Report A3132.1 Page 7 Tasks The field assessment of exterior insulation performance at Test Hut #1 consisted of 17 tasks: 1. Acquisition of materials 2. Characterization of material properties 3. Preparation of site for installation of insulation specimens 4. Installation of interior reference insulation and instrumentation 5. Installation of specimens 6. Instrumentation of specimens and surrounding soil 7. Covering and backfilling 8. Final soil instrumentation and grading 9. Commissioning of monitoring system, replacement of faulty sensors 10. Monitoring and on-going quality review 11. Soil characterization and moisture content monitoring 12. Documentation of major weather events 13. Development of analysis methods 14. 2-D Analysis and presentation of results 15. 3-D Corrections 16. Uncertainty Analysis -- 17. Excavation of the specimens, physical observation and testing Duration of the Field Assessment The specimens were installed on the outer face of the basement wall in the 3`d and 4 week of October 1995. Thermocouples were then placed on the outer surface of the specimens. Backfilling took place on November 30, 1995, after all specimens had been installed and instrumented. Between installation and backfilling, the specimens were exposed to ambient conditions for about 4 to 6 weeks. The data acquisition system was then installed along with final instrumentation in the soil and surroundings. The data acquisition system was commissioned in tray..of. 1996. Official monitoring started on June 5, 1996 and ended on June 5, 1998: Instrumentation The instrumentation packWvnsisted of approximately 145 thermocouples, 2, RH sen+sors,.21 EMF sere site-built and calibrated heat flux transducers, - several junctimn boxes, a date, isition unit and computer. Monitoring of soil moisture content•was parformed mft" separate data acquisition unit. A detailed description of the instrumentation tpack,;ie is included in Appendix A.
