Cooling demands of commercial buildings present a relevant challenge for sustainable future. They account over half the overall energy needs operation an average office building in warm climates, and this situation is expected to become more pressing due increasing temperatures cities worldwide. To tackle issue, it widely agreed that application passive strategies should be first step design efficient buildings, only using active equipment if truly necessary. Nonetheless, there still further...

In the Kingdom of Saudi Arabia (KSA), residential buildings’ energy consumption accounts for almost 50% building stock electricity consumption. The KSA’s economy relies heavily on fossil fuel sources, namely oil reservoirs, whose depletion will negatively affect future development country. total is growing by approximately 5–8% annually, which would lead to production and being equal in 2035. Therefore, buildings need further assessment as regards their current This research used a survey...

This paper seeks to present a panorama of cooling related research in office buildings, categorising reported experiences from the past 25 years order identify knowledge gaps and define current paths trends for further exploration. The general goal behind this is support design sustainable buildings warm climates through examination experiences, thus focuses on strategies at building level specially with façade design. Peer reviewed journal articles were selected as source study, given...

Solar cooling systems have gained increased attention these last years, for its potential to lower indoor temperatures using renewable energy. However, architectural integration of in buildings has not been fully explored. Current developments such as small scale solar driven heat pumps and kits commercially available application raise questions about how successfully integrate into buildings, while present interesting opportunities the development new performance based façade components or...

Increasing cooling demands in the built environment call for innovative technical solutions and systems application buildings. Cooling loads represent an important share of total energy consumption warm climates, especially commercial office Moreover, mechanical will still be needed most cases to cope with loads, even after considering passive strategies design building its façade. Solar technologies present interesting assets, being based on environmentally friendly processes, driven by...

The implementation of Nearly Zero-Energy Buildings (NZEB) renovation packages in Europe needs to be accelerated meet the current decarbonization goals. To achieve this level performance, building strategies should shift towards solutions that incorporate a multitude passive and active components, increasing complexity costs execution. Moreover, it requires involvement different stakeholders supply-chain, resulting additional difficulties communication coordination processes. address...

Bio-receptivity refers to the aptitude of a material allow for natural growth small plant species on stony surfaces with minimum external influence. Despite numerous associated environmental benefits, mosses and lichens facades has always been viewed as negative phenomenon due random shabby conditions. This research dealt design self-sustaining bio-receptive concrete facade system an aim create more sustainable green construction industry. The used surface geometry variable facilitate moss...

In the Kingdom of Saudi Arabia (KSA), residential buildings’ energy consumption accounts for almost 50% building stock electricity consumption. The generation consumes over one-third daily oil production. KSA was ranked as one highest countries in fossil fuel per capita 2014. Moreover, KSA’s economy heavily relies on sources, namely reservoirs, whereby depletion will negatively affect future development country. total is annually growing by approximately 5-8%, which would...

The circular economy is a widely accepted concept that various governments have started to adopt. Still, major consumer of resources, the construction industry, struggles implement business models answer opportunity and generate value beyond economical. At same time, industry at threshold intensifying their production by industrialized manufacture. This type offers practical benefits should be developed whilst prioritizing sustainably built environment. A model (CBM) all stakeholders long...

Increased urbanisation will put an increasing strain on our green spaces, which is expected to have a significant effect physical and mental health, as well the health of ecosystems. As such it important integrate more spaces in urban fabric. One way doing this by making use so-called bioreceptive concrete façades other structures, allows for biological growth take place substrate itself, without requiring any additional systems or maintenance. However, challenge create affordable mixture...

Extreme heat is an increasingly serious problem for cities, which requires urgent exploration of strategies at different scales to build climate resilience. The aim this study measure the impact façade design on local thermal response in city centres. Building envelopes have a relevant role characterization environment dense areas, due their radiative effect towards urban canyon. focused two variables: material and geometry, configurations outdoor response, measured through resulting surface...

Solar energy has been actively promoted as a clean source since 1973’s oil crisis, evidenced by the emergence of initiatives such Heating & Cooling Programme International Energy Agency or US Department Energy.  Nonetheless, solar technologies have not widely used in built environment, limiting their operation to industrial and macroscale applications.  Commercially available products building integrated PV panels (BIPV) thermal collectors (BIST); novel prototypes concepts for cooling...

Overheating, glare, and high-energy demand are recurrent problems in office buildings Santiago, Chile (33°27'S; 70°42'W) during cooling periods.
