Energy efficiency and energy conservation in buildings
Energy consumption in the residential and tertiary sectors is especially high in developed countries.
There is a great potential for energy savings in these sectors
THE GENERAL FUNDAMENTAL RULE:
•to introduce energy efficiency technologies first•then to introduce modern options for energy conservation, i.e.:
new innovative technologies, including utilization of renewable energy, to reduce total energy consumption sufficiently.
TRADITIONAL OPTIONS OF ENERGY CONSERVATION IN BUILDINGS
To reduce the heat demand for heating purposes:• Improvement of a building envelope (including basement)
To reduce the use of heat supplied to the housing units:• Modernisation of thermal centres: automation, installation of heat meters• Modernisation of heat distribution• Introduction of individual heat meters• Modernisation of ventilation system
To reduce the use of fuels for heat production by modernisation of:• Thermal power stations and large thermal systems• Local thermal systems and boilers• Individual heat sources; which is usually done by switching from coal to gas
MODERN OPTIONS FOR ENERGY CONSERVATION IN BUILDINGS
• Introduction (or modernisation) of a design of the building with focus on the building envelope
• Utilisation of renewable energy
• Utilisation of waste energy
• Application of new methods of heat storage and heat recovery
• Reduction of waste energy and waste materials
Department of Eco-Building Engineering Institute of Fundamental Technological Research
The Department deals with:• building optimization, • modeling of structures and environment,• environmental acoustics,
• utilsation of renewable energy with stress on solar energy.
Department of Eco-Building Engineering Institute of Fundamental Technological Research
•Heat and mass transfer processes in buildings and composed media.
•Mutual interactions between environment and buildings - its influence on thermal comfort and energy consumption saving.
•Optimization of the building shape and structure and their elements, optimization of heat source utilisation in building sector.
•Thermovision analysis of building envelope.
•Solar energy devices and energy storage systems in buildings.
•Phase change for energy storage and transfer.
•Underground heat storage.
•Noise propagation in built-up areas.
•Noise generation in piping systems, acoustic in rooms of complex shape
•Composites with brittle matrix. Cement based materials.
