Eco-creations works according the Trias Energetica method. The Trias Energetica is a three-step approach to meeting the energy requirements for sustainable project.
Applying the method to buildings:
1. Limit the energy demand
Thermal insulation in buildings is an important factor to reduce the energy demand and to achieve thermal comfort for its occupants. Limit the energy demand can also involve a range of designs and techniques to address the main modes of heat transfer – conduction, radiation and convection materials and earth or soil. The effectiveness of insulation is commonly evaluated by its U-value. However, an U-value does not take into account the quality of construction or local environmental factors for each building. Construction quality issues include inadequate vapour barriers, and problems with
2. Use renewable energy
An additional reduction on space heating/cooling and on hot water can be achieved by the integration of sustainable energy into the energy supply system. A district heating/cooling system is the ideal starting point for a sustainable energy system. The heat in district heating systems is often obtained from a cogeneration plant using fossil fuels but increasingly biomass, geothermal heating and central solar heating are also used. District heating plants can provide higher efficiencies and better pollution control than localized boilers. Other sustainable heating techniques are solar thermal collectors and seasonal storage of energy in aquifers in combination with heat pumps.
3. Use fossil fuel as cleanly as possible
If there are no alternatives, then conventional fuels must be used as efficient as possible. In the ideal situation the use of conventional fuels will be diminished to zero.
