Transcript of Using Energy Efficiently
INNOVATIVE BUILDING SOLUTIONSARPIT SRIVASTAVA – ENERGY & RESOURCE EFFICIENCY
- Producing Energy EfficientlyUse of forward looking
technologies for the use of renewable energies, such as ground heat, solar energy and biomass
- Using Energy EfficientlyOptimization of the heat
distribution through surface heating/ floor cooling
- Reducing Energy LossesHighly efficient window and
curtain walling systems for heat insulation
