1Passive cooling has 2 main objectives
1. eliminate [blank_start]unwanted heat gains[blank_end] as much as possible
2. [blank_start]generate passive cooling[blank_end] potential wherever possible- Aunwanted heat gains
- Bgenerate passive cooling
2Eliminate heat gains
1. [blank_start]heat gain in summer[blank_end] can be due to
- [blank_start]solar radiation[blank_end]
- [blank_start]high ambient air temp outside[blank_end]
- [blank_start]internal heat gain[blank_end] from [blank_start]occupancy, equipment and lighting[blank_end]
2. [blank_start]solar[blank_end] [blank_start]radiation[blank_end]
-through [blank_start]windows[blank_end]
-[blank_start]opaque[blank_end] (non-transparent) elements via [blank_start]heat transfer (walls)[blank_end]
3. best and simplest way [blank_start]to keep heat gains low[blank_end] is [blank_start]prevent solar radiation[blank_end] to [blank_start]reach windows[blank_end] and [blank_start]opaque elements[blank_end] in the first place this can be achieve by

2. install [blank_start]openable windows[blank_end]
-use [blank_start]landscaping elements[blank_end] to [blank_start]channel breezes[blank_end]
-[blank_start]reduce internal barriers to ventilation[blank_end] (walls)
-properly [blank_start]locate and size windows[blank_end] for [blank_start]cross ventilation[blank_end]
3. use [blank_start]wing walls/fin walls[blank_end] to [blank_start]guide the wind[blank_end] through [blank_start]pressure[blank_end] differentials
4. use [blank_start]roof outlets[blank_end] to [blank_start]guide the wind through[blank_end] [blank_start]pressure differentials[blank_end]
5. use roof outlets to guided the wind through pressure differentials
6. use [blank_start]stack ventilation[blank_end] to create a [blank_start]chimney affect[blank_end]
- [blank_start]two openings on opposite[blank_end] external faces of a space, [blank_start]one[blank_end] of which is [blank_start]connected to a vertical rise[blank_end] (chimney or atrium)

16Two kinds of ventilation offer the option for [blank_start]cooling[blank_end]
1. [blank_start]comfort[blank_end] ventilation
2. [blank_start]night purge[blank_end] ventilation- Acooling
- Bcomfort
- Cnight purge
17[blank_start]Comfort[blank_end] ventilation
-in [blank_start]summer[blank_end] when internal temp get to hot, [blank_start]open the window[blank_end] to allow for [blank_start]air to flow across ocupants[blank_end]
- [blank_start]ventilation[blank_end] can [blank_start]raise effectiveness[blank_end] of [blank_start]weating and cooling the body down[blank_end] [blank_start]more than[blank_end] [blank_start]still air at a lower temp[blank_end]

- Jindoor temp is > outdoor air temp
18[blank_start]Night-purge[blank_end] ventilation
-works in most [blank_start]climates[blank_end] except [blank_start]hot and humid[blank_end] because [blank_start]night temp to close to day temp[blank_end]
-most [blank_start]useful in hot and dry climates[blank_end] where the [blank_start]diurnal outside temp difference[blank_end] are significant
[blank_start]Day[blank_end]
1.during the day [blank_start]all openings are closed[blank_end], only [blank_start]minimum necessary air change is allowed[blank_end], [blank_start]heat gain minimised[blank_end]
[blank_start]Night[blank_end]
2.[blank_start]cold night time air[blank_end] introduced [blank_start]into the building[blank_end] to [blank_start]flush out the heat[blank_end] of the building

