Finally, large ceiling fans are installed in every room, even those using air conditioning. Ceiling fans ensure that even in the absence of the necessary breezes, the airflow needed to feel comfortable in the room is provided for the users. This solution significantly reduces the amount of energy consumed. The overall consumption of the ceiling fans and the split system (the latter used to cool the technical rooms) is only 3.7kWh/m².yr compared to a classic air conditioning system in a standard building consuming 80kWh/m².yr.
Federal roofing tax credit for energy efficiency
The 2009 roofing tax credit is part of a twofold plan rolled out by the US federal government. The first and most relevant of goals was intended to stimulate the economy by motivating Americans to replace their roofs with more energy efficient roofs, thereby creating jobs by increasing the demand for labor in the roofing, manufacturing, and construction industries. The other goal of the 2009 federal roofing tax credit was to reduce carbon emissions to the environment by requiring consumers to install Energy Star products on their homes in order to receive the tax credit; the installation of energy star roofing products in homes would reduce the consumption of electricity needed to maintain the desired temperature within the residence.
