36 37 Blue Green Solutions Guide Case study 4: Marlowe road, London Applying the BG systems approach to maximise energy efficiency and human comfort for a residential district. Background The architectural practice Pollard Thomas Edwards (PTE) was commissioned to complete the concept design for the master plan of a new, 41,000 m2 residential area in London. The plan’s aim was to demonstrate how integrated BG solutions can be employed to deliver a traditionally planned neighbourhood with a premier 21st century sustainability level. Key Performance Indicators for the design included urban heat island mitigation, low building energy consumption, enhanced outdoor microclimate, indoor comfort and the efficient use of water. BG Systems Approach The BG Team scoped and assessed design options via the use of the GDPM (see page 24). The preliminary analysis identified potentially useful interactions that could be exploited to inform the positioning of buildings and trees and the design of building envelope shading, materialisation and storm water management facilities. Trees were selected and positioned to 1) facilitate adiabatic cooling (along the predominant direction of the summer winds); 2) shade the building envelopes; and 3) mitigate heat island effects. Orientation and spacing of housing units was adjusted to enhance wind effects throughout the site by disconnecting them at strategic points to avoid wind blocking. This invention not only enhances natural cooling of the site through modifying the microclimate, but also by increasing convective heat transfer from the buildings. The result is an improvement of both the outdoor and indoor comfort during the summer period. Enhanced storm water management was achieved by tailoring the street design to facilitate better drainage, and harvested water was used for watering of the plants. Some of the buildings were designed with roof gardens that feature community gathering points Main Outcomes Applying the BG systems approach yielded a solar load reduction of 38.0 per cent, transmission reduction 16 per cent, a heat island effect reduction of 32.5 per cent and an outdoor microclimate reduction of 3.5 ⁰C for summer temperatures, relative to a standard development. As a result, the buildings’ summer energy consumption was reduced by 24 per cent. Moreover, these above benefits were realised without incurring substantial additional costs.

38 39 Blue Green Solutions Guide Case study 5: City of Šabac Application of the BG systems approach to the conception of a Master Plan for the regeneration of an entire city. Background BG Systems Approach Šabac (population 80,000) is a city in central Serbia. Situated close to three national borders and with two main highways in its vicinity, it has a long tradition of being a centre of trade. The city’s government is pursuing an urban regeneration agenda, as part of which they have enlisted the BG Systems approach to produce a visionary Master plan for the area. The aim is not only to transition to state-of-the-art urban design, but to deliver a redevelopment model (exemplar) for other towns across the region. The BG team ran workshops to familiarise the city planning teams with the BG systems approach: especially, the Goal Driven Planning Matrix (GDPM). The city’s targets were entered into the GDPM in order to facilitate a bespoke, BG Solutions based Master plan. Public workshops were held to gather further inputs and work-up candidate design concepts, via the use of the GDPM. The conclusions of these workshops are being incorporated into final version of the Master plan ("work in progress").
Main Outcomes The public workshops were highly valuable: they identified, for example, several new city resources that would not have been tapped into using a standard design process. A number of BG solutions were embedded into the plans. One solution of particular interest is the multi-functional use of irrigation canals in the city and parks (Figure 23 ). In the past, they would be empty for most of the time, and so would have no aesthetic and recreational value. Under the BG Systems plan, they deliver areas for recreation, biodiversity and flood protection 36 .
canals/streams is supplied from a shallow groundwater aquifer, driven by pumps powered by solar energy. It serves to maintain minimal water flow for supporting aquatic life throughout the year at no energy cost (Figure 23). The surrounding, vegetated floodplain area is used for recreation and to support biodiversity. Under conditions of heavy rain or high ground water level the floodplain retains its groundwater flood retention capacity. Because of the extended duration groundwater flooding, and clear water, flooded areas are used for water sport recreation activities. Thus, instead of being "reserved for flood storage" only, flood plains are converted into attractive open spaces for year round use.
