Owner approach of sustainability

Landstinget in Värmland has a long traditon of acting consciously to choosing and regulate the “best” enviromentaly friendly products in construction. In its buildings Landstinget does not wish to build in material that it subsequently may have to sanitize or retrofit later or which might cause illness. By controlling the selection of materials and managing output, risks and problems can be minimized reducing later stage impact to the environment.

All products used in construction must be checked against Landstingsfastigheter’s overall environmental guidelines through the chemical database, SundaHus. The database, besides containing classifications of different chemicals by current applicable law and recognition, contains a filter which can sort out chemicals Landstingsfasigheter in Värmland wishes to reduce or phase out entirely according to its environmental guidelines. In the guidelines there are more then 750 different chemicals banned. The method provides progressive companies a list of chemicals to avoid as they aim for a sustainable future.

Architectural description

In the spring of 2013 the new neonatal department of the local Central Hospital opened. Premature babies and sick newborns are cared for here. During construction only materials that met Landstinget’s(the County Council’s) environmental requirements were chosen.

What are the effects in the form of reduced unwanted chemicals incidence reaches county real estate in Varmland through its environmentally conscious work in construction projects and how much is the increase in expenditure which this entails?

The current project concerns mainly conversion of an existing building. The total cost of the building department with environmental overtones is 0.33% higher than it otherwise would have been. The conscious choice of materials has reduced the amount of phthalates with 800 kg and the amount of PVC with more than 1,600 kg. The selected materials have not reduced the quality or function in relation to any other materials.

If you had to do it again?

Modify the medical equipment so that it does´t need to be any static dissipative
floors in the building.

Building users opinion

The people working are very satisfyed, they have had a lot of visits from other hospitals. The goal have been that the newborn child shall not be separated from parents during the hospital stay and all parents should be offered a room directly adjacent to the point of care and that
no contagion of multiresistant bacteria shall be possible. Due to the architecture it is possible for the parent to stay close and also to get a room close to the outside and the inside of the clinic.

Indoor Air quality

All products used in construction must be checked against Landstingsfastigheter’s overall environmental guidelines through the chemical database, SundaHus. Additionally this database, besides containing classifications of different chemicals by current applicable law and recognition, contains a filter which can sort out those chemicals Landstingsfasigheter in Värmland wishes to reduce or phase out entirely according to its environmental guidelines.
Some of the demands that Landstingsfastigheter have are
* Limitation of VOC (Volatile Organic Compounds)
* Limitations / restricted use only after demands / of PVC
* Limitations of a bunch of chemical substances that have or are suspected to have negative effects (The County Council work based on the precautionary principle and research on chemicals and exposure.)

Health & Comfort

Health & comfort : The goal has been that the newborn child shall not be separated from parents during the hospital stay. All parents should be offered room directly adjacent to the point of care and that
no contagion of multiresistant bacteria shall bee posible. Due to the corridor utside the rooms it is possible get a relation between indoor and outdoor environment and the variation of the nature´s cycles. The indoor thermal comfort are extremely important in this care.

Acoustic comfort : Acoustic comfort are calculated in the project SS25268:2007 klass C.

Product

Outcome of environmentally conscious material choices at a neonatal department in the main hospital i Karlstad

Product category :

Landstinget in Värmland has long acted consciously to choose and regulate the “best” environmentally friendly products in construction. In its buildings Landstinget does not wish to build in material which it subsequently may have to sanitize or retrofit later or which might cause illness. By controlling the selec- tion of materials and managing output, risks and pro- blems can be minimized reducing later stage impact to the environment.
What impact in terms of reduced unwanted chemi- cal presence does Landstingsfasigheter in Värmland achieve through their work and at what increased expenditure?

The difference between building with environmental or without environmental requirements but with the same functional requirements is in the present case estimated to 201249 SEK. The total cost for the con- struction was 59,229 thousand SEK, the subsequent increase in building environmentally consciously was 0.33% of the total budget, excluding equipment for this project. At the sime time there was a reduction of through active environmetal choices approximately 800 kg (787-915 kg) of phthalates have not been released and that the benefit to the environment is not insignificant. In ad- dition, we know that we did not have to use 1598kg PVC plastic by choosing a different superior plastic.

All premature infants in care in the region will directly benefit through reduced exposure to chemicals at the same time as the entrepreneurs will learn to think on the environment in other projects.
