      (4)   For new commercial construction, the property must be designed to meet or exceed the energy performance required by the County building code that is in effect at the time a property owner applies to participate in the Program.
      (5)   The loan amount under this Program must meet the following criteria:
         (A)   Existing commercial construction. This subsection, 18A-35(a)(5)(A), shall be in effect for five (5) calendar years after the effective date of this amendment unless further legislative action is taken to extend it.

         (G)   any other financial or program document that the Director deems necessary.
      (4)   In addition to the administrative fees in Section 18A-34(c), the County may collect an administrative fee through the Surcharge to cover charges relating to lending, program management, billing, or collection. (2015 L.M.C., ch. 16, § 1; 2016 L.M.C., ch. 23, § 1; 2017 L.M.C., ch. 12, §1; 2018 L.M.C., ch. 31, §1; 2019 L.M.C., ch. 9, § 1; 2019 L.M.C., ch. 23 , §1; 2022 L.M.C., ch. 9, §1; 2023 L.M.C., ch. 21, § 1.)
Sec. 18A-36. Payment of surcharge; lien.
   (a)   The County must collect the amount financed through a Surcharge on the property owner’s real property tax bill and forward payments received by the County to the County designated program manager or, if there is no County designated program manager, to the lender no later than 30 days after the payment due dates for real property taxes. Payment due dates for semi-annual real property taxes are September 30 for the first installment and December 31 for the second installment, and for annual real property taxes the payment due date is September 30.
   (b)   After receiving written notice from the County designated program manager of the execution of a clean energy loan financing agreement, the County must add the Surcharge to the property tax bill.
   (c)   If the property owner sells the qualified property, the buyer must continue to pay the Surcharge levied on the annual property tax bill.
   (d)   The Surcharge and any accrued interest or penalty constitutes a first lien on the real property to which the Surcharge applies until paid. An unpaid Surcharge will be, until paid, a lien on the qualified property on which it is imposed from the date it becomes payable. The Surcharge will accrue interest and penalty and will be treated and collected like all other County property taxes. Any delinquency will be collected through the County Tax Sale process. The provisions of Title 14, Subtitle 8 of the Tax – Property Article of the Maryland Code that apply to a tax lien will also apply to the lien created under this law. Any delinquent Surcharge collected through the County Tax Sale process must be forwarded to the County designated program manager or, if there is no County designated program manager, to the lender no later than 30 days after the payment was received. (2015 L.M.C., ch. 16, § 1; 2018 L.M.C., ch. 31, §1; 2022 L.M.C., ch. 9, §1.)

(2015 L.M.C., ch. 16, § 1; 2022 L.M.C., ch. 9, §1.)
ARTICLE 6. BUILDING ENERGY USE BENCHMARKING AND PERFORMANCE STANDARDS.
Sec. 18A-38. Intent.
   The intent of this Article is to:
   (a)   implement recommendations of the 2009 Climate Protection Plan (EEC-2), 2013 Commercial Building Energy Efficiency study (Chapter 3.2), and support efforts of the Office of Sustainability to increase energy efficiency and reduce greenhouse gas emissions in the private sector and County buildings;
   (b)   engage the commercial and multi-family residential building sector with building energy information crucial to adopting energy conservation and efficiency opportunities;
   (c)   spur market transformation by making building performance transparent for the building and tenant market, allowing more accurate evaluation of energy costs and creating a competitive market for energy efficient buildings;
   (d)   strengthen the local economy by encouraging more efficient business operations and providing new opportunities for local businesses that provide energy conservation and efficiency services;
   (e)   recognize building owners that have made investments to improve their building energy performance and expand in-house capacity for energy management; and
   (f)   improve the energy performance of covered buildings through established building energy performance standards, therefore, reducing greenhouse gas emissions from the built environment and helping the County achieve its climate action goal of zero greenhouse gas emissions by 2035. (2015 L.M.C., ch. 51, § 1; 2022 L.M.C., ch. 13, §1.)
