Energy Retrofitting Isn’t For Everyone
Deep energy retrofitting has long been promoted as a solution to reduce energy consumption in homes. This approach involves making significant upgrades to the building envelope, such as adding exterior insulation and air sealing, as well as upgrading mechanical systems and appliances to improve energy efficiency. While this approach can yield significant energy savings, there are several reasons why it might not be the best option for every client.
First, deep energy retrofitting can be very expensive. Depending on the extent of the retrofit, it can cost tens of thousands of dollars to complete. For many homeowners, this cost can be prohibitive, and the return on investment may not justify the expense, especially in older homes.
Second, deep energy retrofitting may not always be the most effective way to reduce energy consumption. Depending on the home’s existing energy usage and efficiency, it may be more cost-effective to focus on smaller, targeted improvements, such as upgrading attic insulation or more efficient HVAC systems. These improvements can still yield significant energy savings, but at a lower cost than a full deep energy retrofit.
Third, deep energy retrofitting may not be feasible in all homes. Older houses, in particular, may have structural or architectural features that make it difficult or impossible to implement some of the energy-saving upgrades required for deep energy retrofitting. In some cases, it may be more effective to focus on other strategies, such as passive solar design or photovoltaic panels, to improve energy efficiency.
Fourth, deep energy retrofitting can be disruptive and time-consuming. Depending on the scope of the retrofit, it may require significant modifications to the structure and systems. This can disrupt normal use and livability, which can be a significant inconvenience for your family.
Finally, deep energy retrofitting may not always be the most sustainable option. The materials and resources required for a deep energy retrofit can be significant, and the process can produce a significant amount of waste. In some cases, it may be more sustainable to focus on reducing energy consumption through behavioral changes or low-tech solutions, such as shading devices or natural ventilation.
In conclusion, while deep energy retrofitting can be an effective way to reduce energy consumption in many homes, it may not be the best option in all cases. The cost, feasibility, effectiveness, sustainability, and disruption of the retrofit must all be carefully considered before embarking on this approach. In many cases, smaller, targeted improvements may be a more cost-effective and practical way to improve energy efficiency and reduce energy consumption.
