Full Description

Deep Energy renovation (DER) adopts a wholebuilding approach and achieves much larger energy savings than shallow energyrenovations that typically only included a small number (one or two) of upgrademeasures. DER includes the installation of high levels of insulation, usesrenewable energy technologies and minimises uncontrolled air leakage byachieving air permeability levels no greater than 5 m3/h.m2 to achieve buildingenergy ratings (BER) of at least A3. It can also include the installation ofmechanical ventilation in order to ensure an adequate level of controlledventilation for the occupants. The impact of energy efficient measures such asDER on indoor air quality (IAQ) is largely understudied internationally.Although research shows that improving the energy performance of a buildingimproves indoor temperature and occupant comfort, the impact on IAQ is unclear.In this research project the air concentration of pollutants, PM2.5,formaldehyde, carbon monoxide, carbon dioxide, BTEX along with temperature andrelative humidity will be measured in a sample of homes participating in theSustainable Energy Authority of Irelands Pilot DER programme. Post DER surveyswill also include an assessment of the performance of the ventilation installedas part of the DER. Preliminary results from a sample of 8 homes post DER arepresented here.
