1 – Introductions:

We all need a roof over our heads – 7 billion of us (and climbing)  in a resource and energy hungry 21st century. In a down (or biased) economy

The minefield of planning, costs, the technological constraints,  predicting the next 100 years for the house (even with best modelling)


New build, retrofit or restoration:
Costs are the obvious defining factors

Idealist will lean toward buying a new build with sustainable insulation, solar panels (water heating) or PV [Photovoltaic = electricity production]

Realist would pioneer real sustainability by working on the 95% of existing housing stock that communities exist in.  This is the better approach where you can involve your community by resource procurement, paid/voluntary building/remedial work, C&D [construction and demolishing] waste disposal, ….. and most important of all water management!


Davius actively encourage you to read as much information on the internet, in libraries and monthly magazines/journals such as Greener Building LINK: www.aecb.net  (AECB publication).

2 – Foundations:

Houses may be perceived as barriers to elements – foundations that separate us from the earth, when houses may be designed to work with the environment. Houses are some way away from ‘growing from the ground’ yet the foundations can do a lot to interact with the earth.

Ground to Air Heat pumps:

More and more attention is being focused on foundations to houses, flats, factories and offices


Sinks ………

Purify the ground –

For all the complaining of leaking

This can be a double edged sword –

A can do attitude of positive ground permeation and

3 – Floors:

Warning: Although the concept and practice of under floor heating is more efficient and better for overall space heating –


Please note that poor installation may result in cracked pipes – which will require the floors to be dug up for remedial work to be undertaken. Please ensure you use accredited and reputable (word of mouth recommendation may be best format forward)

4 – Walls:

It wou



Wall insulation is something that many will agree on – yet installing such products has led to disarray for many home users. Mould, ventilation problems and ????????

Davius can not stress enough

Living Space:

5 – Roofing:

The most important part



6 – Air in Buildings:

Air in houses:

Having good

Arguments of ACH vs air tightness vs



7 – Energy and Buildings:

It wou

Energy in houses:

Energy efficiency should come first before energy generation considerations – using the old analogy of ‘if it ain’t broke – don’t fix it” NOOOOOOOOOOOO – that harbors poor consideration NOT to be innovation


Air / Ground exchangers:

Ground / Heat exchangers:

Micro generation:




Wood Burning:

Please do NOT burn domestic waste in your home.

Additional info?

Although Housing and Renewables are becoming inextricably linked – this page will focus on dominantly on sustainable housing. No claim can be made that this is comprehensive as the international community of sustainable housing/construction is going in some very exciting directions and new developments are assured.

8 – Water and buildings:

It wou

Water in houses:


Our most precious resource – humans are approximately 75% water, the earth is approximately 75% water. REFERENCES???????????????? yet what we effectively do with it (and ensure it is shared equally)

This is not just an issues of ‘save water to save the environment’ yet creating balance so you have water stored for drought periods and equally you have water storage capacity when potential flooding periods are imminent. There is no perfect solution that we have developed – yet sometimes a little inspiration should help.


As defined

More and more humanity is embracing the four seasons and its input/output cycles – just as we are naturally ?????????????????????????????????????????????????????????????????????????????????????????????????????????

With a causal effect of people leading be example and this encourages others to take up sustainable methodologies – domestic housing can contribute a significant rich improvement upon drought and flooding conditions.

Every practice begins with a small idea.

9 – Your car and your home:

It wou



Transportation are now becoming an increasingly integrated part of our homes. As electric bikes, electric cars and electric vans

Several countries provide grants and economic incentives ……….

Car scrapping

Cars over ten years old may be

We all fully recognise that when innovation comes to market, it may have a price premium yet the more consumers purchase them the costs will outright costs will reduce.

10 – Landscaping and your home/street/area: Biodiversity / Drought & flooding – creating a balance!

It wou



Flooding from blocked sewers/fatbergs or irresponsible dumping or even poorly maintained sewer systems can bring local areas to a standstill.

Many people take more pride in their streets as well as their homes. with more citizenship undertaken in terms of adding surveillance to safeguard the street, more importantly people who contribute to keeping their streets clean!

Drought / Flooding: creating a balance!

This is a real issue

11 – Final words:

No matter how much knowledge is out there, experience (both professional and experimental) ……………. It is your home and the decisions are yours. You may stumble on a new home practice or home methodology that improves your home performance and improve your quality of life.
