12 MATERIALS Planting and thermal mass NATURAL COOLING: By combining the right materials with planting, we can achieve natural and passive cooling GREY PROMENADE 10% shade Low humidity High temperature GREEN PROMENADE 80-90% shade Medium humidity Medium temperature AIR FILTER: Planting can be used to filter air. Dust and air pollution are trapped on the leaves and washed away with rain fall. 12 Dubai Sports Academy Design Development 2016

14 MATERIALS Surface pavement Materials are chosen because of both design and their microclimatic influence. The use of sustainable hardscape materials should be encouraged. Both locally sourced and low harmful environmental impact materials are to be used as much as possible throughout the design. 14 Dubai Sports Academy Design Development 2016 CONCRETE Concrete has a high mass value, and with a light surface it will reflect heat from sunlight. The material is unique because it s malleable and thereby cabable of shaping into any kind of geometri. GRANITE Granite is a strong and reselient material for pavement. It has a high mass value which is ideal for passive cooling. The hard surface is suatable for multiple treatments, by which a high or subtle expresion can be achieved with only one material. LIMESTONE The use of limestone for pavement has a long history in the region. In addition to its local source and aesthetic benefits it also has a very low specific heat, meaning it is ideal for hot climates.

16 ENERGY Passive ventilation and shading Straight lines of continuous trees block windflow and act as wind barriers, preventing air flow. Concentrated goups of trees orientated parallel to wind direction catch airflow and recude temperature Mid-level shrubs avoided. Trees with high trunks and broad canopies provide shade and do not obstruct windflow. 16 Dubai Sports Academy Design Development 2016

17 Overhead sun requires broad canopy trees for shading. Raised plantation provides 24hr shade and thermal mass cools walkways Raised terrain and vegetation pockets catches wind and creates cool airflow using transpiration Sunken shaded plaza uses the thermal mass of the concrete to cool air at low level.

20 ENERGY Low energy and intelligent lighting + + ENERGY SOURCE Using solar panels as energy support for the lighting, enables a sustainable and effecient energy source. The building roof top is sun exposed, and prevent visibility from ground. LUMINAIRE By choosing the right luminaires, its possible to achieve big energy savings. Some luminaires uses electronic-ballast technology to reduce energy consumption. FITTINGS Use luminaires with reflectors that can rotate around the lamp without changing the lamp orientation. Install floodlights with reflectors, which direct the light toward the field without tilting the lamp. This allows the lamps to operate at the highest possible efficiency. 20 Dubai Sports Academy Design Development 2016

21 + + DESIGN A propor light design and planning is the key to every succedfull project. Both in terms of energy consumption and eastetic. CONTROL Lots of lamps are using energy when not needed. A dimmable option allows you to control the settings and the amount of light and energy you want to use. 03 SUSTAINABLE STRATEGIES 21

22 WATER Intelligent Irrigation & Soil Selection Approximately liters of water is consumed in Dubai each year. 11% of this is used for landscape irrigation. The middle east has more than 2000 local plant species, but they are rarely used. We want to celebrate local species, culture - and save water! Local species and natural habitats create unique and resilient expressions, with very low maintenance. 150L/DAY 60L/DAY 10L/DAY DATE PALM THORN JUJUBE ARABIAN MORINGA 22 Dubai Sports Academy Design Development 2016

23 By choosing intelligent irrigation systems and the correct soil, the amount of needed water is reduced. Micro-Irrigation Micro irrigation or drip systems are generally more efficient than conventional sprinklers, because they deliver low volumes of water directly to plants roots, minimizing losses to wind, runoff, evaporation, or overspray Drip irrigations systems use 20 to 50 percent less water than conventional pop-up sprinkler systems and can save up to 30,000 gallons per year Soil Moisture Sensors Soil moisture based control technologies water plants based on their needs by measuring the amount of moisture in the soil and tailoring the irrigation schedule accordingl Proper soil selection and soil moisture sensors Intelligent Irrigation System Example: WaterBee SUSTAINABLE STRATEGIES Example: Microhumus - compost and soil engineering 03 23
