A specialist division of Chrissantus Investment Limited

Green Environ Consultancy

Healthier indoor environments and more efficient buildings — indoor air quality, ventilation, energy efficiency and sustainability, advised with clarity.

Why it matters

The buildings we occupy shape how we feel

Most of us spend the majority of our time indoors, yet the air we breathe, the ventilation around us and the energy our buildings waste are rarely examined. Green Environ Consultancy exists to change that — with plain-language assessments and practical, prioritised recommendations.

As part of Chrissantus Investment Limited, we can also draw on the wider group — cleaning, property management and supplies — where a recommendation needs hands-on follow-through.

What we advise on

Four focus areas

Indoor air quality

Understanding what is actually in the air you breathe indoors — and what to do about it.

  • Walkthrough assessments of homes and workplaces
  • Monitoring of key indicators such as CO₂, humidity and particulates
  • Plain-language findings with prioritised recommendations

Ventilation

Helping air move the way it should — for comfort, health and moisture control.

  • Review of existing ventilation arrangements
  • Identification of problem areas: condensation, stuffiness, odours
  • Practical improvement options at different budgets

Building energy efficiency

Using less energy for the same comfort — better for running costs and for the planet.

  • Basic energy-use reviews for homes and commercial buildings
  • Identification of obvious waste: heating, cooling, lighting, equipment
  • A prioritised list of efficiency improvements

Environmental sustainability

Sensible first steps towards greener operation — without jargon or grand claims.

  • Practical sustainability guidance for households and small organisations
  • Waste, water and consumption quick-wins
  • A realistic, staged plan you can actually follow

The process

How a consultation works

Initial consultation

A conversation — by phone, video or in person — about the property, your concerns and what you want to achieve.

Site assessment & monitoring

Where useful, we visit and observe — and where appropriate, leave monitoring equipment to gather real data.

Findings & recommendations

You receive a written summary in plain language: what we found, what it means, and what we suggest — in priority order.

Implementation support

If you want help acting on the recommendations, we can coordinate — including drawing on other Chrissantus services.

Review & ongoing advice

We can re-check after changes are made and remain available for questions as seasons and usage change.

Describe your property and your concerns — stuffiness, damp, high bills, or simply wanting to understand your indoor environment better — and we will suggest the right starting point.
