LoginThe objectives of this discussion paper are: to define the new Annex on "Calculation of Energy and Environmental Performance of Buildings"; to determine feasibility of the Annex i.e.
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.
The paper presented is based on work done within the IEA ANNEX 10 'system simulation' group.There, eight research instituts discussed and agreed on simulation models for heating and air conditioning components.
This paper describes the techniques for validating dynamic thermal models devised by collaborating institutions in the United Kingdom.
Several single zone, monthly based, correlation methods have been developed at a national level , ver the past few years.
Lighting energy conservation measures are typically recommended in commercial bui1ding energy audits. Over 60% of the cost in Bonneville Power's commercial building energy conservation programs are related to lighting.
The Indoor Air Quality Simulator for personal computers (IAQPC) has been developed in response to the growing need for quick, accurate predictions of indoor air contamination levels.
Traditionally, the lighting engineering community has emphasized illuminance, the amount of light reaching a surface, as the primary design goal.
Many criticisms have been made about existing software for building energy analysis and simulation. In this paper, we try to show the interest of the model-based approach. The credibility of simulation results is pointed out.
This paper describes a general purpose software, Florida Software for Engineering Calculations (FSEC 1.1), that is capable of solving various transport equations used in building science (e.g., combined heat and moisture transfer, fluid flow, cont
Modellers ands users of simulation softwares need to agree on a standard way to state the physical bases of their models The proposals presented in this paper are not new; they refer to the very classical way of describing thermodynamical systems.
The heat transfer processes occurring in the earth surrounding a building have a substantial effect on the building's energy consumption.
Collaborative efforts among building simulation researchers in Europe and the US have resulted in wide acceptance of certain features as necessary attributes of future simulation environments.
Proposed construction of high rise buildings near the U. S. Naval Observatory in Washington D.C. caused astronomers to ask what effect the heat released by these buildings would have on their ability to make accurate observations.
An index of local thermal comfort and pollutant distributions have been computed with the TEMPEST computer code, in a transient simulation of an air-conditioned enclosure with an incomplete partition.
Computers are currently used for a large variety of tasks in building design and analysis.
Building energy analysis programs have undergone a slow evolution since arrival over a decade ago. The frequency of use and number of applications for these sophisticated modeling tools seems to have reached a plateau.
Lawrence Berkeley Laboratory is developing a PC-based computer tool, the Retrofit Energy Savings Estimation Model (RESEM) which can provide high-quality estimates of energy savings, based on actual pre-and post-retrofit utility bills.
In a typical computer-based building energy management system (BEMS) for HVAC applications, pertinent variables such as pressure, temperature, fluid flow rate, valve and damper positions and the open/close status of the flow control devices, are m
Some details of the optimization work conducted over the last five years in a high rise office complex are described.
Since methods incorporating the time value of money are the only ones that give an accurate picture of life costs of a system, they are the only methods appropriate for the analysis of building lighting systems.
