The move, he said, is in line with Rwanda's vision towards being climate-resilient and low carbon economy by 2050 and green building principles set up by Rwanda Housing Authority.
Solar water heaters are also part of green building technologies according to the Rwanda Green Building code.
"We urge more private investors to embrace Green investments which will help the country implement the recently submitted national climate plan and achieve vision 2050 for Rwanda based on green growth and low carbon economy," he said.
Green building technologies, for instance, shows that efficient lighting in buildings will require a funding of $6.4 million according to the plan while solar water heater (SWH) programme will cost $52 million among other green technologies recommended for buildings.
Rwanda Green Fund (FONERWA) and international funders will also continue to play a vital role in financing low carbon projects and programs.
