Housing energy efficiency is a critical aspect of modern living, impacting not only the environment but also household costs and comfort. Improving energy efficiency in homes involves a combination of design, technology, and behaviour changes aimed at reducing energy consumption and minimising waste.

Implementing energy efficiency measures can involve upfront costs, but many improvements pay for themselves over time through reduced energy bills. Government incentives, such as tax credits, rebates, and grants, can help offset these initial expenses. Challenges may include the need for significant investment, especially in older homes, and the complexity of some retrofit projects. However, the long-term benefits include not only cost savings but also increased comfort, improved indoor air quality, and a lower environmental impact.
