Tel aviv is a dense city with little greenery within the city center and abundant hardscape. The buildings to not cast much shadow on the street and on each other; however the proximity to the sea allows for cool air breeze in the evening in some streets. The denser area of the city is defined by wide parks to the north and east, the sea to the west and continuous urban development to the south. UHI research has revealed the difference in temperature is within a range of 4-6 degrees Celsius between city center and the wide parks. Another research focused on urban vegetation revealed the impact of wide canopy trees on temperature in Tel Aviv is a reduction of up to 4 degrees Celsius. Also large parks act as significant “cool” islands. **3. Proposed measures** Considering the current urban design is advantageous to wind cooling, I would suggest planting wide canopy trees where it is possible and does not have a negative effect on wind cooling. This will achieve many goals: firstly, shading the streets and lower facades will limit surface hit gain. Secondly, large volume trees can reduce solar and long wave radiation reflections in streets canyon configuration; and lastly it will “clean” the air from pollutants and make the streets more temperate and livable. **4. Current Policy** Unfortunately despite the available information and empiric research there is no UHI policy in Tel Aviv at the moment.
