Development of Energy Demand Profile Based on Non-Historical and Non-Energy Variables: A Headquarters’ Offices Case Study

Energies, Journal Year: 2025, Volume and Issue: 18(3), P. 605 - 605

Published: Jan. 28, 2025

Under the Positive Energy Districts framework, cities authorities must be informed of energy demand districts to design tailor-made policies and strategies promote deployment efficiency, sharing transition actions. However, diverse data sources long procedures collect because privacy permissions may result in a slow-down development these roadmaps. To overcome challenges, this paper is outcome methodology developed under UP2030 Project designed estimate profile consumptions within urban areas contribute stakeholders involved decision making processes inform them about savings potential related with use geographically delimitated areas. The was validated CIRCE’s headquarters, where yearly estimation consumption 98% real consumed. main finding study obtaining model that can usage for occupants’ comfort minimal required from citizens’ side, which will allow consider global estimations at district level fast reliable way timely manner as by efficiency standards proposed European Union.

Long-Term Building Renovation Strategies—F-TOPSIS Analysis of Solutions Applied in the Chosen European Union Countries

Buildings, Journal Year: 2025, Volume and Issue: 15(4), P. 607 - 607

Published: Feb. 15, 2025

The article analyzes long-term renovation strategies in EU member countries using the F-TOPSIS method, focusing on chosen criteria such as CO2 emission reductions, rates, energy savings, investment requirements, and overall strategy quality. High-performing countries, Finland Spain, demonstrate importance of clear targets, robust planning, substantial financial commitments. In contrast, several show gaps strategic detail or ambition, highlighting challenges achieving climate neutrality goals. methodology underscores effectiveness multi-criteria decision-making tools assessing complex strategies. findings emphasize need for harmonized metrics innovative approaches, digital like building passports.

Hybrid Predictive Maintenance for Building Systems: Integrating Rule-Based and Machine Learning Models for Fault Detection Using a High-Resolution Danish Dataset

Buildings, Journal Year: 2025, Volume and Issue: 15(4), P. 630 - 630

Published: Feb. 18, 2025

This study evaluates the effectiveness of six machine learning models, Artificial Neural Networks (ANN), Random Forest (RF), Extreme Gradient Boosting (XGBoost), Support Vector Machine (SVM), K-Nearest Neighbors (KNN), and Logistic Regression (LR), for predictive maintenance in building systems. Utilizing a high-resolution dataset collected every five minutes from office rooms at Aalborg University Denmark over ten-month period (27 February 2023 to 31 December 2023), we defined rule-based conditions label historical faults HVAC, lighting, occupancy systems, resulting 100,000 fault instances. XGBoost outperformed other achieving an accuracy 95%, precision 93%, recall 94%, F1-score 0.93, with computation time 60 s. The model effectively predicted critical such as “Light_On_No_Occupancy” (1149 occurrences) “Damper_Open_No_Occupancy” (8818 occurrences), demonstrating its potential real-time detection energy optimization management Our findings suggest that implementing frameworks can significantly enhance accuracy, reduce waste, improve operational efficiency.

Energy Efficiency, CO2 Emission Reduction, and Real Estate Investment in Northern Europe: Trends and Impact on Sustainability

Buildings, Journal Year: 2025, Volume and Issue: 15(7), P. 1195 - 1195

Published: April 5, 2025

Energy efficiency and CO2 emission reduction are key objectives related to climate change mitigation, sustainable development, energy resource management. In the Nordic context, consumption trends in both residential industrial sectors closely linked European Union policies, technological innovation, real estate investments. recent decades, development renovation of sector has become one most important factors determining changes consumption, especially buildings, which remain among largest consumers polluters. this countries’ efforts reduce emissions increase inseparable from sector’s contribution these processes, by promoting investments building modernization energy-saving technologies. However, remains a complex area where economic interests need be reconciled with environmental objectives, context EU strategies such as Renovation Wave Efficiency Directive. This article examines links between investment, efficiency, reduction, based on quantitative analysis, assess how policy measures affect Northern Europe. study uses advanced methods, including panel regression model, helps better reveal long-term dependencies dynamics. highlights importance implementing sustainability policies suggests strategic solutions that can help reconcile priorities.

Energy efficiency practices: A case study analysis of innovative business models in buildings

Energy and Buildings, Journal Year: 2024, Volume and Issue: 313, P. 114223 - 114223

Published: May 1, 2024

Over the last two decades, European Union has significantly improved its legal framework for building energy efficiency. New mandatory standards have led governments to adopt incentive measures that, in turn, encourage growth of innovative entrepreneurial practices. This study analyzes emerging business models that capitalize on efficiency industry. Thirty-seven projects − either retrofit or new construction, supported exclusively by featuring presence an individual contractor five Central and Western countries are considered. Data is collected property characteristics, environment, measures. Using Rough Set approach, analysis identifies core attributes associate differentiate case studies. They include ownership, energy-related services be provided users, duration which must involved. Additionally, other such as types work, investment costs, access monetary incentives, expected payback period allow us identify cases representing best practices each model. There remain open questions concerning where boundary between different lies long-term economic self-sustainability, regardless availability incentives.
