<strong>Multiple</strong> <strong>benefits</strong> <strong>of</strong> <strong>in</strong>vest<strong>in</strong>g <strong>in</strong> energy<br />

efficient <strong>renovation</strong> <strong>of</strong> build<strong>in</strong>gs<br />

addition, the limited funds available restrict deeper retr<strong>of</strong>it <strong>in</strong>vestments, which typically<br />

give rise to the most significant energy sav<strong>in</strong>gs. 39<br />

This po<strong>in</strong>t does not only apply to energy efficient <strong>renovation</strong> <strong>of</strong> build<strong>in</strong>gs, but to ma<strong>in</strong>tenance<br />

<strong>of</strong> build<strong>in</strong>gs <strong>in</strong> general. A study from Denmark showed that the local municipalities<br />

were not mak<strong>in</strong>g sufficient ma<strong>in</strong>tenance <strong>renovation</strong>s to ma<strong>in</strong>ta<strong>in</strong> a susta<strong>in</strong>able build<strong>in</strong>g<br />

stock quality and condition. 40<br />

Engag<strong>in</strong>g <strong>in</strong> Energy Performance Contracts (EPCs) with Energy Service Companies (ES-<br />

COs) may overcome this structural barrier if the ESCO is will<strong>in</strong>g to f<strong>in</strong>ance the vast majority<br />

<strong>of</strong> the up-front <strong>in</strong>vestment cost. However, public regulation <strong>of</strong>ten <strong>in</strong>hibits the <strong>in</strong>volvement<br />

<strong>of</strong> ESCOs or the implementation <strong>of</strong> energy performance contracts. 41<br />

An additional barrier is that many central adm<strong>in</strong>istrations do not allow sav<strong>in</strong>gs from energy<br />

efficiency projects to be recycled <strong>in</strong>to the next year’s annual budget. There are very<br />

valid public governance reasons for do<strong>in</strong>g so, however it provides no <strong>in</strong>centive for local<br />

governments to undertake the <strong>in</strong>vestments if they obta<strong>in</strong> no <strong>benefits</strong> <strong>of</strong> do<strong>in</strong>g so. Given<br />

the high expected returns from energy efficiency <strong>in</strong>vestments, it should be economically<br />

feasible to construct a model that allows local governments to reap a share <strong>of</strong> the energy<br />

sav<strong>in</strong>gs (at least for a period <strong>of</strong> time) while channell<strong>in</strong>g the rema<strong>in</strong><strong>in</strong>g share <strong>in</strong>to the overall<br />

public f<strong>in</strong>ances.<br />

There has been considerable discussion about the appropriateness <strong>of</strong> the discount rates<br />

used by the public sector when evaluat<strong>in</strong>g the feasibility <strong>of</strong> public <strong>in</strong>vestments. The discount<br />

rates should reflect the cost <strong>of</strong> f<strong>in</strong>anc<strong>in</strong>g and the perceived risk<strong>in</strong>ess <strong>of</strong> the <strong>in</strong>vestment.<br />

As the price <strong>of</strong> government lend<strong>in</strong>g is currently at a historical low <strong>in</strong> most EU<br />

Member States, this suggests that the implied discount rates should be reduced compared<br />

to say 5-10 years ago. An additional argument has been put forward; that energy efficiency<br />

<strong>in</strong>vestments can be considered as a hedg<strong>in</strong>g tool aga<strong>in</strong>st volatile fuel prices, which is by<br />

far the most important risk <strong>in</strong> an energy project. 42 This implies that such <strong>in</strong>vestments<br />

should be evaluated by a different metric, and with a lower discount rate, than e.g. <strong>in</strong>frastructure<br />

projects with the same perceived risk.<br />

2.3 Barriers from market failure<br />

There is a vast amount <strong>of</strong> studies support<strong>in</strong>g market failures as a brake on pr<strong>of</strong>itable energy<br />

efficiency <strong>in</strong>vestments. This suggests that market failures constitute a real problem.<br />

Some caution is needed however. Several <strong>of</strong> the studies do not always factor <strong>in</strong> all the<br />

total costs <strong>of</strong> energy sav<strong>in</strong>gs projects <strong>in</strong>to the cost-benefit calculation, such as e.g. scare<br />

management time. Moreover, measures to evaluate ex ante ga<strong>in</strong>s from energy sav<strong>in</strong>g projects<br />

have also <strong>in</strong> certa<strong>in</strong> cases been shown to be too optimistic. Our bottom l<strong>in</strong>e from this<br />
