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

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

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

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

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

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

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

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

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

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

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.
