LoginProposed 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.

Perturbations in atmospheric density caused by high rise buildings and their effect on astronomical observations: a case study | 1989 | English
Experimental studies during the 1940S concluded that heat loss from slab-on-grade floors is proportional to floor perimeter length. More recent numerical investigations, however, indicate that area and shape are also important parameters.
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.
How good are single zone - monthly based - correlation methods for building energy and comfort performance assessment | 1989 | English
Several single zone, monthly based, correlation methods have been developed at a national level , ver the past few years.
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.
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
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.
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.
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.
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.
The task is for COMIS to develop a reliable and well running multizone infiltration model on a modular base.
Traditionally, the lighting engineering community has emphasized illuminance, the amount of light reaching a surface, as the primary design goal.
In order to create a simulation model of a building, it is usually necessary to make a number of assumptions and/or approximations about the building being simulated.
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.
