Keeping up to building code changes, as well as the ever-changing environment of building materials, is essential and frequently requires the services of an experienced thermal performance assessor, particularly in the case of an existing building. The National Building Code requires that a specialist thermal assessment of a proposed structure is performed by an experienced engineer or surveyor.
The science of energy and energy efficiency
The thermal performance assessment of your property will be based on an analysis of how well your heating system is performing in the current climate. Thermal efficiency is measured in BTU per square foot (Btu/S) and a higher BTU/S is better. A thermal performance assessor can perform the BTU/S analysis for you and then come back and offer advice on what changes to make to increase thermal efficiency and reduce your energy bills. In many cases, there may not be any changes to be made to the design itself, but rather the structural components may need some upgrading. Thermal efficiency is important for all structures, including buildings, as the more efficient they are, the less energy they use, as well as the lower the heat loss.
An ideal candidate for a thermal performance assessor would have experience in designing both homes and commercial buildings. It is important that they are familiar with both the fundamentals and the latest developments in energy efficiency. They should also have experience dealing with a wide range of material systems and methods, including insulation, ventilation, heating and cooling systems, windows and doors, and all aspects of the building process. These include ensuring the design meets all legal requirements, and is environmentally sustainable.
