It’s not surprising that a 1970s bungalow on an exposed north-facing site might be draughty and burdened with high energy bills - but external insulation, a new heating system and a brand new roof can make all the difference. Lenny Antonelli reports.
Ill-considered attempts to upgrade a building’s thermal performance can not only fail to save energy, but can also create serious problems for occupant health and building structure alike. Leading green designer Joseph Little of Joseph Little Architects investigates the particular problems associated with dry-lining single-leaf concrete block walls
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.
In this fifth & final article in the series, Joseph Little compares simulations of several internal insulation options on common wall types, with worrying conclusions
An experienced timber framer with an eye for detail, Tim O'Donovan set about building a low energy stick-built home in the Cork countryside and achieved a staggering level of airtightness.

External insulation examined: the reasons why placing insulation outside makes most sense, with six example projects
The ESB's Home Insulation Scheme aimed to upgrade the homes of 1,000 pensioners on fuel allowance last year - it ended up reaching almost three times that number, reducing carbon emissions and improving the lives of many. Lenny Antonelli found out more.
A new timber frame house in the Wicklow hills is arguably the most airtight building ever built in Ireland, boasting wood fibre external insulation and an obsessive attention to sealing
The previous edition of Construct Ireland featured an article by leading green architect Joseph Little analysing the insulated dry-lined blockwork walls typical of many homes in Irish housing estates, looking particularly at moisture movement within the external walls. Continuing on from that article, Little looks at the implications of several ways of insulating houses of hollow block construction.
With over twenty years of design behind him, architect Martin Meyer has tackled plenty of big projects in his time, but his first home renovation challenge – to turn a dank 19th century red-brick house into a bright energy efficient home – was still eye-opening. Lenny Antonelli reports.
