Howard Laurence Liddell (7 June 1945 – 23 February 2013) was a British architect who was a pioneer of sustainable development and passive housing.
[4] Led by Liddell, Gaia Architecture produced a number of important and sustainable buildings in Scotland, including Acharacle Primary School, Glentress Forest Visitor Centre and Plummerswood.
[7] Liddell was principal and project architect for Glencoe Visitor Centre in Glen Coe near Fort William, Scotland, despite being highly critical of ecological tourism as "an oxymoron – you only explain what it is they are about to trample on".
[1] Acharacle Primary School, Argyll, Scotland also used a largely wooden construction, with natural ventilation and minimal heating requirements.
[12] His book Eco-minimalism – The Antidote to Eco-bling (2008)[13] criticised the tendency to add "eco-cliches" such as solar cells, micro wind turbines, and other expensive technologies rather than take the simple approach and build to reduce energy requirements.
