We are entering the last 6 weeks on this house extension and renovation in Kildare town. The image shows the kitchen area on the left and the new sunroom on the right. The ridge roof window will have automatic openers, a perfect way of cooling this south facing room. With significant insulation upgrades throughout the house we have to give as much thought to cooling as heating. Our client on another project completed 18 months ago said that she hardly put the boiler on all winter and enjoyed great heating from the winter sun. When I look at house design the very first thing I do is establish the orientation of the house to optimises the passive solar heating dimension of the scheme.
