Testing a method for the evaluation of the airtightness of ventilation systems in existing buildings | 2004 | English
This paper presents aspects of an office renovation project of the Social Insurance Institute (SII), the largest Social Security Organization in Greece.
A new thermal comfort guideline for moderate environments has been developed: the ATG guideline. The underlying method distinguishes between ‘type Alpha’ versus ‘type Beta’ buildings to provide for different adaptation effects.
Until the 1970’s most office buildings in central Europe were not equipped with mechanical cooling (airconditioning).
An increasing impact of ventilation and air-conditioning to the total energy consumption of buildings has drawn attention to natural ventilation and passive cooling.
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 envi
The impact of energy efficient refurbishment on the airtightness in english dwellings | 2004 | English
Fan-pressurisation method was used to test the air infiltration rate of 191 dwellings in England.
On the influence of the air infiltration heat losses on the energy performance of Italian residential buildings | 2004 | English
It is often discussed about the possibilities that more efficient windows offer to reduce the energy loads in residential buildings.
Sheffield City Council in the UK identified some dwellings of non-standard construction that needed to be refurbished.
Optimization of hybrid air-conditioning system with natural ventilation by GA and CFD | 2004 | English
This study aims at the development of an optimal design tool using a genetic algorithm (GA) andcomputational fluid dynamics (CFD).
Glass partitions, ventilation and thermal mass as retrofitting measures in an attached sunspace | 2004 | English
In this paper the effectiveness of retrofitting strategies in a sunspace attached to a one-storey building has been investigated.
The paper describes the development of unsteady pulse pressurisation techniques for measuring the leakage of buildings.
