这是一项国际任务，也是一项道德和经济上的义务，以设计能源使用适度的系统。尽管美国缺乏明确的国家能源政策，
地方和区域能源规范为暖通空调系统设计师提供了一些指导。这些规范鼓励建筑施工
具有较低固有能量要求的照明系统
其从更少的瓦特和空气处理中获得更多的照明
使用较少的风扇、泵和
压缩机功率。这些代码大多基于美国
供暖、制冷和空调工程师学会
（ASHRAE）标准90.1。
在许多暖通空调设计涉及翻修和
旧建筑和系统的改造，有很好的机会
替换组件和系统概念，将提供：
通过使用较少的能量而获得类似或改善的舒适性。因此，我们建议
新建和改造建筑中的五个节能T：

2.小声点！如果必须运行，则将其设计为在低级别运行
其仍将满足职责。尝试提供调制控制
对于所有能源消耗者。
3.调整一下！操作员：保持设备处于良好的运行状态。
设计人员：可靠性和可维护性设计。
4.转身！对于改装设计师：如果您找到一个系统
消耗过多的能量，改进它。
5.把它扔掉！如果一个系统是一个能源消耗者，并且不放贷
自己去康复，愿意把它拿出来。改造设计

一句警告的话。节能在暖通空调设计中很重要，但不是暖通空调系统的目的或功能。暖通空调
系统旨在提供舒适或受控环境。

anic fuels can be estimated in total volume, with less this year than
there was last. There is a finite limit to the potential development of
renewable energies, all derived from the sun, such as wood, wind, hydropower, etc. In terms of magnitude, nuclear power (the fusion concept, at that) is the only known energy source that offers hope of being
able to industrialize the third world and to sustain a growing world
population over centuries rather than decades. Yet the use of nuclear
power is mired in political quicksand in the United States.
The conclusion for the designer of HVAC systems, all of which by
definition are energy-managing and energy-consuming, is that there

is an international mandate as well as a moral and economic imperative to design systems which are modest in their use of energy. Although the United States lacks a well-defined national energy policy,
local and regional energy codes give some direction to the HVAC systems designer. These codes encourage the construction of buildings
which have lower inherent energy requirements, lighting systems
which derive more illumination from fewer watts, and air-handling
systems which move more air and water with less fan, pump, and
compressor power. Most of these codes are based on the American
Society of Heating, Refrigerating, and Air-Conditioning Engineers
(ASHRAE) Standard 90.1.
In a time when much HVAC design involves the renovation and
retrofit of older buildings and systems, there is good opportunity for
substitution of components and system concepts which will provide
similar or improved comfort by using less energy. Thus we suggest the
five T’s of energy conservation in both new and retrofit construction:
1. Turn it off ! There is no substitute for the off switch. Provide a
mechanism to turn off energy-using systems when they are not
needed.
2. Turn it down! If it has to run, design it to run at the lowest level
which will still meet the duty. Try to provide modulating control
for all energy consumers.
3. Tune it up! To operators: Keep things in good operating condition.
To designers: Design for reliability and for maintainability.
4. Turn it around! For retrofit designers: If you find a system which
consumes disproportionate amounts of energy, improve it.
5. Throw it away! If a system is an energy hog and does not lend
itself to rehabilitation, be willing to take it out. The retrofit design
market for the year 2000 on into the next decades is a major industry market.
One good thing about energy conservation is that it nearly always
pays for itself. But sometimes a bit of teaching and long-term vision
are needed to get the message to the person controlling the purse
strings.
A word of caution. Energy conservation is important in HVAC design, but it is not the purpose or function of the HVAC system. HVAC
systems are intended to provide comfort, or a controlled environment.
If we conserve energy to the point that we lose sight of the system’s
function, then we have failed in our duty. There is no glory in owning
a building that drives tenants away with its energy-conserving but
uncomfortable HVAC systems. Nor is there gratitude to an energy
manager in an electronics plant where the production yield drops for
