“…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...

“…The previous studies on decision-making process for HVAC&R systems selection which are available through the open literature (Hitchcock 1991;Shams, Nelson, and Maxwell 1994a;Avgelis and Papadopoulos 2009;Wang, Jing, and Zhang 2009a;Shahrestani, Yao, and Cook 2012) can be categorised into four main groups, which are described in the following sub-sections:…”

“…For the HVAC&R systems selection, 'ELimination Et Choix Traduisant la REalité (ELECTRE) III' was adopted as a formal decision-making method (Roy 1996). The final decision was made through consideration of three different economic scenarios/assumptions about the annual changes in the price of energy commodities including crude oil, natural gas and electricity (Avgelis and Papadopoulos 2009). Despite the fact that this study addressed high-demand issues, five main areas of improving HVAC&R systems selection were identified.…”

The approach described by Avgelis and Papadopoulos (2009) is not user-friendly, is too complex, time-consuming and therefore expensive to be adopted in practice.

Buildings account for more than 40% of total energy consumption in most countries and more than 55% of this energy is used by heating, ventilation, air-conditioning and refrigeration (HVAC&R) systems. This significant energy demand, together with the global need to impose energyefficiency measures, underlines the importance of selecting the most appropriate HVAC&R system in the early stages of a design process. However, this state-of-the-art study reveals that there is no review paper available in the open literature to critically analyse the existing methods for HVAC&R systems selection. Therefore, the aim of this paper is to critically review the body of knowledge on the adopted approach for HVAC&R systems selection. Based on the comprehensive literature review, the needs and gaps in this field are identified. It is revealed that the integration of probabilistic climate changes into the decision-making processes is one of the main areas that should be addressed in future studies. In addition, reliability and Life Cycle Cost of the systems, health and well-being, occupants' satisfaction and indoor air quality are of paramount factors that should be taken into account in the decisionmaking process for HVAC&R systems selection.

In this study, to enhance the performance of a central heating system, the following tasks were performed on the system via Radio Frequency modems: collection of data, evaluation of the system, real time monitoring, remote control, and management processes. A central heating system testing apparatus and related software and hardware were developed. Both short‐time and long‐time experiments were conducted. In the experiments, Case 1, in which the system operated under ambient conditions for an hour without remote control, was compared with Case 2, in which the space temperature was kept constant at 21°C. The experimental results indicated that Case 2, in which remote control‐based energy management was conducted, resulted in 20 L of fuel savings compared to Case 1, and a 57–60% thermal efficiency was measured. As a result, a central heating system using remote control‐based energy management is more efficient, economical, and less harmful to the environment. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 600–609, 2017
