J. Dekkers, manager technical development:

"When the decision was made to install a solar water heater not all tenant were happy because they had to pay more rent. But now, the solar water heater is working and overall energy costs are lowered with twice the extra rent, all tenants are satisfied. Woonveste will continue its mission to install renewable energy systems in its building stock."
