“…Some studies utilize a monthly balance [15][16][17], and in a few cases the full life cycle of the building [8]. The pros and cons of possible periods of balance are summarized in [5]. The significant use of annual balance can be attributed to the fact that some parameters, such as building inhabitants and weather data, may vary every year, which led to variations in the final energy balance.…”

The feasibility of Plus Energy Building for a sample relevant case is investigated. After a literature review aimed to identify key aspects of this type of buildings, a preliminary evaluation of the thermal performance of a building constructed using conventional material is presented together with a parametric analysis of the impact of typical influential parameters. Solar domestic hot water (SDHW) and photovoltaic systems (PV) are considered in the study. Numerical simulations indicate that for the examined sample case (Beirut in Lebanon) the total annual energy need of conventional building is 87.1 kWh/y.m 2 . About 49% of energy savings can be achieved by improving the building envelope and installing energy efficient technologies. Moreover, about 90% of energy savings in domestic hot water production can be achieved by installing a SDHW system composed of two solar collectors connected in series. Finally, the addition of a grid connected PV array system can significantly mitigate the energy needs of the building leading to an annual excess of energy.

“…Dostarczając nadwyżkę czystej energii do sieci, budynki takie przyczyniają się do zmniejszenia ogólnej emisji gazów cieplarnianych. Nie zawsze przekształcenie budynku w budynek zeroenergetyczny jest finansowo opłacalne, ale energia pochodząca z budynków plus energetycznych może nieco równoważyć tę sytuację (Hawila i in., 2022).…”

Streszczenie: Sektor mieszkaniowy jest jednym z najbardziej energochłonnych sektorów, a więc w dużym stopniu przyczynia się do pogłębiania kryzysu klimatycznego. Osiedla zrównoważone mogą być zatem ważnym narzędziem w ochronie środowiska. Celem artykułu jest omówienie i ocena zrównoważonego budownictwa na wybranych przykładach osiedli zrównoważonych. W artykule zastosowano metodę opisową, krytyczną analizę literatury, proste metody statystyczne oraz analizę studiów przypadku. Przedmiotem badań są osiedla zrównoważone -osiedle BedZET w Wielkiej Brytanii oraz osiedle Hammarby Sjöstad w Szwecji. BedZET jest dobrym przykładem dla kwestii społecznych, lecz nie udało się w jego użytkowaniu osiągnąć celu zeroemisyjności. Z kolei szwedzkie osiedle, mimo ogromnych oszczędności energii, boryka się z problemami społecznymi. Połączenie najlepszych rozwiązań z obu tych osiedli mogłoby przyczynić się do stworzenia osiedla niemalże idealnego, co ze wsparciem władz rządowych i samorządowych jest możliwe do osiągnięcia w Polsce.

“…Plus Energy Buildings (PEBs) has received increasing attention in recent years. Their potential has been discussed in studies, while not yet demonstrated [3][4][5]. Furthermore, due to novelty of such building systems, their environmental relevance of this concept has been often questioned [6].…”

“…Lastly, as a further step, LCA in CULTURAL-E provides the analysis on the whole building level and, more specifically, on culturalclimate designed demo cases. This allows the identification of hotspots for the environmental assessment and the derivation of benchmarks for PEHs to be used by stakeholders as reference values [4].…”

The situation reported from the Global Status Report 2021 and the now war-related risks urge the application of measures for decreasing emissions and energy consumption, aiming carbon neutrality by 2050. Smart solutions for decreasing energy consumption are researched and implemented in the context of energy efficient buildings and Plus Energy Houses (PEHs). As PEHs gained an increasing consideration for the challenge of energy consumption reduction, their design produced a multitude of solutions. In such a multitude, an optimum is defined by accounting and comparing the performance offered by provided technologies and the actual technical requirements. The latter can be affected by the geographical/climate context as well as the user behaviour and socio-cultural aspects. This objective has been addressed in the CULTURAL-E research framework. Furthermore, in compliance with the current climate targets, this framework attributes a central role to the environmental performance of systems designed for PEHs. In this work, environmental impacts’ investigations of solution sets for PEHs are provided according to the Life Cycle Assessment (LCA) methodology. The developed bottom-up approach provides lifecycle information hierarchically on three levels (component, solution sets and PEH), while information of operation energy is derived through building energy simulations and average user-related energy usage. The selected 8 case studies are drawn from the CULTURAL-E research and include solution sets tailored for climate and socio-cultural clusters. Innovative technological components as well as conventional technologies are included. Based on such analyses, an environmental (CO2) payback periods have been estimated, i.e., the time required to recoup the total expended embodied CO2 through building operation carbon positivity. Results identified potentials for climate mitigation and different performance levels of the implemented technologies and photovoltaics systems, especially for countries in which a faster shift to renewable energy sources is needed for meeting the 2050’s environmental targets.
