Abstract | Deck 1 is a 500 m² net zero energy office building, built in the southwest of France by Dugarry Architectes. The high insulated building structure and envelope use concrete and wood. The building is equipped with an intelligent lighting and solar shading system, an earth to air heat exchanger, a balanced ventilation system with heat recovery and 138 m² of photovoltaics on the roof. The website of the Deck 1 project shows the real-time performance of the building, updated every 5 minutes : indoor temperatures and humidity, outdoor temperature, energy produced by PV. Graphics also provide information about the energy consumed for heating, domestic hot water, ventilation and lighting (current values and totals since commissioning).
Lessons learnt | The primary energy consumption for heating, ventilation, domestic hot water and lighting is lower than 30 kWh/(m².year). Over 3 years, the PV system has produced about 21 000 kWh/year, i.e.1.7 times the energy consumption.
