“…The optimization results in this study reveal that about 4 MJ/m 2 is saved every year. The results of another optimization study that using building energy simulation and optimization showed that it is possible to cost effectively reduce the space heating and cooling energy requirement of a new house in Sydney where the annual space energy requirement is less than 5 MJ/m 2 [38], but a photovoltaic system is sized to cover the remaining household electricity consumption over the course of a year. Combining optimum single-objective energy efficiency measures, the energy saving in the North-West of Algeriais is about 63.51% reduction of the original annual energy need [39], but it does not use the multi-dimensional optimization software and optimize the variables simultaneous.…”

Abstract:The aim of this paper is to optimize the building shape parameters and envelope parameters influencing the rural building energy consumption in cold winter and hot summer climate. Several typical models are established and optimized by integrated TRNSYS and GenOpt. Single-objective optimization has provided guidance to the multi-dimensional optimization. Building shape and envelope parameters are considered simultaneously by multi-dimensional optimization. Results of the optimization showed significant reduction in terms of EC (energy consumption). When O (building orientation) was SW (south by west) 10 • , LWR (length-width ratio) was 1.1, WWRS (window-wall ratio in south) with the range of 0.6-0.8, ITE (insulation thickness of exterior wall) and ITR (insulation thickness of roof) was 0.05 m and 0.08 m respectively, the building had minimal energy consumption. The results also indicated that the optimal EWT (exterior window type) was plastic single-frame Low-E insulating glazing filled with inert gas, and the optimal shape of building is Re (rectangle). An effective method was provided to optimize the design of the rural building for the purpose of reducing building energy consumption in cold winter and hot summer climate.

Recent progress in computer science and stringent requirements of the design of "greener" buildings put forwards the research and applications of simulation-based optimization methods in the building sector. This paper provides an overview on this subject, aiming at clarifying recent advances and outlining potential challenges and obstacles in building design optimization. Key discussions are focused on handling discontinuous multi-modal building optimization problems, the performance and selection of optimization algorithms, multi-objective optimization, the application of surrogate models, optimization under uncertainty and the propagation of optimization techniques into real-world design challenges. This paper also gives bibliographic information on the issues of simulation programs, optimization tools, efficiency of optimization methods, and trends in optimization studies. The review indicates that future researches should be oriented towards improving the efficiency of search techniques and approximation methods (surrogate models) for largescale building optimization problems; and reducing time and effort for such activities. Further effort is also required to quantify the robustness in optimal solutions so as to improve building performance stability.

“…However, every time the air quality in the building must be taken under consideration -this is possible, in case of the low energy buildings, only through the airflow control and heat recovery. The use of multi-criteria optimization to choose solutions for energy-efficient buildings rate analyses the different permissible solutions can be found [14][15][16][17][38][39][40][41][42][43]. The multi-criteria analysis, proposed in this paper, allows for a classification of the alternative, technical solutions regarding HVAC systems and building itself designing taking under consideration: the economics, energy, environmental parameters in terms of complex energy-related optimum, keeping in the same time all limiting conditions.…”

Abstract. The goal of this paper was to optimize the building envelope and technical equipment in the building through the mitigation of the global cost value, and then to evaluate the influence of the chosen assumptions on the primary energy index. The analyses carried out using global cost method allow for finding the cost optimal solution but only for the some range of primary energy index variability. In order to find the optimal solutions it was proposed to use the multi-criteria optimisation, assuming the following as basic criteria: a global cost value and investment prices increase (economic criteria), a primary energy index (energy-related criterion), an emission of carbon dioxide (environmental criterion). The analysed case study refers to the technical solutions for the residential buildings with the usable energy demand at the level of 40 and 15 kWh/m 2 /a. The presented method might be applied to different types of buildings: those being designed and those being the subject of the thermo-modernisation. The results demonstrate that the proposed model allows for classification of the alternative technical solutions regarding the designing process and the building's technical equipment. The carried out analyses indicate the economic possibility to achieve the low energy building standard and show the need to concentrate the activities related to the installation technology and used energy source.Key words: global cost methodology, low energy buildings, European Union Directive, multi-criteria optimization. focused on the applied mechanical systems in the scope of heating, ventilation, air conditioning (HVAC) and the sources of the energy supplying the building. The goal of these activities is to re-shape the building and its technical equipment in such a way to limit the energy usage. As a result it should lead to the limitation of CO 2 emission. The basic aim of this paper is to present the method of the economic, energy-related and ecological evaluation of the building and its mechanical equipment. The main goal of this paper was to optimize the building's envelope and its technical equipment. The problem of the multi-criteria optimization was solved, including the minimalisation of the global cost, primary energy index, emission of carbon dioxide and the increase of the investment costs in relation to the basic scenario. The options of the possible technological activities aiming for achieving the standards of the low-energy building were compared and then the best solution for the Polish economic conditions was indicated. The analyses referred to the building components, creating the building's envelope as well as to the components of the mechanical systems (HVAC) and the energy sources supplying the building's technical systems. The primary aim was to provide a comparison of the proposed solutions with the basic scenario (BASE).The proposed method was used to indicate the integrated activities (construction technology, mechanical system, energy sources) aiming for the improvement of the technology...
