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.
This paper describes a recently developed, multi-chromatic lighting simulation model, known by the acronym DIM (Digital Illumination Model).
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.
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.
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.
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
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.
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.
