Simulace energetické náročnosti a reálné užívání budov / SIMULATION OF ENERGY PERFORMANCE AND REAL OPERATION OF BUILDINGSŠteffek, Libor January 2020 (has links)
This dissertation thesis primarily focuses on the experimental measurement of energy consumption of a given energy-passive family house as well as theoretical research in the field of energy calculations using computer simulations. The results of quasi-stationary and dynamic simulations, with varying computational and real-time climate data, are compared with experimental measurements. Using the dynamic calculation model, which was validated by actually measured data, the relationship between architectural design and the energy performance of the building was analyzed. The influence of selected different operating modes for heat consumption on heating, cooling, ventilation, and interior overheating is observed. The result of the mutual interaction of several input parameters of variant solutions provides the basis for optimization of the whole design.

Využití knihovny HAM-Tools pro simulaci tepelného chování rodinného domu / HAM-Tools library use for the simulation of the thermal performance of the houseZábojník, Jakub January 2015 (has links)
In terms of master’s thesis HAM-Tools library designed for MATLAB/Simulink was modified for the use in simulations of houses in the Czech Republic. Modified library and its parts were described in detail and tested by the simulation of the one-zone and two-zones models of the house. The simulations of models with same parameters were also realized in program TRNSYS. The corresponding results achieved in mentioned simulation tools were compared to each other. The one-zone model created by using HAM-Tools library is tested by the simulation of ventilating, heating, cooling, and sources of moisture. A demonstration of the practical use of the simulation is carried out in the thesis, namely by examining the influence of the insulation thickness on the thermal performance of the house (resp. its heat loss) on real atmospheric conditions. Among others, available resources of meteorological data are mentioned and compared to each other. The function for processing of the meteorological data to a file compatible with the HAM-Tools library was created. It was also created a material data file containing commonly used materials of building structures in the Czech Republic and their parameters.

Evaluation multicritères multi-acteurs de la performance des projets de rénovation énergétique : cas des copropriétés touchées par la précarité énergétique. / A multi-criteria multi-actors assessment of performance energy concerning energy projects of renovation : case of Condominium housing touched by the phenomenon of fuel poverty.Hini, Sihame 30 November 2017 (has links)
Le phénomène de la Précarité Energétique (PE) ne cesse de gagner du terrain, il concerne 20,4% de la population françaises en 2016 contre 18,4% en 2013 (ONPE ; 2016). Ce constat oblige une attention particulière à la question de la performance énergétique des bâtiments.Malheureusement, cette performance est limitée aujourd’hui à la seule question de l’efficacité énergétique, or, il faudra prendre en compte la sobriété énergétique et le comportement des acteurs pour atteindre une vraie performance. Pour ce faire, nous avons mobilisé le parc de la copropriété qui est un parc avec une gouvernance complexe où la prise de décision commune pour voter les travaux est difficile à atteindre. Afin de répondre à ce problème complexe, une démarche délibérative établissant un dialogue entre les acteurs de la copropriété (syndic, conseil syndical, copropriétaires résidents et copropriétaires bailleurs), mais aussi avec les autres parties prenantes portant des connaissances sur la rénovation énergétique des bâtiments (architecte, thermicien, chargés d’opérations ...etc.), permettrait d’une part d’accompagner les copropriétaires à comprendre et à s’approprier les défis de la performance énergétique et d’une autre part de faire une évaluation pour comprendre comment les copropriétaires prennent des décisions sur des choix de performance énergétique dans une situation de précarité énergétique.Le défi de cette démarche est qu’à travers ce dialogue et évaluation, les copropriétés puissent faire des décisions performantes pour les travaux de rénovation même quand plusieurs de ces copropriétaires sont en situation de PE. / The phenomenon of fuel poverty continues to grow, it is affecting 20.4% of the French population in 2016 against 18.4% in 2013 (ONPE, 2016). This situation requires special attention to the issue of energy performance in buildings energy.Unfortunately, this performance, nowadays is only limited to the question of energy efficiency, it will be necessary to consider the energy saving and the behavior of the actors to achieve true performance. In order to do this, we have mobilized the park of the condominium housing which is a park with complex governance where common decision-making votes for needed tasks is difficult to achieve. To address this complex problem, a deliberative approach establishing a dialogue between co-owners (the managing office, union council, resident co-owners and lessor co-owners) but also with other stakeholders with knowledge on buildings energy renovation (Architect, heat engineer, operation manager…etc.), would enable the co-owners to understand and appropriate the challenges of energy performance and to make an assessment to understand how the co-owners take decisions on energy performance choices in a situation of fuel poverty.The challenge of this approach is that through this dialogue and evaluation, the condominiums housing can make efficient decisions for renovations even when several of its co-owners are in a fuel poverty situation.

