+ | ==== How we renovate matters ==== | ||
+ | Poor quality refurbishments can result in lock-in effects with suboptimal improvements typically left untouched for decades, if not generations. We simply cannot afford the resulting missed opportunities for energy savings and emissions reductions. Truly high performance refurbishment with a fabric first approach has the power to substanitally mitigate climate impacts while providing manifold other benefits (as outlined below). On a societal level, high-performance renovations will also dampen peak loads on our energy grids, boost our energy independence and facilitate out transition to a renewables-based energy supply, thus further contributing to our climate goals. | ||

+ | ==== Benefits of deep energy refurbishment ==== | ||
+ | |||
+ | When the focus of refurbishment is expanded to prioritise energy efficiency, we not only reduce energy consumption but also enhance comfort and health benefits while combatting energy poverty - a triple win. | ||
+ | |||
+ | * Living comfort significantly improved due to warm walls, floors, and window surfaces | ||
+ | * No draughts, condensation, | ||
+ | * Improved air quality due to constant supply of fresh air with a pleasant temperature | ||
+ | * Reduced operating costs due to lowered energy demand, thus protecting against fluctuating energy prices and alleviating fuel poverty | ||
+ | * Significant reduction of operational CO2 emissions due to a lower heating demand | ||

+ | Existing projects typically have quite individual challenges - both technically, | ||
+ | |||
+ | ==== Whole building complete retrofit ==== | ||
+ | |||
+ | A whole building retrofit refers to renovating an entire building all at once to improve its performance from the original state to a high performance building. This approach requires highest immediate investment costs but can still be the most cost-effective from lifetime cost perspective. | ||
+ | |||
+ | Example residential building: [[phi_publications: | ||

+ | |||
+ | |||
+ | ==== Retrofitting individual units ==== | ||
+ | |||
+ | Renovating single units allows for targeted energy efficiency improvements within a multi-unit building, thereby addressing the specific needs and constrains of individual spaces. This approach is only recommended if the entire building cannot be considered for renovation due to financial or logistical reasons (e.g. shared ownership). By focusing on one unit at a time, owners and tennants can experience immediate benefits such as reduced energy bills and enhanced comfort. Learn more about pilot projects | ||
+ | |||
+ | [{{ : | ||
+ | ==== Serial renovation (using prefabricated modules) ==== | ||
+ | |||
+ | Renovation using prefabricated Passive House modules, also called serial renovation, can offer a swift and effective way to upgrade building with minimal disruption. Prefabricated modules can be designed to meet specific energy efficiency criteria and pre-assembled offsite. They are then installed onsite, allowing for faster renovation, consistent quality control and a reduction of waste. | ||

+ | ==== Quick and easy retrofit measures ==== | ||
