Foundation
A monolithic reinforced-concrete slab without a basement, set on prepared ground.
Construction and engineering
How the home is built and performs throughout the year
The home combines a monolithic reinforced-concrete slab, factory-insulated Consolis panels, a heat pump, water-based underfloor heating and mechanical heat recovery ventilation.
Every solution can be verified in the technical documentation and equipment specification.

The home as a system
From the foundation to the ventilation system
Performance is not determined by a single piece of equipment. It depends on the prepared ground, water management, wall structure, insulation, windows, heating and air exchange working together.
02
Water management
The site includes drainage and a land-reclamation network to remove excess moisture.
03
Walls and floor slabs
Factory-made three-layer wall panels and reinforced-concrete floor slabs by Consolis.
04
Roof and windows
An insulated flat roof and ARTEVO windows with triple Low-E glazing.
05
Heating
A Mitsubishi Electric Ecodan heat pump and water-based underfloor heating on both floors.
06
Ventilation
A central Mitsubishi Electric Lossnay heat recovery ventilation system.
Structure
The home begins with properly prepared ground
The home is built on a monolithic reinforced-concrete slab. Beneath it is a prepared base incorporating GEO PES 300 geotextile and a layer of 10–20 mm expanded clay aggregate.
The development includes a drainage system, with a land-reclamation network running alongside the plots. Together, these measures help direct surface water and ground moisture away from the built area.
The foundation slab distributes loads across the full footprint. Service entry points and construction joints are protected against moisture ingress.
Thermal envelope
Insulation is integral to the structure
The external walls use three-layer reinforced-concrete panels by Consolis. The insulation is factory-installed as an integral part of each finished panel.
The structural elements are joined using the Peikko system. Intermediate floor slabs and the roof deck are made from Consolis reinforced-concrete panels.
The flat roof build-up includes a 1.5 mm Rhenofol CV PVC membrane, ROCKWOOL insulation and a TENAPORS EPS-100 layer.
The home is fitted with ARTEVO windows featuring triple Low-E glazing and Roto NX hardware. The calculated thermal transmittance of individual window assemblies is Uw 0.71–0.78 W/m²·K.
Heating
Heat pump and underfloor heating on both floors
The primary heat source is a Mitsubishi Electric Ecodan air-to-water heat pump, supplying the water-based underfloor heating installed on both floors.
Heating circuits are controlled separately, allowing temperatures to be adjusted for different rooms.

Indoor climate
Continuous air exchange with heat recovery
The central Mitsubishi Electric Lossnay system supplies fresh air and extracts stale air. Its heat exchanger transfers part of the heat from outgoing to incoming air, reducing losses during the heating season.
The heat exchanger's rated efficiency is 85–90%, depending on operating mode. The building's energy-certificate calculation uses a figure of 83%.
Ventilation
Mitsubishi Electric Lossnay VL-350CZPVU-R-EAirflow — 96–320 m³/h
Sound level — 15–35 dB
Air conditioning
Services are provided for the later installation of air-conditioning units. The owner selects the equipment separately.
Mains utilities
The home is connected to the municipal water and sewerage networks. Water consumption is metered individually.
Electric vehicle
A dedicated electrical supply is provided at the parking space for a future EV charging point.
Design-stage calculation
Class A performance confirmed by the energy certificate
A provisional design-stage energy certificate has been prepared for the building at Cīniju iela 9. The calculation assigns the building Energy Performance Class A.
