Abstract [en]

In an era of rapidly advancing lighting technology and evolving public library roles, this study introduces a groundbreaking strategy for human-centric and integrative lighting asset management. Embracing both visual and non-visual effects, “integrative lighting” aims to enhance users’ physiological and psychological well-being. Despite technological progress, notably with LEDs, current asset management often lags, relying on reactionary measures rather than proactive strategies. As public libraries transform into dynamic learning hubs, the significance of indoor lighting, impacting both physical health and holistic well-being, cannot be understated. Yet, many existing solutions are based on controlled lab tests, bypassing the diverse real-world needs of public libraries. Aiming to explore and develop human-centric and integrative lighting asset management strategies to optimize lighting environments in public libraries, this research offers a cohesive approach encompassing context identification, a management framework, and a maturity assessment model. Additionally, this study highlights the synergy between the role of the lighting asset manager, ISO 55000 principles, and these foundational strategies. This holistic approach not only reinvents lighting in public libraries but also aligns it with the broader Sustainable Development Goals (SDGs), advocating for light as a conduit of comprehensive human betterment. The current study is primarily qualitative in nature. While this study is based on public libraries in Nordic countries, the implications and findings can be of interest and value to a broader international audience.

Abstract [en]

Traditional asset management of lighting systems typically focuses on functionality, cost, and lifespan. In contrast, a human-centric approach prioritizes social sustainability and user well-being by ensuring lighting assets “provide the right light at the right time” for diverse activities. Light-emitting diode (LED) bulbs, known for energy efficiency and longevity, have become a preferred choice, yet public libraries often struggle to manage these assets sustainably, remaining in a reactive “fix/replace when it breaks” stage. Current predictive methods, such as artificial intelligence and machine learning, rely on laboratory data that often overlook real-world contexts, leading to performance gaps. This paper presents a context-driven, human-centric methodology for LED prognosis and maintenance strategies in public libraries, employing limited degradation data from LED testing. Advanced analytical techniques, including Markov Chain Monte Carlo (MCMC) and Deviance Information Criterion (DIC), support a shift from function-based to performance-based reliability assessment. By incorporating Mean Time of Exposure (MTOE) and Critical Integrated Levels (CILs), the approach defines optimal maintenance inspection intervals. This research enhances sustainable LED lighting management in public libraries, offering a framework adaptable to broader applications and aligned with human-centric goals.

Abstract [en]

As more companies strive for net-zero emissions, mitigating indirect greenhouse gasemissions embedded in value chains—especially in logistics activities—has become a critical priority.In the European logistics sector, sustainability and energy efficiency are receiving growing attention,given the sector’s intersectional role in both transportation and construction. This transition towardlow-carbon logistics design not only reduces carbon emissions but also yields financial benefits,including operational cost savings and new market opportunities. This study examines the impactof passive design strategies and low-carbon technologies in a Swedish logistics center, assessedusing the low-carbon design criteria from the BREEAM International standard, version 6. Thefindings show that passive energy-efficient measures, such as the installation of 47 skylights fornatural daylighting, reduced light power density in accordance with AHSHARE 90.1-2019 and theintegration of free night flushing, contribute to a 23% reduction in total energy consumption. Inaddition, the integration of 600 PV panels and 480 batteries with a capacity of 268 ampere-hours and13.5 kWh storage, operating at 50 volts, delivers a further 56% reduction in carbon emissions. Byoptimizing the interaction between passive design and active low-carbon technologies, this researchpresents a comprehensive feasibility analysis that promotes sustainable logistics practices whileensuring a future-proof, low-carbon operational model.

Abstract [en]

Most lighting is only designed to meet the visual needs in most public libraryenvironments in Sweden. Although lighting-related impacts are relevant to six Unite Nationssustainability goals, some important lighting considerations, such as circadian phase disruption,mode and productivity impact, and energy-efficient operation, are missing in current lightingoperating practices. Moreover, most of the current lighting asset management practice in publicbuildings remains “fix it if only it breaks”. With respect to people-centric health factors, visualindex, and lighting asset energy-efficient operation, this study sublimates lighting into a newperspective. Finally, the suggested comprehensive lighting operating strategies integratingdigital twins can help designers and operators in defining the optimal design/control strategy inpublic-built environments, like public library. Digital twin-based decision-making is expected tobe applied to lighting design and control in public spaces that improves visual acuity and comfort,positively impact mood and productivity, and provides recommendations on engagementprinciples under Environment Social Governance (ESG) framework to asset manager/operators.

Abstract [en]

The COVID-19 outbreak is exacerbating uncertainty in energy demand. This chapter aims to investigate the impact of the confined measures due to COVID-19 outbreak on energy demand of a building mix in a district. Three levels of confinement for occupant schedules are proposed based on a new district design in Sweden. The Urban Modeling Interface tool is applied to simulate the energy performance of the building mix. The boundary conditions and input parameters are set up according to the Swedish building standards and statistics. The district is at early design stage, which includes a mix of building functions, i.e., residential buildings, offices, schools, and retail shops. By comparing with the base case (normal life without confinement measures), the average delivered electricity demand of the entire district increases in a range of 14.3–18.7% under the three confinement scenarios. However, the mean system energy demands (sum of heating, cooling, and domestic hot water) decrease in a range of 7.1–12.0%. These two variation nearly cancel each other out, leaving the total energy demand almost unaffected. The result also shows that the delivered electricity demands in all cases have a relatively smooth variation across a year, while the system energy demands follow the principle trends for all the cases, which have peak demands in winter and much lower demands in transit seasons and summer. This chapter represents a first step in the understanding of the energy performance for community buildings when they confront with this kind of shock. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.

Abstract [en]

The COVID-19 pandemic has catalyzed global efforts toward transitioning to a sustainable society, driving rapid innovation in building technologies, working practices, building design, and whole life cycle environmental impact consideration. In this pursuit, this study explores the enduring impact of these on an alternative ventilation approach for both existing building renovations and new building implementations. Comparing displacement ventilation to mixed-mode ventilation in a Finnish office building with varying occupancy densities, this study examines indoor air quality (IAQ), thermal comfort, total building energy performance, and embodied carbon. The findings reveal that the basic case of mixed ventilation has a specified system primary energy value of 38.83 kWh/m2 (with 28 occupants) and 39.00 kWh/m2 (with 24 occupants), respectively. With the displacement ventilation alternative, it reduces this by 0.3% and 0.1%, enhancing thermal comfort and decreasing turbulence as well as having a marginal decrease in embodied carbon. In general, the study offers three-fold contributions: insights into post-pandemic office mechanical ventilation design with an emphasis on sustainability and ecological footprint considerations, a concrete case study addressing climate action and human-centric IAQ design, and a multifaceted analysis using the Environmental, Social, and Governance (ESG) paradigm, contributing to the groundwork for associated future research and policy progress.
