Abstract:
The world would be a better place if housing was more accessible and affordable to everyone. But the reality is that supply and demand has made it too expensive for most — at least for the size house we’re accustomed to. If houses were smaller, more efficient and easier to build, this reality could change. This new tiny house concept is to reduce consumerism and provide an affordable and sustainable housing option. This work proposes the design and engineering of the Passive Eco - House, a 9.5-by-8 meters house that is energy efficient and bursting with natural light. The paper proposes a calculation method for a photovoltaic electricity supply a passive house built in a location in Bragadiru. Also, it present a spreadsheet application for a system of more consumers and lights (bulbs), fridge, electric household water pump. The calculations are simple and clear, the final results leading to information needed for building photovoltaic system: solar panels, storage batteries, inverter connector. Simplify the calculation leads to increased reliability and lower maintenance costs. Obtaining reliable performance of a photovoltaic system requires: consistent sizing calculation, technical knowledge, the use of good engineering practices when installing electrical equipment, develop and follow a complete and correct plan of operation and maintenance. The main equipments used in project are: Photovoltaic system (PV 6 * 250W, inverter, controller and battery bank Deep-Cycle), System DHW heating (heat-pipe tube panel 20, 200 liters boiler controller), Ventilation system with heat recovery or „put Canadian”, Solar walls and / or hot air collector
