“…More specifically, the authors have used the energy performance index of windows in order to identify their cooling energy performance in Mediterranean regions [9,10]. The work includes both residential [9] and office buildings [10], due to the fact that the internal heat gains and the ventilation modes vary significantly between these buildings types, leading to different window performance patterns as well as design concepts [11].…”

Abstract-In near zero energy buildings (NZEB) built in Baltic countries, heat production systems meet the challenge of large share domestic hot water demand and high required heating capacity. Due to passive solar design, cooling demand in residential buildings also needs an assessment and solution. Heat pump systems are a widespread solution to reduce energy use. A combination of heat pump and solar thermal collectors helps to meet standard requirements and increases the share of renewable energy use in total energy balance of country.The presented paper describes a simulation study of solar assisted heat pump systems carried out in TRNSYS. The purpose of this simulation was to investigate how the performance of a solar assisted heat pump combination varies in near zero energy building. Results of three systems were compared to autonomous (independent) systems simulated performance. Different solar assisted heat pump design solutions with serial and parallel solar thermal collector connections to the heat pump loop were modelled and a passive cooling possibility was assessed. Simulations were performed for three Baltic countries: Lithuania, Latvia and Estonia.

“…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.…”

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.
