solar dryer

Drying food is an efficient way to prevent crop decay. However, drying techniques are known to be intensive processes in which the energy required is usually met by fossil fuels, the main sources of greenhouse gas emissions. Thus, the development of a solar-powered sustainable drying system is not only crucial for zero CO2 emissions, but also for improved energy efficiency. This study performs a comparative analysis of four solar collectors used as heating units in an indirect forced convection solar dryer. The collectors evaluated were a flat solar collector, two solar air collectors with latent thermal storage (CaCl26H2O and paraffin), and a novel heating unit combining the latter two collectors. This study conducted a comprehensive 4E analysis, evaluating the performance of the collectors through energetic, exergetic, economic, and environmental assessments. The results showed that the pioneering heating unit caused a 30 °C increase in nocturnal temperature compared to other collectors. It demonstrated an annual energy consumption of 640 kWh/year and an energy payback period of 2.5 years. The environmental analysis revealed a significant CO2 reduction of 39 tons. Overall, the proposed heating unit allows a more sustainable and cost-effective drying process while reducing greenhouse gas emissions and promoting energy conservation.

Influence of Balcony Glazing on Energy Efficiency and Thermal Comfort of Dwellings in a Dry Mediterranean Climate within a Warm Semi-Arid Climate

This paper analyses, as a case study, various balcony glazing arrangements in a typical tourist apartment building on the Mediterranean coast of south-eastern Spain, and their effects on the energy performance. The glazing of terraces has been very common in this type of flat over the last 40 years. The objective is to determine qualitatively and quantitatively how the glazing of terraces in such buildings influences their energy efficiency and indoor thermal comfort, considering the specific characteristics of the dry Mediterranean climate (BShs) within a warm semi-arid climate (BSh). The scientific novelty of the work consists of demonstrating that the installation of glazed enclosures on terraces allows the houses to be heated for free in winter, taking advantage of the greenhouse effect, and allows excess heat to be dissipated in summer by using natural ventilation. The results of the work enable the determination of appropriate terrace glazing solutions to improve the energy efficiency and thermal comfort of the dwelling, obtaining a reduction of more than 58% in annual energy demand and annual energy consumption. The work demonstrates the advantages that glazing systems for terraces can have in improving the energy efficiency of houses by using systems like glass curtains.

TRNSYS simulation study of the operational energy characteristics of a hot water supply system for the integrated design of solar coupled air source heat pumps

To address the issues with solar water heating systems taking up a lot of space, unstable hot water supply, air source heat pumps susceptible to frost in the winter, and low energy efficiency. The TRNSYS tool is employed in this work to simulate a solar-coupled air source heat pump system. The heat pump operation is first investigated using the inverse Carnot cycle. The performance coefficient is then calculated by the second law of thermodynamics without considering the pipeline's pressure drop and heat loss. The output temperature of the hot water that the heat pump circulates is then determined. The daily hot water needs can be estimated roughly based on information about solar radiation. The heat balance equation for flat plate solar collectors was used to compute the intensity of solar diffused radiation. The Berlage calculation was used to determine the solar radiation received on the collector's surface. After a qualitative analysis of the heat from the heat source, the efficiency of the linked heat pump and the conventional air source heat pump was compared. Analyzing the water temperature change graph for each month's data reveals that the system can achieve 50 °C during the water supply time each month. The heat pump's annual energy consumption is 6252.01 kWh, while the system's annual energy consumption is 9100.47 kWh. The study findings may be used as a guide to improving the design and management of the whole system. In addition, they may improve the solar water supply system's performance.

Effects of alkali-activated slag binder and shape-stabilized phase change material on thermal and mechanical characteristics and environmental impact of cementitious composite for building envelopes

A tremendous quantity of energy has been used in the building and a huge amount of CO2 emitted to maintain comfortable indoor temperatures. In order to lower existing level of CO2 emissions, using eco-friendly alternative binders instead of ordinary Portland cement (OPC) and improving buildings’ energy efficiency are indispensable. The thermal characteristics of cementitious composite have been improved by the use of phase change materials (PCMs) via its latent heat capacity. PCMs can also be incorporated with alkali-activated binding materials of industrial by-products such as alkali-activated slag (AAS), which can result in an efficient carbon reduction compared to the use of ordinary Portland cement (OPC) as a binder. To better comprehend the practical feasibility of AAS in PCM-incorporated composites as an alternative building component, it is necessary to study the one-part AAS system holistically by assessing its fundamental material characteristics, environmental impact (CO2 emission), and energy efficiency. This work uses an experimental-computational method and a case study to evaluate the effects of one-part AAS binder and shape-stabilized PCMs on thermal and mechanical properties and environmental impact. The experimental results demonstrate that AAS binder can reduce thermal conductivity by up to approximately 20% compared to the OPC case. Incorporating thermal energy storage aggregate (TESA) in the AAS binder can further decrease the thermal conductivity. In addition, the AAS-based composite can significantly reduce CO2 emissions by more than 10% than the OPC-based case due to the improved thermal properties and the consequent reduction in carbon footprint from raw materials and annual energy consumption. The results of this study infer the feasibility of AAS binder and TESA as eco-friendly, energy-saving cementitious composites for building envelopes.