Ολιστική ενεργειακή θεώρηση κτιρίωνΣακκά, Αγγελική 06 November 2014 (has links)
Στις χώρες της Ευρωπαϊκής Ένωσης ο κτιριακός τομέας απορροφά περίπου το 40% της συνολικής ενεργειακής κατανάλωσης, γεγονός που καθιστά απαραίτητο το λειτουργικό και φιλικό προς το περιβάλλον σχεδιασμό των κτιρίων, παράλληλα με τον περιορισμό των συνολικών ενεργειακών αναγκών τους για την εξοικονόμηση ενέργειας. Όσον αφορά τα ήδη υπάρχοντα κτίρια, μπορούν να γίνουν διάφορες παρεμβάσεις ώστε να επιτευχθεί η μέγιστη δυνατή εξοικονόμηση ενέργειας. Από την άλλη, η Ε.Ε.,στα πλαίσια της βιώσιμης ανάπτυξης και της προστασίας του περιβάλλοντος, έχει θέσει ως στόχο για το 2020 τα καινούρια κτίρια να είναι μηδενικών εκπομπών διοξειδίου του άνθρακα. Για την υλοποίηση του στόχου αυτού, είναι αναγκαίος ο σχεδιασμός των κτιρίων σύμφωνα με τις αρχές της βιοκλιματικής αρχιτεκτονικής, για την ελαχιστοποίηση των ενεργειακών τους αναγκών αλλά και η εφαρμογή συστημάτων Ανανεώσιμων Πηγών Ενέργειας για την παραγωγή θερμικής και ηλεκτρικής ενέργειας και την ελαχιστοποίηση έτσι των εκπομπών CO2 στην ατμόσφαιρα από τα ορυκτά καύσιμα.
Στην παρούσα διπλωματική εργασία, αναπτύσσονται στρατηγικές που αποσκοπούν στην αρμονική ένταξη των κτιρίων στο φυσικό περιβάλλον, παρουσιάζονται τα θέματα εξοικονόμησης ενέργειας στα κτίρια, διατυπώνονται οι βασικές παράμετροι για την επίτευξη ολιστικής ενεργειακής κάλυψης των κτιρίων και την προετοιμασία του επόμενου βήματος σχετικά με την ενέργεια στα κτίρια για το έτος 2020 και δίνονται νέες τεχνολογικές λύσεις που αναπτύχθηκαν στο εργαστήριο ηλιακής ενέργειας, με σκοπό την βέλτιστη αξιοποίηση της ηλιακής ενέργειας και των άλλων ΑΠΕ στα κτίρια.
Στα πλαίσια της πλήρους κάλυψης των κτιριακών ενεργειακών αναγκών από ΑΠΕ και της προώθησης των κτιρίων σχεδόν μηδενικής κατανάλωσης από συμβατικές ενεργειακές πηγές, μελετάται πειραματικά η συμβολή των φωτοβολταϊκών σε δυσμενή κλίση και προσανατολισμό. Εξετάζεται η συνεισφορά διάχυτων ανακλαστήρων στην ενεργειακή τους απόδοση, η επίδραση του υλικού της θερμομόνωσης και του περιορισμού των θερμικών απωλειών. Τέλος, εξετάζεται η αξιοποίηση κάθε τμήματος του κτιρίου που μπορεί να έχει θετική συμβολή στο ενεργειακό θέμα. Έτσι προτείνονται τρόποι τοποθέτησης φωτοβολταϊκών σε οριζόντιες και επικλινείς στέγες και στις προσόψεις των κτιρίων, με προσθήκη ανακλαστήρα όπου είναι δυνατό, που μπορούν να συνεισφέρουν στην επίτευξη μηδενικού ενεργειακού ισοζυγίου στα κτίρια. / In the countries of the European Union the building sector accounts for about 40% of the total energy consumption, so it is necessary that the buildings should be designed in a functional and environmentally-friendly way, in addition to the minimization of of the total energy needs to achieve energy savings. As for the existing buildings, they should be renovated so that maximum energy savings is achieved. On the other hand, the EU’s target for 2020 is that new buildings must be of zero carbon dioxide emissions. For the implementation of this goal, buildings should be designed according to the principles of bioclimatic architecture to minimize energy needs, but also systems of Renewable Energy Sources should be applied to produce thermal energy and electricity, in order to minimize carbon dioxide emissions from fossil fuels.
In the present thesis, strategies aiming to harmonic integration of buildings in the natural environment are developed, holistic energy saving aspects for buildings are presented, aspects regarding the next step to the target for 2020 are given, and some new designs of building integrated RES, investigated at the Solar Energy Laboratory, are suggested.
Approaching the holistic contribution of the renewable energy sources (RES) to buildings for total cover of their energy demand, and the achievement of nearly zero energy buildings, the contribution of photovoltaics in disadvantageous inclination and azimuth angle is experimentally studied. The contribution of diffuse reflectors to pV’s energy efficiency, the impact of thermal insulation materials and the impact of limitating the thermal losses to PV’s operation, are studied as well. Furthermore, the use of every single part of the building in order to contribute to its energy supply, is considered. Designs for photovoltaic integration on horizontal and inclined roofs and facades are suggested, combined with booster reflector if possible, aiming to achieve zero energy balance of buildings.
