Increasing emphasis on energy-efficiency has many jurisdictions enacting stricter energy codes.
For energy savings, DCV systems are more and more used in ventilation systems but toestimate their energy savings, variation of occupation in the building (in time and number ofperson) must be estimated.
The building envelope is primarily an environmental separator, which allows indoor spaces to bemaintained at different conditions from the outside environment.
In France, in non residential buildings, these systems are generally controlled by either a CO2 sensor or optical movement detection (infrared).The part of the study we present here was to determine :- laboratory tests methods to assess the perfor
The knowledge of indoor air humidity in the design phase is important to decide on the appropriate moisture control measures to prevent moisture problems in building components.
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
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.
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.
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 use of natural ventilation systems continues to be a popular feature in low energy, sustainable building design.
The Norwegian Building Research Institute (NBI) has completed a study of the performance of balanced residential ventilation systems with heat recovery (HRVs) in Norway.
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?
Over the past decade, there has been extreme media attention to issues about mold and allegedlyadverse effects.
