Summary

The course presents the main methodological topics of energy management in the building by emphasizing on the thermal energy requirements for the the users' comfort. The technical installations are modelled as well. Finally the economic and environmental evaluation methods are presented.

Content

Introduction: Heat energy flows in buildings.
Occupant comfort: various types of comfort (thermal, visual, air quality)

Thermal and visual Comfort: indoor/outdoor climate, parameters influencing the comfort, the equation of Fanger.Heat transfer: conduction, convection, radiation, steady state and transient conditions in the opaque and transparent elements of construction.Insulation materials: principles and types of heat and acoustic insulators.

Humidity in the building: causes, consequences, migration of vapor, model of Glaser.
Heat generation and distribution: heating energy (electricity, gas, district heating, fuel oil, coal, wood, heat of the environment, solar energy) ¿ heating equipments (heat accumulators, boilers, heat exchangers, heat pumps) ¿ heat distribution and transfer.
Envelopes design: protection against humidity, noise; heat losses through walls and roofs.
Energy performance diagnosis: energy expenditure ratio, energy signature, heat insulation, airtightness, measurement of airflow, efficiency of heat generation.
Economic Optimization and choices of energy options: general methods of techno-economic optimization, free parameters and sizing criteria, the annual costs of the various options and the search for optimal configuration, interpretation of the results and final choices.
Case studies ¿ Computer aided design of envelopes and thermal equipments of buildings.
