Platform on new construction, renovation, restoration and transformation
The recently completed renovation of 176 single-family homes in the Vogel and Bloemen neighborhood in Rhoon involved a wide variety of maintenance measures, combined with energetic interventions. The vast majority of the homes now have energy label A.
The great diversity of measures is partly due to the fact that the project consists of 8 housing types. “The houses with energy label E/F were built in the late 1950s, early 1960s , were moderately to poorly insulated and had high heating costs,’ says Wiebe Mulder, senior work planner at Hemubo Bouw, which supervised the renovation. ’Hemubo was selected by housing corporation Wooncompas as a construction team partner. We drew up an overall plan with Wooncompas and the architect, after which we were awarded the contract to realize this project.” After obtaining the required 70 percent approval from the tenants, Hemubo conducted home visits for a technical recording of the homes. This was necessary to take stock of how the work could be carried out at the home level. “On that basis, we jointly drew up a Plan of Action for each housing type.” Since the renovation was to be carried out in occupied condition, the work to be done and the expected inconvenience were discussed with the residents. “Our intention was to go through the homes in a train as quickly as possible, thus minimizing the inconvenience.”

Maintenance was limited for 20 homes because a long-term operating extension is not an issue at this time. Necessary maintenance was carried out so that the homes have a green energy label C. For the remaining 156 homes, the package of interventions went much further. For example, the roofs have been insulated with roofing sheets and fitted with new gutters and a rainwater and flue system. The exterior walls were provided with a layer of insulation, which was finished with a layer of stucco and stone strips. Mulder: “This has given the houses a ‘winter coat’ and they heat up less in the summer. Moreover, the facade has been renewed and enlivened. We were able to keep the existing window frames and fitted them with hr++ glass with ventilation grids.”

Various work has been done inside the homes. Wood floors were repaired or completely replaced where necessary. Asbestos-containing fibers were found under the floors, which were covered with foil and foam concrete, then insulation pellets were blown into the crawl spaces. Asbestos remediation was also necessary in other areas. “In the attic, we installed a box for the mechanical ventilation of the homes. In 95 homes, the central heating boiler was replaced with a hr boiler. The homes are thus already prepared for a gasless future. In addition, conduits have been installed for cables to the solar panels, which can be installed in the future. Depending on the condition, meter boxes, kitchens, toilets or bathrooms were renewed. Again, the end result is very pleasing. The residents are very happy with the final result.’’
