LoginThe paper describes a system solution developed in Sweden for domestic buildings with pre-cast concrete units where the floor consists of a 0,06 meter thick concrete slab with a framework casted into the slab and a beam.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
A question raised about displacement ventilation, is whether floor heating can be utilised without disturbing the thermal stratification in the room.
Even though simulation is being increasingly used in design of modern buildings, the full potential of simulation is usually not achieved.
Even in cold climates, offices normally need to be cooled due to the internal heat loads from people, equipment and lighting. Either a chilled ceiling or chilled beams with cooled water as medium or chilled air can be used.
This paper shows that well proved state-of-the-art technology can be utilized to keep annual average energy consumption in office buildings below 130 kWh/m2, which is well below today's average, without compromising any major functional or ar
This paper shows that it is possible to calculate the optimal outdoor air rate at different outdoor temperatures in the economiser cycle.
In low energy dwellings the ventilation heat losses are significant. Reduction of these heat losses can be achieved by introducing demand controlled ventilation i.e. ventilation rates are set below normal level when rooms are no longer occupied.
The CEN TC 156 / WG2 (ventilation for residential buildings) has prepared a new European draft for the test method of Heat Recovery Units (prEN 13141-7). This method should ensure a common way of testing these units all over Europe.
Using performance characteristics of balanced ventilation units tested in laboratory of CETIAT, a complete ventilation system in an individual house is modelised, in details.
The authors have proposed a system for stabilizing air temperature using direct heat exchange between granulated phase change materials (PCM) and air.
In summer, most areas in Japan are hot and humid. Hokkaido Island, which is the most northern part of Japan, is the only exception.
DEVELOPMENT OF A PCM AIR FILTER AND ITS APPLICATION TO A CONSTANT The authors have developed a PCM air filter which stabilizes the temperature of air passing though it.
This paper intends to answer the folllowing question : Why a laboratory on Indoor Air technology ?Some good reasons are that the HVAC sector in Norway is facing an increasingly difficult situation :.
The mixing of different air streams is a process commonly found in air handling systems. One of the most common examples of this process is found in the air handling unit mixing box where outdoor air is mixed with return air.
Today the use of energy efficient technology and renewable energy sources have not become mainstream in the building industry. One of the main reasons for this is thought to be that each part in the building is considered separately.
In this paper, a CFD analysis of airflow and contaminant distribution within enclosed vehicular parking facilities is presented. First, the CFD simulation is validated using field data.
The conventional constant air volume exhaust fan system is actually a variable air volume system. The fan airflow increases as the fume hood airflow decreases.
The interior zone and exterior zone air-handling units (AHU) can be connected through their return air ducts to become a new air-handling unit system, named OAHU system, which allows optimal choice of outside air intake and decouples sensible and
Residential distribution systems are inherently inefficient at delivering heated or cooled air to the conditioned space as the result of poor design and installation practices.
Past research that has evaluated the association between student performance and some change variable (building renovation, room temperature, curriculum, teacher involvement, etc.) has focused on student-level data and has not adequately accounted
