Green building should aim to cause the minimum possible harm to the environment and users – throughout their design, construction, use, upkeep and eventual end of life recycling. Despite green and sustainable construction becoming increasingly popular, this comprehensive, cradle to cradle philosophy is not yet common practice. We aim to promote this building model with our Eco 4 design.
Green building, as a concept, is straightforward and makes perfect sense. It means making thoughtful design choices and using ecological materials in ways that create quality, long- lasting environments with minimum damage to the planet. Natural ambient resources can often be used for services – energy – heating – cooling – water etc.
Building to a green agenda now has widespread support and there is no shortage of products and techniques. Whether you are drawn to use timber from sustainable sources, lime based renders, plasters and paint – or to harvest the rain, sun and wind we can source some amazing products and people who can help you.
For green buildings to make a real difference, they must be practical designs which we can all have and afford. Cost-efficiency is a pre-requisite for sustainability, because income generation usually has environmental consequences. Green designs do not have to be complex or costly.
We promote value for money, engaging responsible suppliers and subcontractors; local sourcing of goods and services and fair employment to boost local business and facilitate future business opportunities. The Balance between cost and environmental impact will be fully considered in all projects executed by AJ Saville Builders. This will include cost benefit analysis exercises, fair employment practice, use of local material and services from responsible sources, consideration of low impact materials, and reuse of existing resources.
There are a number of key aspects that we work on with the Architect at design stage, some being:
- Cost-efficiency (a pre-requisite for sustainability)
- Conservation of energy and resources
- Ecological foundations and minimal site intervention
- Elimination/Reduction of material and resource wastage
- Super insulation and ecological thermal energy storage
- Use of natural (passive) heating and cooling
- Use of natural lighting (for health and energy saving)
- Long life- low maintenance, robust design
- Green surrounding- design with nature and climate
A building is not just a machine or a lock-up for our possessions, but something we intimately live with, that we care for and love.
We believe that good natural lighting and solar space heating can be achieved without massive areas of high-embodied-energy glass. Glazing areas should be sized appropriately for the orientation, construction and type of building, together with the provision of adequate shading and ventilation to avoid summer overheating.
In Central Otago ventilation is an increasingly challenging area of design with extremes in temperature. Homes here require a system that can provide adequate fresh air in winter, without heat loss in varying weather conditions, but can also provide summer cooling during heat-waves.
