Object-oriented programming, equation-based submodels, and system reduction in SPANK | 1989 | English
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.
This paper describes the techniques for validating dynamic thermal models devised by collaborating institutions in the United Kingdom.
This paper describes a recently developed, multi-chromatic lighting simulation model, known by the acronym DIM (Digital Illumination Model).
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.
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.
The present American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) standard 62-1981 "Ventilation for Acceptable Indoor Air Quality" is being revised.
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.
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
Computers are currently used for a large variety of tasks in building design and analysis.
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.
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.
In thermal simulation codes for buildings, aeraulic transfers are computed either with very simplified models (fixed air distribution) or with sophisticated models (based on the computation of the pressure fields).
In order to assess the applicability of a more modular approach to the development of building thermal analysis programs, this paper begins with a review of some of the basic numerical methods used in simulation.
Building energy simulations for design, evaluation, commissioning, control and diagnostics | 1989 | English
The most common use of building energy simulations, by far, is in the design of buildings, especially non-residential ones.
This papers introduces an emulation system for simulation of the thermal process of building and plant named ESAC (Emulation Set for Air-Conditioning systems) developed in 1984, and a prototype system was presented in 1985 (1), since then a great
Mathematical models of various kinds are important in many disciplines. Unfortunately, it is often difficult and time-consuming to develop models.
This paper summarises the objectives and initial achievements of BEPAC, a recently formed club based in the UK which in many respects parallels the stated goals of IBPSA.
