Cost-optimal design for nearly zero energy office buildings located in warm climates

The paper shows the suitability of the methodology to support the design of cost-effective energy efficient solutions in new office buildings. Results show technical variants selection able to a decrease primary energy consumption by 39% and CO2 emissions by 41% at the lowest cost. They also illustrate how to design cost-optimal nZEBs for a warm climate in compliance with EU (European Union) policies.
