This process is consistent with industry approving modeling and building performance analysis standard. We will first provide an initial base model, and then work with the design team to develop and calculate the alternative <a href=\"https:\/\/en.wikipedia.org\/wiki\/Energy_conservation_measure\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>Energy Conservation<\/strong> <strong>Measures<\/strong><\/a> (ECMs). For LEED projects, this process will lead to the recommendations for ECMs to satisfy the <strong><a href=\"https:\/\/new.usgbc.org\/leed\" target=\"_blank\" rel=\"noopener noreferrer\">LEED Rating System<\/a><\/strong>. Finally, we will prepare related <strong><a href=\"https:\/\/www.usgbc.org\/content\/clone-leed-v4\" target=\"_blank\" rel=\"noopener noreferrer\">EA<\/a><\/strong> forms and other necessary documents for the Green Building Certification Institute (GBCI) or other jurisdictions.

While this process can quickly yield a model that may not be terribly accurate, but is perfectly adequate for comparing alternate scenarios \u2013 as relative differences are more important than deadly accuracy.<\/p>\n<h6 style=\"text-align: justify;\"><\/h6>\n<h6 style=\"text-align: justify;\"><strong>Schematic Design<br \/>\n<\/strong>During schematic design, CDL will develop an <a href=\"http:\/\/climaticdesign.net\/?page_id=1033\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>energy model of the facility<\/strong><\/a> based on the schematic design drawings. Output of this energy analysis allows the design team to optimize their focus on the most promising energy-saving strategies.

We will evaluate and document the building\u2019s envelope property selection, HVAC system selection, lighting system, and develop Energy Conservation Measures (ECMs) to illustrate the energy performance impact that would improve the status of the project. CDL will work with the design team to refine assumptions as necessary, simulate and re simulate the proposed design model, evaluate the results and select the most suitable ECMs to be applied for LEED credits. A full report will be submitted at this stage, showing findings and savings after comparing the energy consumption of the baseline model and the proposed model. This report will includes CDL recommendations regarding necessary revisions to the proposed design (if any) in order to satisfy the LEED requirements. CDL assumes the possibility of applying minor changes to the project in order to meet the desired percentage of energy conservation for awarded EA points.<\/p>\n<p style=\"text-align: justify;\"><strong>Construction Documents<br \/>\n<\/strong>CDL will revise the initial model and develop a <strong><a href=\"http:\/\/climaticdesign.net\/?page_id=955\" target=\"_blank\" rel=\"noopener noreferrer\">comprehensive energy model<\/a><\/strong> of the facility given the status of the final construction documentation, narratives, drawings, and design team correspondence. We will work with the design team to refine assumptions as necessary to formulate a complete and accurate energy simulation of the facility. CDL will evaluate and document the HVAC system selection, lighting system, controls, pumps, site lighting, service hot water, process loading, and other end-uses as required per LEED and ASHRAE 90.1 modeling protocol. We will also develop a detailed or ASHRAE 90.1 Appendix G baseline energy model.<br \/>\nAt this time, the project team will have the \u201cPre LEED Submission\u201d expectation for LEED Energy &amp; Atmosphere Credit 1 performance; barring any further changes, this will be the result that carries through to the final LEED Design Application submission to the Green Building Certification Institute (GBCI).<\/p>\n<p style=\"text-align: justify;\"><strong>LEED Submittal and GBCI Review<br \/>\n<\/strong>Once the final model is approved and the design team is ready to submit the design application for LEED certification CDL will prepare the related EA Credit forms and submittals documents and will upload them to LEED-Online. Upon submission of LEED the EA Credits, the GBCI will likely respond with clarifying questions. CDL will be responsible for answering any questions within the time allocated for review.<\/p>\n<p><a href=\"http:\/\/climaticdesign.net\/?page_id=698\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>Sample Energy Model<\/strong><\/a><\/p>\n<p style=\"text-align: center;\"><span style=\"color: #008000;\">Climatic Design = Energy Savings + Protecting the Environment<br \/>\nCall <a href=\"http:\/\/climaticdesign.net\/?page_id=91\"><em><strong>CDL<\/strong><\/em><\/a>\u00a0to meet your energy savings<\/span><\/p>\n<p style=\"text-align: left;\"><span style=\"color: #008000;\"><strong><a href=\"http:\/\/climaticdesign.net\/?page_id=48\" target=\"_self\" rel=\"noopener\">Return<\/a><\/strong><br \/>\n<a href=\"http:\/\/climaticdesign.net\" target=\"_self\" rel=\"noopener\"><strong>Home<\/strong><\/a><br \/>\n<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Energy modeling informs the design process, saving time and money by supporting early decision making.
