Passive and (very) low energy building
IBGE training, Belgium (2014). This classroom training organised by Bruxelles Environnement (IBGE) covers the applications to achieve a low energy building, involving the control of needs and the choice of both systems and energy sources. The objective of low energy, as well as the general concepts related to energy (insulation, systems, airtightness and ventilation), are addressed through an alternation between ex-cathedra courses and practical exercises.
Day 1: Introduction and ventilation
Main topics:
- Evolution of the energy standard;
- Calculation of air flow;
- Ground-coupled heat exchanger.
Day 2: Airtightness and insulation
Main topics:
- Calculation of heat loss;
- Construction methods;
- Thermal bridges.
Day 3: Systems
Main topics:
- Production and distribution of heat;
- Production and distribution of cold;
- Artificial light.
Day 4: Design strategies
Main topics:
- Loss minimization;
- Management of free contributions;
- Overheating minimization.
Day 5: Envelope design process
Main topics:
- Airtightness;
- Constructive nodes;
- Thermal bridges.
Day 6: System design process
Main topics:
- Primary energy consumption;
- From sketch to operation;
- Preliminary design study.
Day 7: From theory to practice
Main topics:
- Construction site visit;
- Orders of magnitude;
- Strategies for the future.
