The Donald contracts with Acme to have anew office building built in New York City. The cost is $100 million dollars. In order to be energy efficient, it is contracted to be built with 3 ply windows. After the building is finished, The Donald discovers that Acme used 2 ply windows which are not nearly as energy efficient. Is this a breach of contract? If the cost to replace the windows is $5 million dollars, can the Donald consider the contract breached and refuse to pay the $100 million? If not what are his options?
