Figure 3: Images of the case study neighborhood
Main Characteristics
Type: residential
Urban form: Cul de Sac
Number of buildings: 6
Floors: 3- 4 floors for each building
Flats: 2 flats for each floor, total of: 48 flats.
Number of residents: 190
Total Area: 5300 m2
Environmental Readings
The environmental assessment of the given community basically revolved around four pillars:
The annual CO2 emissions of a single household unit are equivalent to 10 tons of CO2, per year.
The waste generation meets the ceiling of 1000 Kg a year of each household.
Water usage ranges around 160000 liters on a yearly basis.
Estimated energy consumption is delivered through 3000 Kw/h, of each unit.
Implemented Scenario - Technical Aspect
Taking the environmental Estidama integrated credits and reflecting them into on-site simulated
implementation has been based upon the following credit categories:
NS-3 – INTENT: Demonstrate enhancement of the ecological value of the site by planting native
or adaptive species. If 50% of the plants specified for planting are native and adaptive drought
and/or saline tolerant species, including a minimum of 5 different types of species, a total of 1
point will be rewarded. This is translated into the model by increasing the number of planted
trees within the neighborhood, around the main cul de sac entrance and through a central green
area that is to be implemented instead of the car parking. It is expected to positively affect the
CO2 emissions of the community, using a native and adaptive planting methodology will help
maintain the irrigation water demand at the lowest levels, thus increasing the plantation can be a
win/win solution without burdening the water consumption aspect in a negative way.
LC-R4- INTENT: Demonstrate an outdoor thermal comfort strategy has been employed to identify priority areas for shading and improve the outdoor microclimate for the community. The strategy is to consider the following as appropriate within the project’s specific context: Orientation;
Shading; Selection of high-albedo surfaces; Ventilation; Evaporative cooling; Radiative cooling;
and Thermal mass. Out of all the mentioned methods, this study will adopt the shading approach,
as it is found to be the only solution that can be amended upon the case study without having
a fundamental change, of which CityCAD can assess and evaluate. The mentioned solution, addressing the shade relation to the community is foreseen to affect the energy consumption of
all integrated households as one unit, nevertheless enhancing the personnel experience of residents within their place of daily living and activities. This will be implemented within the proposal
by adjusting the shade percentage within CityCAD to optimal levels, by using the shade option
of buildings, shade elements and all the planted trees that are to be installed within the proposal.
