Architectural and environmental strategies towards a cost optimal deep energy retrofit for mediterranean public high schools

Energy Reports, Journal Year: 2023, Volume and Issue: 9, P. 6434 - 6448

Published: June 16, 2023

Deep energy retrofit of the existing public stock is a crucial strategy to promote environmental targets at national and EU private levels, as required by Directives. The article presents deep renovation focused on high school buildings. research carried out in sample buildings Catalonia which their possibilities rehabilitation are analysed, developing toolkit for prioritizing intervene standardization possible improvement measures Such methodology specifically developed replicability Mediterranean schools, model applied specific case enquiry climatic zone Cfa according Köppen (and equivalent Zone D3 Spanish level Technical Building Code), accordance with volume constructive characteristics replicable large schools built same period (70's). Despite being that over 50 years old, demolition not considered appropriate but it preferred gradually improve construction elements facilities system throughout lifespan. It worth noticing current thermal discomfort low air quality particularly during summer months when overheating can be significant issue, given absence an active cooling system. should noted technical aspects evaluated this first phase those meet definition nZEB building under cost optimal methodological framework: (1) prioritize demand reduction (minimizing heating aim penalizing decisively enough require new implementation refrigeration equipment avoid overheating), (2) followed optimization installations' consumption relation performance and, finally, (3) promoting renewable energies. Next, proposed discriminate intervention out, strategy, considering such life cycle building. This validated its application representative study shown. Four key strategies followed: inspection evaluation reference scenario, establishing strategic vectors official nZEB, Considering analysis interventions assess impact beyond use phase, (4) economic between investment benefit bill respect benefit, order guarantee renovation. aims show solutions, seen from point view building, cease relevant all phases (LCA) introduced.

Geometry optimization in the schematic design phase of low-energy buildings for all European climates through genetic algorithms

Sustainable Cities and Society, Journal Year: 2024, Volume and Issue: 112, P. 105639 - 105639

Published: July 8, 2024

The ongoing transition towards resilient and energy-efficient cities highlights the design of new buildings as a critical concern. With increasing urbanization in Europe concurrent need for energy reduction decarbonization, it is crucial to address efficiency construction sector, by recently adopted European Energy Performance Building Directive. In this context, article focuses on role geometry optimization schematic phase low-energy buildings, considering among different climates. Indeed, study aims propose multi-objective approach (using genetic algorithm) optimize "genes" building, e.g., shape, proportions, orientation window-to-wall ratio residential early phase, cut off significant portion consumptions. objective thus minimize heating cooling needs based best combination above-mentioned genes. research investigates optimal solutions across various climates Köppen-Geiger classification, comparing results 19 with varying climate. findings confirm that are strongly influenced climate conditions their location. study, which comprehends almost 250.00 configurations, assesses, expected, strong effect cross-shaped performing 17 over sites investigated. solution each site leads total comprised between 4.58 kWh m-2 y-1 Porto 19.84 Goteborg, an average all 12.45 y-1. provides valuable insights professional aiding them making informed decisions during achieve adapted specific

The LES Project (LES-Llavor Energètica i Salut. Del cole a casa la societat, in English: Energy and Health Seed. From school to home society) is seen as an opportunity increase the visibility of role science women scientists their actual contexts present architectural research essential mitigating climate change improving people’s health. goal this was reach greatest range people possible through intergenerational transfer. However, main receptors drivers were students aged between 8 10 years old who responsible for transmitting energy environmental conditioning concepts interrelations with strategic performance buildings. Awareness raised scientific workshops implemented primary schools that had air quality deficiencies opportunities, extrapolated housing. Two different socioeconomic districts (vulnerable middle-income families) selected strategy provide details about perceptions benefits both schools’ families. results experience highly satisfactory. Children from interested ready understand transfer key efficiency health improvement transformation buildings surrounding them. dissemination project social awareness reached two entire educational community (students, teachers, families all society). Currently, we are working on second stage will allow broad volume replicability workshops, schoolteachers taking lead these actions.

Carbon emission reduction in public buildings of extreme cold regions: A study on enclosure structure and HVAC system parameter optimization

Energy Science & Engineering, Journal Year: 2024, Volume and Issue: 12(6), P. 2676 - 2686

Published: May 20, 2024

Abstract The implementation of strategies aimed at curtailing energy consumption and carbon emissions in buildings is paramount importance. Priority should be accorded to the reduction embodied from construction materials operational during usage phase. A public building situated an extremely cold region chosen as subject this study. An initial investigation conducted into impact various enclosure structure on carbon. different heating, ventilation air conditioning (HVAC) systems total are studied well. findings indicate that amalgamation W3 + R G4 H4 culminates least emissions. Upon establishing foundational scheme for building, optimization (nondominated sorting genetic algorithm II [NSGA II] Criteria Importance Through Intercrieria Correlation [CRITIC]) parameters initiated examine optimal building's structure. reveal a decrease heat transfer coefficient could trigger increase This attributed fact production process these potentially outweigh observed Further adjustments were also made HVAC system buildings. within context buildings, given presence utilizes solar both heating cooling American Society Heating, Refrigerating Air‐Conditioning Engineers, Inc. 6 climatic zone, efficiency can exert significant influence operations reduction.
