How we think about measures
Retrov8 USA LLC doesn’t just look at individual products – we focus on how different measures work together in a whole-house plan. That means:
- Checking that building envelope upgrades and HVAC design are aligned
- Making sure ventilation and moisture management aren’t an afterthought
- Designing with comfort, running costs and carbon in mind
Below are the main technical areas we regularly work with.
Insulation & air sealing
Improving the building envelope is often the most cost‑effective way to reduce energy use and improve comfort.
- Attic/loft insulation, floor insulation and wall insulation (where appropriate)
- Air sealing of key leakage points – attics, rim joists, penetrations and basements/crawlspaces
- Details to avoid common issues such as thermal bridging and condensation risks
- Coordination with ventilation strategies so indoor air quality is maintained or improved
Ventilation & indoor air quality
As homes become tighter, controlled ventilation becomes more important.
- Extraction for bathrooms, kitchens and other moisture‑producing areas
- Whole‑house ventilation options where appropriate
- Coordination with air sealing and insulation plans
- Simple, practical guidance for occupants on using new systems
Heat pumps & HVAC systems
Heat pumps and high‑efficiency HVAC systems can deliver excellent comfort and lower emissions when they’re correctly sized and installed.
- Room‑by‑room load calculations and system sizing
- Ducted, ductless and hybrid system concepts
- Emitter checks (ductwork, radiators, fan coils, indoor heads) for capacity and distribution
- Controls and setback strategies that match how the home is actually used
Solar PV & battery storage
Solar photovoltaics (PV), with or without battery storage, can help reduce reliance on grid electricity and support electrification.
- High‑level assessment of potential generation and interaction with heat pumps and other loads
- Discussion of orientation, shading and roof suitability
- Basic export and self‑consumption considerations (exact rate assumptions should always be confirmed with your utility)
- Coordination with broader electrification plans so systems are sized sensibly
Controls, monitoring & optimisation
Smart controls can make it easier to run an efficient, comfortable home – but only if they’re set up correctly.
- Selection and high‑level configuration of thermostats, zoning and scheduling
- Guidance on using manufacturer and third‑party apps
- Recommendations on simple monitoring approaches (for example, tracking energy use or key temperatures)
- Checks that controls strategies match the capabilities of the installed equipment
