// Description
The nearly zero energy building (NZEB) at the China Academy o f Building Research (CABR) adhered to the design principle
o f "passive building, pro active o ptimizatio n, eco no mic and pragmatic". An ambitio us annual energy co nsumptio n go al o f 25
kWh/(m².a) (including heating, co o ling and lighting energy) was set during the design phase witho ut co mpro mise o f building
functio n and indo o r enviro nment quality. The demo nstratio n pro ject integrated best available building energy co nservatio n
techno lo gies, striving to build a signature NZEB pro ject and establishing fo undatio n fo r develo pment o f China’s NZEB
standard.

Co ntractant général
Dé m arche dé ve lo ppe m e nt durable du m aît re d'o uvrage : the first nearly zero energy building in China, designed and
built under the umbrealla o f US-China Clean Energy Research Center Pro gram. With the go al o f annual heating, co o ling and
lighting energy under 25KWH/m2.
De script io n archit e ct urale : The main techno lo gies emplo yed include the Vacuum Insulatio n Panel (VIP) building
insulatio n system, Lo w-e vacuum glazing with inter-pane mo to rized lo uvered shading system, gro und so urce heat pumps,
medium and high temperature so lar co llecto r, energy reco very system, liquid desiccant ventilatio n system, high efficiency
luminaries and advanced lighting co ntro l, energy management system and building auto matio n system, nearly zero energy

This pro ject ado pted high perfo rmance building envelo pe system to reduce its energy demand. Undergro und bo reho le and
so lar co llecto rs serves the geo thermal heat pumps and abso rptio n chiller as the primary co o ling and heating so urces.
Thro ugh smart use o f renewable and traditio nal energy, building heating demand in winter is to be met with zero use o f fo ssil
fuel and co o ling energy co nsumptio n in summer to be reduced by 50 %.
Vario us building senso rs and metering devices were installed to co llect real-time o peratio nal data, pro viding data mo nito ring,
analysis, and co ntro l impro vement, with aid o f EMS and BMS, to realize o ptimized o peratio n and maximized energy
co nservatio n.
