Simulations of indoor air quality and ventilation impacts of demand controlled ventilation in commercial and institutional buildings | 2003 | English
Carbon-dioxide (CO2) based demand controlled ventilation (DCV) offers the potential for moreenergy efficient building ventilation compared with constant ventilation rates based on designoccupancy.
Ventilation in dutch houses, a study in a representative sample of the dutch housing stock | 2003 | English
The goal of this study was the determination of the existing situation in houses with regard to air quality and energy used for ventilation in relation to the health of inhabitants.
The airflows through a one family prototype building have been simulated. Supply openings in living room and bedrooms have a size of 200 and 400 cm2 respectively.
A concept is investigated for the energy efficient control of residential mechanical ventilation in response to outdoor air temperature and the corresponding stack-driven infiltration.
Residential dehumidification and ventilation systems research for hot-humid climates | 2003 | English
Twenty homes were tested and monitored in Houston, Texas, U.S.A. to evaluate humidity controlperformance and operating cost of six different integrated dehumidification and ventilation systems that could be applied by production homebuilders.
Field characterization of the envelope leakage of houses for determining rehabilitation priorities | 2003 | English
This paper presents the results of a field study conducted on 8 houses (out of a set of 31) owned and managed by a French social housing public leasing company.
IEA ECBCS Annex 36 : Energy Concept Adviser for Technical Retrofit Measures - An internet-based Tool on Information, Assessment and Concept Development of Energy-saving Retrofit Strategies | 2003 | English
Research partners of 10 different countries are developing a computer tool in the framework of IEA ECBCS Annex 36, which helps decision makers to include the most energy-efficient and economic technical retrofit measures into the retrofit of their
Analysis of a ventilated residential building by means of an air based radiative cooling system | 2003 | English
The thermal performance of a monozone building located in Lisbon is studied when night ventilation combined with radiative cooling is used in order to remove the heat from indoors.
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 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
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?
