“…The integrated model is based on the Urban Microclimate Model (UMM) (Huang et al 2015) and a Building Energy Model (BEM) of HTB2 (Jones, Phil;Lannon, Simon;Li, Xiaojun;Bassett, Thomas;Waldron 2013). The UMM provides localized external zone air temperatures to HTB2, while external building surface temperature and HVAC exhaust data, calculated by HTB2, are returned to the UMM on an hourly time step.…”

“…The Urban Microclimate Model (UMM) is a multizone airflow network model (Huang et al 2015) that can be used to assess the mass and energy of the air in urban environments. It uses a simplified approach that was first developed to describe indoor environments (Musy et al 2001) and later applied for outdoor spaces (Rao et al 2011).…”

“…However, this does not account for microclimate related external temperatures and wind flow. The Urban Microclimate Model (UMM) (Huang et al 2015) uses a multizone airflow network model to assess canopy layer airflow in high-density cities, where air mass flow within an interconnected network of external zones is driven by pressure and density differences. This paper presents the development an integrated model, which couples a multizone urban microclimate airflow network model (UMM) with the building energy model (HTB2).…”

The energy performance of an urban building depends on its surroundings. Existing building energy models are limited in accounting for micro-scale variations of the surrounding environment, which may significantly modify building energy performance in high-density cities. Modeling of building energy at urban scale remains a nascent field. This paper presents an integrated urban microclimate (UMM) and building energy model (HTB2), which has been developed to assess the energy performance of a cluster of buildings and their external environments in high-density cities. The simulation results were evaluated by comparison with field measurement data collected from the Sai Ying Pun neighbourhood in Hong Kong. The model has potentials to support building design and urban planning at early stage.
