Save your time and help your clients to find energy solutions that make sense
Five things Apex Heat App does for you right now.
Energy grant calculated in moments
Determine both eligibility and the grant amount in one go – and meet housing companies’ demand right away.
Baseline data retrieved automatically
Numerous data sources – from up-to-date energy prices to investment costs – speed up the calculation and turn a potential review into minutes of work.
An existing certificate read by machine
Import an old energy performance certificate and the software extracts the baseline data from it. A new certificate or energy project follows in no time.
An official energy performance certificate without manual work
The software produces the recommendations and proposed measures for improving energy efficiency automatically.
An IFC model straight into the calculation
Import an IFC model for precise planning. Coming soon: create the model yourself from structural drawings.
Comprehensive scope from investment calculation to E-number simulation
The software analyzes heating solutions, ventilation and heat recovery, cooling, waste heat utilization, solar power and passive energy efficiency such as additional insulation.
Alongside life-cycle calculation, the software analyzes how each measure affects the E-number, identifying the ways to improve the building’s energy class.
Questions about Apex Heat
Direct answers to the questions we are asked first.
What is Apex Heat?
A Finnish software company founded in 2021 whose Apex Heat App is calculation software for energy consultants. The company, the product, the users and what Apex Heat does not do.
Why can the calculation be trusted?
Heat losses from the building regulations' U-values, energy priced for every hour, measured consumption correcting the model and every assumption visible to the user. Also what the calculation does not know.
How easy is Apex Heat App to use?
The first calculation starts from an address. What data is needed, how estimates and your own data work together and what the software produces.
Does Apex Heat produce official energy performance certificates?
Not directly. Apex Heat App is software for producing certificates, used by qualified authors, and it shows at the same time which investments improve the energy class most profitably.
How is an investment's profitability calculated?
What a heat pump, added insulation and solar power cost and save, and how net present value and the discount rate decide the recommendation.
