LoginNew research shows that replacing low efficiency window air conditioners with high-efficiency units can produce measurable savings and can be cost-effective in homes with high air conditioning electricity consumption.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
The Norwegian solar low energy dwelling developed within Task 13 of the International Energy Agency's Solar Heating and Cooling Programme, is a two-storey row house apartment of approximately 120 m2 floor area.
Intermittent heating patterns, characteristic of Israel and other countries with a mild winter enable energy · conservation at the expense of very high peak energy consumption; · very low levels of thermal comfort; and surface condensation and mou
Two identical apartment buildings were built, one in Germany, and one in Sweden, in 1986. The idea was to create energy efficient housing at a low cost, using Swedish building technology and German heating and ventilation technology.
Passivehouses in Europe with a specific energyrequirement of less than 30kWh/(m2a) total for heating, tap warm water, ventilation and household electricity have been realized in Darmstadt, FRG. Four families live in the dwellings with extreme ther
The large number of innovative energy concepts which have been elaborated today to the stage of practicability open up new opportunities for contemporary architectural design.
The Majrovagen project is the result of a design competition, held by the City of Stockholm and the Swedish Council for Building Research in 1990.
The computer model SIN-BIP is built as a combined model that can calculate energy consumption, price and environmental load for a building to get an energy efficient building.
The aim of the study was to design and build a small house with 50% lower heating energy consumption than in typical existing Finnish small houses.
As part of a project financed by the National Foundation for Energy Research (NEFF), the Building Services Section at the EMPA examined the thermal behaviour of one building, with zero energy demands, located in a low energy housing estate in Waed
Domestic heating systems with a heat exchanger are generally assessed for efficiency by the ratio of primary energy input delivered energy output.
One of the important advantages of ordinary double glazing in comparison with single glazing is the avoidance of condensation at the inner surface during normal household activities.
A basic condition for low energy houses is a demand controlled ventilation combined with an air-tight building envelope.
Since the cost of energy is increasing sharply a trend to conserve energy in the indoor environment and in addition to improvements in thermal insulation, two possible solutions are adopted.
Flowfields around bluff bodies are characterized by complex distributions of the strain-rate tensor. Such flowfields can be analyzed with various turbulence models.
The paper considers issues pertaining to the capabilities and limitations of computational methods for multidimensional turbulent flows of the type encountered in fluids engineering.
This paper investigates the role of turbulence models in numerical calculations of flow over obstacles with second-moment closure models. Two models for the pressure-strain correlations are examined in the study.
