Solution Renovation ā typological guidelines for the energetic retrofit of multi housing residential buildings in Geneva
The project āSolution Renovationā aims to promote the energy transition and renovation of existing multi housing buildings in canton Geneva by providing incentives and assistance to owners to trigger renovation decisions. Solution Renovation offers to the ownersā project guidelines (meta-diagnostics) for their buildings, in relation to their renovation potential, based on a typological analysis of structures and envelopes. The building population has been classified into nine different faƧade typologies. For each typology 1 or 2 detailed refurbishment scenarios have been developed, with cost and energy saving estimations to serve as guidelines to owners
Norme ISA 520 : Outil dāapplication dāaudit dans lāutilisation de proceĢdures analytiques
Ce meĢmoire part de la probleĢmatique et du constat du rapport de le CSSF de 2015 quāil existe des lacunes lors aĢ la reĢalisation de proceĢdures analytiques de substance pour estimer les revenus dāune entiteĢ. Nous avons donc eĢtabli comme question de deĢpart: Ā« Comment lāauditeur peut-il ameĢliorer lāefficaciteĢ de la mise en Åuvre et de la reĢalisation de proceĢdures analytiques comme tests de substance ? Ā». Pour reĢpondre aĢ cette question de deĢpart, nous avons deĢfini les diligences pour lāauditeur dans lāapplication de SAP avec la norme ISA 520. Nous avons contextualiseĢ la place des proceĢdures analytiques dans le processus dāaudit graĢce aĢ la norme ISA 315 sur lāeĢvaluation des risques et aĢ la norme ISA 330 sur les reĢponses aĢ apporter aux risques eĢvalueĢs. Nous avons eĢgalement deĢfini les meĢthodes dāanalyse pour lāapplication de proceĢdures analytiques de substance sur les diffeĢrents cycles lieĢs au compte de reĢsultat. Nous avons, dans la dernieĢre partie de ce meĢmoire, reĢaliseĢ une analyse sur des interviews effectueĢes sur des auditeurs du cabinet Mazars afin dāeĢtablir les facteurs positifs et neĢgatifs pouvant affecter la reĢalisation de proceĢdures analytiques. Lāensemble des ces recherches et de ces interviews nous ont finalement permis de reĢaliser des outils dāaudit performants pour reĢaliser des proceĢdures analytiques de substances (SAP) sur le chiffre dāaffaires, les frais geĢneĢraux, le cycle du Payroll, les charges dāamortissement et les charges et produits financiers.Master [120] en sciences de gestion, UniversitĆ© catholique de Louvain, 201
LāeĢvaluation de lāimpact dāune nuit de privation de sommeil sur les capaciteĢs de prise de perspective visuelle
Ce meĢmoire a pour objectif dāeĢvaluer les effets dāune nuit de privation de sommeil sur les capaciteĢs de prise de perspective visuelle. LāeĢtude suit un design Within- Subjects : les performances de 20 participants (M = 24.2 Ā± 2.73 ans) ont eĢteĢ compareĢes apreĢs une nuit de privation de sommeil et apreĢs une nuit de sommeil normale passeĢe chez eux. Une eĢtude reĢcente (Deliens, Stercq, Mary, Slama, Cleeremans, Peigneux et Kissine, soumis) utilisant une taĢche de deĢtection de sarcasme a deĢjaĢ mis en eĢvidence que la privation de sommeil pouvait affecter certaines capaciteĢs de prise de perspective au delaĢ dāun simple ralentissement global des performances. Nous nous sommes deĢs lors demandeĢs si nous constaterions des effets similaires au niveau des performances aĢ des taĢches de prise de perspective visuelle. Nous avons inclus deux taĢches de perspective dans notre eĢtude. La premieĢre neĢcessite un jugement concernant un nombre de spheĢres visibles aĢ lāeĢcran selon notre propre perspective ou selon celle dāun avatar (adaptation de la taĢche de Samson, Apperly, Braithwaite, Andrews et Bodley Scott, 2010). La seconde, neĢcessite un jugement concernant lāapparence dāun chiffre selon notre propre perspective ou selon celle dāun avatar (adaptation de la taĢche de Surtess, Butterfill et Apperly, 2012). Lors de preĢceĢdentes eĢtudes, il a eĢteĢ prouveĢ que les capaciteĢs de prise de perspective visuelle pouvaient eĢtre affecteĢes par des facteurs transitoires tels que lāhumeur (Bukowski et Sanson, 2015) et la disponibiliteĢ des ressources cognitives (Qureshi, Apperly et Samson, 2010) et nous avons donc choisi dāinclure aĢ nos analyse une eĢvaluation de lāeĢtat affectif des sujets et de leur capaciteĢs exeĢcutives.Master [120] en sciences psychologiques, UniversitĆ© catholique de Louvain, 201
Optimising densification and renovation of the building stock in Switzerland
