How to build the perfect house of the future.
Before you start reading this case study, let us state a couple of points about our mission in life.
We have strong views about the democratisation of energy. This means that we want people to be energy independent or as close to it as possible. We see the end of centralised energy distribution arriving over the next 10 years, and we start people on that journey today. The current model where you “rent” your energy each month makes many people (not you) a lot of money in profits and taxes. We believe you should keep your money and get the full benefit of real renewable energy technology that you “own”.
Your government, however, DOES NOT want this as they collect billions in taxation off the back of energy purchases, so every solution proposed by Government will still keep you buying lots of energy and paying lots of taxes long into the future. Hence, the government frantically promoting Heat Pumps means you produce NO free usable renewable energy and will have to purchase 100% of your heating, hot water & electricity long into the future.
By using a HONE system in your new build, your life, yor comfort and your finances will be transformed.
- This case study is based on a real home; the QS pricing and savings are real, as is the cost of the HONE system.
- You will have purchased 4 Heat Pumps during the design life of the HONE system of 50 years.
- HONE Thermal/Electric systems make 100% free clean, renewable energy using daylight, not sunlight.
- The construction costs are roughly €35,000 cheaper & use 90% less annual energy than if it had a Heat Pump.
- The home has virtually no maintenance, unlike a Heat Pump with daily, monthly & annual maintenance.
This case study will show you how to build the perfect home for the future.
We will show you three energy rating options for building your home. However, we won’t showcase a basic A2 nZEB option as HONE systems easily meet A1 Super nZEB and beyond.
-
A1 Super nZEB Option 1.
- This option means that your house will require less than 25 kWhrs per sqm/year to operate.
-
A1 Net Zero Option 2.
- This option is Net Zero; it means that your home will make the same amount of energy as it consumes. This home is also zero carbon.
-
A1 PEB Option 3. (Positive Energy Building)
- This is the ultimate home; this makes more energy than it consumes. It also acts as a carbon sink.
Note; the type and size of house you are building is irrelevant. This case study applies to concrete block, timber frame, modular or any house type.
These are the following specifications: (NOTE, the FULL SEAI DEAP files below show the full construction specifications, so we will only highlight the important ones.)
- House size – 165 sqm (1,776 sq ft)
- Wall U Value – 0.13
- Windows – Double Glazing, u-value 1.0, ST – 0.7
- MHRV Whole House Mechanical Heat Recovery System
- Air Tightness Test of 0.15 ac/hour
- Standard low-cost central heating system with radiators/towel radiators
- Micro oil boiler
- 2 Mixer showers
- 1 Bath
- HONE Thermal/Electric Renewable System
- 300L customised cylinder
- Low Energy Lighting
Other important notes
- No vents; cooker hood is a passive house cooker hood, not requiring an external vent.
Operational & Maintenance
Turning on the heating with a HONE system is simple and easy. It can be from the programmer or simply do it from a smartphone whilst watching your favourite tv program. Unlike a heat pump, the house will have extraordinary levels of comfort as your heating system will be a high-temperature heating system unfazed by challenging cold weather events.
But the largest benefits come from the reduced cost of construction, the virtually zero maintenance interaction and cost. With annual energy bills typically 90% lower than heat pump configurations, the answer is obvious.
