Sunspace is a relatively recent term which describes something similar to a winter garden, but for reasons relating more to passive or solar design principles and building performance than entertainment or horticulture.

Also a south-facing glazed area, and similarly to winter garden but more specifically not part of the thermal line or fabricenvelope of the building. The space acts as a thermal buffer-zone in the winter, improving the thermal performance of adjoining walls and can preheat colder outside air during the day before it enters the main building.

On milder summer days in acts as a warmer sunroom, whilst during peak summer daytime heat temperatures may become naturally much higher, with some potential for heat exchange (sun as pre heating hot water) the space itself should be balanced with suitable extracts (potentially via heat exchangers ) or high level opening vents.

One example where extensive use of south facing fully height glazed sunspaces contributed to efficient performance of a building was in the Eco-development Beddington Zero (fossil) Energy Development known as Bedzed, located in South London. These provide buffer zones to the external wall space and contribute to the low heating requirements for the buildings, the spaces had high level vents which were value engineered which led to over heating issues in 2022.
