Abstract
Since 2011 when the nearly-zero energy building (NZEB) has been initialized,
about 10 million square meters of built and under-built projects have been established.
The indoor environment quality of NZEB demonstration projects has been greatly
improved, together with sharpe decline in building energy consumption. NZEB
development has shown the tendency of large-scale promotion from single building. In
order to impel this large-scale-popularization of NZEB, this report carries out four main
tasks, which are respectively: research on existing NZEB incentive policies, research
on market-oriented evaluation system, industrial development forecast and best case
study.
(1) 47 NZEB-related incentive policies on from 10 provinces and autonomous
regions, 16 cities have been studied and subusumed into 3 categories according to the
publishing department property, policy coverage and content of the documents, which
are respectively: governmental documents, developing documents of construction field
and building science, and special supporting documents for NZEB. Therefore, this
report analyzes the characteristics, contents, quantity and regions of all kinds of
documents and the development trend of NZEB policies from the aspects of policy
system, incentive strength, development objectives, level promotion and coverage.
Furthermore, through the analysis of the effectiveness and replicability of various
specific incentive methods, combined with the specific situation of each region, policy
recommendations of the 14th-five-year plan period have been proposed for different
regions.
(2) International technical system for NZEB evaluation and identification
has been studied in order to support the promulgation of the evaluation
management measures of NZEB by China Building Energy Conservation
Association. The NZEB evaluation standard has been organized and published
which allowed the accomplishment of the evaluation of the first 12 projects in
2019, including 6 ultra-low energy buildings, 5 nearly- zero energy buildings and
1 zero energy building.
(3) Incremental cost ubformation of 64 existing demonstration buildings
