Analysis of reduction of energy demands for Zero Emission Renovated Office Building by using thermal mass and ventilative cooling

The conclusion for the studied case is that given that the concrete structure was already built, the use of thermal mass is smart. However, when designing to achieve ZEB, increase of thermal mass in the form of concrete must be thoroughly thought as it would decrease cooling demand and shift temperature peaks, but will not be so beneficial for heating. At the same time increased thermal mass will increase the greenhouse gas emissions.
