Abstract

Thermal comfort and energy performance of public rental housing under typical and near-extreme weather conditions in Hong Kong

Revealing the Impacts of Passive Cooling Techniques on Building Energy Performance: A Residential Case in Hong Kong

“…The wings connect to the core and are the main occupancy area. Concord-type buildings present the advantages of a better building thermal performance and less hours of discomfort [33]. The concord-type layout is a common starting point for passive design analysis in Hong Kong.…”

“…Each floor is 2.75 m in height. From the study of Kwok et al [33], the concord type has a better thermal performance than other types of public housing layout. The windows follow the construction layout.…”

“…Hong Kong is hot and humid for most of the year and has a long cooling period [30]. Passive building systems are fundamental to achieve high energy efficiency and comfort in built environment [31][32][33]. The current development of the passive cooling design shows high potential for it to achieve high energy efficiency in buildings with access to its proper use [34,35].…”

“…Carefully chosen building orientation and location can maximize wind availability. Comparisons of simulation results among different public residential buildings in Hong Kong show clearly that certain types of layout (e.g., concord type) have fewer hours of discomfort in Hong Kong, even under the free-running condition [33]. Additionally, passive design in geometry and layout involves the early stage of design and thus usually requires no extra investment.…”

The implementation of energy-service contracts in the Republic of Sakha (Yakutia) as a tool to reduce government spending: experience and prospects

“…2) Thermal insulation of external enclosing structures up to the required standards of SP 50.13330.2012 using high-performance thermal insulation materials: mineral wool boards of M75-125 grades, spraying two-component foamed polypropylene on a rigid basis. At the same time, the requirement of installation of structures with minimization of "thermal bridges" is fulfilled [18][19][20][21][22][23].…”
