Monitoring performance

Cheap and easy to use, sensors not only record site phenomena and processes but also enable the performance monitoring of constructed designs. Ibuttons ($20–50) shown in Figure 3.15 are small durable computer chips with an internal battery that can be mounted discretely in soil or on paving to log periodic humidity and temperature. The graph shown in Figure 3.16, developed from ibutton recordings documents the fluctuating heat conditions in a suburban car park in Melbourne. This continuous data recorded peak temperatures but even more importantly for designers, highlights the ability of materials and spaces to cool down quickly, offering more rigorous understanding of the performative characteristics of heat, materials and spatial contexts. This accuracy is an important contribution to landscape architecture, which has often been guided by ‘rule of thumb’ principles that may not hold true in more complex contemporary contexts. For example this exploration of heat revealed that temperatures under trees were cooler during peak daytime temperatures but then retained heat for longer through the afternoon and evening.
