Exploitation of solar greenhouse in ventilation system of building

The paper deals with on-site measurements of energy benefits resulting from exploitation of a solar greenhouse, which was created in the attic under the southward-oriented glazed roof for pre-heating of the ventilating air.This conception of the solar energy utilisation is used in the residential complex of the senior citizen home in Svitavy, 60 km north of Brno. Based on the data collected with the use of an automation monitoring system during the heating season 2001-2002, the main characteristics of the investigated solar greenhouse operation were established.

Airflow performance characteristics of ventilators in hybrid ventilation systems

Part of the task in the design of ventilation systems involves selection and specification of system components - components sizes and expected performance characteristics or criteria to achieve specific ventilation objectives for anticipated environmental conditions. Careful selection of these components is required to ensure that they are able to react to changes in environmental conditions.

Air leakiness of non-standard housing : impact of upgrading measures

Sheffield City Council in the UK identified some dwellings of non-standard construction that needed to be refurbished. The refurbishment mainly involved applying insulation and rendering to the exterior surfaces of external walls and replacing old windows. The main aims of the refurbishment for the Council were to improve the condition and appearance of the dwellings and reduce conductive heat loss through the fabric.
