  3. Location Sri Lanka is located off of south India. Colombo is about seven degrees north of the equator. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 3

  4. Climate Colombo features a tropical monsoon climate. Average temperature ranges between 81° and 84° F, and it receives 95 inches of rain annually. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 4

  5. Project Site The project is located in a low-rise industrial park adjacent to the airport. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 5

  6. Existing Building The project is a renovation of an existing two story factory building to EnerPHit standards. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 6

  7. Site Context Trees provide some shade but the majority of building is exposed to the sun. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 7

  8. Existing Interior Exposed steel structure with few partitions. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 8

  9. Cultural Context Users are accustomed to a greater diversity of interior and exterior configurations for building programs. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 9

  10. Design Analysis & Feasibility Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 10

  11. Local Design Exposed steel frame with extensive areas of glass infill. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 11

  12. Local Design Program areas pulled back within the structure to allow for open exterior spaces. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 12

  13. Local Design Some roof overhang. Decorative exterior shading panels. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 13

  14. Cross-Section The upper floor is the main production area features a broad column-free space. The lower area perimeter is pulled back up to a full bay in areas. Sri Lanka EnerPHit Industrial Building | NYPH 2017.06.16 Page 14

  17. Challenges Feasibility Study • Few specification on original drawings to establish baseline for cost and performance. • Difficult to establish historical primary energy use and cost as separate from industrial process loads. • No local distributor for typical Passive House products (tapes, air barrier, ERV etc). • Complex occupancy and usage patterns. Performance Goals • Certifiable to EnerPHit standards. Cultural and Aesthetic Goals • Provide mix of treated and untreated interior and exterior program spaces. • Maintain exposed steel structure design intent. • Create a regional model and local experience for future high performance development. Feasibility Process and Results • Extensive research and evaluation of loads and options. • 77% reduction in primary energy usage. • 6-7 year payback period.
