Forest microclimates: Investigating the performance potential of vegetation at the building space scale

Lag Time of Heat Conduction in Conditions of Growing Greenery Cover on Flattop-Concrete Roof of Single-Room House with Lightweight-Concrete Walls as Constructed on Narrow Space in Bangkok

“…Anyhow, the reradiating heat energy from ceiling of flattop-concrete house was supposed to be the main factor involving with less changing room temperature due to high heat conductivity. Since the decrease of sensible heat flux on flattop-concrete roof and surroundings was absorbed to change into latent heat flux by green plants through the evapotranspiration processes before heat energy translocation to the ceiling of the room as pointed out by Gates (1965;1980), Geiger & Todhunter (2003), Abou-Korin (2014), Ashktorab et al (1989), Botkin & Keller (2011), Bowen (1926, Chun & Guldmann (2014), Chunkao (1971;1979;2004), Coseo & Larsen (2014), Maimaitiyiming et al (2014), Mangone & van der Linden (2014), Heilman & Brittin (1989), Holland et al (2013), Honjo & Takakura (1990, Lee et al (2004), Verma et al (1978), Wolf et al (2008).…”

“…As stated before, this section of research was needed to focus on feasibility study of water usage for evapotranspiration from experimental pots containing coconut flake with and without planting Pudsaon or Cape Jasmine (Gardenia jasminoides J.Ellis) in order to determine heat absorption from incoming solar radiation and including outgoing re-radiation from KU College of Environment building, water body in canal and asphalt road as described by Odum & Barrett (2004), Akbari et al (1992), Honjo & Takakura (1990, Ferreira & Condessa (2012), Mangone and Van der Linden (2014), Ng et al (2012), Oke et al (1991), Santamouris (2014), Zhang et al (2013) and McPherson (1993). It was expected that the experimental pots containing coconut flake with and without planting Pudsaon used water through evapotranspiration process could make room temperature decreasing (Juwarkar et al, 1995;Hammer, 1989;Ahn & Mitsch, 2002;Jenssen et al, 1994;Keddy, 2010;Bowen, 1926;Lai et al, 2011;Dicken et al, 2013;Gates, 1980;Hartman, 1994;Holland et al, 2013;Coseo & Larsen, 2014).…”

“…Giving greenery cover and tree planting in urban areas have been suggested by Mangone & Linden (2014), Akbari et al (1992), McPherson (1988), McPherson & Rowntree (1993), McPherson & Simpson (2003), Coseo & Larsen (2014), Zhang et al (2013), Honjo & Takakura (1990), Alchapar et al (2014), Oke et al (1991), www.ccsenet.org/mas Modern Applied Science Vol. 9, No.…”

“…9, No. 9;2015 Shahidan et al (2012) while Chun & Guldmann (2014) to introduce the roof-top green cover and water areas as well as giving vegetative courtyard and city parks to deduct urban temperature by Mangone & Linden (2014), Skoulika et al (2014), McPherson (1988), Takebayashi et al (2014) and Ng et al (2012); and also making higher reflecting roof by Alchapar et al (2014). Theoretically, an incoming heat protection by tree planting, pond construction, green patches around the cities or houses, and green-top-roof buildings in urban heat island would be the most important to reduct ambient air temperature due to make them away from exactly sources and sink in heat transfer by re-radiation and heat absorption before re-radiation taking place (Gates, 1965;1980;Hartman, 1994;Geiger, 2003;Perez et al, 1999;Chunkao, 1979;Bowen 1926).…”

“…In other words, built houses and buildings should be used lightweight concrete blocks for reducing heat transferring by decreasing the thermal conductivity in order to live with cool temperature. Truly speaking, the houses and buildings wish to grow trees around them, it could be made cooler temperature inside them for more convenience and comfort with high energizing routine works (McPherson, 1988;McPherson & Rowntree, 1993;McPherson & Simpson, 2003;Garratt, 1978;Ng et al, 2012;Mangone & Linden, 2014).…”
