In addition to the facilities that may be financed under the Act, special taxes may be levied and bonds may be issued to finance and refinance the acquisition, installation and improvement of energy efficiency and renewable energy improvements to or on real property and in buildings, whether such real property or buildings are privately or publicly owned. Work on privately owned buildings and on privately owned real property may only be financed by a special tax levy if all of the votes cast on the question of levying the special tax are in favor of levying the special tax, or with the prior written consent to the special tax of all of the owners of each property that may be subject to the special tax, in which case the prior written consent shall be deemed to constitute a unanimous vote in favor of the special tax and any associated bonded indebtedness.
