Knowledge, Comprehension, Application, Analysis
This course focuses on the design of low-energy buildings and the dimensioning of passive systems, presenting not only existing technologies but also the design methodologies that students use to:
1. Investigate the thermal behavior of various materials
2. Identify and avoid specific pathologies of the building envelope.
3. Define strategies for natural ventilation and lighting
4. Design and dimension passive systems
5. Assess any design choice in the energy balance of the building.
6. Use computational tools for energy analysis
Energy policy and international standards relating to energy design in buildings, βasic principles of low-energy building design, building energy balance, international trend towards "zero energy consumption" buildings, available technologies
The lectures cover the following areas:
1. The energy issue - National energy system - International energy and environmental certification systems for buildings - Nearly zero-energy buildings Basic definitions (energy units)
2. Energy balance of buildings
3. Indoor environment of buildings - Thermal/visual/acoustic comfort - Air quality
4. Thermal insulation with emphasis on existing structures - Insulation materials - Calculation of the thermal transmittance coefficient of building elements - A/V calculation - Thermal bridges - examples
5. Use of heating degree days to evaluate design options. Solar radiation/natural lighting in the building environment (shading/lighting calculations). Glass characteristics.
6. Heating-cooling-ventilation-lighting systems (general characteristics, performance, structure, installation)
7. Presentation of KENAK – 1st exercise (simple building)
8. RES systems in the building environment (aesthetic functional integration). PV calculations
9. Exercise (KENAK) in a residential building with the aim of achieving a specific primary consumption
10. Measurements in buildings (environmental parameters, blower door, thermal camera, ligh
Students are assessed in the following ways:
1. Completion of a small design project at an individual level during the semester
2. Energy design of a building (group of 2 people)
3. Oral examination
