Focusing on capital cost without considering lifetime running costs
When constructing a home, it can be easy to focus solely on the purchase costs of products and systems and ignore the bigger picture.
Focusing on individual systems rather than outcomes
- Products and systems that deliver comfort include insulation, windows and heating. Considering them together may lead to you investing in more insulation, thereby reducing the required size of the heating system and its associated running costs.
- You may choose to invest in energy-efficiency measures such as LED lighting, low-flow showerheads, or control systems. This can result in a lower total energy demand, reducing the size (and cost) of the PV system required.
Failing to consider non-financial benefits
