22.214.171.124 Opportunities, Programmes, and Policies to Remove Barriers
Technological and social changes bring about opportunities to improve the efficiency
of buildings and appliances. A change in the production line for the manufacture
of an appliance offers an opportunity for introducing new energy saving features
in an appliance. Likewise, when buildings are sold, a city government may have
the opportunity to intervene and have energy saving features installed prior
to the registration of that sale. Targeting opportunities at a point where the
stock is likely to turnover physically or contractually can reduce the perceived
and actual cost to producers and consumers.
Governments have designed policies, programmes, and measures to tap these and
other opportunities, and in the residential and commercial buildings sector
they fall into nine general categories: voluntary programmes, building efficiency
standards, equipment efficiency standards, state market transformation programmes,
financing, government procurement, tax credits, accelerated R&D, and a carbon
cap and trade system. The last three items are generic and are not dealt with
in this section.
Voluntary programmes, such as Energy Star, which is operated by the United
States Department of Energy (DOE) and Environmental Protection Agency (EPA),
exist for both residential and commercial buildings, and appliances (Harris
and Casey-McCabe, 1996). The Energy Star programme works with manufacturers
to promote existing energy-efficient products, such as residential buildings,
personal computers, TVs, etc., and to develop new ones. Manufacturers can affix
an easily visible label to products that meet Energy Star minimum standards.
These programmes also facilitate the exchange of information between end-users
on their experience with energy-saving techniques.
Building efficiency standards focus primarily on the building shell and/or
the HVAC (heating, ventilation, and air conditioning) system, and in commercial
buildings also on lighting and water heating. Standards are being implemented
in California and other states in the USA, and also in Singapore and Malaysia,
and have been proposed or are on the books in Indonesia, the Philippines, and
Mexico (Janda and Busch, 1994).
Equipment standards require that all new equipment meet minimum energy efficiency
standards. Standards on household appliances and lighting have been in place
in the US for over a decade and are expected to be tightened between 2000 and
2005 (McMahon and Turiel, 1997). About 30 developed and developing countries
and EITs have voluntary or mandatory standards and labels in place on more than
40 household appliances (CLASP, 2000).
Demand-side management (DSM) programmes provide rebates, targeted delivery
of efficient appliances and lighting to low-income households, information campaigns,
and the like. These were pursued vigorously in some states in the USA. The deregulation
of the US energy supply sector has reduced the emphasis on these programmes.
Nevertheless, in several states that previously had these programmes, public
benefit funds for energy efficiency have replaced the DSM programmes, and are
typically charged to the electricity consumer on his electricity bill (Kushler
and Witte, 2000).
Financing programmes spread the incremental investment costs over time and
reduce the first cost impediment to adoption of energy-efficient technologies.
For commercial buildings, ESCOs offer energy savings performance contracts that
guarantee a fixed amount of savings and are paid through the cost savings.
Government procurement policies have accelerated the adoption of new technologies
in the USA and Sweden. In the USA, federal regulations regarding procurement
were amended in 1997 to limit purchases to equipment that falls in the top 25%
of energy efficiency for similar products (McKane and Harris, 1996).
To effectively enhance dissemination of improved cookstoves, policies, and
measures need to be put in place. The introduction of affordable credit financing
is widely recognized in Africa as one of the effective measures, which will
go a long way in removing the financing barrier. Assistance is still needed
in some locations on the design, introduction of centralized small and medium-sized
production centres, and marketing of energy efficient stoves, especially where
biomass fuels are commercialized typically as part of small enterprise
development. Further research and development work is also essential to increase
the efficiency of improved biomass stoves. For example, the British NGO, Energy
for Sustainable Development (ESD) is financing and supporting a team of Ethiopian
professionals working in household management and supply. It has achieved remarkable
success in developing and commercializing two types of improved biomass cookstoves
through an iterative approach of needs assessment, product design, redesign,
and performance monitoring (Farinelli, 1999). The team consists of consumers,
stove producers and stove installers, and pays attention to promotion, technical
assistance, and quality production.
