Energy-intensive building
The Star Innovation Center is a product development facility located outside of Colombo in Katunayake, 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.

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 a new build, and promotes the client’s commitment to maintain high standards in social, environmental, ethical and safety compliance within the global fashion industry.
It is the first Passive House project in South Asia, and one of only two certified Passive House factory buildings in the world. Annual energy consumption will be cut by over 60% compared to a conventional “efficient” modern industrial building. and a payback period of 6-7 years is expected. This project also includes cutting-edge sustainable technologies, like a “heat pipe” system that reduces dehumidification energy use by 90%.

The project 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. 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).

Because the Star Innovation Center is a milestone in industrial energy efficient retrofitting in a tropical monsoon climate, the Passive House Institute awarded the EnerPHit Pilot Project Certification. Thorough testing of the airtightness and remote monitoring of the ongoing energy usage provide quantitative confirmation of the building performance, confirming projected operational cost savings for the client and vastly upgraded workplace environmental standards for the employees.
From the outset the idea 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 and inspiring the local building industry there is a clear path to both reducing carbon emissions and putting an end to worker “sweatshop” conditions.

  • 680,00 kWhpe/m2.year

    • Other

    The following values represent the renovated building's performance: Cooling and dehumidification demand: 183 kWh /(m2a ) Cooling load: 21 W/m2 Calculated according to PHPP The primary energy demand of 344kWh/m²a includes cooling, dehumidification, auxiliary and household electricity as well as domestic hot water, and is divided as below: - 27% cooling (sensible) - 20% Lighting - 20% Sewing Process Loads - 16% PCs / Office equipment - 7% Cooling (latent) - 6% Aux. elec & Summer ventilation - 4% Domestic Hot Water A breakdown of the energy consumptions before the renovation is not available. Only the final (260 kWh/m2a) and primary energy (680 kWh/m2a) demands could be verified and presented.

Envelope performance

    Exterior wall: U-value = 0.329 W/(m2K)

Systems

    • No heating system
    • Individual electric boiler
    • Fan coil
    • Double flow heat exchanger
    • Solar photovoltaic
  • 10,00 %

    • 5 units with heat and humidity recovery
    Average for all 5 ventilation units:
    72% heat recovery
    70% humidity recovery
    0.7Wh/m³ electric efficiency
    Manufacturer: DESICCANT ROTORS INTERNATIONAL PVT LTD., ARCTIC INDIA HOUSE, 20, RAJPUR ROAD, DELHI - 110054 (INDIA)

    Additional cooling and dehumidification (after the ERV) is beeing done via fan coil units which cool the air to a very low temperature in order to dehumidify it. The air is then reheated using Heat pipes with Heat Recovery. The heat pipes work in collaboration with the solar pannels on the roof which save costs in comparison with the classic electrical reheat systems.


    Generation of renewable energy: 48340 kWh/a which is 19 kWh /(m2a) based on the projected area of 2549 m2
    Renewable energy demand (PER demand according to PHPP): 164 kWh /(m2a) based on the used area on cooling/dehumidification installation, domestic hot water, household electricity and auxiliary electricity

Urban environment

    The project is located in a low-rise industrial park adjacent to the airport. 

    Trees provide some shade but the majority of the building is exposed to the sun.
