During their Master’s program studies at Chalmers University of Technology, Jig’s co-founding members, together with other students, participated to the construction of Halo, a prototype house, in the context of a Solar Decathlon competition, between 2011-2013.

HALO is a socially sustainable home for four students, running on renewable energy from the sun. Over 25 students, Team Sweden, from Chalmers University of Technology in Gothenburg, Sweden designed and built HALO as their entry into the Solar Decathlon China which took place in Datong this past summer from August 2nd to August 13th. The students constructed HALO first in Sweden, dividing the house envelope in 30 prefabricated modules before disassembling and shipping the house to China for the competition.

HALO was designed using the underlying concept of shared space. HALO offers quality instead of quantity and giving added value while at the same time lowering environmental impacts. Keeping the total area low, a total interior space of 60 m², the students are offered large common spaces and smaller private areas. By sharing, our building is maximizing the use of the space, allowing the inhabitants to share habits, knowledge and friends.

The envelope has been designed using Passivehouse design principles, with heavily insulated walls, roof, floor and minimal openings. This allowed us to use a small simple HVAC system composed of off-the-shelf technologies and integrated into a simple flexible system.Resting on Scandinavian traditions, Halo focuses on the usage of wood, both for construction and surface finishes. The white interior works as an empty canvas, where the inhabitants are encouraged to paint their own lives. A mixture between fixed and movable furniture allows for shifting interior styles and room layout.

HALO placed 3rd overall in the Solar Decathlon China competition and 1st in communication, energy balance and hot water.Solar Decathlon is an award-winning program that challenges student teams to design, build and operate solar-powered houses that are cost-effective, energy-efficient and attractive. Each house is designed to compete in ten different contests, such as Architecture, Market Appeal, Engineering and Communications. Solar Decathlon was launched in 2002 and has been hosted in the U.S. and Europe in the following years. SD China 2013 the international competition took place for the first time in Asia.
