* '''Prep - Overview'''
** Heat Sources - Premise of Operation
*** Radiant floor section at perimeter in slab - 4 pipe passes (2 supply, 2 return) coming from end near electrical room
*** Ventilation air from ERV not heated, but tempered by recovery
** Paths of Heat Transfer
*** Walls, windows, slab uninsulated in middle, roof (incl. roof above middle room which is loft in Red Panda)
*** Some heating of ERV ventilation air required to bring to space temp
*** Interior partition to corridor
** Review trends from this week (space temp, water temp, etc.)
*** Space temp setpoint raised to 68F
*** Maintaining 68F at stat on 26F day outside; seems to be doing okay in general

* '''Hands-On'''
** Annex space pressure differentials
** Ventilation airflows
** Floor heating profile
** Temperature gradients in room
** Record of [https://drive.google.com/file/d/0B9bEzr-Y2qtaWG1FVWlPLU1pWjQ/view?usp=sharing Data and Observations]

* '''Brain Work'''
** Review observations/results in Red Panda Space
*** Uniform air temp of about 70F across room
*** Middle of floor about 68F surface temp
*** Stat mounted on exterior wall set for 68F resulting in 70F air temp throughout space
*** Electric heater in Red Panda running intermittently to supplement radiant floor, but was not running during Labs review (approx. a few minutes every 90 minutes or so reported)
** Other Annex Spaces
*** Noticed blob of slightly higher temp in middle room radiant floor segment (see thermal image); looks similar to how leak might appear
*** ERV air temp about 65F coming out of supply register by garage door
*** Inner garage door surface about same temp as corridor air temp overall since improvements made; metal rails only cold spots left

* '''Conclusions & Suggestions'''
** Joe plans to add insulation on top of radiant floor heating in electrical room; room does not need heat, so preserve it for other spaces.
** Joe indicates system does not appear to be losing water, so elevated temp blob in middle room may be imperfection in concrete and/or place where PEX piping comes closer to surface; unknown.
** Still some furniture and other items on top of radiant surface; some (metal) get heated up and then distribute their heat back to space; others (wood) appear to block heat more.
** Any additional research or calcs required?
*** None identified at this time.
