Utvikling av hallsystem for nødhjelp

Abstract

With changes in politics regarding refugee camps and how they should be managed enables changes in existing designs of equipment used. Along with developments in relevant technologies such as solar panels, gives incentives to think in new ways on shelters and hall systems for disaster aid. W. Giertsen Hallsystem AS (WGH) have long traditions on delivering equipment for disaster aid, and is currently one of the suppliers to NOREPS permanent stock of equipment used in case of emergencies world wide. NOREPS is a Norwegian organization which provides relief agencies with immediate support during emergency operations. WGH wants to investigate if there is new potential for their hall systems, based on the new developments in this market. Background information concerning WGH and its competitors is presented. Background is also given on the context where the hall systems are used. Based on the context study, the assembly crew is chosen as the user-group to focus on. Interviews with assembly crew and designers at WGH are done. Participation on the construction of an NG3 hall in Bergen is done to get practical experience with the challenges of setting up a larger hall. Based on these findings, several possible projects are listed. A focus on rainwater harvesting with its untapped potential is chosen for further study. The product to base a future solution on is chosen to be the NG1 system. A literature study gives further background on rainwater harvesting. A collection of existing products gives inspiration to new ideas. Through brainstorming and idea generation using sketches, two concepts stand out as good candidates for detailing. One concept prepares the existing hall systems for rainwater harvesting. The other concept presents an option of redesigning the typical hall-structure, making it more adapted to auxiliary systems such as rainwater harvesting (RWH), solar power and ventilation. A gutter solution is chosen as the concept to be detailed. The result is a simple yet efficient add-on for the NG1 system. The solution takes advantage of the existing supply chain of WGH and its sub-contractors. Materials are chosen so no new production technologies are needed. All the vital tools for assembly are already in place. The RWH system that is suggested has many positive side-effects, most importantly it increases the availability of potable water in a situation where infrastructure and supplies presents a challenge that needs to be solved.
