Building Energy Consultancy and Expert Services

Efficient Solutions for New Buildings and Renovation Projects

Today, energy efficiency is no longer solely an environmental consideration — it is equally important from both economic and comfort perspectives. When planning a new building or renovation project, neglecting energy-performance aspects can lead to high operating costs, uncomfortable indoor conditions, and premature structural issues over the long term.

The purpose of building energy consultancy and expert advisory services is to ensure that every investment achieves the best possible energy performance, long-term value, and optimized operational costs.

How Can Building Energy Consultancy Help?

Pre-Design Analysis – Evaluation of site conditions, orientation, development potential, and environmental influences before the design process begins.
Energy Analysis of Construction Assemblies and Details – Assessment of thermal bridges, wall assemblies, windows, shading systems, and critical construction details.
Energy Performance Calculations – PHPP calculations and thermal bridge simulations providing an accurate prediction of the building’s expected performance.
Renovation Strategies – Development of energy-efficiency improvement concepts for existing buildings and retrofit projects.
Optimization of Building Systems – Energy-conscious design of heating, cooling, ventilation, and domestic hot water systems.

Why Is Detailed Energy Planning Essential?

Predictable Performance – Accurate calculations allow the expected energy demand and comfort level of the building to be determined in advance.
Lower Operating Costs – A well-designed building consumes significantly less energy, resulting in substantial long-term savings.
Sustainability – Modern, energy-conscious solutions reduce environmental impact and improve long-term efficiency.
Long-Term Value – Energy-efficient buildings remain more competitive and valuable over time.

Frequently Asked Questions

In what situations is it advisable to involve a building energy consultant?

For renovation projects, to identify the most effective energy-saving measures; for new buildings, to ensure long-term energy efficiency; and in cases where comfort issues, high energy costs, mould growth, or thermal bridges occur.

How much energy savings can be achieved through a well-designed renovation?

Depending on the original condition of the building, heating and cooling energy demand can be reduced by as much as 60–90%.

When should energy planning begin during a project?

The earlier, the better — ideally already during the initial concept development phase.
