Integrated multi-criteria evaluation of house’s plan shape based on the EDAS and SWARA methods

With this article we strive to create a theoretical valuation model based on multiple criteria mathematical methods by selecting a basic shape of single-family residential house‘s plan. Most of the researches and analysis discuss the interfaces of architectural shapes of the buildings with sustainability only in the buildings with unique design. Meanwhile, the model comprising a selection of a basic shape of the singlefamily house was not implemented. Our study evaluated the individual parameters associated with selection of the house shape: compactness, safety, material input, variability of premises and spaces. The SWARA (Step-Wise Weight Assessment Ratio Analysis) method is applied in the calculation of the relative importance of the criteria and the EDAS (The Method of Evaluation Based on Distance from Average Solution) method was used to prioritize the alternatives

Architectural solutions to increase the energy efficiency of buildings / Architektūros sprendiniai, didinantys energinį pastatų efektyvumą

While designing the volume of a building, architectural solutions can be employed to achieve greater energy efficiency for the entire lifecycle of the building. However, currently this possibility is not sufficiently utilised. The paper provides a comparative analysis of architectural solutions, presenting the ones that not only allow for a reduction in energy losses through the external envelope of a building considering the local climatic conditions; but also make it possible to increase the use of energy from renewable resources. Santrauka Projektuojant pastatų tūrius yra galimybė, pasitelkus architektūrinius sprendinius, pasiekti didesnį energinį efektyvumą viso jų gyvavimo laikotarpiu, tačiau šiuo metu tuo naudojamasi nepakankamai. Darbe atlikta architektūrinių sprendinių lyginamoji analizė, kurios metu pristatomi sprendimai, leidžiantys sumažinti energijos, prarandamos per pastato išorės atitvaras, kiekį atsižvelgiant į vietos klimato sąlygas, bei padidinti pastato suvartojamos energijos kiekį naudojant atsinaujinančiųjų šaltinių energiją. Reikšminiai žodžiai: A/S santykis, A/V santykis, energinis efektyvumas, geometrinis efektyvumas, pastato gyvavimo ciklas, kompaktiškumas, energijos poreikis, saulės energijos pritekėjimas, tvaruma

Research of low energy house design and construction opportunities in Lithuania / Mažai energijos naudojančio namo projektavimo ir statybos Lietuvoje galimybių tyrimas

Currently, the construction of low energy buildings in Europe is promoted. Existing and newly developed design and construction concepts for such buildings are adapted to their national or regional climatic conditions. The European Parliament has assigned the member countries to get ready for the reduction of the energy consumption in buildings. Therefore, Lithuania, like other EU countries, must be examined for the use of the low energy building design and construction experience, the existing concepts of low energy buildings should be adapted or new concepts of low energy building responding to the region's climate should be created. In this article, the most popular European mid‐region passive house concept and the energetic performance of the house, designed and built according to its requirements is analyzed, the main differences of this concept to the normative requirements of Lithuanian building regulations and proposals to improve provisions for the construction of low energy buildings in Lithuania is provided. Santrauka Šiuo metu Europoje skatinama mažai energijos vartojančių namų statyba. Esamos ir naujai kuriamos tokių namų projektavimo ir statybos koncepcijos dažniausiai pritaikytos konkrečios šalies arba regiono klimato sąlygoms. Europos Parlamentas įpareigojo šalis nares pasirengti mažinti pastatuose suvartojamos energijos kiekį. Todėl Lietuvoje, kaip ir kitose ES šalyse, turi būti išnagrinėta mažai energijos vartojančiių pastatų projektavimo ir statybos patirtis, perimtos jau taikomos arba sukurtos naujos koncepcijos, tinkamos šio regiono klimatui. Straipsnyje išanalizuota populiariausia Vidurio Europos regione pasyviojo pastato koncepcija, pagal jos reikalavimus suprojektuoto ir pastatyto namo energiniai rodikliai, nustatyti pagrindiniai šios koncepcijos ir Lietuvos statybos norminių dokumentų reikalavimu skirtumai ir pateikti pasiūlymai gerinti sąlygas mažai energijos naudojančiu pastatu statybai Lietuvoje.
