Energy-efficient ventilation for home

Solar Smart AHU

QUALITY INDOOR CLIMATE

MINIMUM ENERGY COSTS

SMARTLY CONTROLLED AIR FLOWS

Implemented solutions

Challenge
High energy costs and uncomfortably warm office spaces.

Solution

We adapted the existing ventilation system to operate on demand, adding cooling with domestic water to ensure the building operates more energy efficiently. The result is a controlled and balanced indoor climate, which improves employee well-being and reduces energy costs. Energy savings reached up to 40% thanks to more efficient use of thermal energy (so-called district heating) and reduced use of air conditioners. The payback period of the investment is 2-3 years.

Challenge
There was no ventilation in the house.

Solution

We built a comprehensive smart and needs-based ventilation system with two air intakes – one air intake on the north side, the other on the south side through a solar air heating collector.

The temperature difference between the north and south air intakes is 30-40 degrees. CO2 conditions are ensured in an energy-efficient manner.

Challenge
The goal of the complete renovation was to achieve the most energy-efficient solution for the house's ventilation, heating, and cooling, using smart renewable energy solutions.

Solution

The complete solution combines air-to-water heat pumps and a smart ventilation control system, ensuring efficient energy use. In addition, the building produces electricity from solar energy, and the heat generated by the solar air heating system is directed to heating and domestic water heating. The result is minimal energy consumption for residents and a healthy indoor climate, which increases both comfort and energy efficiency.

Intelligently controlled airflows

Our innovative ventilation system is designed to maximize the use of solar energy to preheat the supply air. When creating the solution, we take into account the specifics of the building’s facade and location in relation to the weather maps to achieve the highest energy efficiency.

Two air intakes are used in the ventilation system:

The south-facing air intake supplies the system with preheated air, which is collected from the solar air heating collector or from under the solar panels.
The north-facing air intake ensures natural cooling.

The temperature difference between the north and south air intakes can reach up to 40 degrees, which reduces the need for additional energy. The entire system is controlled by modern automation, which optimizes work processes and ensures smooth operation.

Minimum energy costs

Unlike traditional ventilation solutions that require a lot of energy, the Solar Smart AHU is designed to use energy efficiently. The solution is based on the idea that the heating needs of the ventilation system are covered to the greatest extent possible with locally produced energy.

Solar air collectors and solar panels provide a preheater for the ventilation system under favorable conditions.
Effective heat recovery keeps additional energy consumption to a minimum.

As a result, electricity costs and, under favorable conditions, the building’s heating costs are reduced.

High-quality indoor climate

Our solutions ensure a healthy and comfortable indoor climate, which is important for both human well-being and the preservation of the building.

Humidity under control: Ventilation removes excess moisture from rooms, preventing mold and extending the life of building structures.
CO₂ level: The system is equipped with CO₂ sensors that ensure air quality in an energy-efficient manner.
Continuous monitoring and optimization: Automation ensures that the indoor climate remains stable in every season.

A high-quality indoor climate reduces health problems, increases productivity, and creates a pleasant environment for all building users.

Integration with existing solutions

The Solar Smart AHU is designed to blend into the building’s architecture and can be easily integrated with existing energy solutions.

Flexibility: The system can be combined with solar air heating collectors and PV panels, using the heat they produce to preheat ventilation.
Aesthetic design: The solution blends in with the building facade, maintaining architectural integrity.
Modernization: The existing ventilation system gains a new level of efficiency by adding Solar Smart AHU automation.

Our solution combines aesthetics, functionality and environmental friendliness, offering customers long-term benefits in the form of both energy savings and a high-quality indoor climate.

We develop and produce in Estonia with the aim of maximizing the use of solar energy. We measure our climate impact and reduce our CO₂ footprint.”

The main function of a solar air heating collector is to produce heat energy on site and stabilize the indoor climate of a building. It is particularly suitable for buildings with limited space for solar energy generating elements.

A solar air heating collector is mounted on the wall of a building and directs the heat collected from solar radiation directly into the ventilation system or rooms, reducing energy costs. This system is more efficient than PV panels in producing heat: to achieve the same efficiency, several PV panels would have to be installed.

The appearance of the collector can be customized to match the color of the building’s facade, matching the building’s architecture.

Wall mounting makes it space-saving and easy to integrate.

This solution is best suited for buildings where ventilation efficiency and energy cost reduction are a priority. Well suited for both residential and commercial premises, providing a healthy indoor climate and lower energy costs.

Directing excess heat to domestic water

Price from 4999€ for wall, 7299€ for roof

The main purpose of PV panels is to generate electricity, but the excess heat generated underneath them can be used for preheating and ventilation if necessary, if technically feasible.

This solution is suitable for buildings that have the option of installing PV panels on either the facade or roof and whose priority is to cover the building’s electricity consumption in an energy-efficient manner.
