“…Energy simulation has become a powerful tool supporting the design of new buildings and in proposing Energy Conservation Measures (ECM) in existing buildings. It is used in the application of the predictive model control (MPC) techniques [ 4 , 5 , 6 , 7 , 8 , 9 ], in actions for the operational optimization of Heating Ventilation Air Conditioning (HVAC) [ 10 , 11 ], in economic strategies [ 12 , 13 , 14 , 15 ], and in the optimization of cost-effective building refurbishment [ 16 , 17 ]. In terms of building energy models (BEMs), Hence and Lamberts [ 18 ] differentiated between the following types depending on the physical relevance of the parameters: White box models are based on a physical models with exclusively physically meaningful parameters.…”

The digital world is spreading to all sectors of the economy, and Industry 4.0, with the digital twin, is a reality in the building sector. Energy reduction and decarbonization in buildings are urgently required. Models are the base for prediction and preparedness for uncertainty. Building energy models have been a growing field for a long time. This paper proposes a novel calibration methodology for a building energy model based on two pillars: simplicity, because there is an important reduction in the number of parameters (four) to be adjusted, and cost-effectiveness, because the methodology minimizes the number of sensors provided to perform the process by 47.5%. The new methodology was validated empirically and comparatively based on a previous work carried out in Annex 58 of the International Energy Agency (IEA). The use of a tested and structured experiment adds value to the results obtained.

“…In terms of scale, we observe that a majority of applications of the methodology have been at the building or component scale, especially to compare different constructive solutions and construction materials or to optimize the insulation thicknesses of the building envelope [8,12,32,33,[37][38][39][40][41][42]. When at the building scale, studies typically consider only one specific typology for a given period of time or year (e.g.…”

“…15 years for a boiler versus 50 years for thermal insulating elements. Likewise, the order of priority in the implementation of different renewal strategies (passive or active) is important to achieve a high value of long-term savings in terms of energy, GHG emissions, and cost [10][11][12]24,41]. First, it is necessary to act on the building envelope to reduce the energy demand, and then install active systems adapted to the new demand.…”

As tomorrow's cities are already largely built, many strategies stress the importance of urban renewal processes to address current energy issues. This paper focuses on the Spanish residential building stock built until 2001, which has a low level of energy performance.Considering the current economic crisis, the future lies in renovating the built environment, which holds a significant energy-saving potential. This potential is here quantified by applying the cost-optimal methodology, initially proposed by the Energy Performance of Buildings Directive, and which calculates costoptimal levels of minimum energy performance requirements at the building and component scale.The originality of our study lies in the application of this methodology at the territorial scale, comparing different retrofitting scenarios by scaling-up building-scale results through an archetypal approach. We also describe an Excel-based tool allowing two types of studies: (i) at the building scale, for one archetype in a particular climatic zone; (ii) at the territorial scale, to have an overview of all building archetypes and climatic zones simultaneously. Results include economic aspects, energy consumption and savings and associated emissions.The outcome can help construction-sector firms adapt their business plan, while also providing stakeholders with decision-support to promote a sustainable renewal of the building stock.

“…In addition, there are also several scientific studies developed in Spain [13][14][15][16]. They cover different regions, the northern [13,15] and the southern [14], and all of them are focused on residential sector.…”

“…However, not all the studies implement the cost-optimal method but, they proposed other variables of decision: [15] included the payback period as additional parameter for the economical evaluation; [14] used the construction costs and the CO 2 emissions to analysed the impact of different building legislations; and [13,16] implemented the Life Cycle Cost and the Life Cycle Impact Assessment.…”
