Decarbonisation & NET ZERO Solutions for Buildings

Modern open-plan office with white desks, beige chairs, and green plants in wooden planters, with large windows and an exposed ceiling.

Hollen+ delivers tailored, asset-led decarbonisation & NET ZERO pathways.

Our pathways are aligned with the natural lifecycle of the building to minimise costs and improve returns, thereby adding the greatest possible value.

We assess each project individually and create solutions which achieve low-energy buildings and optimise occupant comfort. This allows for a holistic approach to environmental design.

Bright indoor space with large glass ceiling and walls, wooden herringbone floor, modern chairs and tables, hanging plants, and a white counter in the background.

Our approach works with the natural life-cycle of the building and it’s systems, to minimise cost and disruption. Our approach takes into account existing PPMs, service charge recoverability, and the deliverability of works.

We create tailored action plans to use opportune times, such as lease expiries, or system replacements, to make the greatest possible impact.