19[blank_start]Radiant[blank_end] cooling
- all [blank_start]bodies emit heat[blank_end] through [blank_start]radiation[blank_end]
- a [blank_start]building will cool[blank_end] if the [blank_start]net flow is to the outside[blank_end]
-[blank_start]night building radiate[blank_end] to [blank_start]clear sky[blank_end] [blank_start]not a cloudy[blank_end] one
-[blank_start]roofs[blank_end] are in the [blank_start]best position to radiate[blank_end]
- to [blank_start]achieve radiant cooling[blank_end] the [blank_start]radiator needs to be exposed[blank_end] to the [blank_start]outside at nigh[blank_end]t but [blank_start]protected from the sun radiation[blank_end] during the [blank_start]day[blank_end]
-[blank_start]roof is the radiator[blank_end], so [blank_start]strategy restricted by one storey[blank_end] high buildings
How it works
1.[blank_start]cooling medium in pipes[blank_end] incorporated in [blank_start]thermal mass (ceilings)[blank_end]
-can be used to [blank_start]increase[blank_end] the [blank_start]function[blank_end] of the element as a [blank_start]heat sink[blank_end]
-[blank_start]reversely a heating medium will heat[blank_end]
- [blank_start]thermal mass influences comfort[blank_end] by [blank_start]radiant exchanges with the skin[blank_end]. [blank_start]Human body[blank_end] is most [blank_start]sensitive to radiant heat loss[blank_end] e.g. [blank_start]CSET, termodeck systems[blank_end]- ARadiant

20[blank_start]Evaporative[blank_end] cooling
1. if [blank_start]fresh air can be cooled before[blank_end] [blank_start]entering the building[blank_end], [blank_start]natural ventilation[blank_end] can be [blank_start]considered[blank_end] as an option [blank_start]even in climates[blank_end] with relatively [blank_start]high daytime temps[blank_end]. which can happen through [blank_start]evaporative cooling[blank_end].
-when [blank_start]water evaporates sensible heat[blank_end] is [blank_start]turned int latent heat[blank_end] in form of [blank_start]vapour and temp drops[blank_end]
2. simplest way is to [blank_start]draw air through[blank_end] large areas of [blank_start]vegetation over a cooling pond[blank_end]- AEvaporative

21[blank_start]Evaporative[blank_end] cooling 2 systems
1. [blank_start]direct evaporative cooling[blank_end]
- [blank_start]water evaporates[blank_end] in the [blank_start]building[blank_end] or [blank_start]in the fresh air intake[blank_end]
-[blank_start]air is not only cooled[blank_end] but also [blank_start]humified[blank_end], only [blank_start]appropriate in dry climates[blank_end]
Example: [blank_start]Passive evaporative down draught cooling[blank_end] at the [blank_start]Zion National Park Visitor centre[blank_end], [blank_start]USA[blank_end]
2. [blank_start]indirect evaporative cooling[blank_end]
-[blank_start]air is cooled by evaporation[blank_end] but the [blank_start]indoor air is not humidified[blank_end]
-f[blank_start]loating insulation[blank_end] maybe used [blank_start]instead of second roof[blank_end] to [blank_start]protect water[blank_end] from [blank_start]sun[blank_end] and [blank_start]heat[blank_end]- Adirect evaporative cooling

22[blank_start]Roof pond heating and cooling 1[blank_end]:
-can be [blank_start]used to provide heating[blank_end]
-[blank_start]store of water above the roof[blank_end] used to [blank_start]absorb solar radiation[blank_end] during the [blank_start]day[blank_end]
-at [blank_start]night[blank_end], the [blank_start]water is covered with insulating panels[blank_end] and the [blank_start]stored heat warms the ceiling[blank_end] and [blank_start]radiates down into spaces below[blank_end].
[blank_start]Roof pond heating and cooling 2:[blank_end]
-[blank_start]no convection current is created[blank_end], however as [blank_start]warmed air[blank_end] tends to [blank_start]remain beneath the ceiling,[blank_end] the distribution of [blank_start]collected heat is by radiation only[blank_end]. therefore the [blank_start]proximity[blank_end] of the [blank_start]ceiling[blank_end] to the [blank_start]individual being warmed[blank_end] is important as [blank_start]radiation density drops off quickly[blank_end] with [blank_start]distance[blank_end]- ARoof pond heating and cooling 1
