Process energy in laboratories

The Danish Building and Property Agency will reduce process energy consumption in the laboratories of the universities. The Danish Building and Property Agency has already worked to reduce process energy consumption in fume cupboards. But there are many other technical installations, which result in great process energy consumption.

As a part of the work in the energy efficiency renovation strategy, the Danish Building and Property Agency has received funds to conduct an analysis of the potential for reducing process energy consumption.

Example of the Danish Building and Property Agency's requirements for reduction of process energy

In the Danish Building and Property Agency's project with expanding Panum, the starting point has been Building Regulations 2008 and requirements for the fulfilment of low energy class 1, which corresponds to a 50% reduction in the general energy framework of BR08. At the same time, the Danish Building and Property Agency has made demands on the advisors to make plans with the goal to reduce process energy by up to 50% of the consumption that technical equipment and installations are otherwise known to contribute with.

The internal load, e.g. the users' energy consuming equipment such as PC', servers, etc., are not included in the work of the planners and will remain unchanged. Among other things, the requirement has resulted in ventilation solutions being analysed extra carefully and that users have been challenged in relation to the actual need for the number of fume cupboards.

The advisors have subsequently investigated the possibility of increasing the energy framework further to the 2015 or 2020 level. Here they encountered the dilemma that energy optimisation of the building's climate envelope increased the need for process ventilation and thus the building's total energy consumption. Panum will be built in energy class 2015.

Example of the market impact - fume cupboard invitation to tender

The Danish Building and Property Agency has conducted an invitation to tender for fume cupboards across the property portfolio, which combined will shape the market standard and reduce energy consumption by up to 40% per fume cupboard. Energy consumption of fume cupboards make up a major part of the process energy in laboratories and has not improved over the past 30 years. In order to optimise to best effect, the invitation to tender for fume cupboards also means that the supplier is responsible for both equipment and technology as opposed to the past, where the contract was divided.
