Apartment Buildings

The majority of Lithuanian multi-apartment residential buildings were built before 1993. Moreover, projects of housing renovation and maintenance have not been carried out before 1996. Lack of proper maintenance led to a significant deterioration of multi-apartment buildings. Most of these buildings are neither economic, nor environmentally-friendly and consume a significant amount of heat energy. Six major construction requirements should be satisfied when designing or refurbishing a building. Sustainable renovation of multi-apartment buildings and their environment is a universally recognized problem. It is crucial to evaluate both the buildings and their surrounding environment. A proper building renovation project can be created and selected only by performing multi-criteria assessment. Therefore, this paper presents a sustainable multi-apartment building assessment method, which is applied specifically for Lithuania and could help renovate multi-apartment buildings in residential areas of Lithuanian cities more effectively. After performing the analysis of modern building sustainability assessment methods, the BREEAM method was chosen as the basis for the proposed method, specifically adapted to Lithuania. It is one of the oldest and most widely used methods used for assessment of the environmental effect of buildings. This method allows evaluating the building's utility from the ecological perspective in the following areas: management, health and wellbeing, energy, transport, water, materials, waste, land use and ecology, pollution and innovation. However, BREEAM and other similar methods cannot be used to assess the financial aspects of a building, which should be included in the analysis at all assessment stages along with the aspects of environment protection. When creating a renovation project, an important criterion is the payoff of it; therefore, the absence of financial assessment diminishes the effectiveness of the BREEAM assessment method. To address this problem, the proposed method is complemented with an additional set of economic assessment criteria. Furthermore, the BREEAM method is modified, taking into account the conditions in Lithuania and determining new significances of the criteria sets. By applying this method, specifically adapted to Lithuania, the assessment of a renovation project of a standard 47-year-old multi-apartment building was made. The assessment score was 71.77%, therefore, the renovated building satisfied the sustainability requirements and was given an “Excellent” sustainability status. The application of the assessment method adapted to Lithuania could help renovate multi-apartment buildings in residential areas of Lithuanian cities more effectively. This, in turn, could result in a higher quality of life, since the consumption of natural resources and CO2 emission would decrease. Renewable energy sources would become more widespread and, therefore, the climatic changes would occur less often. Santrauka Didžioji dalis Lietuvos daugiabučių gyvenamųjų namų pastatyti iki 1993 m. Jie dėl nepakankamos priežiūros dabartiniu metu yra smarkiai nusidėvėję. Dauguma jų neekonomiški, neekologiški, suvartoja daug šilumos energijos, tokius daugiabučius reikia modernizuoti. Projektuojant ar atnaujinant pastatą turi būti laikomasi šešių esminių statinio reikalavimų. Todėl norint nustatyti pastatų atnaujinimo efektyvumą, reikia atlikti išsamų ir visapusišką vertinimą. Šiame straipsnyje siūlomas Lietuvos daugiabučių atnaujinimo darnumo vertinimo metodas, grindžiamas darnių pastatų vertinimo metodu BREEAM. Šis metodas padėtų efektyviau vykdyti daugiabučių namų miestų gyvenamuosiuose rajonuose atnaujinimą, pirmiausia pagerinant pačių pastatų būklę ir jų aplinką, taip pat gyvenimo kokybę, sumažinant gamtinių išteklių naudojimo mastą, CO2 emisiją ir socialinę atskirtį, padidinant atsinaujinančiųjų energijos šaltinių vartojimą bei stabdant klimato kaitą.

In the recent years, the design for high-rise residential buildings in Shanghai has been changing in floor plan. It is the transformation in the shape of the house from residential tower-shaped buildings into combined apartment buildings; the transformation in constitution of floor plan, the number of apartment in each floor; the transformation in area and function of each apartment and even in living habits. Studies of the transformation in shape mentioned above were carried out by the morphology methodology. Combined apartment buildings in Shanghai combined together leads to high economic benefit, and the number of floors is up to 34 floors. Auxiliary area which is shared equally to each apartment, accounts for an approximately large portion of a typical floor plan. Each apartment in Shanghai must be added 12-18% of external auxiliary area. The cause and effect of the transformation in the design for high-rise apartment buildings are valuable experiences for other developing metropolitans in China, so as other countries in region.

Design Stage

Buildings are responsible for several negative impacts on the environment, most of them related to nonrenewable energy consumption, increasing the concern regarding buildings energy efficiency. In this context, computer software has been used to estimate the energy needs of the built environment, and the Building Information Modelling (BIM) methodology can be used to simplify this process. This study aims to validate a BIM-based framework to streamline the energy analysis of Portuguese buildings, based on the method of the national regulation for the thermal performance of residential buildings. Currently, designers need to spend considerable time assessing all the building characteristics and performing the mandatory calculations for energy performance analysis. It is also intended to link the results of the energy simulation with a Building Sustainability Assessment method—SBToolPT-H. The purpose is to demonstrate how it is possible to benefit from this approach to simultaneously improve building sustainability during the design stage. To do so, different case studies were modelled in Autodesk Revit and exported to a BIM energy tool to perform energy simulation analysis. The results were validated against the official assessment method of the Portuguese thermal regulation and were successfully used to assess the SBToolPT-H energy efficiency category. The research outcomes provide design teams with a reliable BIM-based framework to improve building energy performance and to develop thermal projects while enhancing building sustainability. It also increases the knowledge about the integration of sustainability assessment in the BIM environment, providing new insights for complete integration.

