In Australia, various policies and private-sector initiatives have been introduced to assist the construction industry in reaching its environmental impact reduction potential. The National Australian Built Environment Rating System (NABERS) and Green Star, two widely adopted building certification systems, have targeted this gap, with Green Star mandating design verification during construction and NABERS monitoring operational performance. This study aims to assess the effectiveness of these certification systems in reducing the performance gap in Australian office buildings by quantifying the predicted and actual performance of certified assets. Predicted energy usage data was collected from Green Star submissions of 176 office buildings and matched and compared with NABERS Energy ratings reporting performance during operation. The results were discussed with a group of building certification specialists, who provided insights on these outcomes and approaches towards narrowing the remaining performance gap. Overall, 65% of the cases achieved or exceeded their predicted NABERS Energy performance targets. The cases increased to 75% when considering the buildings’ highest NABERS Energy rating during the period of analysis and to 94% in cases that included NABERS Commitment Agreements (CA)—where developers are held accountable by contract to meet a specific performance target. These results suggest that the use of certification systems, such as the ones evaluated in this study, can contribute to closing the energy performance gap in Australia by setting buildings up for high-energy performance through design and operation.</div></div>","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"341 ","pages":"Article 115813"},"PeriodicalIF":6.6,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2035, the total carbon emission from building operations and prefabricated building fabrication in the system will account for 74.59% of the total predicted carbon emission.

Integrating onsite renewables is vital for NZEBs, and solar photovoltaic (PV) is widely adopted for its geographical flexibility. However, it demands a battery energy storage system (BESS) or grid support to tackle its natural intermittency, which invokes an affordability-reliability trade-off. Therefore, multi-objective grey wolf optimization (MOGWO) with net-zero focus has been employed in this study to optimally size the PV-BESS for different buildings with levelized cost of energy (LCOE), loss of power supply probability (LPSP), and excess energy index (EEI) as minimization objectives. Despite attaining a competitive compromise solution, EEI and LPSP often become inevitable. To address this issue, an excess energy transfer framework between the DC buses is facilitated and analyzed. The benefits achieved from the proposed framework motivated the optimal sizing of an energy-intensive building while utilizing excess energy transfer from neighboring buildings. This collaborative energy transfer approach cuts BESS requirements by 41 %, lowers LCOE by 37 %, reduces LPSP by 8 %, and eases grid burden by 6 % annually for the considered building compared to the scenario without excess energy transfer. Further, attempting simultaneous optimal sizing of all considered buildings ensures net-zero attainment, while providing similar cost and energy benefits. Hence, incorporating excess energy transfer from the planning stage enables urban high-rise buildings, even with limited rooftop space for PV installation, to become NZEBs economically, thus fostering sustainable power generation across urban environments.</div></div>","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"341 ","pages":"Article 115807"},"PeriodicalIF":6.6,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143924325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, previous research often faced challenges in acquiring measured data that reflected control setpoint variations, leading to the use of simulation-derived data as training data for predictive models. Additionally, performance data provided by manufacturers for the simulation modeling of direct expansion air handling unit (AHU) systems like electric heat pumps (EHP)-AHU was based on experimental data using variable refrigerant flow systems connected to cassette-type and duct-type indoor units. This approach inadequately captured the heating and cooling performance and energy consumption characteristics of EHP-AHU systems. This study was conducted as a foundational investigation aimed at addressing the limitations of previous research and supporting the development of an optimal control algorithm for the EHP-AHU system. To this end, a multi-calorimeter experiment was carried out to quantitatively evaluate the cooling performance under varying supply air temperature conditions and to assess the feasibility of algorithm development through regression analysis. In addition, to develop a prediction-based optimal control algorithm, this study aimed to construct a deep neural network (DNN)-based prediction model capable of accurately capturing the dynamic variations in operating conditions, including outdoor air temperature, thermal load, and humidity, under real-world environments. Experimental results demonstrate that as the supply air temperature increases, the low pressure of the EHP-AHU system rises, leading to a reduction in the power consumption of the outdoor unit. Depending on outdoor conditions, power consumption reduction rates vary. For example, changing the supply air temperature from 12 °C to 14 °C and 16 °C resulted in maximum reduction rates of 20.7 % and 32.3 %, respectively. Thus, supply air temperature setpoints were identified as critical control variables for effectively reducing the power consumption of outdoor units. Using multi-calorimeter experimental data reflecting EHP-AHU system characteristics, a DNN-based power consumption prediction model was developed.
