Accidental climate

A new microclimate

Finishing the greenhouse and moving it into place has created an unexpected bonus

Where the light and heat bouncing off the rainwater tank was previously being lost over the pond, now the greenhouse traps it and keeps it in the area between the two.

The result is a pleasant microclimate that is a couple of degrees above the norm. I’m not sure exactly how many degrees, but you…

Micro-Climatic Studies: Malaysia

The starting point to all projects should be a rigorous understanding of the micro-climate and its site-specific impact (Pomeroy 2011).

Case Study: Malaysia

Principles in addressing tropical climate measures in Malaysia:

Orientate the development to present the shorter building facade faces towards the east and west, thus reducing solar heat gain

Use low thermal mass building materials to mitigate heat transmittance and storage

Keep out direct sunshine and reduce direct solar radiation by using deep overhangs and shading devices

Maximize natural ventilation by orientating building toward prevailing wind direction, but ensuring that solar orientation takes precedence over wind orientation

Arrange rooms and openings to harness cross ventilation

Employ larger, unobstructed internal volumes to increase air flow

Incorporate pitched roofs to facilitate water drainage 

Where possible, elevate building structure to increase air permeability

Enhance natural vegetation to reduce urban heat island effect due to the shading and carbon-sequestrating properties of flora and fauna

Dwellings in cool temperate climates:

Square to rectangular floor plans to be orientated to minimize solar gain during summer and retain a thermally beneficial compactness during winter

Using materials of a greater thermal mass for summer ventilation

Windows face equator to collect winter sun

Shading used to counteract the summer sun

Dwellings in hot arid climates: 

Courtyard spaces and/or passive cooling structures that help ventilate and provide natural light

Using materials of high thermal mass to prevent extreme heat and retain cool interior

Materials are usually lightly colored to reflect solar radiation and avoid thermal gain

Dwellings in hot and humid climates:

Rectangular floor plans that allows orientation of shorter faces to the East and West to reduce solar radiation 

Plans are as unobstructed as possible and elevated to encourage air flow and cross ventilation 

Using light-weight materials with low thermal mass to avoid heat gain and internal heat transfer
