PRIORITY
Chongqing has a monsoon-influenced humid subtropical cli-
mate, and for most of the year experiences very humid conditions.
Its summers are the hottest and most humid in China.
Chongqing receives abundant rainfall, averaging about
1000 to 1400mm annually. The annual average temperature is
18C to 20C with a low temperature of 4C in winter and high tem-
perature of 40C in summer.
重庆地处亚热带，全年天气比较炎热，尤其是夏天，重庆是
中国最热的城市之一。
-重庆雨量丰富，全年降雨1000-1400毫米，年平均气温在
18-20度之间，冬季最低温度4度，夏季最高气温40度以上。
The buildings main axis runs from east to west, leaving a 170m
facade exposed to south. During summer, the south facade will be the
resposible for the over heating of the building, so we should pay the
most attention to it. Also the north facade will play an important role on
the buildings interior temperature regulation. A further study will be nee-
ded to adopt temperature regulation measurements.
建筑主轴为东西向，右170米长度的立面朝南，因此在整个夏
天南立面对整个建筑冷暖影响非常大，因此我们需要着重考虑它。
当然北立面对整个建筑的冷暖也很重要，深入研究将对建筑冷暖设
计及建设提供很好地依据。0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

SOLAR GAIN防晒
SHADOWS STUDY 阴影研究
As we can see from the shadow diagram of the south
facade, Tower 1 and Tower 2 would cause significant shadows
during summer, therefore the sun irradiance of the south facade
would be less significant and thermal gain would be less important
in certain spots.
It will be interesting to adapt the location of the vertical lo-
uvers of the facade, depending on a detailed shadow study.
正如我们可以从南立面的阴影图看，塔楼1和塔楼2会在夏季
产生显著的阴影效果，因此，南立面的太阳辐照度会少较少，有些
区域获得阳光照射将更少，通过阴影研究可以知道哪些地方设置垂
直百业窗，而有些地方无需设置。
TOWERS-SHADOW DIAGRAM
SUN PROTECTION STRATEGY 防晒策略
The main strategy to protect the building from the sun´s irradian-
ce, is the shape itself. Thanks to the over hanging of the slabs in the
south facade, the thermal gain in summer can be decreased considera-
bly. The secondary sun protection strategy will be vertical louvers scate-
red throughout the building. For a more efficient design of the location of
the vertical louvers, a further study will be needed.
The glass roof areas are the most sensible part of the building
and therefore a sun protection system should be considered.
Solar photovoltaic panels could serve both as an active and passive stra-
tegy. On one hand they produce energy while serving as passive solar
protection system avoiding much of the thermal gains due to solar radia-
tion.This passive measure may involve savings of around 10%.
主要的策略是保护建筑物免受阳光直射。一级防晒体系是建筑本身
南立面的挑出阳台，在夏天可以减小阳光直射。二级防晒体系是分布在立
面的垂直百叶窗。为了使防晒效果更有效，进一步的深入研究是非常必要
的。
玻璃屋顶区域是建筑防晒的敏感部位，防晒系统应重点予以考虑。
太阳能光伏板可以同时做为主动和被动策略来进行实施。一方面他们可以
主动地产生电能，同时作为被动式太阳能保护系统可以削减太阳辐射约10
％。

SUPER INSULATION超级绝热
THERMAL BRIDGING 热传导
A thermal bridge is created when materials with different
insulation characteristics come in contact, allowing heat to flow
through the path created.When calculating heat loss, variations
between as-designed and as-buit can be significant. Thats why the
design needs to ensure the likelihood of such errors occuring are
minimised.
The buildings design should follow a few basic rules that
will help prevent such thermal bridges;
- Do not interrupt the thermal envelope
-When interrupting the thermal envelope, thermal resistan-
ce in the insulation plane should be as high as possible
-At building junctions, insulating layers should meet without
any gaps
-Edges should have obtuse angles.
Inner cladding with plasterboard and thermal insulation
should be used.
As the envelope is composed predominantly of glass, this
glass should have solar control and reinforced thermal insulation
(ATR) in order to decrease the input radiation in summer and pre-
vent heat loss in winter.
Regardless of the chosen glass composition, a system of
aluminum profiles with thermal break should be installed.
当不同温度的材料进行接触时热传导就形成了，热量可经过热传导
损耗，不同材质的物体的热传导性能也不一样，我们需通过计算并通过设
计和建造来减少热传导的发生。
建筑设计应遵循的几个基本规则，这将有助于防止这种热传导;
- 不要打断热量包
- 当热量包被打断时，应选用绝热性能好的材料。
- 在建造时连接处时，绝热层应致密无间隙
- 边缘采用钝角。
内包层与石膏板和隔热性能好的材料。
作为主要由玻璃构成的热量包，该玻璃应具有阳光控制和绝热的性能以减
少在夏季的太阳辐射的进入和冬季热量的损失。
无论选择何种玻璃组件，都应用隔热铝合金型材进行安装。

