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.
This paper describes a recently developed, multi-chromatic lighting simulation model, known by the acronym DIM (Digital Illumination Model).
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.
Discussion paper on IEA annex XXI calculation of energy and environmental performance of buildings | 1989 | English
The 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.
Model-based computer modelling: an approach for building energy simulation improvement | 1989 | English
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.
The present American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) standard 62-1981 "Ventilation for Acceptable Indoor Air Quality" is being revised.
Computers are currently used for a large variety of tasks in building design and analysis.
A new computer program has been written for comparing the annual energy and economic performances of different window systems in non-residential buildings.
Development of a component program library for building energy simulation: a japanese experience | 1989 | English
This paper describes the concept of developing a component program library for building energy simulation and the current state of its development, which has been made by a working group of theSociety of Heating, Air-Conditioning and Sanitary Engi
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.
The analysis of enthalpy control strategies and its application in hot and humid climates | 1989 | English
Air enthalpy control strategy, or often known as free cooling, has been very effective in conserving building air-conditioning power consumptions-in moderate climatic areas.
Perturbations in atmospheric density caused by high rise buildings and their effect on astronomical observations: a case study | 1989 | English
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.
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.
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.
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.
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.
