TL;DR: In this article, the authors presented an overview of the EU residential building stock and focused on the Hellenic buildings, and the methodology used to determine the priorities for energy conservation measures (ECMs) in Hellenic residential buildings to reduce the environmental impact from CO 2 emissions, through the implementation of a realistic and effective national action plan.

TL;DR: The use of thermal infrared (IR) imaging is a valuable tool for inspecting and performing non-destructive testing of building elements, detecting where and how energy is leaking from a building's envelope, collecting data for clarifying the operating conditions of hard to reach heating, ventilating and air-conditioning (HVAC) installations, identifying problems with the electrical and mechanical installations under full-load operating conditions as mentioned in this paper.

TL;DR: The main obstacles for large scale application, beside the high first cost, are the lack of practical experience and acquaintance among architects, builders and planners with the design, control and operation of these systems as mentioned in this paper.

TL;DR: In this paper, a number of simplified design tools for calculating the cooling load and indoor air temperatures of a building, which also account for thermal mass effects, have been identified and classified.

TL;DR: In this paper, the authors present an overview of the method and software that can be used to perform building energy audits and assess buildings in a uniform way, perform demand and savings calculations, provide owners with specific advice for measures to improve energy performance, issue an energy performance certificate for existing buildings, and include some representative results from the pilot studies performed in several European countries.
