New feature on!

Our Greenroof & Greenwall Directory Company of the Week is an exclusive benefit for companies listed in our Directory, highlighting their business to our audience of stakeholders, professionals, and decision makers:

GCW-Jakob-013015Jakob Rope Systems is a worldwide leader in manufacturing custom-made stainless steel wire rope, nets, rods, fasteners, and fittings.

Jakob-logoJakob has been providing design solutions and products for over 100 years in more than 55 countries.

Green facades are appealing, ecologically sensible, and useful. The latest insights on climbing plants, combined with tastefully designed and technically sophisticated training systems, open a treasure chest of greening variations and styles.

Jakob’s green solutions can be used to create a pleasant atmosphere, regulate interior temperature, and protect building facades. The product line includes Spacer and Wire Rope, Trellis Systems, Column Greening, Greening Barrier, Assembly Aids, and Webnet/spacers. Jakob uses AISI 316 high-grade stainless steel, and therefore will not rust.

CTBUH-IIT Team Wins Grant for Green Wall Façade Research

As most of us know, placing climbing plants on building façades is an effective way to reduce building energy consumption, mitigate the urban heat island effect and create natural habitat areas in cities.  These green walls lower heat transfer by reducing the façade’s exposure to solar radiation and wind, cutting the façade  surface temperature and providing extra facade insulation.

A collaborative team of researchers from the Illinois Institute of Technology College of Architecture and the Council on Tall Buildings and Urban Habitat (CTBUH) is conducting a research project evaluating the effect of green walls on building façade thermal performance and building energy savings.  The research was funded by a seed grant from the Wanger Institute for Sustainable Energy Research (WISER).

This year-long project is focused on developing a model to predict the effective thermal resistance of a plant layer placed on the façade.  A sensitivity analysis will determine which plants have the highest effect on the façades’ thermal resistance in different weather parameters.  The study also examines the importance of facade orientation, façade material, and climate zone.

To confirm the model’s predictions, the team has conducted an experiment measuring the thermal performance of the ivy-covered façade of Siegel Hall building at the Illinois Institute of Technology ion Chicago, which was designed by famed modernist architect Mies van der Rohe.  Future steps include calculating the average annual thermal resistance of the plant layer based on a combination of the selected parameters and façade orientations.

Additionally, an annual energy simulation will be conducted for a building model with a plant-covered façade to define building energy savings.  The simulation results will be used to form recommendations for building designers to lower building energy consumption through the use of green walls.

We will keep you posted on our progress.
