2ND PARAMETRIC DESIGN WORKSHOP LEIPZIG

2nd Parametric Design Workshop Leipzig

Thursday 5th of January to Monday 9th of January 

The workshop will be concerned with the development and optimisation of large area structures and climatic envelopes. Using rhino3D and grasshopper based tools such as Karamba and Geco/Ecotec parametric and iterative methods are to be used for system optimisation. 

Limited rapid prototyping tools will be available for physical modelmaking. 

Work in groups with people from Leipzig's School of Architecture and international experts and students! Architects, Designers, Engineers and other interested parties welcome. Working knowledge of Rhino3D and grasshopper required. No skripting skills necessary. 

The workshop will be jointly organised and tutored by 

Prof. Frank Hülsmeier 

Prof. Henning Rambow 

Prof. Dr. Alexander Stahr 

Guest lectures and tutoring by 

Clemens Preisinger (Bollinger•Grohmann•Schneider ZTWien GmbH, Wien - KARAMBA)

Dimitri Demin (Gartner Steel and Glass GmbH)

Martin Dembski and Christian Heidenreich, Uni Weimar

Henning Seide, FIlou Gmbh and HTWK Leipzig

Stefan Paulisch, WHZ, Fakultät Architektur

further speakers to be announced soon

Participants need to provide own laptop. Software licences will be provided for duration of workshop.

2nd parametric design workshop leipzig – task

The task

The aim is to design and optimize a roof structure for a market hall in the centre of Leipzig. The location of the hall will be on Wilhelm-Leuschner-Platz, which was the original location for a similar hall before the war. The whole area has never been rebuilt and forms now the largest open building plot near the city centre. Studies have identified a possible location for the hall on Grünewaldstraße opposite the park on Brüderstraße.

Andreas Wolf, one of the authors of the study will give a short introduction on the subject and define the location.

We are going to concentrate solely on the enclosure of the hall. All accommodation such as toilets, offices, storage etc. is assumed to be in free standing container type spaces in the inside of the hall without contact to the enclosure.

The enclosure has to fulfil two major requirements, which are to be  optimised by parametric iteration. 

1.) Optimisation of structural performance in order to reduce the weight of the structure. Other design criteria such as form, variation of height, focussing on entrances or urbanistic aspects can be included in the rationale of the optimisation.

2.) Climatic performance. This is to be optimised in two ways. 

a.) The enclosure is fully or in parts to be used as a solar power plant by covering it with PV cells. The areas covered by the cells need to have an optimum orientation towards the sun.

b.) Whilst the interior of the hall should be as light and airy as possible, direct solar radiation ist to be avoided wherever possible.

Lorry access

The hall can cover the area shown in the plan. The enclosure has to provide for gates for lorry access at two vageuely opposite endes of the hall. Gate size has to be 5 x 5m minimum.

Entrances and escape

Customer access is to be separate from the lorry access. One or more access points can be provided. Emergency escape has to be provided so that from any point within the hall an exit can be reached within 25m distance (the German building code states 35m, but this is taking into account the actual travel distance which could be obstructed by stalls and/or buildings in the hall).

Height

80% of the hall should have an internal clear height greater than 6m to accommodate single storey containers.

40% of the hall should have an internal clear height greater than 10m to accommodate double storey containers.

Model

A simple model of the surrounding area will be provided on a central server for use by all teams.

Software

Licences for rhino 5 beta, grasshopper (parametric design), karamba (structural optimisation), geco (data link to ecotect) and ecotect will be provided from the central server

Building Access

24 hour access to the building can be provided by guest access cards for all non HTWK-participants. We ask for a EURO 20 deposit on these cards, which will be refunded after return of the card.

Server Access

User name and password for the server will be distributed at the beginning of the work shop. The server can be accessed via WLAN in the rooms G431 and G432 used for the workshop.

Printing

Printers are available in G125. Printing costs are charged to the user. This service is only available to HTWK-participants. Please arrange within your team to use the printers. We may be able to provide a printer and printer server in the workshop spaces for fast uncomplicated printing.

Presentation

We are aiming to present the results of each group on Monday from 17 hrs onwards in the „Suedtreppenhaus“. Panels to fix plans etc. on will be provided.

Comments on Ecotect

Autodesk ecotect analysis 2011 can be used via a direct link through the geco plugin for grasshopper. Using this link a geometry defined in rhino or grasshopper can be used to generate an insolation and light calculation as well as a shadow simulation.

The link between the two programms is to be used to analyse the solar radiation on the enclosure surface and the daylight factor on the inside of the enclosure.

The aim is to optimise the relationship between design, structure and surface orientation and permeability to provide an optimum solar radiation on the enclosure for photovoltaik usage.

the optimisation can be carried out by the galapagos (evolutionary solver) comoponent within grasshopper or other iteration procedures. A thought out and accurately produced geometry reduces processing times for the exchange between programme components.

the calculation of the daylight factor has proven to be more processor intensive and does not alwasys seem to provide accurate results. the results can neverless be used as rough guidance for optimisation. Alternative methods, e.g. on the basis of raytracing software can be used if desired.

Coffee

A fully automatic coffee maker will be provided in the studio. It is a small machine so the reservoir needs to be filled and emptied from time to time. Coffee, milk and sugar will be provided. Please contribute with EURO 0,50 per cup to the costs of this.

HAVE FUN!
