Sustainable Development Goals

2. Erradicar a fome - Acabar com a fome, alcançar a segurança alimentar e melhoria da nutrição e promover a agricultura sustentável.

3. Saúde de qualidade - Assegurar uma vida saudável e promover o bem-estar para todos, em todas as idades.

4. Educação de qualidade - Assegurar a educação inclusiva, e equitativa e de qualidade, e promover oportunidades de aprendizagem ao longo da vida para todos.

12. Produção e consumo sustentáveis - Assegurar padrões de produção e de consumo sustentáveis.

Learning Goals

The main goals are to prepare the students with the necessary competences in order to analyse and select environmental control systems of the buildings used in the agro-food sector, such as in the production sector (greenhouses or animal buildings) or in the conservation and transformation sector (storing facilities, cold chambers and drying facilities).

1. Introduction. Importance of the environmental control in rural buildings
2. Energy and mass balances. General and simplified equations; Project conditions; Heat transfer processes.
3. Psychometrics. State equations; Temperature and air humidity; psychometric map; Environmental control processes.
4. Thermal insulation. Heat transfer through construction materials; Thermal resistance and global heat transfer coefficient.
5. Condensation. Surface condensation and control methods.
7. Ventilation. Objectives; methods to calculate ventilation rates; Natural and forced ventilation.
8. Acclimatization. Heating systems. Cooling systems; Resolution of problems to determine heating/cooling needs for greenhouses, cold facilities and animal buildings.

Teaching Methods

Theory-practical classes. Theoretical classes followed by the resolution of application exercises.

Assessment

In accordance with best practices for assessment in higher education, the assessment methodology was defined in the first class, agreed upon by the professor and students. Thus, in the first class, two options were presented:
1. The final grade is the result of two midterm exams (continuous assessment, 50% each) or a final exam (100%).
2. The final grade is the result of a written exam covering all the material (50%) and assignments with presentation and discussion in (50%).
The selected assessment methodology applies to continuous assessment. The final exam (all semesters) consists of a written exam covering all the material taught (100%).
This academic year, assessment consists of:
- Continuous assessment system. The final grade is based on group work presented and discussed in classroom (50%) and a written exam covering all the subjects (50%), the first being taken during the classes period and the second during the exam period.
- Final exam (100%), both regular and special exam periods, consists of a written exam covering all the subjects.
Students who take both continuous assessment cannot take the Final Exam during the regular period. Therefore, the date of the written exam, will be coincident with the exam date.
PASS CONDITIONS
All written exams> 8 points and Final Grade> 9.5 points
