Building a single-family house is a unique moment: exciting, but also full of decisions that will affect your comfort, operating costs and independence for the next decades. One of the most important decisions that should be made and taken into account at the design stage is the preparation of a building for renewable energy sources - renewable energy sources.
In this guide, we show you step by step how to plan a house of the future that will be warm, cheap to maintain and ready for clean energy flowing from nature.
Why is it worth planning RES before building a house?
Most investors postpone the decision on heating and energy systems until the last moment. This is a big mistake. Later installation of a heat pump, photovoltaics or an energy storage is associated with costly modifications, additional works and sometimes ... simply the lack of technical possibilities.
RES planning even before construction allows:
- optimize the layout of rooms and roofs,
- avoid cutting walls or changes in installations,
- take advantage of subsidies such as "my heat",
- Choose the best solution to your family's needs.
This is a chance to pay less and live more comfortably from the first day in your new home.
What is worth planning in a house ready for renewable energy?
Today, an energy-efficient house is not a luxury, but a reasonable standard. In practice, this means the use of several cooperating solutions that will ensure comfort and low costs throughout the year:
- air-to-water heat pump - Modern, maintenance-free source of heat and domestic hot water.
- Photovoltaic installation - Free electricity from the sun, especially profitable in conjunction with the pump.
- Energy store - It accumulates surplus electricity from PV and increases autoconsumption.
- Air conditioning with heating function - Comfort in summer and additional heat source in transition periods.
Such a combination makes the house gain not only a modern character, but above all - real savings and energy independence.
The most common mistakes in building a house from renewable energy
Here are the most common bugs we see as a company that assembles thousands of installations annually:
- No prepared space for the outdoor pump unit (e.g. under the bedroom or on the terrace).
- Too small switching station - no reserves for PV or warehouse.
- Forgotten cable culverts or pipes between units.
- Too small a technical room - a problem with the installation of a buffer or DHW.
- Installation of air conditioning "ready" - forging walls and unsightly troughs.
However, the above mistakes can be avoided if you have a plan from the very beginning. At Hymon Powered by Kajima, we are here to help you create and realize it.
How to prepare a single-family house step by step?
Here is a specific list of things to consider before pouring the foundations:
design:
- Roof without dormers and chimneys - perfect for photovoltaic installation.
- Technical room with access to the external wall.
- Space for the pump outdoor unit - preferably in the shade, with good airflow.
Installations:
- Reserve in the switchboard for photovoltaic installation, energy storage and heat pump.
- Underfloor heating (lower pump operating parameters).
- Pipe culverts between units, space for inverter and protection.
Air conditioning:
- Cans and culverts for indoor units (living room, bedroom).
- Technical channels inside the walls (instead of later forging).
Energy Storage:
- Dry, ventilated place - preferably in a garage or technical.
- Dedicated circuit and switchboard with protection.
It is also worth consulting an expert at this stage to check, Czy dom meets the conditions for obtaining funding from programs such as "My heat".
The future house starts with a wise plan
A modern single-family house is not only a nice shape and a good location, but above all reasonable decisions that will pay off in a few years.
Instead of fixing bugs, it is worth planning an energy system tailored to your needs: comfortable, economical and ready for the next decades.
At Hymon Powered by Kajima, we help private investors at every stage of construction: from design, through the selection of devices, to assembly and obtaining a subsidy.
