THE YELLOW NEST, a benchmark corporate building for sustainability

We are pleased to present to you one of the most interesting buildings we have built at GMG and which has undoubtedly been born to be a benchmark for sustainability in our city. This is The Yellow Nest building located on Carrer Baldrich in Terrassa and headquarters of the Smilics group, which brings together a group of companies linked to the implementation of photovoltaic energy and digital technology applied to energy efficiency. The project was conceived from the start as an optimal energy container, requiring very little energy to operate and with a wide range of renewable energy production solutions. In this way for air conditioning, the building incorporates 12 geothermal wells with a power of 69 kW that work in combination with aerothermia equipment of also 69 kW, prioritizing at every moment the operation of the system that can offer the best performance according to external conditions. In the basement of the building we have built a Canadian well through which the renovation air enters the building and which manages to temper the outside air by about 3ºC before it enters the ventilation equipment, which obviously has also of enthalpy heat recuperators.. On the roof of the building we have installed a photovoltaic production field of shared generation which currently generates 20kW, but which will soon grow to 100kW of peak production. Currently the building is a (NZEB) Near Zero Energy Building, but when the solar field has been expanded it will be a PEB (Positive Energy Building). The building will then act as a shared generation plant capable of distributing its electrical production to neighboring buildings that will be able to purchase local energy. The home automation system regulates the level of DALI lighting necessary to compensate at all times for the conditions of natural light, the ambient temperature according to the occupation of the building, the relative humidity and the outside temperature. It also regulates the renewal of the indoor air according to the concentration of CO2 it detects, the closing of curtains depending on the solar incidence, the supply of air from the Canadian well, irrigation depending on the degree of humidity of the land and controls the level of rainwater collection wells. Finally, it also controls access, intrusion, camera circuitry and audio. The building collects 100% of the rainwater with a storage capacity of 20,000 liters which supplies the irrigation of all the vegetation we have planted there, both on the facades and on the roof. For all this, the building has achieved the Leed Gold Classification. From GMG we would like to especially thank the Pons family for the trust they have given us by taking on the challenge of designing and building this very special building.
