Zola Windows now offers the American Heritage SDH, a high-performance, all-wood simulated double hung window for landmarked and other historic buildings. This replica-quality window has been engineered to include a lower Zola Tilt & Turn and a Fixed upper that provide outstanding performance, all while maintaining the style and proportions of a traditional double hung window. Today’s renovations of historic buildings are becoming increasingly focused on achieving maximum energy efficiency for reduced monthly utilities costs and a minimized carbon footprint. In energy efficient retrofits, air tightness and R-values of the windows become crucial, which cannot be achieved with sliding windows. Double hung windows, which are very common in older buildings, present a major challenge to architects and builders aiming to significantly improve energy efficiency of historic buildings while preserving their architectural heritage. The Zola American Heritage SDH features R-11 glass and triple air seals. At the same time, it maintains the original architectural aesthetic due to its historic style, proportions, and also the clever use of offset glass planes that create the shadow line that is characteristic of a historic double hung window. With its triple seals and top of the line low-iron European glass, the American Heritage SDH offers superior acoustic performance. For increased sound protection, Zola also offers the window with custom asymmetrical glazing, which provides up to 51 decibels (dB) of sound deadening performance. The American Heritage SDH also boasts outstanding visible light transmittance of VT=0.71, allowing for maximum daylighting. Zola’s all-wood American Heritage SDH is available in a variety of furniture-grade species, including FSC-certified pine, oak, and meranti. Photo Credit: Amiaga Architectural Photography

Se utilizan por toda la vivienda materiales como la piedra natural extraída localmente, los enfoscados tradicionales de cal, la madera recuperada de la propia vivienda, y otros materiales y técnicas tradicionales que se emplean sin embargo, con una comprensión contemporánea de los mismos. Desde el punto de vista espacial, la escalera interior que comunica cada uno de los niveles es, sin lugar a dudas, el elemento más importante de la casa. Recorrerla supone una auténtica experiencia sensorial, pues se trata de un espacio enteramente construido en piedra natural -casi simulando una gruta donde los reflejos, las luces y las sombras, acompañan a lo largo de su singular recorrido. En fachada, el dueño de la casa, artista de profesión, le dará nombre a esta obra mediante toda una serie de gigantes que, grabados en piedra y vidrio, permiten relacionar la obra con aquellas viviendas del pasado cuya simbología no era sino la cristalización del particular carácter de sus propietarios.

McKeesport Downtown Housing, formerly a YMCA, is an 84-unit SRO for people at risk of homelessness. The old brick and terracotta building was important historically for McKeesport. The decision to design the project to Passive House criteria actually went a long way to making the pro-forma work. This project was the first large scale retrofit to be designed to meet Passive House Standards in the US. Another major concern of the project team was to maintain the historic charm of the building. Space was at a premium and a reorganization of space allowed for making larger resident rooms. Through a community process with various stakeholders, amenities were identified and added to the project, including a community room, a bike storage area, exterior smoking balconies, single-user rest rooms, a bed bug room for non-toxic treatment of bed bugs, and communal kitchens to provide healthy options for food. The renovation includes new additional lighting, air-conditioning, make-up air and ventilation systems, an elevator, and cooking facilities. A cold-weather shelter, 60-day emergency housing, bridge housing, and section 8 apartment rentals make up the housing programs within the shelter. Thoughtful Balance designed the interiors, and selected the furniture for durability and resistance to bed bugs. The project team worked closely with Zola Windows to specify a unique uPVC window that not only offers passive house performance levels at an affordable cost, but also harmonizes with the building’s historic aesthetic. Zola’s American Heritage SDH (simulated double hung) from the popular, budget-friendly Thermo uPVC line was specified for the project. The windows implemented in this project feature a lower tilt & turn window and a fixed upper for maximum airtightness and thermal performance. The implementation of these windows helped the project team achieve a very significant energy consumption reduction of at least 75%. Photographer: Alexander Denmarsh
