Sustainable solutions

We'll go the extra mile to create sustainable solutions with a good indoor climate, when we advice clients and design buildings, systems and installations

In the planning and design of new buildings, installations, systems and infrastructure plus retrofits, Balslev does not only take into account today’s requirements. We stretch ourselves to ensure that the design contains the necessary flexibility to meet future demands which undoubtedly will be increased from political level, e.g concerning:

  • Sustainability
  • Energy effectiveness including energy recovery and recycling
  • Environmentally hazardeous or poisonous substances
  • Recyclablility at the end of service/lifetime.

Industrial and administration buildings plus public institutions consume vast amounts of energy. And employees and others need comfortable and healthy surroundings in order to maintain a safe and effective working environment with a comfortable indoor climate. This results in significant costs associated with lightingventilationheating and cooling – particulary if the systems are redundant energy absorbers or are incorrectly adjusted to the actual needs. In any project we therefore always consider energy optimisation just as we, whenever possible, recommend low energy solutions. And when we carry out energy labelling, we typically identify opportunities for significant savings – time and time again.

Intelligent solutions for low energy consumption and less COemissions

Through the intelligent application of present and future technologies there are numerous possibilities to meet the agreed requirements while at the same time reduce the costs for the expensive and increasingly scarce energy resources – not to mention reducing CO2 emissions.

One way to achieve these goals is to apply intelligent building management systems, which control and adjust the use of light, heating, ventilation etc. according to the actual needs – no more no less – with the help of e.g. daylight and movement censors.

Low energy solutions

We design low energy solutions for new buildings, retrofits, industrial plants, hospital installations etc.

At Balslev we consistently seek to recommend our clients the most optimal energy solutions. Low energy solutions designed by our engineers minimise energy consumption in buildings, plants and systems, and are usually based on well known, used and proven technology.

We have successfully designed a wide variety of low energy solutions for different application areas e.g.:

  • Optimisation of building envelope
  • Lighting
  • Plumbing systems
  • Heat pump systems
  • Heating, ventilation, air conditioning and cooling (HVAC) systems
  • Boiler plants
  • Central cooling plants.
Passive houses

To be able to advise our customers on the optimum solution, we strongly recommend to involve us earliest possible in the design phase. This has enabled us to deliver successful projects e.g. in the construction of passive houses, low energy houses and other low energy buildings.

A certified passive house meets several requirements with regards to e.g. maximum total energy consumption for heating, utility water and power, plus air tightness, according to the common European standard.

Energy savings

We also examine existing buildings and installations to provide our customers with an overview of the energy saving potential, e.g. in connection with energy labelling of buildings. As a basis for the client's decision making, we also conduct feasibility studies to estimate the pay back time for a particular energy optimisation solution.

CO2-neutral buildings

We can also design a new building and its installations like power supply, heating, lighting and cooling in a way so that its total CO2 balance remains neutral throughout its entire lifetime. We achieve this by chosing innovative solutions characterised by:

  • the lowest possible energy consumption
  • energy sources without any CO2 emission e.g. sun, wind and geothermal heat
  • heat recovery, ground water cooling etc.

The new head quarters of the company Widex is example of a CO2-neutral building.

Mandatory energy labelling and energy savings

In Denmark energy labelling is mandatory for all buildings for sale or rent plus for buildings of >1.000 m2 (every 5. year).

In addition, owners of public buildings are obligated to implement energy savings showing a repayment time of < 5 years.

Indoor Climate

A pleasant indoor climate is one of the requirements we focus on in projects related to construction and industrial plants. We can also help solve problems with poor indoor climate in existing buildings.

Poor indoor climate causes a long list of discomforts and can have a huge impact on people's health, work efficiency, learning ability and general well-being. People are different and react differently to impact from their surroundings. Some people are especially sensitive to certain conditions, whereas others react to completely different ones. For example, some people are particularly bothered by dust, while others are more affected by the room temperature.

Good indoor climate – a part of good consulting and design

When Balslev is in charge of the design of new constructions, refurbishments, industrial plants etc. our specialists seek to recommend solutions that will ensure a good indoor climate.

Analysis of indoor climate and improvement proposals

We have long experience in identifying indoor climate problems and present solutions to improve or eliminate such problems. We analyse and conduct a thorough survey of the affected buildings and in particular their use. As a next step, we measure a number of aspects related to the indoor climate:

  • Temperature (air and surface)
  • Air humidity, air velocity and air change
  • Noise levels
  • Amounts of articifial light and sunlight
  • Particle concentration
  • Outdoor air quality

Depending on the nature of the identified indoor climate problems, measurements are taken either over a few days or we set up equipment to measure selected climate conditions over a longer period of time. When we have completed our analyses and assessed the result, the client receives our report with specific solution proposals on how to achieve an optimum indoor climate.

Typical sectors
  • Public institutions
  • Business enterprises
  • Hospitals
What is poor indoor climate?

Most people notice when the indoor climate is unpleasant. But it can be quite tricky to define the actual problem. A poor indoor climate can manifest itself in many ways, but usually several of these symptoms occur:

  • Nose and eye irritations
  • Dry mucous membranes
  • Coughing
  • Wheezing breath
  • Difficulty in concentrating
  • Headaches
  • Fatigue
