ACCIONA tower. Hytasal

Previous studies for offices towers in ARI-DS-03 Hytasal. Seville.

The convenience and opportunity of the execution of the sector is revealed by the exigency of the fulfillment of the conditions and period imposed by the general plan.

As for the conditions of execution of the general systems, which must guarantee the suitable insertion of the sector in the city, at present they are totally executed.

The new plan, it recognizes opportunities for the implantation of new uses and urban functions, joining the zone of general  arrangement singular project of the south.

The industrial character  of this sector together with his topography, they provoke a certain discontinuity in the urban fabric, impeding the transverse connection between two principal routes  inside the city, since they are the avenue of the peace, and in minor measure hytasa's avenue.

The aim of the arrangement is to liberate soil by means of the construction in height, so that the free generated spaces turn into elements that give a meior quality of life to the urban fabric in his south sector.

The orientation of the building is determined by the regulation of the urban development planning. for what the idea of the project arises in an effort for adapting the morphology to the solar movement obtaining orientations like that separated from his fronts so that they could treat in different ways:

Front south. This one front is one of more problematic in our latitudes. The adopted solution consists of a double skin of glass that allows us a great glazed surface and simultaneously the overheating solves us thanks to the geometry of the exterior skin and the characteristics of the different elements.

Front north. Unlike the previous one this one front does not enjoy not of very good conference not of soleamiento directly, by what it is designed controlling the hollows to avoid losses, answering this way the design of the build to  criteria of  sustainability.

SUSTAINABLE OPERATING DIAGRAM

SAVINGS AND ENERGY EFFICIENCY

GUIDANCE

O1. Adaptation of the morphology to the solar motion

O2. Elimination of direct solar incidence inclined glass.

O3. Reduced sunlight through photovoltaic panels (hoods) and sunscreen glass.

O4. Control glazing and use of insulation in large opaque areas to reduce heat transfer.

LIGHTING

I1. Morphology of building more office space in the south wing, better conditions of comfort.

I2. Introduction of natural light in through the atria placed in front.

I3. Optimization of capture natural lighting facing south.

I4. Items reflective ceiling curtain wall facade and south to greater penetration of natural light.

NATURAL VENTILATION

V1. Ventilation atrium - effect of thermal gradient (ascent hot air).

V2. Cooling atrium with vegetation (transpiration temperature absorption).

V3. Natural cross ventilation day and night (between facades and atrium).

V4. Decreased thermal transfer ventilated facade (double skin).

USE OF RENEWABLE ENERGY

SOLAR THERMAL

T1. Hot water supplied by solar collectors.

SOLAR PHOTOVOLTAIC

F1. Capturing solar photovoltaics for grid injection (direct sales of energy).

GEOTHERMAL
