Dr Peter Rickaby writes on the varied and complex challenges of retrofitting older buildings.

Condensation within the structure of buildings is a lot more complex than condensation in a sweaty pub on a Friday night, writes building physics expert Toby Cambray.

In this first instalment of his brand new ‘Help Desk’ feature, architect and passive house designer Simon McGuinness of Dublin Institute of Technology invites questions on all aspects of passive house, retrofit and low energy building.

The primary reason for requiring airtightness in buildings has nothing to do with energy efficiency or occupant comfort, writes Helen Brown, head of building physics at Encraft — it's for the protection of the building fabric. 

Joseph Little and Calina Ferraro of Building Life Consultancy, and Manfred Kehrer of the Fraunhofer Institute of Building Physics will deliver a two day workshop on Wufi Pro hygrothermal simulation software in Dublin on 15 and 16 September.

This workshop will teach attendees to use Fraunhofer’s Wufi Pro software for simulating heat and moisture transfer through building fabric for the purpose of assessing risk and preventing interstitial condensation. The focus of the workshop will be on the practical application of the software.

In the fourth part of a series of articles on the condensation risks associated with insulating single lead dwellings, Joseph Little of Joseph Little Architects & Building Life Consultancy reveals serious problems with the approach taken by regulators, standards authorities and suppliers on the condensation risks associated with insulating single leaf walls.

Whether we reside permanently in an existing residence or are looking to build a new home, it is vital that we consider the well being of the occupants as well as the environment. RTE presenter Duncan Stewart stresses the importance of a healthy home.
