“…Nearly Zero-Energy Buildings (NZEBs) are defined as low-energy buildings with superior building performances than conventional buildings, and renewable energy resources are often applied to meet the energy requirements of NZEBs [11,12]. As the ultimate target of NZEBs is to achievable zero energy consumption, the designs and constructions of NZEBs require high energy efficiency levels of the NZEB and passive strategies for improving the energy efficiency levels [13]. As part of the passive strategies for improving energy efficiency levels of NZEBs, the building envelopes have notable impact on both the built environment and methods of building designs and constructions [14].…”

The Prefabricated Straw Bale Construction (PSBC) has been proven as one of the most efficient construction methods to achieve low-energy buildings with low environmental impacts. This research presents analysis of the rationale for using straw bale constructions in northern China and a discussion of feasible constructions of PSBC to meet the local building codes following evaluations of potential energy performance of domestic buildings with PSBC in severe cold regions and cold regions in China. The results show that the buildings with PSBC reduce both heating and cooling energy uses, as well as heating intensities across the severe cold and cold regions, compared to the domestic buildings with conventional constructions. The findings of this research will contribute to reducing energy consumption in building industries in China.

“…al 2013] and recently the last EPBD recast-approved in June 2018-introduced the requirement for the Member States to steadily lead the transformation of the building stock in the EU to reach nearly zero-energy performance levels by 2050 with the preparation of long-term renovation strategies (LTRS) supported by financial measures [EU 2018/844]. To reach this target, energy conservation strategies play a crucial role [Brambilla et. al, 2018]; coupling new envelope techniques [Salvalai et.…”

At the present, the ventilated façade is one of the most widely used and most innovative systems characterized by different energy saving features, but due to its complexity, the real performances are difficult to predict by numerical analysis. This work shows the results of the monitoring campaign conducted on two Cross Laminated Timber (CLT) test boxes equipped with different thermal coat technologies to realize the performances comparisons. In particular, the investigation focus on the evaluation of surface temperatures of the different wall layers and the indoor air temperature for: i) a micro ventilated façade and ii) two different ETICS solutions. The monitoring campaign has been conducted during the summer season on walls with equivalent thermal transmittance (U-value) and different thermal capacity. In detail, the experimental work has been performed to estimate the Isotec® wall micro ventilated façade performance in comparison with two traditional ETICS technology: the first one realized with EPS and the second one with high density rock wool insulation. The results show that due to the shading effect provided by the external layer, the temperature within the cavity of the ventilate façade is reduced by 8–10 °C, reducing the cooling loads through the wall by 30–40% with respect to ETICS with EPS. The shading and the ventilation effects balance the presence of thermal insulation with less heat capacity; consequently, it validates the good quality of Isotec® as wall technology with performances comparable to ETICS solution with high density rock wool insulation.

“…From the results, a reasonable thickness of insulation material is available only with Aeropan, in comparison to Expanded Polystyrene, Extruded Polystyrene and Mineral Wool, demonstrating its suitability in the accomplishment of passive house requirements, with a significant reduction of the required space. In the paper [28], the renovation and re-use of the Atika building, a demonstrative energy-efficient building, is presented as a case study of an environmental efficient methodology for energy retrofitting. The case relies on the methodology developed by Active House.…”

This paper compares the sustainability aspects of three family houses according to the Slovak building environmental assessment system (BEAS). Various categories of family houses were evaluated, including site selection, project planning, building construction, indoor environment, energy performance, and water and waste management. Based on the results, Family Houses 3 and 2 are certified as BEAS SILVER, with scores of 2.46 and 2.01, respectively. Family House 1 is certified as BEAS BRONZE, with an overall score of 1.44. The results show, not only the importance of the site in terms of availability, connectivity to the network and the potential to use renewable energy sources, but also the importance of the design and construction of the building, including the application of environmentally friendly building materials, ensuring the quality of the indoor environment and the energy efficiency of the building. The aims of this study were to highlight the current trend in the design and construction of low-rise residential family houses in Slovakia and to identify gaps in the design and construction of key sustainability aspects through the existing building environmental assessment system. In the future, many low-rise residential family houses will be assessed to modify and validate BEAS.
