COMBINE is a file utility program developed by Jeff Hirsch of Lawrence Berkeley Laboratories for use with the DOE2.1C building energy simulation program.
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.
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
Modelling heat, moisture and contaminant transport in buildings: toward a new generation software | 1989 | English
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
Over the past 5 years, Dubin-Bloome Associates (DBA) and Ross & Baruzzini, Inc. (R&B) have jointly been working on a project to determine the relationship of the air conditioning load caused by building lighting with time.
Development of a methodology to evaluate the energy and comfort performance of fenestration | 1989 | English
This paper describes the development of a new concept for analyzing the performance of fenestration systems.
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.
Traditionally, the lighting engineering community has emphasized illuminance, the amount of light reaching a surface, as the primary design goal.
The task is for COMIS to develop a reliable and well running multizone infiltration model on a modular base.
The availability of daylight, including diffused sky light and direct sunlight, in urban open spaces is an important environmental factor in designing and regulating buildings in high density urban areas.
Predictions of thermal comfort and pollutan distributions for a thermostatically-controlled, air-conditioned, partitioned room: numerical results and enhanced graphical presentation | 1989 | English
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.
Today energy saving rates due to retrofits in residential housing are either measured by experiment on site or predicted by system simulation.
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.
Techiniques for simultaneous simulation of buildings and mechanical systems in heat balance based energy analysis programs | 1989 | English
The current generation of building simulation software is based upon separate building and mechanical system simulations.
Object-oriented programming, equation-based submodels, and system reduction in SPANK | 1989 | English
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.
This paper describes results from a larger project [1] which investigated the sizing of Thermal EnergyStorage (TES) systems used as part of the cooling system in buildings.
This paper describes the techniques for validating dynamic thermal models devised by collaborating institutions in the United Kingdom.
Simulation and optimization in the real time control of building environmental systems | 1989 | English
Some details of the optimization work conducted over the last five years in a high rise office complex are described.
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.
