“…To obtain these parameters, the authors have used the detailed Unified LIDER-CALENER software tool (HULC), which is the official building energy certification tool in Spain [90], developed by the authors (for more details view Section 3.4). There are quite a few publications developing its use [65,74,[91][92][93][94][95][96], which allowed certain modifications to be made in order to carry out the validation of the proposed methodology. It is important to highlight that previous simulations using a BEP tool have not been detailed because it will be used as a starting point for the methodology, subsequently calibrating the results using the energy consumption measured in the actual buildings.…”

The reduction of energy consumption in the residential sector presents substantial potential through the implementation of energy efficiency improvement measures. Current trends involve the use of simulation tools which obtain the buildings’ energy performance to support the development of possible solutions to help reduce energy consumption. However, simulation tools demand considerable amounts of data regarding the buildings’ geometry, construction, and frequency of use. Additionally, the measured values tend to be different from the estimated values obtained with the use of energy simulation programs, an issue known as the ‘performance gap’. The proposed methodology provides a solution for both of the aforementioned problems, since the amount of data needed is considerably reduced and the results are calibrated using measured values. This new approach allows to find an optimal retrofitting project by life cycle energy assessment, in terms of cost and energy savings, for individual buildings as well as several blocks of buildings. Furthermore, the potential for implementation of the methodology is proven by obtaining a comprehensive energy rehabilitation plan for a residential building. The developed methodology provides highly accurate estimates of energy savings, directly linked to the buildings’ real energy needs, reducing the difference between the consumption measured and the predictions.

“…The same building, with the same characteristics was analyzed, located in different locations, with 12 climatic zones (A3, A4, B3, B4, C1, C2, C3, C4, D1, D2, D3, E1). These climatic zones are defined in the Spanish scale (Technical Building Code scale [21], Figure 3 in [11]) based on the Winter Climate Severity (WCS, five climate zones in winter, designated by the letters A-E) and the Summer Climate Severity (SCS, four zones for the summer, designated by the numbers 1-4) [22], defining combinations of WCS and SCS indexes different climatic zones.…”

“…The present paper is based on an approach of a previous study [11], focused on the minimization of building's thermal loads through the employment of passive elements, and on a second study [12] focused on the implementation of efficient HVAC systems, as low temperature surface embedded heating and cooling systems. In [12], the HVAC system with different types of energy (Electric Heat Pump-EHP, Gasoil-G, biomass boiler-BB, wood pellets boiler-WPB, natural gas-NG, and woodchips boiler-WCB) is selected.…”

Designing a Zero Energy Building (ZEB) requires an optimal choice of the materials of a building envelope. Different material properties and window areas could be selected to generate a set of possibilities of the design of a building, being the demand defined by its thermal characteristics. The energy demand of a building could be produced with renewable systems such as photovoltaic. Moreover, the HVAC (Heating, Ventilation, and Air Conditioning) systems could be selected considering the system cost. The present methodology focuses on finding a balance between investment and low energy consumption for a building, based on an integrated optimization method. Such methodology applies a Tabu search algorithm and a simplified model to select the passive design. Afterwards, active elements of the design, as photovoltaic systems, are selected. Therefore, the methodology faces the problem of estimating the annual energy demand and the life cycle cost. The goal is the design of a building with a large amount of energy generated by renewable energy, to have a ZEB, and in the worst case, a nearly Zero Energy Building (nZEB). This methodology reduces investment, reduces the energy demand and selects the best construction materials, renewable energy, and air conditioning system. The present paper analyzes a set of case studies considering different climatic zones in Spain. The results conclude that the methodology could help builders in the design stage, to find a new design that allows a ZEB with the optimal life cycle cost.The present paper explores a methodology to design a nZEB building, by choosing design elements in two steps (Figure 1). Firstly, the selection of passive elements, and secondly the selection of active elements with a system of photovoltaic panels to generate the energy required by such building. To achieve a ZEB (Zero Energy Building), the Building Integrated Photovoltaic (BIPV) systems used to generate electricity can play an important role [2]. A comprehensive review of the current state of the art in the area of the BIPV technology is shown in [3]. Moreover, some studies have verified the validity of BIPV systems for the challenge of Zero Energy Buildings [4]. Appl. Sci. 2018, 8, x FOR PEER REVIEW 2 of 14 remaining energy needs and renewable energies. Therefore, a nZEB will not only imply an optimized design and construction, but also the exploitation of energy resources in the most efficient way.

“…The simplified methods [40,54] propose a simple way to calculate the energy demand and an expert system to assist the decision-making, assuming a certain level of error or uncertainty in the results. These methods are commonly applied at larger scales, for instance to study a regional building stock taking into account different climatic conditions using the Degree Days simplified methodology.…”

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.
