Post disaster preparation takes a certain mindset; bad things do happen sometimes.
Enquiry from potential clients usually begins with solar but as the discussion grows can see where their mind is.
Post disaster systems are on standby and work when power is cut off. They work when sanitary council water supply has disappeared. Water is heated and used when power and water is cut off from utilities. Warmth and cooking are possible without power or gas.
The difference in post disaster systems is clear from the efficiency or green energy enquiries.
Each property will have individual requirements on how long the service would be expected to last, how many people to keep comfortable and clean. This takes careful design and in-depth knowledge of suitable products on the market.
We enjoy these projects as it uses all of our specialties and skill-sets in a single project. Having completed several post-disaster rated property’s we find it very satisfying.
We are talking about solar water heating without power, heating water with wetbacks and fires, cooking with fires or solid fuel ranges and home heating, stand-by generators, large breakwater tanks and pumps for fresh sanitary water supply, having stored gas as back up energy source, collecting rainwater for water storage and use, disposal of sewerage and wastewater.
Sustainability is a common catch word with regard to lifestyle these days and the best indicator of sustainability is whether your home will sustain you after a disaster. Most do not. The all electric home will not serve you well in this situation; a diverse energy supply is paramount. Gas water heating with a solar collection system, standby generator with manual changeover switch are basic but necessary. Standby water collection, size depending on personal budget. Food etc.
Here in NZ we are susceptible to this event, it provides a unique set of variables of its own. Transportation when travelling the country will probably fail leaving you stranded. A get-home bag with the basics – fire-starting ability, poncho, food water, etc. There are many YouTube videos showing what you need so it’s not necessary to go over that here. If at home power is a must, but only to keep your fridge going. Woodfire for cooking and hot water. If a generator is available to run an infinity for ignition. Gas is the only portable energy source, 45kg cylinders last months. Emergency food for 3mths would be a requirement. Water of course, as much as you can afford to store.
With air travel taken for granted the rapid spread of pathogens will create serious risk. Anti-viral facemasks are available on any auction or buy-site, they are cheap. Literally in a viral event especially when advised by your government, don’t leave home without it! Hand sanitizers are a must, especially with children.
Although not often thought about, we are overdue for a class Y flare that would cause no end of problems on an electric driven planet as we have. The only EMP protection we have available would be an EMP blanket containing a lattice of copper or stainless ribbons to disperse the high energy signal. Protection of about 80db should suffice, using 80 denier copper woven sheeting, again budget dictates your level of protection. While protection of a vehicle would cost around $1k, protection of an entire garage would cost about $10k. With 8 hours of warning which would be usual, there is every chance of moving your most valuable electronic items undercover.
Get the best locks possible – keep them out! Keep lights off at night, basic common sense will rule. Cameras with a standby UPS (uninterruptable power supply) are your best force multiplier for your home – it saves a lot of patrolling time. Your will to survive will dictate your level of security, the self-defence laws in NZ are still there for you. I don’t need to say anymore.
These are only some of the risks we face but most have the same common solutions, shelter, power, water, food, and security. Unless you live in a city where staying in the midst of a high-density population will create a unique set of risks, staying home is my first choice, shelter, water, and food are there; you can only carry so much, probably only a few days worth. Remember everyone else is “bugging out” to the same place.
Consider us if considering part of or all of these systems and can recommend other contractors with experience with this unique subject.
