Preface

The heat island effect is increasing day by day. However, the high degree of development in cities ignores the impact on the environment. Through environmental simulation and ecological planning, we can reduce the environmental damage caused by buildings, pay more attention to the improvement of the urban environment and the design of future buildings. Propose new ways to improve the ecological impact of future heat islands.

Introduction to UHI

Negative impacts of UHIIntroduction to UHI

Introduce

Urban heat islands are defined as “urban areas with higher temperatures than surrounding rural areas.”This relative popularity is driven by “land use, configuration and design of the built environment. This is the result of heat capture (including street layout and building size, the heat absorption properties of building materials), reduced ventilation, reduced greening and water features, and direct heat emissions from homes and industry."

Impact of UHI

02 Affect Weather

Collateraleffects on local meteorology include changes in local wind patterns,cloud and fog formation, humidityand precipitationrates.

The area affected by UHI thatchanges the climate is 2-4 times larger than the city itself.

Healthy Ecology

Animal

UHI effects have the potentialto directlyaffect the healthand well-beingof urban residents.

High UHI intensityis associated with increasedconcentrations of air pollutantsat night, which can affect air qualitythe next day.

UHI can also harm water quality. Rainwater carries heat from warm pavement and roof surfaces into storm drains and then into streams, rivers, ponds and lakes, raising the water temperature there.

Thermal pollution. This pollution can sometimes increase water temperatures by 11 to 17 C, causing thermal stress and shock to fish inhabiting the water body.

Species thatare good at migratingcan take advantageof the conditions provided by UHI to thrivein cities outside their usual range.

The UHI effect alters thenaturalselection process. Selective pressures such as temporal changes in food, predation,and water are relieved, creating a new set of selective pressures.

Another consequence of the UHI effect is theincrease in energy requirementsfor air conditioningand refrigeration in relatively hot cities.

Improvement plan

Urban commercial building

In highly developed cities, the inherent impact of buildings on nature is ignored, which intensifies the heat island effect.

Combining nature, exploring architectural forms that prioritize the environment, and creating a space where urban dwellers can comfortably and effortlessly enjoy nature.

Base selection

In 1980, the city government announced its main plan. In 1995, the area ratio was increased to 630%, and in recent years, intensive development has continued.

Xinyi Planning Area

Introduction to Xinyi District

Historical axis

Problems such as oversaturation of the population, an old city appearance, and the increasingly developed industrial chain have led to the relocation of Taipei's military base. Taipei's second business district will be developed with reference to Japan's subcity.

Location: Today’s Chiang Kai-shek Memorial Hall

1976 years~1978 years

The commercial areas of Zhongxiao East Road, Renai Road, and Xinyi Road were moved eastward, and Lianqin 44 Arsenal (now Xinyi District)was chosen. 1980

Planning Area

The Xinyi Planning Area is planned as a commercial center, and due to its high level of development, it has become the densest department store area in Taiwan. There are fifteen department store shopping malls in the Xinyi Project Area.

Office Space

The office buildingsin Xinyi Districtare mainly rented out of theWorld TradeCenter and the101 Building,and thereare scattered office buildings in thesurroundingarea.

Number of office buildingsin Xinyi District:11 largeoffice spaces

Educational institution

In addition to Xinyi Elementary School, education in the form of community schools is also promoted around the base.

Zhou Zao has many ways to set up schools in line with international standards. For example, the International Trade Center has HASSE Space School, which uses video-based learning with foreign tutors.

Distribution of Surrounding Green Spaces.

Green Spaces:

Apart from the concentrated green area in Sisi Nan Cun, there are scattered parks around the site. Within the Xinyi Planning Zone, the predominant feature is plaza-style green spaces.

Perennial trend

Wind direction:

The long-term monsoon in Taipei is the northeast monsoon, but due to its geographical location, the wind direction in Xinyi District is mostly easterly. Therefore, in line with Taipei’s wind corridor planning, the wind corridor is designed in the east direction to introduce wind to carry heat.

Summer wind direction simulation

Wind direction simulation:

The summer monsoon winds are from southwest to south, and it can be seen that there is good circulationwithin the base.

Design Principles-Improvement Plan

Design approach

Commercialoffice building in the past

1. Highly developed

2. Maximize usage

3. Lack of planting and other planning

Current commercialbuilding

1. Open space on the ground floor

2. Layeredbuilding separation function

Designing penetrations at lower floors allows wind to penetrate the building better.

Creating an architecturaloasis on the lower floors can more effectively reduce heat dissipation at the ground level.

Design plan:

Through architectural design, the building itself can affect the surrounding environment to improve the heat island effect.

Designing process

Rich functional areas

The site is located at the junction of three districts, surrounded by rich and diverse functions. In the past, there were also rich historical buildings and stories scattered around the base.

Qualitative and quantitative

Revitalize the office space through arts and cultural activities and stimulate surrounding business opportunities.

Continuing the surrounding business district and having more connections with the local area.

In addition to office space such as the World Trade Center, it can also be combined with foreign layouts to improve office styles.

Let more young people or new entrepreneurial groups have office space and have more cooperation with other industries.

with education from nearby school districts, learning can be integrated into daily life

only in school.

Strategies for Mitigating Urban Heat Islands

Reference and Optimized Design

Massing scheme

Wind-blocking facade: By leveraging prevailingwind directions, it addresses wind pressure on the windward side of tall structures, consequently reducing theimpact of wind on lower levels.

Vertical wind corridor: By strategically piercingthrough layers, high-level winds can effectively penetrate, achieving urban heat dissipation.

Ecological platform: Allows people not only to engage in activities on a flat surface but also to access the buildingfrom theoutdoors.

Horizontal circulation:Allows people on lower levels to traverse freely back and forth without being hinderedby buildingrestrictions.

Lower-Level Process Design

Shrink the massing inward by 10 meters to create pedestrian-friendly pathways, achieving a 65% building coverage within the central red area.

Utilizing wind environment simulation to create a pedestrian-friendly lowlevel environmental plan, mitigating discomfort in winter and promoting ventilation during the summer.

Extending through-platforms up to a 15meter vertical wind corridor penetration, creating tiered platforms for easy access for pedestrians to move upwards and outwards of the building.

Upper-Level Process Design

By planning lower levels with reduced building mass, the intensity of low-rise structures is minimized, allowing for concentrated volume allocation upwards.

Through analysis, creating a penetration layer at the 15-meter mark effectively allows for architectural permeability, while also planning penetration layers in high-rise structures to promote a thermally friendly environment.

Combining wind environment analysis with wind field analysis, rotating the upper direction to address summer prevailing winds, and utilizing a large wind-blocking area to counter winter wind directions.

Structural planning

Using the central vertical axis as the primary architectural structure, and supplementing it with dispersed columns around, as an auxiliary concept for the building structure
