Abstract:
Sanierungsmaßnahmen an der Gebäudehülle erfordern hohe Investitionen. Gerade für kommunale Wohnungsunternehmen, die sozial verträgliche Mieten gewährleisten, ist es wichtig, dass in der Folge der Raumwärmeverbrauch zurückgeht. Ein Fallbeispiel zeigt, inwiefern das in der Praxis gelingt und wie sich gebäudeindividuelle Unterschiede bei sehr ähnlichen Gebäuden auf die Wirtschaftlichkeit der Sanierungsmaßnahmen auswirken.

Abstract:
Purpose The key purpose of this paper is to quantify the size of the energy-efficiency gap (EEG) for air conditioners at the household level in Delhi. Most of the studies in the EEG tradition broadly define EEG as the difference between the actual and optimal level of energy efficiency. The optimal level of energy efficiency is defined at the societal level (that weigh social costs against social benefits) and the private level (that weigh private costs against private benefits).

Abstract:
Energy-efficient technologies offer considerable promise for reducing the financial costs and environmental damages associated with energy use, but it has long been observed that these technologies may not be adopted by individuals and firms to the degree that might be justified, even on a purely financial basis. We survey the relevant literature on this “energy-efficiency gap” by presenting two complementary frameworks. First, we divide potential explanations for the energy-efficiency gap into three categories: market failures, behavioral explanations, and model and measurement errors. Second

In fullerides, the deviation of the superconducting energy gap from BCS prediction, especially close to TC, in experiments is an old, but not well-understood problem. If phase fluctuations are considered, the calculated temperature temperature of the energy gap is accurately consistent with the experimental one, and the deviation of the gap is a certain result.

Abstract Energy gap, the difference between the energy of the ground-state of a given Hamiltonian and the energy of its first excited state, is a parameter of a critical importance in analysis of phase transitions and adiabatic quantum computation. We present a concrete technique to determine an upper bound for the energy gap of a Hamiltonian H 0 based on properties of the set of expectation values of H 0 and an additional auxiliary Hamiltonian V. This formalism can be applied to obtain an effective criterion of gaplessness, which we illustrate with a concrete example of the XY model —a physic

Abstract:
A theoretical model1 of high-Tc superconductivity is analyzed. A superconducting transition in a system of local electron pairs interacting through the conduction band is shown to result in the emergence of two energy gaps: the tunneling gap (the gap in the one-electron excitation spectrum) ΔS (k) and the far-infrared gap (“pair gap”) Δp. The former of these gaps is large in comparison with the value predicted by the BCS theory and is sharply anisotropic in the k-space, while the latter exhibits an anomalous temperature dependence (in particular, it remains finite at the transition point Tc).
