Passive Design- Passive solar heating

Fossil fuel resources are not ❌, so the price of it will rise in the future. ❌ energy ❌ will be developed further and might get ❌, however they still need an initial ❌.

Sustainable Design: The ❌ ❌
❌ energy
Mechanical ❌ and ❌
❌ systems
❌ building design

Renewable energy- Mechanical heating and cooling
However the ❌ system won't be ❌ enough to be powered by ❌ energy or passive systems won't work. Basic building design must be ❌ responsive.

Passive Design
-Passive design is a key element of ❌ construction
-Maximise ❌ + minimise ❌ use
-only use the energy available locally (nothing new: similar to vernacular architecture)
-uses the ❌ flow of energy prevailing on site and works with it
1. to ❌
2. to ❌
3. to ill❌
4. to ven❌ a place

Passive Design.
has been ❌ by a design which generally uses little ❌, and is highly energy efficient.
with this new interpretation of passive design small mechanical "❌" ❌ can be used to achieve user ❌.

Passive Design
-low ❌ and energy ❌ buildings means careful considerations of ❌, ❌, ❌ and ❌ systems
-❌ ❌ means of heating, cooling and ventilating needs to be ❌ when it would be beneficial but has to be eliminated if detrimental to a comfortable ❌ ❌.

Passive Design
-uses the following principles to improve on the ❌ ❌ and ❌ performance of a building
1. ❌
2. ❌
3. ❌
4. ❌
5. ❌
6. ❌

The building ❌ chart
-used as a tool to decide what ❌ are valid for the ❌
Procedure
-plot 2 points
1. monthly average ❌ temp with the ❌ rh
2. monthly average max ❌ with the min ❌
- then link both points for each month
- each ❌ will represent the hange in temp and rh over and averge ❌
- one "pair" of data = 1 point
- one line = 1 month

Passive ❌ heating
- technique that uses ❌ of the ❌ to ❌ a buildings ❌ without using other ❌ ❌
- successful use of passive design depends upon
1. the ❌ understanding of ❌ ❌
2. the best use of ❌ and their ❌ in order to capitalise on the solar energy

Main objectives of solar ❌
1. to ❌ all ❌ of heat ❌ from the building

Passive solar heating

Passive solar heating system involves
