Simulations provide valuable information

Validate & Improve your design

We support architects, engineers, investors and contractors in the decision making process by providing quantifiable metrics that you can understand and trust.

By defining and analysing different scenarios, we are able to assist the planning team to optimize the:

Façade system / building envelope / building physics

Daylight design / natural ventilation / free-cooling

HVAC system design, sizing & control

Energy supply & storage systems

The optimum will be defined according to your needs. Typically it is determined by a mixture of indicators like investment/operational cost, energy efficiency, indoor comfort and daylighting.

Dynamic Simulations

We recommend the use of simulations in the early design process (schematic design and design development phase). This enables you to identify the best measures to be implemented early in the design process, reducing cost, time and a lot of worries during construction and commissioning.

We also support you in more advanced design phases by i.e. assisting the HVAC design engineers or BMS programmer in the definition and optimization of control strategies.

Our services do not end in the design stage, in fact we highly encourage our clients to use the simulation models and all the valuable information acquired in the planning stage for commissioning and even for operational optimization (“digital twin”)!

Energy concepts for Smart buildings & districts

Our area of expertise

Efficient & reliable systems

We develop innovative energy concepts for buildings & districts. We analyse the climatic conditions of the location and focus on taking the most out of on-site renewable resources. We analyse different scenarios and calculate the energy flows of the system.

Together with our client we look for the most suitable solution taking into account the cost-effectiveness & reliability of the system. We advise you on:

Renewable energy sources: solar, geothermal, air, water 

Energy generation systems: heat pumps, photovoltaic, solar & earth collector, etc. 

Energy delivery systems: thermal activation of building components, fan-coils, low temperature radiators, heat and moisture recovery

Energy storage systems: earth, water, ice, PCM, electrical

Control strategies and optimum temperature for the distribution networks of your building or district

Energy System Modelling

We use different energy modelling tools depending on the focus and goal of the project to provide quantifiable metrics:

For early design stages & architectural competitions 

Supporting the HVAC planning team with dynamic system information

Reviewing and providing an independent second opinion on existing concepts

By dynamically coupling the energy system with the building model we provide:

Very detailed knowledge about the future performance of your project

Optimize part load operation and system sizing

Valuable knowledge for the control engineers and facility management

Operational Optimization

Monitoring & Data Analytics

Put your building on our virtual test lab

Buildings are often not meeting their performance targets due to suboptimal commissioning procedures and lacking performance tracking. This results in high operational costs and uncomfortable indoor conditions.

We provide auditing services and long-term quality control to achieve & maintain the performance of your building.

Our approach is to support owners, facility management and system operators by providing knowledge out of the immense amount of aggregated sensor data

Through monitoring, data analytics and simulation with virtual twins we optimize the control of existing HVAC systems and ensure a profitable operation and comfortable conditions.

This will typically save you around 15% of energy costs and increase the comfort of your building

How does it work?

 By using your existing network of sensors and the data stored in your building management system we are able to detect suboptimal operation and give recommendations:

On improved control startegies, i.e. changing operational schedules, setpoints, heating curves, priorities

Malfunctioning or failing sensors or HVAC components

In case your data is not sufficient we can offer monitoring campaigns with our own sensors, or advise you on the extension of your monitoring system and data handling. 

As the most important thing is to constantly monitor and make sense of the aggregated data we provide custom reporting and visualisation routines that will keep your system performing well on the long run.
