In nature, the robustness and equilibrium of wild biomes come from their interconnections with other biomes and natural systems. While the goal is to make the captured piece of nature almost self-sufficient, creating this kind of artificial closed-loop biome always requires a lot of attention and support. In order to make the building truly symbiotic with its inhabitants and visitors, the Insectarium incorporates several bioclimatic and sustainable development principles. The first objective is to maximize the use of passive strategies. The stepped shape of the greenhouse volume is naturally oriented towards the south and allows above ground greenhouse areas to benefit from maximum sunshine throughout the year. The sawtooth geometry of the building roof allows for ventilation to happen naturally, every pitch having a series of automated operable windows that draws the hot air out in the summer. The large underground areas take advantage of the thermal mass of the earth to maximize the building’s insulation and naturally stabilize temperature variations. When passive strategies are not sufficient, mechanical ones are used to complete them. For example, advanced systems allow much of the heat generated in the greenhouses to be recovered and redistributed, heating the rest of the building. A range of additional systems such as misters, textile shades, motorized louvers, geothermal wells complete the array of potential tools. Roof water recuperation and the use of local, sustainable, VOC-free materials support the building’s bioclimatic approach and make the Insectarium a truly sustainable building. A LEED Gold-certification has been achieved.
