Putting on your thermals
For any housebuilder or property developer, ensuring the energy efficiency of their development is important for regulatory compliance and customer satisfaction. Stuart Fairlie, Technical Director of Elmhurst Energy explains why.
The demand for energy efficient homes continues to increase, and with this comes a greater need to ensure that the design is reflected within the constructed property. Being able to prove the correct application of building products, ventilation systems or air-tightness of a home becomes increasingly important and the demand for site tests and inspections will continue to rise.
Part F of the UK Building Regulations requires that all 'purpose-provided' ventilation which includes MHVR Systems (Mechanical Ventilation and Heat Recovery Systems), as well as intermittent extractor fans, are tested to ensure they are operating efficiently and are fit for purpose. Air Flow Rate Testing and Commissioning results must then be submitted to building control, which contributes to the overall building compliance process.
With developers constructing properties which are more air tight, dwellings will need quality ventilation systems in order to reduce the risk of damp and mould build up. This trend will result in greater demand for Ventilation Inspectors, to provide a route to Part F compliance.
Moreover, those already offering on-site testing, such as air tightness testing, as well as SAP assessments will find that ventilation testing can complement these areas well, with a significant number of providers offering these services as a package.
Thermal Imaging Inspectors
Similarly, Infrared thermography is regularly requested by property developers and contractors to check build quality and establish the root of any thermal anomalies or defects that could result in unwanted heat loss. More and more building specifications are including these surveys within their schedules as a means of quality assuring a property.
Infrared Thermography or thermal imaging surveys are commonly used to assess the integrity of building fabric in order to diagnose problem areas and potentially reduce energy costs/emissions. By using this technology inspectors can quickly identify areas of missing or damaged insulation, and heat loss due to air leakage. Inspections are appropriate for both existing and new build properties (during and after construction). In addition to this, thermal imaging is often cited one of the best non-intrusive methods for checking insulation.
Qualified Inspectors will have the skills and knowledge to thermally inspect and assess dwellings and commercial buildings against a pass/fail criterion. Using a quantitative procedure they will present the thermal condition of a building envelope to clients (as either pass, fail or refer) using traffic light indicators for effective visual impact.
Building professionals can easily integrate thermal imaging for building surveys within their existing services, as an option for assessing the quality of insulation throughout a property. This type of survey is valuable in resolving disputes which involve heat loss and air leakage within buildings, due to the non-intrusive method which is undertaken.
By far the best way to get up to speed on Thermography, Ventilation and Air tightness is to attend a training course. Elmhurst now offers Air Tightness Testing, Thermal imaging for Buildings and Ventilation training courses.
There is little doubt the demand for energy performance measurement is growing, and energy assessors, such as Elmhurst members, are well placed to provide that for housebuilders and developers.
