toggle navigation home solutions pulse services contact pulse air test our first offering to the building testing industry: a new solution to building airtightness testing. product information pulse is a pioneering approach to air-tightness testing which releases a low-pressure air pulse for realistic and accurate measurement of airtightness in seconds the solution has been developed by a consortium of specialists and academics in the energy efficiency industry. in joining forces with the university of nottingham as well as the national energy foundation, absolute air and gas and elmhurst energy; bts hopes to tackle the problems associated with current methods of air tightness testing. we are pioneering the new low air pressure method to bring huge benefits to developers, testers, building product manufacturers and building occupants. for more information on how pulse can help you, contact us key benefits of pulse pulse applications new build uncontrolled air leakage can increase a building’s heating demand by as much as 50%. it can reduce the efficiency of ventilation systems and adversely affect occupant health and comfort. quality assurance testing pulse is a low-skill test that site operatives can use regularly during construction. pulse can: • track changes in airtightness throughout the build process, bringing contractor accountability • reduce the risk of non-compliance, defects and the cost of remedy • give indication of build quality • raise on-site awareness of airtightness compliance testing we are working with government to bring pulse into part l1a of the building regulations, allowing for rapid, reliable, low-cost compliance testing retrofit it is estimated that around 65% of english homes need energy efficiency improvements. sometimes these improvements can cause their own problems with moisture control and ventilation. testing the airtightness of existing homes can inform retrofit decisions and prove retrofit post-installation performance. pulse’s low disruption, ease of use, and speed of testing makes it ideal for use in occupied homes. cleanrooms in critical environments like refrigeration chambers, cleanrooms and laboratories, the quality of air must be kept to an incredibly high standard: airtightness prevents contaminants entering or escaping unintendedly pulse offers bespoke systems for quick, low-skill and non-disruptive testing in these environments, improving efficiency and safety. back to top -- pressure pulse faq + what is the purpose of air tightness testing to comply with regulations? the purpose of testing airtightness is commonly perceived as a benchmarking comparison between buildings, however in reality the airtightness obtained is used to determine total ventilation rates for energy calculations in sap (and other energy modelling tools), and to a lesser extent for indoor air quality. as such, determining the correct airtightness is important for more than simple benchmarking and if incorrect can lead to errors in sap/energy assessments and also incorrect hvac system design/setup. + what is the pulse air test? the pulse technique works by subjecting a building envelope or enclosure to a known volume change and measuring the pressure response. the known volume change is introduced by releasing compressed air into the test space for a period of 1.5 seconds from an air tank which generates a flow rate through any adventitious openings whilst in turn creating a pulse in the internal pressure. during this pulse, a period of quasi-steady flow is established that directly gives the leakage characteristic at a specified level of pressure (where in buildings, our advantage over a blower door fan is that pulse can work at far lower pressures – 3 to 10 pascal’s – which are more representative of typical atmospheric pressures. after adjustment to still air conditions and a small correction for the effective flow rate arising from the compressibility of air, the result can be plotted or read in the same way as the blower door fan technique. + is the air pulse uniform throughout the house? how does the 4pa pulse deal with more complex building forms, for example? yes, the pulse of air is uniformly distributed very quickly. we have measured the internal pressure in the middle of buildings and also at multiple points throughout them (up to three storeys high) without noticeable differences. we have also done numerical analysis (using fluent cfd, fluid dynamic simulation software) that shows the pressure across the test space equalises almost instantaneously and certainly by the time of the analysis period. this is due to the fact that the pulse spreads at the speed of sound (approx. 340 meters per second) and is a long wavelength infrasonic frequency. just as with a conventional blower door test, the only requirement is that internal doors are kept open in order to ensure full and equal pressurisation. + does pulse generate a localised pressure that gets weaker as it disperses throughout the building? no, the pulse does not generate a noticeable localised pressure but it does require a sufficient volume of air to be released into the enclosure in order to be detectable; sometimes necessitating multiple pulse units in particularly large buildings. the pulse spreads at the speed of sound (approximately 340 meters per second) and is also a long wavelength infrasonic frequency that simply doesn’t get absorbed or slowed down within typical building environments in the same way shorter acoustic wavelengths do. the pressure transducer currently used for measurement within the pulse device samples at 20hz, giving us 30 readings in the 1.5 second pulse period (120 readings in the full 6 seconds of the test) and it is very clear in all of our data that the enclosure pressurises almost instantaneously, quickly and consistently reaching a quasi-steady state before then decaying. although the pulse or air does not get weakened by the building form, the volume of air released is relative to the size of the enclosure and its airtightness. for equal pressure distribution within very large buildings we can therefore tether multiple units evenly throughout the building and release them simultaneously. + how is q4 calculated? q4, (the air leakage flow rate at 4 pa), is obtained in the same way the blower door test obtains the q50 (leakage rate at 50 pa). a curve fit is made to the plot of leakage against pressure difference, and then the leakage corresponding to 4 pa is calculated. this can be done using either the power law or quadratic equation, and in practice (with experimental data) is simply a case of flipping the axes to convert between them. while the quadratic equation has been shown both numerically and experimentally to provide a better model of low pressure leakage, in practice it doesn’t really matter that much which is used for fitting measured data as long as it isn’t extrapolated outside the measurement range. + how do the results compare between a blower door and pulse test? in order to make a direct comparison at the same pressure level, either one or the other has to be extrapolated and significant uncertainties are introduced to the results as a consequence of this forced extrapolation (see comments below on using a single ‘n’ value). in deciding whether it is best to extrapolate pulse up or the blower door down, it is necessary to question what is the point of airtightness testing – essentially it is to try and infer the infiltration that happens under natural conditions, of which 4 pa is considered a typical pressure difference. therefore, a comparison at 4 pa is the most relevant as the use of 50 pa is simply a former compromise made as there was previously no technically accurate way of measuring it reliably. however, if it is accepted that the blower door cannot give accurate results below 10 pa (either directly or through extrapolation) then comparing them at 4 pa could rightly be seen as biased towards pulse. therefore, per
