Climb a Hill

<正>This Saturday,I am going to climb a hill with my classmates.What should I wear?I am thinking about it.I can wear my jeans and trainers because they are fit for climbing a hill.It will be hot in the afternoon that day,so I want to wear a silk shirt.And it will be cool in the morning,so I am going to take my jacket with me.It can make me feel warm.I will enjoy myself in the mountain.     

Ride to School

<正>I think going to school by bike is good for us.First of all,riding to school is a wonderful way to exercise and it's good for our health.Second,it's fun to ride together with friends every day.What's more,if we ride bikes,our parents won't have to drive us to school.There will be fewer cars on the roads.Less driving helps to make our city cleaner.I hope

Thermal performance of different planting substrates and irrigation frequencies in extensive tropical rooftop greeneries

The need for the better use of scarce planetary resources has never been more evident than it is today. However, this need is poorly reflected in human housing. In recent years, there has been a growing realization of the importance of constructing human shelters that better conserve energy and water through appropriate insulation and architectural designs. Among the important advancements in these areas is the use of rooftop greeneries for both energy and water conservation. This paper performs an investigation into this topic within the specific climatic context of tropical regions. Long-term experimental results are provided from a four-floor building in Kaohsiung in the southern part of Taiwan. The study involves a fully monitored extensive rooftop greenery and examines four different plant substrates, three different irrigation regimes, and different types of drought-enduring plants to find the most efficient combination of all three in providing maximum heat insulation and water usage efficiency. The attenuation of solar radiation through the vegetation layer is evaluated, as well as the thermal insulation performance of the rooftop greenery structure. Among the substrates, burned sludge has the best thermal reduction percentage of heat amplitude under the roof slab surface (up to 84.4%). Irrigation twice a week has the best thermal reduction percentage of heat amplitude (91.6%). Among the plant types, Sansevieria trifasciata cv. Laurentii Compacta and Rhoeo spathaceo cv. Compacta are found to be suitable for extensive rooftop greeneries because they have the best coverage ratio and are most drought enduring.

The rooftop shading system of the Humanities Building at SCUT

Rooftop shading is an effective green building design strategy in subtropical areas; it can create an ecological rooftop space and produce energy savings for rooms on the top floor. This article describes the rooftop shading system of the Humanities Building at SCUT (South China University of Technology). A shading calculation software developed by the Building Energy Efficiency Laboratory (BEEL) of SCUT is used to calculate and analyze the rooftop shading effect in summer and winter. The actual performance of this rooftop shading system was evaluated by measuring the wet bulb globe temperature (WBGT) in the shaded and unshaded areas under the shading system on July 2, 2003.
