Why is building and district refurbishment important to reach our climate goals?
Refurbishing buildings and optimizing district heating and power systems significantly reduces energy consumption and greenhouse gas emissions, contributing to climate targets
Explain what role light weight constructions have as a refurbishment option. What are the advantages?
Lightweight construction serves as a refurbishment option by providing lighter structural components that simplify and speed up renovations, reduce building loads, and offer enhanced design flexibility and sustainability. Its advantages include faster construction times and easier handling, reduced costs through simpler foundations and less material, improved energy efficiency and structural durability, and a smaller environmental footprint.
Three materials as a refurbishment option where listed. Rank them from highest to lowest in the context of embodied energy and CO2 emissions.
New Concrete wall construction
New wood wall construction
New light weighted construction
The energy performance of existing buildings can be significantly improved by these strategies. Name 3 strategies
reducing transmission heat losses
improving the efficiency of the energy harvesting system
active strategies for energy harvesting
