In an International Energy Agency collaborative project, an attempt has been made to establish indicators that unambiguously characterise energy use in a cold climate. Detailed information was obtained from 11 buildings in the seven participating countries. The project revealed that often there are no internationally accepted methods or definitions for the determination of different quantities. There is no general indicator that can on its own describe the energy effectiveness of a building.
This symposium covers materials, techniques and technologies successfully employed in energy efficient air barrier systems for residential and commercial buildings. Also looks at occupancy ventilation issues when developing functional energy efficient air barrier systems.
A potential conflict may exist between energy saving and good indoor climate. The present project is phase 2 of a 5-year research programme consisting of four phases, the objective of which was to develop energy efficient ventilation strategies that will provide both healthy and comfortable indoor climate and reduced energy consumption when compared to present standard.
Under deregulation, performance incentives to get utilities interested in investing in energy efficiency programs need to change. What works now and why?
