Integraal ontwerpen nodig bij hybride ventilatie en meer daglicht in gebouwen

Vroeger werden gebouwen natuurlijk geventileerd en daglicht was de voornaamste bron van verlichting. Het binnenklimaat was vooral afhankelijk van het type gevel, dak, thermische massa en lokale verwarming. Overal in de wereld kunnen voorbeelden van traditionele gebouwen worden gevonden met een binnenklimaat waarin mensen zich comfortabel voelen...

The creation of SenseLab: a laboratory for testing and experiencing single and combinations of indoor environmental conditions

Research has shown that staying indoors is not good for our health. People spend more and more of their time indoors. Therefore, providing a healthy and comfortable indoor environment is very important. The SenseLab will contribute to the understanding of and coping with the indoor environment. Students, teachers, researchers, but also the...

A review of comfort, health, and energy use: Understanding daily energy use and wellbeing for the development of a new approach to study comfort

There is a need for reducing dwellings’ energy consumption while maintaining a comfortable and healthy indoor environment. This review was performed to provide a steppingstone for identifying new methods for studying everyday home energy use and comfort. First, an overview of comfort is given as seen from different disciplines, depicting the...

Mogelijkheden van natuurlijke of hybride ventilatie

Wanneer is natuurlijke ventilatie zinvol en wanneer niet? Waarom zijn we in veel gevallen overgegaan naar volledig mechanisch geventileerde gebouwen? Hoeveel ventilatie is eigenlijk nodig? Dit soort vragen zijn niet zo eenvoudig en eenduidig te beantwoorden. Er zijn vele meningen over.

Natuurlijk ventilatie: Hét antwoord op al uw binnenklimaatproblemen?

Dit artikel gaat vooral in op de binnenmilieuaspecten van natuurlijke ventilatie. Wat hebben we de afgelopen jaren geleerd?

Robust Climate Design Combines Energy Efficiency with Occupant Health and Comfort

Often, when designing and operating buildings, the goal is to achieve low energy consumption as well as a healthy and comfortable indoor environment. Studies in the US and The Netherlands show a large discrepancy between the predicted and the actual energy consumption of buildings. Some buildings perform better than predicted, while other...

Thermisch comfort: Historisch overzicht

Thermisch comfort is belangrijk. Voor het ontwerpen van het binnenklimaat, dimensioneren van klimaatinstallaties en beoordelen van het binnenklimaat in de praktijk is een comfortabel en gezond binnenklimaat één van de belangrijkste uitgangspunten. Simulaties van het ontwerp of metingen in praktijksituaties worden getoetst aan comfortcriteria....

Thermisch comfort: Huidige en toekomstige normen

In dit artikel worden de normen en richtlijnen behandeld die op genoemde onderzoeken zijn gebaseerd. Ook wordt onderzocht hoe normen en richtlijnen voor thermisch comfort er in de toekomst uit zouden kunnen zien, waarbij een lager energiegebruik en verbeterd comfort de uitgangspunten zijn.

Comfort Temperatures for the Low-Income Group in a Hot-Humid Climate

The results presented in this paper are part of the doctoral research that is being done at Delft University of Technology, Netherlands. One of the main objectives is to find the level of thermal comfort accepted by people from the low-income group in Surakarta, Indonesia. Personal aspects (gender and clothing index), characteristics of the...

Healthy and comfortable dwellings for the low-income settlements in Surakarta

Technology for the low-income group of people should be as simple as their daily life. Giving recommendations for simple dwelling design and changing people’s behaviour for a better living are the concerns of this research. A field-survey was conducted in November-December 2010 involving 426 respondents from four low-income kampongs in Surakarta...

Adaptive principles for thermal comfort in dwellings: From comfort temperatures to avoiding discomfort

Many theories on thermal comfort exist and there are many ways to deliver this in an energy efficient way. Both aspects are often studied in a static way and most of these studies only regard one of the aspects, seldom investigating what influence the way of delivering thermal comfort has on the actual perceived thermal comfort. This paper...

Thermal comfort in the different settings of low-income dwellings in Surakarta, Indonesia

As a preparation to develop guidelines and design principles for better dwellings in the tropics, a pilot survey was conducted to get data of the current situation of thermal comfort in the dwellings of low-income people in Surakarta, Central Java - Indonesia. These improper dwellings which locate nearby the rivers have ever been hit by big...
