Inquiry

The prerequisites requirements are to design the building project to comply with both- the mandatory provisions (Sections 5.4, 6.4, 7.4, 8.4, 9.4 and 10.4) of ASHRAE/IESNA Standard 90.1-2004 (without amendments); and the prescriptive requirements (Sections 5.5, 6.5, 7.5 and 9.5) or performance requirements (Section 11) of ASHRAE/IESNA Standard 90.1-2004 (without amendments). The project consists on installations for a public park, they are: an exterior amphitheater, one administrative office, exhibition space and a refreshment stand. The project is designed 100% "off-grid" with Photovoltaic (PV) renewable energy source completely, that means that there will be no electrical consumption from fossil fuels. A battery bank will provide the back up power. The project is 100% naturally ventilated. There is no mechanical ventilation and it will be operated accordingly. The ASHRAE\'s Mandatory provisions in Section 5: Building Envelope will not be met completely, outside air infiltration will be promoted, all windows will be opened during operation hours. The walls are designed to be permanently permeable to outside air. Accordingly, thermal transmission will not be possible to achieve in some of the spaces. Section 6: HVAC, will not be contemplated for being outside of the project\'s scope. Section 7: Water heating for service water will be designed with solar thermal water heaters. Therefore water heating in this project is contemplated as no electrical consumption. Section 8, 9 and 10 will be completely contemplated. Because of project\'s scope, complete compliance with ASHRAE would be incoherent. But being a 100% renewable energy, \'off grid\' project, its design is streamlined for energy efficiency, and obliged to operate as intended, as it will be demonstrated. Therefore we think we will meet outstandingly the EA Prerequisite 2 and EA Credit 1 intents, even if deviating from ASHRAE\'s provisions and requirements. Is our assumption correct?
