    The restaurant KOH is the first refurbished in Barcelona of a gastronomic  following the EnerPhit criteria. This international seal is the adaptation of Passivhaus for the case of rehabilitation. EnerPhit provides a protocol for buildings with very low energy consumption, combined with high thermal comfort. It is calibrated to achieve optimal energy rehabilitation in the life cycle of the building. In other words, the initial construction costs and energy consumption savings are valued throughout the life of the building. The restaurant KOH, which opened its doors at the end of February 2018, is being monitored by the team of Energiehaus, to be able to check that the adapted strategies and solutions really turn into the expected values ​​of low consumption (kWh) and thermal comfort and health (ppm CO2).

    The economic analysis of the offers of several contractors has shown that the extra cost to reach this standard is relatively low, of 5% in the case of the awarded contractor. The annuity that the promoter will pay (sum of mortgage and energy consumption) is from the first year lower compared to a less efficient variant, according to the Spanish building technical code. Our main strategies of action have been: continuous thermal insulation throughout the enclosure, Passivhaus type windows for warm weather, double flow ventilation with Passivhaus certificate, high air tightness and heat pump for heat and cold.
