Dimensionamento do sistema de aquecimento de água para uso residencial no projeto casa nordeste 1.0

Abstract

The sustainability and innovation practices applied to housing context is often profitable, which makes its acepptance important aon next years. This way, CASA NORDESTE 1.0 project, developed by students at Universidade Federal da Paraíba, aims to apply local technologies,by open source way and allowing its evolution concomitanly to the family as well. The point of the prototype’s development is the submission of the group to the international competition Solar Decathlon Latin and Caribbean 2019. This work dimentioned the water heating solar system to CASA NORDESTE’s using, in order to attend security and operation request established by NBR 15569 and NBR 5626 standards. After the forecast of dialy hot water demand and pointing of average climatic data, the calculation of hot water storage and collector area were done. Further the evaluation of the architectural model was needed to allocation of equipments by 3D AutoCAD 2016 model. Comercial models of boilers, solar collectors and auxiliary systems was reseached, in order to obtain a final budget. Lastly, a financial analysis of the project was developed by simple payback, NPV (Net Present Value) and IRR (Internal Rate of Return) methods.
