Located in the Fort Greene Historic District, this Italianate brownstone is one of a group of ten that were built by Brooklyn builder William Bedell around 1868. This is the only unified blockfront in this historic district, according the the NYC Landmarks Preservation Commission.

When it comes to energy conservation and sustainable building, the Passive House design standard sets the bar high. At WindowFix, we understand the significance of this standard and have a team of experts trained in implementing Passive House principles when retrofitting a property. Our goal is to provide valuable guidance to customers seeking energy-saving renovations, ensuring their projects meet the highest standards of efficiency.

Regarding this retrofit project, we had the opportunity to furnish and install over 50 Zola wood windows and doors that were Passive House Certified. The historical brownstone was retrofitted to meet Passive House standards, presenting numerous obstacles along the way. One of the critical aspects was the meticulous installation detail for the openings, as well as the coordination of air tightness throughout the structure.

Achieving Passive House certification requires a collaborative effort among various teams involved in the retrofitting project. Our experience and expertise in this building standard played a pivotal role in advancing the project towards certification through the esteemed Passive House Academy (PHA). With our guidance and dedication, the brownstone underwent a remarkable retrofitting transformation, combining historical preservation with cutting-edge sustainability.

The installation of Zola wood windows and doors played a crucial role in achieving the desired energy efficiency for the brownstone. Zola is renowned for its Passive House Certified products, which excel in thermal performance and air tightness. By integrating these high-quality windows and doors, we ensured optimal insulation and reduced energy consumption, all while preserving the historical charm of the property.

Retrofitting a historical brownstone to meet Passive House standards comes with its fair share of challenges. Our team of experts meticulously addressed these obstacles, focusing on the installation detail and air tightness coordination. By implementing the Passive House principles, we overcame these challenges and created an energy-efficient living space that meets the rigorous standards of sustainability.

At WindowFix, we take pride in our ability to offer tailored solutions for every project. In addition to the installation process, we also recognized the importance of customizing the window and door screens to enhance functionality and aesthetics. By designing and fabricating custom screens specifically for these wood windows and doors, we ensured a seamless blend of style and performance.

Choosing the Zola brand for this retrofit project was a natural choice due to their Passive House Certification. These top-of-the-line products not only contribute to energy savings but also provide exceptional durability and timeless appeal. With their precise craftsmanship and attention to detail, they offer a seamless integration into historical brownstones, elevating their architectural beauty.

As a result of our efforts, the retrofitted historical brownstone now stands as a shining example of sustainable living. The Passive House Certified fenestration has significantly improved the property’s energy efficiency, reducing heating and cooling costs while enhancing the overall comfort of the space.

We invite you to embark on your own journey towards energy conservation and sustainable building. Let WindowFix be your guide in transforming your property into an eco-friendly haven. With our expertise in Passive House standards and our dedication to excellence, we ensure that every project achieves the highest level of energy efficiency and meets the stringent requirements of sustainability.
