Design guide for social housing in rural Northern Ireland Creating rural places: Designing appropriate buildings Size and shape Solor gain In new-build rural social housing the size and shape of windows will be determined by the following three factors:- The size of the window should be determined by the orientation. In this example the larger openings are due south, to maximise solar gain. Smaller windows are due north, mainly for overlooking of the adjacent lane- way and to reduce heat loss. Again, this works well because the building is a single room depth. Fenestration and openable lights Traditionally, window openings were relatively small (usually less than 1.0m x1.8m). Window frames were divided into small rectangular panes using fine mullions and transoms, with the most common historic form of the double-hung sash window. In our rural landscapes a vertical emphasis on openings and individual panes is preferable. Larger horizontal window openings can be subdivided into a number of vertical elements. Con- temporary window forms can be successfully incorporated into rural social housing with careful composition and detailing. For example solid side-opening ventilation panels can be used to bring a variety of colour and texture to the elevations. Opening sections of windows significantly impact upon its appearance but provide essential functions such as natural ventilation and means of escape. A Lifetimehomes requirement for social housing is to provide at least one openable section per habitable room, capable of approach by a wheelchair user.
