Energy efficiency and renovations

Building maintenance is a long-term activity

The Housing Companies Act requires that buildings have a maintenance plan for the following five years. However, maintenance needs should be assessed for a longer time period to manage housing costs and housing company finances. The assessment can be made with the help of building maintenance records, an assessment of the condition of the building and various inspections in the building. It is advisable to update the building’s energy-efficiency survey and energy certificate in connection of the assessment of the condition of the building.

The energy consumption of a building is affected not only by the uses of the building and the building’s structures but by building technologies, heating and ventilation. If equipment is not maintained properly, energy consumption grows.

Renovation projects open new opportunities for energy savings

Energy regulations for renovation projects (2013) apply to operations that require a permit, to alterations to the uses of a building and to alterations to building technologies. The purpose of the energy regulations is to encourage properties to maintain their properties systematically. When a major renovation is carried out, opportunities for improvements in energy efficiency should always be reviewed.

It is advisable to make careful plans, because the regulations provide several alternatives: the thermal insulation of the building envelope can be improved, or the goal can be to reduce overall energy consumption. Improvements do not have to be implemented all at the same time, but they can be timed to match the property’s long-term maintenance plan. Energy-efficiency improvements should be economically, operationally and technically realistic.

The energy regulations for renovations present three different approaches. The first approach focuses on certain sections of a building, the second approach focuses on the energy consumption categories defined for building types, and the third approach focuses on the overall energy consumption (E-factor). Renovation projects can be carried out on the basis of the approach that best applies to the project to improve energy efficiency.

The studies and calculations required for the permitting process are determined according to the chosen approach and what measures will be taken. The building control authorities of the Helsinki Metropolitan Area have prepared a form to support project planning and the energy-efficiency survey.

Good maintenance is in the best interests of everybody

A well-maintained building retains its value. The building owner shall ensure that the property is in good condition, healthy and safe. Renovations and alterations shall be carried out with skill in order that the specific features of the building are retained and the cityscape remains unchanged. It is advisable to contact the Building Control Services to check what permit applies to the project, the demands of the project and the qualifications of the designers at the earliest possible stage of the project.
