Interested in a Passive Home
Kilduff Construction is passionate about low energy building, low carbon building and Passive House construction. 
Our knowledge and experience on the subject is vast. We have completed many low energy homes and we are currently constructing a contemporary Passive House in Athlone which boasts U-Values of 0.1 on walls, roof and floor, 0.69 U-Values for windows and doors and an incredible 0.23 air changes per hour at 50 pascals for the house rigorously tested using the door blower test. The building has demonstrated an outstanding ability to harness and retain heat from the environment.
What is a Passive House?
A passive house is an energy-efficient building with year-round comfort and good indoor environmental conditions 
without the use of significant active space heating or cooling systems. The space heat requirement is reduced by means of passive measures to the point at which there is no longer any need for a conventional heating system; the air supply system essentially suffices to distribute the remaining heat require- ment. A passive house provides a very high level of thermal comfort and provi- sion of whole-house even temperature. The concept is based on minimising heat losses and maximising heat gains, thus enabling the use of simple building services. The appearance of a passive house does not need to differ from a conventional house and living in it does not require any lifestyle changes. Passive houses are naturally well lit due to large glazed areas designed to optimise solar gains, as well as healthy buildings in which to live and work due to fresh air supply through the controlled ventilation system.
