Energy-Efficient Architectural Design Integrating Renewable Energy for Community Resilience in the Peruvian Amazon

Buildings in climate-vulnerable regions face critical challenges in reducing energy demand while supporting environmental and social resilience. In the Peruvian Amazon, off-grid riverine communities experience energy insecurity and seasonal flooding, threatening both the built environment and cultural continuity. This research presents a non-built architectural case study for an Indigenous community-based ecotourism lodge in Loreto, Peru. The methodology combines culturally informed passive bioclimatic strategies with design-stage quantitative calculations based on secondary sources, architectural programming assumptions, and a ten-year SENAMHI meteorological dataset (2014–2024). The proposed photovoltaic microgrid comprises 52 bifacial N-Type TOPCon modules (31.72 kWp) and a 286.3 kWh LiFePO4 battery system. Under the base demand scenario—defined by lighting loads, 180 standard outlets, an outlet simultaneity factor of 0.8, and an effective evening-use period of 5 h/day—the system is projected to cover modeled demand under average-month solar conditions. However, rainy-season performance remains conditional when bifacial gain is excluded, so the system is interpreted as preliminary off-grid sizing rather than evidence of continuous off-grid operation. Compared with a 30 kW diesel-generator baseline, the photovoltaic-battery configuration projects an 84.3% annual OPEX reduction. The design also estimates 570 L/day of biogas from a 2.0 m3 biodigester, 233,600 L/year of potable water savings, and proposes 152 Calycophyllum spruceanum and 15 Ceiba pentandra trees for NbS-based stabilization. These design-stage estimates suggest a reproducible research-by-design workflow for preliminary environmental, energetic, and socio-cultural evaluation of off-grid Amazonian ecotourism infrastructure.
