In highly insulated residential buildings, complying with the Passive House Standard, the space heat demand can be covered by air heating at air flow rates given by air quality requirements, without the need for additional air re-circulation or fo

IEA ECBCS Annex 36 : retrofitting in educational buildings - REDUCE 25 case study reports from 10 different countries | 2003 | English
The IEA ECBCS Annex 36 deals with the energy retrofit of educational buildings.
An evaluation of natural ventilation and comfort of a multi-storey university office building | 2003 | English
Ventilation and comfort assessment of buildings is not a new practice in post occupancy evaluation (POE) of buildings.
Effective weather resistive barriers (WRB) perform important functions in retarding waterentry into walls and in controlling water vapor movement as well as the amount of energyattributed to air leakage (Burnett, 2000; Weston et al 2001).
The Norwegian Building Research Institute (NBI) has completed a study of the performance of balanced residential ventilation systems with heat recovery (HRVs) in Norway.
The use of natural ventilation systems continues to be a popular feature in low energy, sustainable building design.
Findings about sick building syndrome in Sydney’s offices are presented. The aim is to ascertain whether perceptions of sick building syndrome in offices impact on discrete aspects of workplace performance and management.
Economically optimal dimensioning of a counterflow and crossflow heat exchanger for free cooling | 2003 | English
During the cold seasons, it is possible to use ambient air to cool down the coolants in air-conditioning or other refrigeration applications. Applying this free cooling reduces the energy costs of a refrigeration machine.
In the survey study ‘Kantoor 2000’ the HVAC-system of several large office buildings in Flanders was monitored. Some of these buildings use air humidity control, most of them not. This triggered the question : why?
Mold in dwellings is a persisting complaint in moderate climates.
For energy savings, DCV systems are more and more used in ventilation systems. In France, in nonresidential buildings, these systems are generally controlled by either a CO2 sensor, or an opticalmovement detection (infrared).
A Demand Controlled Hybrid Ventilation System is a two-mode system using natural forces as long as possible and electric fans only if necessary.
An experimental campaign was organized during the summer period 2002 in Athens, in the framework of the European RESHYVENT Project.
Natural night ventilation and an earth-to-air heat exchanger are applied in the low-energy office building ‘SD Worx’ in Kortrijk (Belgium).
Infiltration has traditionally been assumed to contribute to the energy load of a building by an amount equal to the product of the infiltration flow rate and the enthalpy difference between inside and outside.
