A Critical Appraisal of Germany's Thermal Retrofit Policy: by Ray Galvin

By Ray Galvin

Germany is noticeable as a pacesetter in thermal retrofit coverage and perform, yet how potent is its method? A serious Appraisal of Germany's Thermal Retrofit Policy examines this coverage in context and assesses its effectiveness. It reveals that technical constraints and the prices of retrofitting decrease the speed of growth, whereas making plans underestimates the impact of consumer habit within the kind of rebound and prebound results. A key discovering is that reductions could be maximized inside a coverage that knows the particular habit and motivation of families, the world the place so much power mark downs are already taking place.

The booklet indicates a brand new coverage paradigm that will motivate a greater stability of partial and finished retrofits, using loved ones habit adjustments in response to a greater realizing of gas saving motivation and gas rate elasticity. during this strategy, the thermal construction laws will be made extra versatile in order that policymakers would:

- advertise partial, transitional and cost-optimal retrofits, that are extra guaranteed to pay again via gas discounts in the event that they are acceptable to development typology and home-owner budgets.

- advertise complete retrofits for purposes except monetary achieve, focusing as a substitute at the convenience and environmental merits of energy-efficient homes.

- make investments extra seriously in teaching families to warmth economically, studying from the prebound impact with the intention to maximize the application of the houses they at the moment occupy, and base payback time calculations on genuine consumption.

The effects and findings of this booklet will be of curiosity to policymakers, researchers and graduate scholars alike.

Sample text

Yet current policies in European countries, including Germany, have yet to harness the potential of user behavior to energy savings. Insights into the effects of behavior on energy use were illustrated in a recent UK study. Sunikka-Blank et al. (2012) describe a thermal retrofit in a Council housing estate in Trumpington, Cambridge. Prior to the retrofit the home was monitored using data loggers and comfort surveys. 5 °C. The occupants were an unemployed couple and their three sons. They were using prepay meters for their energy costs, as their economic situation disqualified them from contract schemes.

The smaller of the two German studies (n = 151), BMVBS (2011), found that 42% of respondents felt the certificate provides useful information about a building, though 30% said they would prefer it not to be there, as it weakened their negotiating position. This is an indication that, for these cases at least, a good energy rating can influence the value of the property. The larger German study (n = 1,239), Amecke (2011), found that 35% of purchasers viewed the EPC for a property they were closely considering, and the certificate was actively promoted to 24% by the vendor or agent.
