Thermal comfort for naturally ventilated houses in Indonesia

This paper presents an extensive field survey conducted in residential naturally ventilated buildings in Indonesia. The data gathered has been analyzed and revealed that the Predicted Mean Vote equation predicted a warmer thermal perception compared to what people really felt. Under hot and humid tropical climate, people in free-running buildings had a preference for cooler environment and for higher wind speed.

Contribution of indoor exposed massive wood to a good indoor climate : in situ measurement campaign

The aim of the study is to evaluate the possibility of ensuring an indoor climate within an acceptable range thanks to the use of large exposed massive wood surfaces. The description of the experimental study performed in four occupied flats of a multi-storey residential building in Sweden is made in this paper along .The analysis of the in-situ recordings is presented too.

Indoor Air Effects on Health in Dwellings Occupied all Daylong by Elderly

A recent survey study suggested that elderly people’s lifestyle and building + dwellings factors exposed them to an uncomfortable and poor environment regarding indoor air quality. In order to confirm the qualitative statements of this study, measurements

Ventilation and indoor air quality in new homes

The aim of that study is to produce guidance in adequate ventilation in new domestic buildings. The paper gives a description of the development and application of a method for measuring the mean ventilation rate in occupied homes with the measurement of indoor air pollutants. Results are presented.

THADE Project: guidelines and standards on indoor air quality in dwellings

This paper is the presentation of the authors'work in the THADE project. Their objective has been to review legislation and guidelines on air pollution and air quality in European dwellings and outside Europe too.

Survey on minimum ventilation rate of residential building in fifteen countries

The Minimum Ventilation Rate standard for dwellings is essential not only to provide occupant health and comfort, but also to remove and dilute the dominant pollutants. The purpose of this survey is to clarify and compare the regulations, standards or guidelines of ventilation requirements for residential buildings of various countries. The studies are based on the many literatures and interviews with the specialists in building regulation.

Introduction to integration of renewable energy in demand controlled hybrid ventilation systems for residential buildings

In the scope of the EU supported project RESHYVENT, the possible integration of Renewable Energy Solutions (RES) into hybrid ventilation systems has been analysed. The focus has been on solar and wind applications to substitute the use of fossil fuel. The feasibility of the investigated options depends on the ventilation concept the RES is integrated into, the location of the building geographically, placement of the RES in the building and on the urban environment.

Solutions for MVHR in existing dwellings

For retrofitting of existing dwellings MVHR is seldom applied, despite the potential in energy saving and improving thermal comfort and indoor air quality. Major barriers and limitations for application are lack of space, especially for the supply ducts and the MVHR units as well as the complexity of execution. Also initial costs are an important barrier. Limiting supply ducts could be beneficial for application in single family dwellings. In a study some configurations with simplified air supply with MVHR in single family dwellings have been investigated.

Setting up a database of indoor climate measurements in recently built Belgian dwellings

One of the major sources of problems in dwellings -if not the main source- is moisture, especially due to surface and interstitial condensation on walls and roofs. For this reason, it seems important to evaluate the current standardisation and reference documents dealing with moisture and eventually to develop new assessment methods. This is the goal of the Belgian project "Moisture problems in roofs", carried out by BBRI, KUL, RUG and W&K. The first step is to collect a large number of indoor climate measurements in recently built dwellings built.

Natural ventilation of residential buildings in protuguese winter climatic conditions

In this paper, the current situation of Portuguese residential buildings in terms of ventilation systems ispresented. The indoor air renewal is, normally, obtained by providing fresh air exclusively by air leakage of doors and windows and their occasional opening and exhausting the air through ducts placed in kitchens and bathrooms. A recent revision of the Portuguese standard NP 1037-1, concerning natural ventilation of dwellings, is studied and its influence upon heating energy consumption and indoor temperatures is reported.
