“…In the future, experts could provide specific functions as machine-code, which can be detailed and accurate without disclosing confidential details. The machine-code functions of several experts could then be combined to a fast and cost-effective BISE model [122]. In these ways, the modelling of BISE can contribute to reduce the overall costs of BISE and to optimize systems including BISE so that the good BISE technologies can develop to their full economic and ecologic potential.…”

“…Often, one simulation environment is preferred in the current case while another simulation environment may be required in the next case. For this, the concept of multi-environment models was developed [122] in order to make the same code available in many simulation environments. The code is compiled to machine-code and then linked to a wrapper in the targeted simulation environment.…”

PurposeDespite the construction industry's significant impact on high energy use and a growing carbon footprint, technologies like Green BIM help to optimize natural resources, reduce pollution, use sustainable space and work on human comfort and health. But the trend in a holistic approach is minimal. Thus, the paper aimed to systematically investigate Green BIM research and implementation trends using a mixed-method and also show the prospects of holistic Green BIM implementation.Design/methodology/approachFirst, we conducted a Scientometrics analysis on the topic using the Scopus database for the time interval of (2013–present). Secondly, the Qualitative Content Review method asserted the Scientometrics analysis result. Lastly, exploratory research was done on secondary data to compare the AEC industry trend for a comprehensive view.FindingsThe merged findings confirmed the partial implementation of Green BIM and of which 43% of research focused only on energy analysis. Despite the potential of BIM and the interrelationship among green building parameters, the result showed other aspects of green building and sustainable design parameters as green material selection, sustainable site, waste management and water-use efficiency not comprised.Originality/valueThe authors propose a new conceptual framework for integrating green building parameters, BIM tools and green building assessment tools in a life cycle of a project that adds into the sustainability of the Architectural, Engineering and Construction sector. The study would help to provoke researchers, software developers and practitioners for further innovative effort in holistic Green BIM implementation.

“…This Certificate provides information about energy efficiency of buildings and is one of the policies implemented in most Member States that should drive the market towards NZEB.The annual energy performance of a building should be calculated on the basis of several factors (e.g., thermal characteristics, ventilation, internal loads, HVAC installations, and application of renewable energies), and this calculation must be facilitated to architecture and engineering firms [12]. Effective collaboration between design disciplines is one of the reasons for the adoption of Building Information Modelling (BIM) [13].BIM can be used as a platform from which to gather information that can be conveyed to energy efficiency simulation tools by using an appropriate interface. The result of this practice is expected to be the design of more efficient buildings through evaluation of different design options [14].…”

Heating, cooling and domestic hot water (DHW) are responsible for the largest share of energy use in residential buildings in Spain and play an important role in the implementation of nearly zero-energy buildings (NZEB). Building Information Modelling (BIM) is expected to promote more efficient buildings through evaluation of different design options. BIM can be used as a platform from which to gather information that can be conveyed to energy efficiency simulation tools. The objective of this paper was to implement the model of a reversible air-to-water heat pump in EnergyPlus 8.9. This model was employed to analyze the performance of an aerothermal heat pump system (B) in a residential building under different Spanish climates compared to a conventional Heating, Ventilating and Air Conditioning (HVAC) system (A). Significant primary energy savings were achieved with system B compared to system A. These energy savings were higher in climates with a significant heating demand such as Madrid (27.4%) and Burgos (33.6%), and in cities with a mild climate such as Barcelona (37%). The residential building studied in this work was classified as Class A according to the CO 2 emissions scale when using the aerothermal heat pump system, and as Class B when using the conventional HVAC system.The EU's recommendation on guidelines for the promotion of NZEB [5]provides benchmark ranges of primary energy use (kWh/m 2 per year) for the different EU climatic zones [6]. Characterization of climate zones can be used to guide the design of NZEB by suggesting the suitability of certain technologies to certain climatic zones [7].In Spain, 93% of the installed aerothermal heat pumps that meet the requirements established by Directive 2009/28/EC are located in climatic zones characterized by mild outdoor dry-bulb temperatures. They are almost exclusively of the air-to-air type, with a very low number of units driven by other renewable energy sources (geothermal or hydrothermal). By sectors, most heat pumps are installed in households (86%), which is also the predominant sector in terms of installed capacity (57%) [8].Current technology allows the use of aerothermal heat pumps in more severe climatic conditions. Houlihan et al. [9] studied the case of a detached single-family house located in Oslo. The implemented residential NZEB concept was the so-called all-electric solution where essentially a well-insulated envelope was heated using an air-to-water heat pump and where photovoltaic panels (PV) production was used to achieve the CO 2 balance.Authors concluded that the house could be labeled as a zero-energy building.However, geothermal heat pumps are more suitable for the climatic conditions of Northern Europe than aerothermal heat pumps. Paiho et al. [10] analyzed life-cycle costs (LCCs) of different heat pump-based NZEB concepts for a Finnish new detached house and a new apartment building. They found that for both building types, the LCCs were the smallest with the ground source heat pumps (GSHPs) followed by the air-to-water heat...
