Energy efficiency projects
Cut your property’s purchased energy and running costs to a minimum with an energy efficiency project. Granlund’s energy experts make sure the investment pays off and the systems perform as they should. We support real estate owners and operators with the full range of energy efficiency services, from single studies to full turnkey delivery.
Energy efficiency projects are a profitable investment
Well-planned and carefully executed energy efficiency projects are rewarding investments. As your reliance on purchased energy falls, so does the financial impact of energy price fluctuations.
Energy efficiency projects raise the value of your properties, lower running costs, cut emissions and improve indoor conditions and occupant satisfaction.
Managing the big picture
Granlund offers some of the broadest energy expertise in the field of real estate energy efficiency. Our service quality comes from combining knowledge across disciplines: alongside energy specialists, you’ll find designers, construction management professionals and experts in commissioning and performance assurance, all under one roof.
Real results in energy efficiency come from managing the whole system, not from a single, isolated fix. That’s why we always look at a property and its energy systems together. We use tools such as AI-based energy mapping and multi-objective optimisation to compare options and identify the best solution for each property.

TURNKEY DELIVERY
We deliver energy efficiency projects on a turnkey basis, taking responsibility for the survey, design and construction supervision. After handover, we ensure that the finished solution meets its targets.
SINGLE ASSIGNMENTS
We also take on individual assignments based on what you need, from surveys and calculations to site supervision.
We start by examining the property through its automation system, checking system performance and accuracy of data reported. This includes temperature and control settings.
Next, we review the rest of the property’s technical systems: heat pumps, air handling units, heat distribution and the spaces people actually use. We check that the technical solutions work in practice and that air distribution, heating and cooling are set up and performing correctly.
We then assess potential improvements to performance, with a quick analysis of the improvement potential and an estimate of costs and benefits.
Finally, we present the results to you and agree the next step together, including an assessment on whether more detailed studies or further calculations are needed. This stage is also known as the preliminary design phase.
During the project planning and technical design phases, we define the required measures and the best technical solutions. We produce a more detailed cost estimate along with more precise projections of savings and impact.
We put major equipment purchases and installation work out to tender to get a reliable, cost effective price estimate.
We compile everything together and present it clearly. Where useful, several options at different scopes can be presented so you can choose the solution that fits best.
We can take on project management for energy efficiency projects across contract types, using a range of delivery models including EPC and EPCM. Where agreed, projects can be delivered with a savings guarantee.
Under the EPC model (Engineering, Procurement and Construction), Granlund takes full responsibility for the energy efficiency project from start to finish.
We handle design, procurement, construction and the schedule, for an agreed total price.
Under EPC, the energy efficiency measures are structured so the resulting savings fund the project itself.
For you, this means a clear division of responsibility and a working energy solution delivered on a turnkey basis.
Under the EPCM model (Engineering, Procurement, Construction Management), we act as your expert and project management partner. We handle the project’s design, procurement and construction management.
Under EPCM, we help you choose strongest solution both the technically and financially, tender the contracts and make sure the project is delivered as planned, on schedule and cost effectively.
EPCM is particularly suitable to customers that require more transparency, flexibility and involvement in decisions, along with the ability to compare different options and delivery methods.
After installation, we run performance tests to confirm the new systems work as they should. Before that, we review the design documents and check that what’s been built matches the plans. We also confirm that controls and settings operate as intended.
We check that the contractor’s documentation has been completed correctly and that the contractor has carried out its own inspections properly.
During the warranty period and beyond, we verify, adjust and monitor system performance. We make sure the systems run steadily, without fluctuation, and that equipment operate optimally.
Our aim is for the target conditions to be met as planned. We use AI to help spot deviations early and confirm the systems are working correctly.
As your reliance on purchased energy falls, so does the financial impact of energy price fluctuations.
The biggest savings come from energy recycling
Energy recycling is the single biggest opportunity to save money and energy.
Effective energy recycling calls for broad expertise across heating, ventilation, cooling, automation and electrical systems.
Beyond that, we understand how these systems depend on each other, which is what makes the difference between a solution that works and one that doesn’t.
Examples of profitable energy recycling solutions
Cooling equipment heat recovery
This matters most in retail, but it also suits cold storage facilities and any commercial or industrial site that needs simultaneous cooling and heating.
The condenser heat from a cooling unit is recovered using a heat pump and stored in a tank, from where it can be fed into the heating network. The system needs careful sizing and optimisation to run reliably and efficiently.
Extract air heat recovery
Extract air heat recovery suits offices, commercial premises and industry, in practice any site with ventilation.
Heat is recovered from ventilation extract air, typically with a heat recovery coil.
In industrial settings, extract air temperatures can be high, allowing for the heat to be used for heating domestic water, pre-heating processes or heating spaces.
Cooling heat recovery
Whenever water chillers or industrial cooling processes are being renewed, it is always worth assessing their heat recovery potential. The applications are the same as for extract air heat recovery.
Where spaces or processes need cooling and heating at the same time, a heat pump is a highly effective solution. No heat is wasted; instead, it is recovered and put to use.
Energy efficiency has far-reaching impact
Energy efficiency projects raise a property’s value and rental yield, both in the short and the long term. Demand and attractiveness grow as a building’s energy rating improves, indoor conditions get better and running costs fall.
An energy efficiency project can also be designed to support a property owner’s sustainability goals, such as EU taxonomy alignment or emissions reduction.
