AAC WORLDWIDE %u2022 2.2025 PROJECTS 97Birds eye view on the Ca la Siesta, a single-family Passivhaus in J%u00e1vea by Bataille Living.New Ytong enclosure system for passive housesThe Ytong - Ursa External Wall Ventilated Fa%u00e7ade System is an enclosure system specially designed for multi-family houses that guarantees a continuous envelope with high insulation values. The cladding can be adapted to the needs of the designer and different solutions to ensure the airtightness, both on the inside face of the walls and those susceptible to movement, as well as in the joints with the exterior carpentry and installation passages.In order to comply with the Passivhaus standard, it is crucial to guarantee the correct performance in critical areas. %u201cThe great contribution of this cladding system is that in addition to working in terms of thermal insulation and airtightness, it addresses one of the fundamental goals of low-energy houses, the thorough elimination of thermal bridges, without detriment to the final aesthetics of the fa%u00e7ade%u201d says Cristina Tom%u00e1s, technical manager of Xella Spain for the Levante area and main developer of the cladding system for ventilated fa%u00e7ades.As Pablo Rodr%u00edguez, Head of national technical department of Xella Spain points out, %u201cto achieve the certification, every project must follow strict guidelines, from design and planning to final validation by the Passive House Institute. The project must be developed by professionals, familiar with the principles, using tools such as the Passive House Planning Package to model and forecast the building%u2019s energy performance. During construction, it is essential to maintain high quality standards to ensure that the criteria for airtightness, insulation and other passive house principles are met. Tests such as the Blower Door Test are carried out to verify that the building complies with airtightness requirements, and finally an accredited certifier evaluates all documentation and test results. If the building meets all criteria, certification is awarded.Mediterranean comfort in Ca la SiestaCa la Siesta, a single-family house in J%u00e1vea by Bataille Living, showcases the adaptability of low-energy house design to diverse climates and styles. With a combination of Ytong structural and partition walls and other products, Ca la Siesta achieved Passivhaus certification and was presented at the 15th Spanish Passivhaus Conference organized by the Passivhaus Building Platform. According to Enrique Salavert, the project%u2019s technical architect, %u201cthe aim was to build a Mediterranean-style house with special emphasis on the sustainability of the house, which is why materials such as Ytong, natural cork insulation in floors and wood fiber insulation were chosen%u201d. The house has a low water footprint thanks to the collection of Mediterranean-style house with special emphasis on the sustainability of the house %u2013 a reason why autoclaved aerated concrete was chosen.
