Build­ing a greener sec­ondary city cen­ter

China Daily (Hong Kong) - - CHINA - By DU JUAN du­juan@chi­nadaily.com.cn

Beijing’s new sub­cen­ter of Tongzhou will be built to the high­est stan­dards and in­cor­po­rate the lat­est ad­vances in science and tech­nol­ogy, ac­cord­ing to one of the cap­i­tal’s top of­fi­cials.

Cai Qi, act­ing mayor of Beijing, made the com­ments dur­ing his first visit to Tongzhou dis­trict af­ter be­ing ap­pointed last month. His tour of the area can be seen as re­flect­ing the im­por­tance of its role in the cap­i­tal’s fu­ture de­vel­op­ment.

To boost the de­vel­op­ment of the cap­i­tal’s new sub­cen­ter and re­lieve some of the traf­fic con­ges­tion and over­crowd­ing in down­town Beijing, the mu­nic­i­pal govern­ment plans to move its ma­jor de­part­ments to Tongzhou by the end of 2017.

The of­fice build­ings that will house these de­part­ments are al­ready un­der con­struc­tion.

What is know as the “pas­sive house” con­cept has been ap­plied to their de­sign, aim­ing to im­prove each build­ing’s en­ergy ef­fi­ciency and reduce its car­bon foot­print.

Ad­vanced tech­nol­ogy will be em­ployed to cut the amount of en­ergy needed for heat­ing and cool­ing these new build­ings, in a move that of­fi­cials hope will help pro­mote the pas­sive house con­cept in China.

Ac­cord­ing to Beijing’s civil build­ing en­ergy-sav­ing plan for the 13th Five-Year-Plan pe­riod (2016-20), the cap­i­tal will be­gin con­struc­tion of more than 300,000 square me­ters of ul­tralow-en­ergy build­ings in the next four years. Tongzhou is set to de­velop such build­ings on a large scale.

It is es­ti­mated that the two govern­ment of­fice build­ings that will in­cor­po­rate the con­cept could use up to 60 per­cent less en­ergy than tra­di­tional de­signs.

In ad­di­tion to sav­ing en­ergy, the In­ter­net Plus strat­egy is also be­ing ap­plied to Tongzhou’s face-lift.

Hes­teel Group, China’s largest pro­ducer of iron and steel, is sup­ply­ing much of the con­struc­tion ma­te­ri­als for the area’s new of­fice build­ings, and has de­vel­oped soft­ware that can pro­vide qual­ity cer­ti­fi­ca­tion through a mo­bile phone app — the first time in the coun­try’s his­tory that such a ser­vice has been com­mer­cially rolled out.

Build­ing in­for­ma­tion tech­nol­ogy is con­stantly mon­i­tor­ing the con­struc­tion sched­ule, cal­cu­lat­ing the time the pro­ject should take based on the al­lo­cated re­sources, cap­i­tal and avail­able la­bor.

If it finds that the pro­ject is be­hind sched­ule, it will au­to­mat­i­cally is­sue a warn­ing to the man­age­ment team. The pro­ject’s lead­ers can then mon­i­tor the con­struc­tion site man­u­ally.
