1 Thermal Imaging Survey Conducted at Nottingham [This copy has been edited to remove location details. The original document does not have a "Foxit PDF Editor" header on every page.] 27/01/2010 Written by David Farmer

2 Scope of the work: To determine areas of heat loss. External Temperature -2 degrees Internal Temperature 20 degrees Below are some key pieces of information which will help you to understand the thermal images and anomilies found during the survey. Thermal bridging occurs when the continuity of the building fabric is broken by the penetration of an element allowing a significantly higher heat loss than its surroundings. These bridges commonly accur around openings such as lintels,jabs and sills at wall/roof junctions, wall/floor junctions and where internal walls penetrate the outer fabric. Thermal bridges provide a ready passage of heat transfer to the outside air and allow a heat flow entirely disprportionate to their surface area. Gypsum Brickwork Thermal insulation Temperature scale: white areas being the warmest and black the coolest Indicates problem area Box area gives indication for temperature readings DELTA T Delt T gives the temperature difference between Ref Temp and spot 1 SP... Temperature Indicator Ref Temp Reference Temperature Mean Temp Rise Temperature difference between the box area and Ref Temp IR01 Profile tool gives temperature measurement in the form of a graph

54 Disclaimer: Thank you for contracting with East Midlands Thermal Imaging Ltd for your infrared thermography survey work. East Midlands Thermal Imaging Ltd reports the findings as interpreted by its trained thermographers. These findings have been developed in accordance with current practices generally accepted in the thermographic industry. Thermography is a powerful maintenance tool that allows us to see heat that is otherwise invisible. The purpose of an infrared thermographic survey is to locate and identify thermal anomalies in electrical, mechanical and building systems components and equipment. A thermal anomaly is an abnormal thermal pattern, an area or component that is either too hot or too cold. Often these thermal anomalies point to problem areas that, left unchanged, could result in expensive outages or failures, some of which could even become catastrophic. All observations presented in this report are time-dependent because conditions are continually changing over time. The information contained in this report reflects the conditions only at the time these observations were conducted. The inspection is also limited to the equipment in operation and successfully accessed. Temperature is however only one indication as to the potential severity of the problem. Other criteria, such as safety, equipment load, criticality of the equipment, availability of parts and manpower, scheduling, cost of shutdown and repair history often hold more importance than temperature in the decision making process. East Midlands Thermal Imaging Ltd will not be responsible for conclusions, opinions or recommendations made by others based on the data presented in this report. Although East Midlands Thermal Imaging Ltd makes every effort to locate, identify and report all thermal anomalies in the buildings inspected, the limitations of thermography, when combined with existing conditions and situations, prevent us from guaranteeing or warranting the results of our findings. This report does not purport to set forth all hazards nor to indicate that other hazards do not exist. Although the findings reported will sometimes lead you to the discovery of defects and/or conditions in need of corrective action or repair, East Midlands Thermal Imaging Ltd's report is not intended, nor shall it be construed, to warrant or represent the existence or nonexistence of any condition, defect or fact, other than the objective findings contained in the report. Any affirmations or representations by East Midlands Thermal Imaging Ltd, its agents or representatives, containing any probable conditions or defects purporting to cause the results reported, are mere expression of opinion only and are not intended to be relied upon by you. It shall remain your responsibility to discover the existence or nonexistence of defects and/or conditions in need of corrective action and/or repair and to hire trained repair personnel to perform such work. We assume no responsibility with respect to the continued operation of the surveyed systems of your facility. No warranties and/or guarantees, express or implied, are granted nor shall be deemed to be part of the services performed by East Midlands Thermal Imaging Ltd. East Midlands Thermal Imaging Ltd and/or it's agents or representatives shall not be liable for any personal injury, property damage or consequential or incidental damages, whether foreseeable or not, resulting from or arising from the performance of services rendered by this inspection or failure to inspect beyond the contract amount due East Midlands Thermal Imaging Ltd for said services.