SUPER INSULATION超级绝热
DOUBLE SKIN 双层隔热面层
Certain parts of the building are highly sensible to heat
exchange.Due to the nature of the materials used and the orien-
tation, this parts of the building will loose high amount of energy in
winter and gain it in summer.The most sensible areas will be the
roof glass boxes.
To tackle this energy problem, we recomend the use of a
double facade skin for the glass boxes. The advantage of a do-
uble-wall system is as follows;
-Outstanding thermal insulation
-Optimal use of energy gains
-Natural ventilation in different weather conditions
-Very good sound protection
-integration of building technology
建筑的某些部分由于材料的关系是非常容易与室外产生热交
换，这样在冬季容易失去热量而在夏季却吸收很多热量而造成能量
损耗，尤其容易产生热交换的是屋顶玻璃屋。
为了解决此能源问题，我们强烈建议使用双层真空钢化玻
璃。同时也建议使用双层墙体，这样做有一下优点：
- 杰出的隔热效果
- 最好的能源利用效能
- 在不同的天气条件下可以自然通风
- 很好的隔音效果
- 能与建筑有机整合

AIRTIGHTNESS / VENTILATION自然通风
INSULATION SKIN
Airtightness is simply the control of airflow within a building.
This means there is no unexpected air leakage; losing warm air or
cold air infiltration.Is very important during design and construction
of the building to make it airtight.
This will have many benefits, some of them include;
-Rediced heat loss
-Reduced energy costs(space heating)
-Improved thermal performance of the structure
-Improved thermal confort.
There will be 2 levels of airtightness required in the building.
Level 1 for the private comercial areas, and Level 2 for the public
spaces. In the Level 1 spaces, the insulation should be better sin-
ce the private spaces require higher airtightness. The public areas
will be designed like outside open spaces, so the airtighness is not
so important.
The airtightness requierments for Level 1 areas will be
achieved by designing a highly insulated skin, as well as double
door entrance into the private spaces.
气密性是防止建筑物空调系统产生的冷气和暖气的意外流
失，因此设计建造中使建筑保持良好的气密性非常重要。这将带来
很多益处，其中一些包括：
- 减少热损失
- 降低能耗支出
- 良好的结构性能
- 良好的温度舒适度
此建筑将有2级的气密性要求。 1级为私人店铺，2级的公共
空间。1级空间的气密性要求和隔热要求是较高的。而公共区域的设
计将会更像开放空间，所以气密性就没那么重要。 1级区域将通过
设计一个高度隔离面层，并配以双门入口来达到气密要求。

AIRTIGHTNESS / VENTILATION自然通风
NATURAL VENTILATION STRATEGY
Natural ventilation has become an increasingly attractive
method for reducing energy use and cost and for providing ac-
ceptable indoor environmental quality and maintaining a healthy,
confortable and productive indor climate rather than the more
prevailing approach of using mechanical ventilation.
In favorable climates and building types, natural ventilation
can be used as an alternative to air-conditioning plants, saving
10%-30% of total energy consumption.
Design recomendations;
-Each room should have 2 separate supply and
exhaust openings. Locate exhaust high above inlet to maximize
stack efect
-Orient windows across the room and offset each
other to maximize mixing within the room
-Windows should be operable by the occupants
-Provide ridge vents
-Allow for adequate internal airflow
-Provide attic ventilations
-Ceiling and whole-building fans can provide effecti-
ve temperature drop at one tenth the electrical energy consump-
tion of mechanical air-conditioning systems.
A natural ventilation system using free-cooling can be easily
implemented and it’s compatible with the HVAC system.
THE BUILDING / BUOYANCY-DRIVEN VENTILATION
Part of the ventilation strategy is to make the building flexible to
the exterior conditions. Is highly recomendable to have operable ope-
nings managed by the building ocupants. This way during the different
seasons, the buildings ventilation will change and adapt to obtain the
most confortable conditions.
During summer season the building will open itself to allow a
higher air flow. Due to differences in air density of interior and exterior,
an upward air stream will rise up through the buildings logias, creating a
chimeney effect that will help renovate the buildings air volume.
The advantages of a Buoyancy-driven ventilation are:
-It doesnt rely on wind; can take place on still, hot summers
-Stable air flow
-Greater control in choosing areas of air intake
-Sustainable method

