Each project will require the Contractor to develop multiple iterations of the building energy model for the purpose of reducing building energy loads in the proposed design, as well as ensuring codes and standards regulations are met. The Contractor will engage in an iterative design process with each project team to implement building design options and choices, as well as factoring in environmental conditions based on the proposed location of the project. The Contractor shall work with the LEED Facilitator firm on each project to identify achievable performance goals in pursuit of LEED certification utilizing building energy modeling. The outputs of the building energy model will be used to track the progress of the pursuance of the project's targeted LEED credits and performance thresholds. Based on the results of the iterations of the model, the LEED Facilitator firm may recommend changes to the building design, of which the Contractor shall implement design choices in subsequent iterations of the building energy model. The Contractor shall also implement in the energy model building use factors such as proposed building operation hours, typical equipment, and appliance use, amongst others, for the purpose of simulating occupant behavior and the resulting impact on energy consumption. For each specific project, the Contractor may be required to develop multiple versions of the building energy model for comparing alternative building energy systems, such as HVAC, solar PV, hot and chilled water systems, etc. Metro may also assign the Contractor to develop building energy models for existing buildings. ........................................................................................................................................................................ Type No Response Required The Contractor must work with Metro and other project team members to meet specific objectives for each specific project. The role of the Contractor includes the following: * Develop building energy models to determine the energy performance, estimated energy costs, and estimated greenhouse gas (GHG) emissions of a particular building design. * Implement design decisions and conditions determined by the project team into the building energy model and work with project team members to improve the energy performance of the proposed design. * Work closely with the LEED Facilitator on each project to confirm the implementation of essential building performance criteria identified in energy modeling for the pursuance of identified LEED credits and sustainable project strategies. * Develop iterations of the building energy model based on design decisions made by the project team over the course of the project cycle, and track energy consumption and costs, and GHG emissions for each iteration. * When requested, develop multiple versions of the building energy model to compare design alternatives for building geometry, orientation, systems, etc. * Recommend energy conservation measures to reduce building energy loads to the project team. * Evaluate the impact of energy conservation measures that affect building design, construction materials, space layout, passive strategies, and mechanical and electrical equipment and systems. * Use building energy modeling to demonstrate compliance of the International Energy Conservation Code (per Metropolitan Code 16.08.010) (see attached Substitute Ordinance BL2015-1145) * Compare the proposed building energy model against a baseline building design under the same environmental conditions.
