The GEE approach
GEE works a new paradigm ahead from single
ecobuildings:
We work an urban conception trying to be
somewhere between
•
the “vertical city” very efficient from a certain
perspective of energy consumption, and
•
the “horizontal city” like BEDZEB
with an important condition: It must be an
approach viable economically (VPO, social
houses) and also considering aspects like
movility, materials life cycle…
GEE
Two cases
1995: First urban planning in Spain with
bioclimatic considerations (3500 VPO)
2005: Second urban planning with specific
normative included in the Plan Parcial
with general effect (9600 VPO)
GEE
1995-2000: Parque Goya
3500 VPO in three phases

First normative: “low” level of requirements

We get a THERMIE Project (UE) allowing,
basically:
the monitoring of three kind of buildings
the energy audit of the different buildings
projects in order to improve design
The main requirements of design were:

6: Envelope conductances
conductances:: 25/30%
greater than NB 79
7: Fenestration: better
than NB 79
4: Mínimum openings on N

5: Thermal collectors

PGoya
Some results and considerations
w Normal performance with gallery facing South
w It is clearly better than Est or North orientations
w South and North differences
w Even with greater insulation on North
orientation
w For summer comfort, eaves and cross-ventilation…
w …give very good performance
w All the mentioned has allowed very low energy
consumption
GEE
Monotony, a possible inconvenience
that does not exist. Some examples:
