Can we get there by incorporating onsite renewables? Forum access is included with all levels of LEEDuser membership (basic and premium). Does the base building information need to be included in the minimum energy performance calculator, or is it sufficient to just include the tenant space? The Calculator seems only to be relevant where modelling is being undertaken. The recent version, v4.0, has the capabilities to measure sDA and ASE to achieve compliance with LEED v4 but this version is source-coded only. Obtaining these points requires following USGBC’s guidance document Reference Guide for Building Design and Construction. Alternatively, project teams may demonstrate compliance with the CEE Tier 3A commercial clothes washer criteria (MEF of 1.80, WF of 7.5). There is a separate AEDG Calculator you need to submit under Option 2. Our LEED Excel plugin can automatically fill in the LEED minimum energy performance calculator (MEPC) with construction information, glazing areas, occupancy schedules, lighting information and HVAC details.

As such the ASHRAE req, Energy Star Products and Lighting Power Density information can all be entered into the LEED Form via LEED Online. If building owners want to retrofit their projects to be LEED certified, the LEED Existing Buildings: Operations & Maintenance (LEED EB: O&M) rating system would be applicable in most cases. Do the required savings for this prerequisite (and credit) need to come only from building energy, or also process loads? Once criticized for lacking mandatory prerequisites for energy and water use, version 4 takes the management of these issues much further. However … You still need to do the lighting and Energy Star equipment for the prequisite. %%EOF h�bbd``b`�@�� Energy Performance.
