A home with energy label D is moderately insulated and consumes a relatively large amount of energy. Certain energy-saving measures have usually not yet been implemented or are insufficient, resulting in greater heat loss and higher energy bills.
Energy label D is considered an unfavorable label. The lowest label is G, while A++++ is the highest achievable. A home with a D label often fetches less when sold than a comparable home with a higher energy label.
The energy label is determined based on fossil energy consumption in kWh per m² per year. Homes with energy label D generally have visibly higher consumption than homes that have modern insulation or sustainable installations.
A combination of outdated insulation, single glazing, limited draft sealing, and older installations often automatically leads to a D rating.
Fortunately, an energy label D is relatively easy to improve. With targeted, affordable measures, you can quickly move up to energy label C, B, or even A. Common improvement options include:
A home with a lot of drafts or poor ventilation loses heat. Weatherstripping and mechanical ventilation with heat recovery can have a significant impact.
Solar panels are one of the most cost-effective ways to quickly improve your label.
A modern heat pump or energy-efficient hybrid system can immediately raise your home's energy rating.
Would you like to know exactly which measures will yield the greatest benefits for your home? Renewable Partners can calculate this precisely, including costs, savings, and the expected result on your energy label.

The difference lies mainly in the degree of insulation and the proportion of sustainably generated energy. An A label can be achieved with good insulation and an efficient installation. For A+++, more is needed: a large proportion of the energy must be generated sustainably, for example with solar panels and a heat pump.
The energy label is determined based on the fossil energy consumption of the home, expressed in kWh/m² per year. For an A label, this value is between 105 and 160 kWh/m² per year. With good insulation, an A label is easily achievable. Homes built after 1991 often already have sufficient basic insulation to fall into this category. Solar panels are therefore not necessarily required to achieve an A label.

I have experienced Renewable Partners as a reliable and professional party in the field of sustainable energy. They think along well, are transparent in their communication, and deliver customized solutions that really meet the need.
Professional and readily available for questions. I am very satisfied with the service and can recommend the company. Kind regards,
While my energy label doesn't matter at all, new residents are going to renovate the entire house, Nik has still made a thorough and clear report of my old farmhouse. TOP job. Thanks
The energy label inspector is a highly skilled professional who knows his trade. We were helped well and quickly with his advice. The reactions of this company are praising the price, the lowest, and the service, downright TOP!
The recording was done carefully. All documents and construction dimensions were checked/recorded by the advisor Ronan van der Loo. And good advice was given. He finished the recording within 2 hours.
