Zero Energy Building Research Alliance, or ZEBRAlliance, is a joint DOE-ORNL-construction industry initiative to develop and demonstrate new energy efficiency technologies for residential buildings, as well as fine-tune and integrate existing technologies, to lower energy costs. Construction of residential envelopes, the diaphragms that separate the inside from outdoors, can have enormous impact on whole-building energy usage. Consequently, post-construction thermal integrity assessment of the building envelopes in the experimental ZEBRAlliance homes is an integral part of the research and development cycle. Nondestructive infrared (IR) thermography provides a relatively easy and quick means of inspecting the experimental homes for thermal bridging, insulation imperfections, moisture penetration, air leakage, etc. Two experimental homes located in Oak Ridge, TN were inspected using IR thermography. The homes are designed with two different envelope systems: (i) Structural Insulated Panels (SIP home) consisting of an insulating foam core sandwiched between oriented strand boards, and (ii) Optimal Value Framing (OVF home) using innovatively spaced wood studs, which are designed to minimize the amount of wood framing, reduce thermal bridging, and lower material costs. IR thermal imaging was performed from both outside and inside of the homes. In this paper, IR images of roof and wall sections of the homes are presented and discussed with respect to identification of areas of thermal bridging and any insulation deficiencies.