Densification-refurbishment of existing buildings could be an interesting solution both to improve energy performance and to contribute to the densification of urban areas, two declared objectives of recent legislation at the Swiss level. However, so far, operations of this kind have not been a resounding success. The eREN2 study demonstrated why : mainly a lack of economic interest. This paper is to be seen as an extension of the eREN2 study, exploring several options for making these operations financially attractive and the consequences of the decline of return on investment on their attractiveness. The outcome is that alternative options such as densification-refurbishment conceived as partial real estate development projects and the diminishing expectations return on investment on the real estate market could result in densification-refurbishment projects being a very valuable solution in the future both financially and in terms of energy saving
Commune rƩnove ::putting municipalities in proactive mode for the energy renovation of the building stock
The canton of Geneva declared the climate emergency in 2019 and published its energy master plan in 2021. This has given a major impulse to several programs to support and encourage the energy refurbishment of the building stock in the canton, implemented by the cantonal energy office, Services Industriels de GenĆØve (SIG) and the Haute Ć©cole du paysage, dāingĆ©nierie et architecture de GenĆØve (hepia). Among the projects launched is the āCommune rĆ©noveā program, which aims, to encourage municipalities to take proactive steps to target owners of priority buildings for renovation and to help them implement ambitious energy refurbishment projects. In this context, hepia has developed tools to enhance municipalitiesā level of knowledge of the building stock on their territory and support them in targeting and informing the buildingsā owners about potential refurbishment scenarios. These tools include typology guidance sheets, a typological census covering the whole canton, and interactive maps, that are used by local authorities in their approach to owners of multi-family buildings, which represent the most important source of energy savings
Digital steering tool for real estate owners in the era of energetic transition
Real estate portfolio owners face a huge challenge with the combination of the necessity to refurbish ageing buildings inherited from the booming construction period of 1950 to 1980 and the need for decarbonization of the heating systems of the building stock to preserve the environment. Many property owners facing this challenge do not have a clear overview of their portfolio and do not know where and how to start renovation work on their existing build-ings, and lack basic instruments to help them in the strategic planning phase. A very simple and transparent digital tool has been developed by the HES-SO /HEPIA, Ge-neva, on behalf of a real estate foundation in Geneva to give its board a clear vision on the Foun-dation assets and help it to define intervention priorities amongst its building. This tool, based on a multicriteria and interdisciplinary approach, is be one of the instruments that can help real estate portfolio owners to tackle the challenge they are facing today, in a simple and autonomous way
Strategien zur Sanierung von GebƤudehĆ¼llen
Die energetische Sanierungsrate ist nach wie vor tief. Wird saniert, sind Einzelmassnahmen ohne Gesamtkonzept die Regel. Das Projekt Ā«eRenĀ» der Fachhochschule Westschweiz HES-SO skizziert gesamtheitliche Strategien fĆ¼r zehn reprƤsentative GebƤude
eREN energetic refurbishment ::a global approach for the building envelope
Buildings energetic retrofit is key to the Swiss Ā« 2050 Energetic strategy Ā», but the refurbishment rate is low. eREN [1] has analysed the 20th century multi-dwelling housing stock in Western Switzerland from a constructive point of view and developed refurbishment scenarios for the envelope of 10 buildings. The goal is to achieve balanced solutions between energy efficiency, constructive feasibility, building physics, cost, architecture and use value. Our investigation shows that āwrappingā is not the only solution to meet the standard, whatever the solution it is technically complex, the cost are high but could be mitigated, projects must be led by qualified professionals and interdisciplinarity must be actively promoted
