regarding the role and importance of subsurface drainage in water table control, many studies have been made throughout the world to find out new techniques and more economical solutions, especially as related to different pipe envelope material and their installations. this research was conducted to investigate the use of rice husk, as drain envelope material, in drainage installations. in add...

This study aims to propose building envelope retrofit packages for existing naturally ventilated school buildings in the hot–humid climatic region of Chennai, India. Indoor thermal parameters were collected through field studies from nine sample classrooms a selected May 2019, between 9.00 am and 4.00 pm. The performance assessment was performed by examining discomfort hours using CBE comfort t...

Building envelope optimization always occupies an important place in sustainable building design. This paper selects a large-scale space as research object, which requires more complex and flexible fenestration system. On the premise of complying with some rules, the fenestration is easily managed by adjusting the number and position of small rectangular patches on the grid-based exposed surfac...

The aim of this paper is to optimize the building shape parameters and envelope parameters influencing the rural building energy consumption in cold winter and hot summer climate. Several typical models are established and optimized by integrated TRNSYS and GenOpt. Single-objective optimization has provided guidance to the multi-dimensional optimization. Building shape and envelope parameters a...

In order to study the fresh air load characteristics of low energy consumption buildings with different envelope structure parameters, combined law load, saving measures were studied. Taking ultra-low building Shenyang Jianzhu University as an example, DeST simulation software was used establish five groups models parameters for simulation. The results show that heat in model 1 5 is 29.89%, 34....
