First Certified Passive House in South Asia by JPDA

The pioneering Passive House retrofit of a factory building in Sri Lanka creates a green economic catalyst and model for future sweatshop-free commercial buildings. Jordan Parnass Digital Architecture (JPDA) has completed the first Certified Passive House project in South Asia, proving that ultra-high-performance efficiency standards are achievable for buildings in any climate.

The Star Innovation Center is a product development facility located near Colombo, Sri Lanka. Intended to be a global model for the entire garment industry, the project sets a new high bar for sustainability, energy efficiency and worker comfort.

The project is one of only two certified Passive House factory buildings in the world, and annual energy consumption will be cut by over 75% compared to a conventionally “efficient” modern industrial building.

By choosing to renovate an obsolete building to Passive House standards, the project dramatically reduces the waste, carbon emissions and fossil fuels typically required for demolition and new construction, and promotes the client’s commitment to maintain high standards in social, environmental, ethical and safety compliance.

The Star Innovation Center is a pioneer in applying Passive House technology to a tropical monsoon climate, which features steady warm temperatures year-round but extremely high relative humidity. The majority of existing high performance buildings have been located in cool, Northern European-style climates where heating is the primary consideration.

Careful design and engineering of the building systems and enclosure ensures that workers enjoy year-round comfort in a workspace that provides abundant natural light, low humidity, filtered fresh air, and maintains temperatures near a constant 24 °C (77 °F).

Thorough testing of the airtightness and remote monitoring of the ongoing energy usage provide quantitative confirmation of the building performance, achieving projected operational cost savings for the client and vastly upgraded workplace environmental standards for the employees.

From the outset the agenda was to assemble an integrated project team including local architects, engineers, fabricators and builders to encourage technology transfer and demonstrate the feasibility of high performance building in the region.

By promoting the project’s goals and inspiring the local building industry JPDA has sought to establish a clear path to both reducing global carbon emissions and putting an end to worker “sweatshop” conditions.

Charles Komar, CEO of Star parent company Komar Brands expounds: “We are delighted with the comfort and performance of our Passive House building, and look forward to years of energy cost savings. Working with JPDA was a pleasure—Jordan and his team worked diligently to overcome challenges for the successful design and execution of the project.”
