Abstract: This paper describes a decision-support framework assisting the design of nonresidential buildings with natural ventilation.The framework is composed of decision modules with input, analysis algorithms and output of natural ventilation design. The framework covers ventilation with natural driving force and mechanical-assisted ventilation. The proposed framework has two major assessment levels: feasibility assessment and comparison of alternative natural ventilation approaches. The feasibility assessment modules assess the potential of the site with the design proposition for natural ventilation in terms of wind, temperature, humidity, noise, and pollution conditions. All of the possible natural ventilation approaches and system designs are assessed by first applying constraint functions to each of the alternatives. Then the comparison of alternative approaches to natural ventilation continues by assessing the critical performance mandates that include energy savings, thermal comfort, acoustic control, indoor air quality, and cost. Approaches are finally ranked based on their performance.13962
Introduction
As a design strategy, when properly understood and applied, natu-
ral ventilation can significantly reduce building energy consump-
tion while ensuring both good indoor air quality IAQ and
thermal comfort conditions. Natural ventilation as a design and
operating strategy may be effective in many climate zones in the
United States Chen 2004; Jones and West 2001. Unfortunately,
natural ventilation is currently underutilized in nonresidential
buildings. The paper represents a first step toward developing a
decision-support framework and therefore reader feedback is en-
couraged through the writer contact given at the end of the paper.
When and how to integrate natural ventilation approaches into
nonresidential buildings are not well known. To be most effective,
the design of naturally ventilated buildings must begin early in 源自六`维`论^文-网.加7位QQ3249^114 www.lwfree.cn
the design process such as choosing and analyzing the site leading
to the assessment of the performance of alternative approaches.
The decisions related to this process must take into account both
technical and architectural goals, as well as understanding of per-
formance issues such as energy savings, thermal comfort, sound
transmission, security, indoor air quality, and cost.
This paper identifies critical issues and proposes assessment
approaches with the inputs, analysis algorithms and outputs for a
decision-support structure for natural ventilation of nonresidentialbuildings. The framework focuses on the early design stages and
covers ventilation with natural driving forces and mechanical-
assisted ventilation. The goal is that through the development of
this framework designers can be better informed of the decision-
making process for natural ventilation and a computer-based tool
is being developed to assist the process. The tool is planned to be
completed one year after the framework is ready. It is developed
on Windows platform with a user-friendly interface and will be
used in the early design phases.
Due to space limitations a full discussion of the structure is not
possible here although it will be available as a more complete
document. The overall structure and issues are presented.
Framework Overview
The decision-support framework is developed from three main
concerns: 1 the necessary inputs; 2 assessment procedures;
and 3 structure of the outputs. The inputs were determined by
identifying the critical issues of design when integration of natu-
ral ventilation is a goal. The critical issues were identified from
literature review and case studies of exemplars as well as inter-
views with architects and engineers with experience in design of
buildings for natural ventilation. The framework addresses both 中央空调建筑自然通风设计英文文献和中文翻译:http://www.lwfree.cn/fanyi/20170929/14350.html
