Residential building management and energy savings

In a previous post I commented on how the high-density residential market is not being driven by the same market forces as the commercial property sector to incorporate sustainability measures in the design/development of new dwellings.

So assuming that current building stock (i.e. those being built today) have a life span of 50–100 years. Thus, if the development stock currently being built is less efficient, what can be done to improve efficiency in the meantime? Continue reading

Energy savings in high-density residential

I wrote recently about the value of creating connections to nature in an urban environment.

I came across a striking statistic that really reinforces this point:

By 2030, 80% of City of Sydney residents will live in apartments and 90% of all new homes built will be in high rise apartment buildings.

A layman’s reading of this is that much of the benefits of energy efficiency in addressing emissions are going to have to come from improvements at the high-density residential level. Continue reading


Alex Laskey at TED

In a number of my workshops and presentations I’ve used the example of some research into the power of harnessing social norms to drive energy efficiency. And also how these same norms can have unexpected rebound effects. In preparation of a workshop I’m running in a few weeks’ time I came across Alex Laskey’s fantastic talk on the subject. Well worth a watch—he does a fantastic job of explaining how it all works and what they’ve found.


Greening your web page

A little while back, Blackle got a lot of coverage for putting forward some ideas about how web design can reduce electricity consumption. Unfortunately, the calculations of that particular approach, which centered on monitor energy consumption, have been widely debunked due to the now prevalence of LCD monitors.

The other day I came across a slightly different approach presented by Steve Souders [via Ajaxian] – which presents a rough calculation of how a reduction in page weight might reduce electricity consumption at the server side.

Interesting – especially if it holds up to scrutiny. What I like about it most is that it suggests that coding best practices, like web standards, server-side compression, and code optimisation, can actually have green benefits as we strive to reduce energy consumption.

Who woulda thunk it…
