The heat transfer processes occurring in the earth surrounding a building have a substantial effect on the building's energy consumption.
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.
Today energy saving rates due to retrofits in residential housing are either measured by experiment on site or predicted by system simulation.
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.
At the present time several powerful simulation models exist for the assessment of building environmental performance at the design stage. However when used as design tools these models suffer from several fundamental limitations.
Much research has been directed towards development of software environments that allow easy construction of building simulation models of widely varying structure and purpose. For example, TRNSYS has been in use for a number of years.
This paper describes a design tool, 'Condensation Targeter', for assessing condensation risk in dwellings and the effect of remedial measures thereon.
Recently, the more accurate comparisons between the existing building behaviour and the simulations have shown that a more realistic model of the whole system has to be considered.
Computer simulation/end-use metering or "can we count on energy savings estimates in designing demand-side programs"? | 1989 | English
In 1937, Congress created the Bonneville Power Administration (Bonneville) to serve as transmission and distribution agent for electricity generated by the Bonneville Dam.
