Fossil Fuels - Foreign Oil Dependency - ACCA Manual J ?

How can ACCA Manual J be in this heading? The DOE is requiring most jurisdictions to comply in the Federal Government’s efforts to reduce dependency on foreign energy imports. Over 85% of the energy used in the US is directly from fossil fuels.  Fossil fuels are a non-renewable energy source. The EPA is requiring reductions in fossil fuel emissions to help with the global efforts to decrease the Greenhouse affect. The cost of fossil fuels is increasing at a continuous pace and the need for alternative energy sources is becoming evident and more cost effective. The IECC (International Energy Conservation Code) is requiring increasingly higher building requirements to reduce, not only the energy footprint of consumers, but to protect and preserve the world’s natural resources.  Some more interesting Fossil Fuel Facts.

Why is all this so important and how does it directly concern you?  If you are building a new home, remodeling an existing home or adding an addition, you will most likely find the Building Departments requesting a heat load calculation or ACCA Manual J. They may also require a Manual D and Manual S.  The Manual J will have to comply with the design temperatures required by the jurisdiction.
