Building Energy Performance Survey (USAID/Vietnam Clean Energy Program)

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/越南清洁能源项目（USAID/Vietnam Clean Energy Program）的具体目标之一，是与五个城市的建设部门合作开发一个综合建筑数据库，以识别过去10年建成的几乎所有大型建筑（总建筑面积[Gross Floor Area，简称GFA]等于或大于2500平方米），即建筑存量（building stock）。

建筑存量样本（Building Stock Sample）包含约1400栋各类大型建筑，且代表了3个典型气候区：
• 北部地区（河内及海防市）：490栋建筑
• 中部地区（岘港市）：316栋建筑
• 南部地区（胡志明市及芹苴市）：623栋建筑

存量数据包含每栋建筑的基本信息，包括建筑类型、建造年份、总建筑面积；许多建筑还包含额外信息，如楼层数、电梯数量、发电机类型及规格等。

在详细的建筑能效调查中，该项目的方法是从建设部门的建筑样本存量中随机选取280栋建筑（占比20%）进行详细调查。

为确保收集数据的可信度，被调查建筑需在统计上代表每个气候区及建筑类型/规模类别。

所有数据均经过第三方质量保证审核。