THE PARKING / NATURAL VENTILATION
The parking area will be around 50,000sqm, which means it
will be necessary a great amount of ventilation machinery to cons-
tantly renovate the air volume.
The most sustainable way to avoid installing all this air-
renovation machines will be to naturally ventilate the parking. It will
be interesting to follow the original landscape-morphology idea,
and introduce some holes and conexions into the parking. Also
trees could be planted inside the parking to introduce some green
feeling.
停车场/自然通风装置
停车区大约50,000平方米，这意味着需要大量的通风机器设备。最
环保的方式是取消大量的机器空气通风装置，而采用自然通风系统。 利
用景观地形理念，通过一些孔洞把新鲜空气引入停车场，也可以在停车场
内种植一些增添绿意。

GROUND LOOP HEAT EXCHANGER
GEOTHERMAL ENERGY
Geothermal heat pumps are systems that use the ground,
groundwater or surface water as a heat source. The ground loop
is a system of pipes that is burried in the gorund near the building.
A fluid circulates through the ground loop to absorb or relinquish
heat within the ground. In the winter, the heat pump removes the
heat from the fluid in the pipe, concentrates it, and transfers it to
the building. The process is reversed during the summer. The air
delivery system uses conventional ductwork or pipe systems to
distribute the heated or cooled air through the building.
A facility with geothermal power generation system (hot and
cold) with high efficiency could covers 30% of the cooling demand
and 88% of the heating demand but itself.
The exact consumption reduction due to geothermal de-
pends on many factors such as the type and use of the building,
the weather, the size, or the installation, but the savings can hover
around 40-60 % compared to traditional pump system heat ex-
change with the environment.
In addition to the ground loop exchanger (or geothermal
exchanger) a high efficiency heat pump can be added in order to
cover the rest of the cooling and heating demand.
地源热泵是使用地面，地下水或地表水作为热源的系统。接
地回路是安置在大楼附近的地下管道系统。流体循环通过接地环路
在地下吸收或释放的热量。在冬季，热泵通过管道和流体把热量带
到建筑物中。在夏季通过管道和流体把热量带入地下。空气输送系
统采用传统的管道或管道系统，在建筑中加热或冷却空气。
地热冷热系统可以满足30％建筑制冷需求和88％的供暖需求。
精确的能效数据取决于多种因素，如建筑物的类型和用途、天气、
设备的大小和安装水平，但可以比传统空调系统节省40-60％ 的能
耗。
除了接地回路热交换器（或地热交换装置）高效率热泵的使
用可以更好地满足建筑的加热和制冷的需求。

latitude of 29 ° and considering a maximum of 20% of total losses
(orientation, inclination and shading), we can estimate the PV
system consumption that consists of aproximate 4000 m2 of PV
panels on the roof of the building to produce between 1000-1500
kWh/m2 per year.
The facility will serve to power the geothermal system, as
well as part of the lighting and air conditioning.

LIGHTING STRATEGY照明策略
LIGHT 照明
Lighting represents about 30% of energy consumption of
buildings. For this reason it is necessary to give the building an
efficient lighting control system that divides the building into zo-
nes, each with its own control system. All circuits must have their
own independent programming start and stop depending on the
volume occupancy of the different stores. The mall must also have
motion detectors and light intensity measuring to adjust the lighting
intensity to the needs of the moment. Efficient provides a saving
of between 10% and 20% of electricity consumption per year with
this system over traditional systems.
For the interior common areas an interesting option would
be systems that redirect natural light from outside inward focusing
it through adjustable reflective mirrors called heliostats. With this
amount of natural light during the day hours, savings of up to 70%
in electricity consumption for lighting can be achieved.
照明约占建筑能耗的30％，因此，有必要给予建筑设计高效
的照明控制系统。我们可以把建筑划分成各个区域，每个区域都有
它自己的控制系统。不同的店铺有不同的独立编程的开关控制系
统。商场还必须具有运动感应器和光线强度测量仪用来根据光线强
度需要来调整灯光强度。这样可以节约10—20%的电能。
对于室内公共区域可以通过系统引入自然光，这个系统称为
定日镜系统。在白天，使用这个系统可以节省照明用电高达70％。
