New Energy-efficient UN Offices in Kenya Serve as Model for Sustainable Future – Ban

31 March 2011 –Secretary-General Ban Ki-moon today officially opened the new energy-efficient United Nations office complex in the Kenyan capital, Nairobi, calling it a model for environmentally sustainable architecture in Africa and beyond.

“This building is beautiful, comfortable and efficient. But more than any of that, this building is a living model of our sustainable future,” Mr. Ban said at the opening of the facility at Gigiri, which houses the new offices of the UN Environment Programme (UNEP) and the UN Human Settlements Programme (UN-HABITAT).

According to UNEP, buildings are responsible for more than one third of global energy use and are the largest source of greenhouse gas emissions in most countries. The Nobel Prize-winning Intergovernmental Panel on Climate Change estimates that emissions from buildings will rise to 11.1 billion tons by 2020.

The manufacture of building materials contributes a further 4 billion tons of carbon dioxide emissions annually, a figure that is increasing with the continuing rise in construction globally, most of it in developing countries.

“If our growing population is going to survive on this planet, we need smart designs that maximize resources, minimize waste and serve people and communities,” said Mr. Ban. “This facility hits all of these targets.”

From the 6,000 square metres of shimmering solar panels to the environmentally-friendly paint on the walls, the new UN offices – which comprise four buildings that can accommodate 1,200 staff – boast myriad environmental features, while capitalizing on the natural benefits of Nairobi’s climate.

The features of the energy-neutral complex include automated low-energy lighting for workspaces, energy-efficient computers and water-saving lavatories. Rainwater is collected from the roofs to feed the fountains and ponds at the four entrances, and sewage is treated in a state-of-the-art aeration system and recycled to irrigate the landscaped compound.

“This facility embodies the new, green economy I have championed for years now. An economy that can usher in a cleaner future, create jobs and spur economic growth,” said Mr. Ban, who was joined at the inauguration ceremony by Kenyan President Mwai Kibaki, UNEP Executive Director Achim Steiner and UN-HABITAT Executive Director Joan Clos, as well as other UN officials and dignitaries.

Calling the facility a “model for green architecture in Africa and beyond,” Mr. Ban said he hoped all UN offices will reach the very high bar set by those in Nairobi.

He added that the Organization is aiming to make its Headquarters complex in New York, which is currently undergoing major renovations after 60 years of existence, one of the cleanest, greenest buildings in the world.

While in Nairobi, Mr. Ban also held separate meetings with Mr. Kibaki and Prime Minister Raila Odinga. He also had a range of meetings with senior UN officials either based in Nairobi or visiting for the Chief Executives Board (CEB) gathering. That meeting, held twice a year, brings together the heads of the specialized agencies, funds and programmes in the UN system.

Also today, he launched his report on HIV/AIDS ahead of the high-level meeting on the topic at the General Assembly in June.

Green Revolution Gathers Steam in Kenya

The pressure on the environment from cooking is being blamed for a range of problems, from deforestation to creating gases contributing to global warming. And then there is people’s health: many die in the developing world from the fumes of indoor cooking. Entrepreneurs, engineers and scientists have launched many initiatives around the world to develop fuel-efficient and cleaner burning stoves. But they all share the same challenge: how can they meet local needs and tastes and keep the price of a stove affordable? Here is one example from Kenya of a successful stove and oven business that has become a regional success story.
A Kenyan entrepreneur has cooked up a fuel-efficient stove and oven that uses less of a precious national resource: wood from trees.
Renewable energy solution in Kenya
Most African households using fuel-burning stoves either cannot afford clean-burning fuels like natural gas or electric stoves, or do not have access to them. They are stuck having to burn wood or other materials like animal dung – collectively called biomass – on open fires.
As well as using up wood and contributing to deforestation, there is another downside to these stoves. The use of polluting fuel-burning stoves by half the world’s population – including 80 percent of rural households – is a documented contributor to a host of health problems. Poor households not only have to contend with the ill health effects of dirty water and poor sanitation, the fumes from burning dung, wood, coal or crop leftovers lead to the global deaths of more than 1.6 million people a year from breathing toxic indoor air (WHO).
Two solutions in Kenya are helping people to cook more efficiently (meaning less time wasted on gathering material to burn, and less fuel used) and reducing cooking time by using heat more effectively.
Invented by Dr Maxwell Kinyanjui, the Kinyanjui Jiko is a fuel-efficient charcoal oven that comes in small, medium and large industrial sizes. Made entirely in Kenya, the ovens are custom designed for a variety of environments, from domestic household use and on-the-go safari models to high-capacity models for micro-enterprises and large institutions. Cooks can use the ovens to bake, toast, steam or boil. And they are 40 percent cheaper than cooking with electricity and between 15 and 20 percent cheaper than gas.
Kinyanjui’s Musaki Enterprises Ltd.(www.reskqu.blogspot.com/2009/01/arboretum-project.html) has developed a reputation for pioneering work in developing fuel-efficient stoves and ovens. Its most popular success to date has been the Kenya Ceramic Jiko (jiko is Swahili for cooker), or KCJ, a cheap, simple and effective stove. The company was set up in 1992, but has been involved in international aid-funded research and development efforts since the 1980s.
“My dad was on a very good team of highly motivated individuals in the early 80s who developed the stove through pragmatism, logic and good old-fashioned ingenuity,” said his son, Teddy Kinyanjui. “He then set up the independent Musaki Enterprises.”
The KCJ uses a ceramic liner placed inside a metal container. The metal is usually recycled, often taken from 55 gallon steel drums. The ceramic liner stops the heat energy from simply escaping into the environment and helps to focus the heat on cooking. Simply adding the ceramic liner reduces the stove’s fuel consumption by between 25 and 40 percent. The charcoal or wood sits in the ceramic basin and the burnt ash falls through holes in the bottom of the liner.
The stove design was a result of international and Kenyan cooperation, and has become popular in many African countries, including Uganda, Rwanda, Ethiopia, Malawi, Niger, Senegal and Sudan. It is used in 50 percent of urban homes in Kenya and 16 percent of rural homes.
Musaki Enterprises say the KCJ stoves on average save between 1 and 1.5 tons of CO2 per stove per year compared to other models. In supermarkets, the KCJs retail for around US $5 and the Kinyanjui Jiko ovens start at around US $100.
The deployment of the KCJ stoves has helped in slowing the deforestation of the country, but has not been able to bring it to a halt because of population growth and poor re-forestation efforts, says Teddy Kinyanjui.
“The lack of forward planning in tree planting is making firewood and charcoal harder and harder to obtain,” he said. “Fossil fuels are unavailable or unaffordable. Tree planting must begin now on a huge scale for people to continue cooking.”
Teddy won’t reveal how profitable the KCJ stoves have been, but says, “I wouldn’t have gone to school if they didn’t sell well.”
“Well, more and more people keep buying the damn things as fast as we can make them, so I think our customers like them,” he said. “They really all seem to like that the stoves cook really well for really cheap and are very high quality.”