The Impact

A simple method for the assessment of sustainability of a residential building is proposed. The method consists of two steps. First, areas that influence sustainability level of the building (e.g. building architecture, design, in‐built materials) are identified. For each area, several elements and corresponding indicators are determined. Depending on their nature, the indicators are expressed either in quantitative or qualitative terms. The impact areas and their corresponding elements influence all three aspects of sustainability. In the second step, the indicators are aggregated according to their influence on individual sustainability aspects. Special attention is placed to the determination of weights assigned to the indicators in order to make the assessment method relevant in the local context. Initially, the consensus‐based method within the research team was used as a technique for aggregated indicators’ weighting. Later, the open discourses among the developers and stakeholders, as well as surveys, were employed to determine the aggregated indicators’ weights. The proposed method is applied to a selected sample building, and the analysis of the results is carried out. The results obtained show that the completeness and reliability of the input data is crucial for the reliability of the proposed assessment method. Subjectivity in evaluators’ judgments required to score some indicators needs to be reduced by introducing adequate training of the assessors. The feedback from the potential users shows that the method has a potential for wider future implementation in practice. Santrauka Straipsnyje siūlomas paprastas gyvenamųjų namų darnos vertinimo metodas. Šiuo metodu skaičiuojama dviem etapais. Pirmuoju etapu nustatomi kriterijai, darantys įtaką pastato darnos lygiui (pavyzdžiui, pastato architektūra, konstrukcija, medžiagos). Nustatomi keli kiekvieną kriterijų apibūdinantys rodikliai. Priklausomai nuo pobūdžio jie gali būti kiekybiniai arba kokybiniai ir gali apibūdinti visus tris darnos aspektus. Antruoju etapu rodikliai sugrupuojami pagal jų įtaką atskiriems darnos aspektams. Ypatingas dėmesys skiriamas rodiklių reikšmingumų nustatymui. Tai vertinimo metodą daro tinkamą konkrečioms sąlygoms. Rodiklių reikšmingumai nustatomi grupės ekspertų nuomonių sutarimo metodu. Vėliau reikšmingumai tikslinami diskusijoje tarp susinteresuotų grupių narių. Pasiūlytas metodas pritaikytas pasirinktam tipiniam pastatui, atlikta gautų rezultatų analizė. Rezultatai atskleidė, jog pradinių duomenų išsamumas ir tikrumas daro lemiamą įtaką pasiūlyto vertinimo metodo patikimumui. Tinkamai apmokant vertintojus galima sumažinti kai kurių rodiklių vertinimo subjektyvumą. Potencialių vartotojų reakcija rodo, kad ateityje šis metodas gali būti plačiai taikomas.

This research aimed to investigate the present situation regarding residential neighbourhood in hot-dry climates. The area of study comprised four urban classes in Greater Khartoum. The problems of residential buildings were examined, aiming to find a sustainable assessment method for evaluating residential areas and their services The methodology of the research began with a literature review for identifying passive and sustainable solutions suitable to hot-dry climates. This method employed eight main categories: sustainable sites, indoor environmental quality, outdoor thermal control, building forms, materials and resources, water supply, power supply systems, and environmental plan processes and CO2 emisions. In addition, a points scale was used, based on ratings of ‘Excellent’, ‘V. Good’, ‘Good’, and ‘Pass’, with a total of 125 points to determine the evaluation result for a building. The study evaluated an urban sample in the Al Taief neighbourhood. A survey was initiated by identifying the standards for selecting the case study, the survey studied 48 cases in the residential areas, analysed the collected data, and then summarised it into tables and figures. The results presented indicated that 19% were Good, 25% were Pass, and 56% were considered ‘weak’. The conclusions and recommendations regarding urban housing services can be applied to sustainable ecological neighbourhoods.

The paper shows that a comprehensive intersectoral approach is needed to address the issues of systematic management of energy saving in agriculture and to justify rational measures of economic support for the state-initiated introduction of energy-saving technologies, machines, and projects. Such requirements are met by the energy-economic (bioenergy) assessment method. The energy-economic assessment consists in comparing the costs of cultivating plants or servicing animals in single units of measurement with the production results and is mainly of national strategic importance. On the basis of such assessment, economic guidelines and incentives for the introduction of new energy-effi cient technologies, machines and projects, including the use of renewable energy sources, can be developed. The author presents an approach to improving the methodology of energy-economic assessment of agricultural technologies and projects when using renewable energy sources in technological processes. It is proved that in order to ensure the reliability of the energy-economic assessment associated with permanent technological and organizational changes and the digitalization of technology and economy, it is necessary to continue research to improve the assessment methodology, as well as clarify and regularly update energy equivalents.
