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.
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.
Mathematical models of various kinds are important in many disciplines. Unfortunately, it is often difficult and time-consuming to develop models.
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
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.
Commercial building owners and managers face a complex array of HvAc technology options. Economicanalysis of the options requires consideration of technology characteristics, equipment operatingstrategies, and utility rates.
Today, the development of computer makes the accurate performance analysis of complex system by simulation available for most of the research community, and very soon for every concerned engineer.
Building simulation software alone can sometimes fall short of providing a reliable building model.
