Building Energy Performance Survey Data

One of the specific objectives of the USAID/Vietnam Clean Energy Program is to develop a comprehensive database of buildings in collaboration with the Departments of Constructions in five cities to identify almost all larger buildings (with Gross Floor Area [GFA] equal to or greater than 2,500 m2) that have been constructed during the last 10 years (building stock). The Building Stock Sample contains some 1,400 large buildings of all categories and representative of 3 typical climate zones: • Northern zone (Hanoi & Hai Phong cities): 490 buildings • Central zone (Danang city): 316 buildings • Southern zone (Ho Chi Minh and Can Tho cities): 623 buildings The stock data contains basic information for each building, including building type, year built, total floor area; many buildings contain extra information such as number of stories, number of lifts, type and size of electric generator, etc. For the detailed building energy performance survey, the Program’s approach is to randomly select 280 buildings (20%) from Departments of Construction sample stocks of buildings for a detailed survey. For the credibility of collected data, surveyed buildings must be statistically representative of each climate zone and building type/size category. For each climate zone, the optimal sample size will contain at least five buildings in each of the building categories. All data went through a third party quality assurance check.美国国际开发署（USAID）越南清洁能源项目的具体目标之一，是与五个城市的建设部门合作搭建全面的建筑数据库，以识别近10年内建成的几乎所有大型建筑（总建筑面积[Gross Floor Area, GFA]≥2500平方米），即建筑存量（building stock）。该建筑存量样本涵盖约1400栋全类别大型建筑，覆盖3个典型气候区： • 北部区域（河内市与海防市）：490栋建筑 • 中部区域（岘港市）：316栋建筑 • 南部区域（胡志明市与芹苴市）：623栋建筑 该存量数据包含每栋建筑的基础信息，涵盖建筑类型、建成年份、总建筑面积；多数建筑还附带额外信息，如楼层数、电梯数量、发电机类型与规格等。针对详细的建筑能源性能调研，本项目采用的方案是从各建设部门提供的建筑存量样本中随机抽取280栋建筑（占比20%）开展详细调研。为保障采集数据的可信度，被调研建筑需在统计层面能够代表各气候区及建筑类型/规模类别。针对每个气候区，最优样本规模需确保每个建筑类别至少包含5栋建筑。所有数据均经过第三方质量核查。
