Smarter Buildings: The healthy building

This month the publication ‘Program of Requirements for Healthy Offices 2018’ was published. In the introduction to the document, the striking question is: ‘What guarantees that the data tasks are good for health, comfort and productivity? and what is its importance?

It costs human life years
People spend 90% of their time inside, in the office, at home, at school or elsewhere. Nowadays we know that it can take numbers of years of our life’s when we spend our time in an unhealthy indoor climate. The World Health Organization (WHO) has developed a method that is defined as the Disability-Adjusted Life Year (DALY). DALYs are usually used to make decisions about health care. DALYs are also used to determine the efficiency of environmental policies in social cost-benefit analyzes. The DALYs can easily be translated into social costs, which consists of a description of the health damage of fine dust. These can be compared with the costs of environmental measures to reduce particulate matter concentrations. The amount of fine dust in buildings is barely measured in the current the situation, but the effect of fresh, clean and healthy buildings is huge.

Insure indoor environment
Wouter Truffino, Holland Proptech: ‘How cool would it be if you left the building at the end of the day more energetic and healthier than when you got there’. The WELL certificate has made its appearance. Insurers are considering insuring organizations and people on the indoor environment theme. It is obvious; healthy buildings are the future.

Measure and adjust
Also in the Smart Building project, the importance of health in buildings is recognized. From the publication PR Healthy Offices 2018, four indoor environmental themes are the most important: air, climate, light and sound.

Sensors to gain insight
A sensor has been developed in order to gain insight on the indoor environment of the pilots within the Smarter Buildings project.  From the theoretical specifications a sensor suitable for market introduction has been developed, the development of which is shown below.

 
Pre- Alpha                                                       Alpha
 

Beta                                                            Release candidate

In the past period the Beta version has already been tested in Smarter Buildings. The input obtained from the Beta Version has provided a lot of insight for the Release candidate version (see specifications below). In the coming period, these will be rolled out in the Smarter Buildings pilots in order to gain more insight on the indoor environment of these buildings and to determine how this can be optimized. For more information about this project, please contact Wilfred van der Plas from Simaxx or Jan Mink from VTEC L & S. The Smarter Buildings project receives co-funding from the OP Zuid program (Development Program South Netherlands). OP Zuid is a European subsidy program for the Southern Netherlands and uses funds from the European Regional Development Fund (ERDF). The spearheads of this program are innovation promotion – by promoting cross-overs with and between top clusters – and the transition to a low-carbon economy.



Smarter buildings project: Lower the service costs

How can you determine your savings? The most important thing is to determine the starting point and get insight of the current situation.
Technically that means that it’s necessary to have a clear description of the building (buildings year, acreage etc.) and the building bound installations to establish the saving possibilities.
When additional sensors are added at a later stage, optimalisations can be realized based on the data and insight.
By properly documenting the starting points, it becomes clealry which actions have led to savings.
The pilot project Smart Buildings is currently monitoring the energy meters en sensoring data to determine potential savings.
We will share this information with you through this message: what strikes us?

Benchmarking brings perspective to measured data
The measured data from the Smarter Buildings pilot location were compared to the CBS figures. The high gas consumption and the associated costs in the comparison is outstanding.
A second benchmark in which gas costs and HSE service costs have been examined has proven the same, namely 64% higher service costs! On the other hand, electricity consumption and costs are lower.

Electricity use
To get more insight on the use of energy, we use a heatmap. The heatmap is shown down below and gives insight in the use per hour of the electritymeter in periods per week. The Heatmap shows a nice electrity profile that meets the expectations: an office thats in use five days a week, from approximately 9 a.m. untill 7 p.m. The energy consumption of the building out of office hours is 25% compared to the peek hours, which also meets the expectations. Yet we do notice something remarkable: whats happens at night at 01.00 p.m. that makes the energy consumption twice the zero load?
Reason to understand where that comes from? Yes, because it can result in a small saving on the already ‘low’ energy use.


Table 1: Heatmap 

Gas usage
The use of gas is shown by using a Scatterplot. In this graph, the gas consumption is compared with the outside temperature and gives the following insights; you would expect that the colder it is outside, the harder the boiler burns and the more gas is burned. In the purple line in the Scatterplot, the spread of the gas consumption is large regardless of the outside temperature. In the red circle you can see that gas is also used for heating at higher outside temperatures. This is direct energy waste and a reduction in comfort. By optimizing the boiler (regulation), substantial savings are possible.


The numbers tell the truth
Establishing the starting points helps to show the savings but also to find the first quick wins in terms of savings. The so-called low-hanging fruit often results in a few simple adjustments which lead to savings in service costs and gas and electricity.

Smarter Building project: test phase

The emergence of the Internet of Things (IoT) has created new ways to improve the quality of the indoor climate and the energy efficiency of buildings. This reduces energy consumption and increases the productivity of users within a building. By placing sensors, air quality, CO2 level and energy consumption can be measured at room level. The collected data is converted into information, which helps building managers to gain insight on energy flows and determine in a well-founded manner which energy-saving measures give the best effect. Besides that, the sensors and meters give insight in the condition of the building and installations, which results in the possibility to perform more predictive maintenance.

Schootsestraat
The Smarter Buildings project (consisting of VTEC Lasers & Sensors and Simaxx software) has the following objective: ‘The realization of a Smart Building solution for new and existing (groups of) buildings in which building management and building functions are fully integrated, in which energy consumption is further reduced and in which residents are offered maximum comfort and support ‘.

For example, KRAGT has made its location on the Schootsestraat in Eindhoven available to test the Smarter Buildings concept in an operational environment. The building, a business collection building, is equipped with extra meters for water and energy and climate sensors; the ClearClimate sensor. The ClearClimate sensor aims to provide insight into the (current) climatic conditions of the building and to look for possible energy savings.

Sensors
The ClearClimate sensor is developed by VTEC, it gives the possibility to measure temperature, occupancy, humidity, CO2, volatile organic compounds and light with only one box (see picture on the left). The data from this sensor is translated by Simaxx into action-oriented information for building managers and users. The analytical rules within the Simaxx platform make it possible to determine the current climate in the building.

More sensors have already been installed in the past period. It concerns sensors to measure the water consumption and a fine dust sensor is added to the climate sensor to measure PM 2.5. This data will soon be visible on the Simaxx platform too. The next steps in this research will consist of the long-term measurement of the building data and testing, with the buildings manager,  the best way to feed back the information and which conclusions can be dwarn from the information. The ultimate goal is to identify the most efficient measures for energy and indoor climate improvements. In the following message we will provide more details about the measurements and the results.

Smarter Buildings project

The world is becoming increasingly interconnected. By 2020,  25 billion devices will be connected (wireless) to each other and the possibilities offered by this connection are endless. Smart Systems and Internet of Things (IoT) will be economic drivers with great social value in the upcoming years. IoT applications already have the potential to reduce the total energy consumption in modern office buildings by 50%. It is expected that the next generation IoT applications will further combine and integrate autonomous building functions and user tasks. Equipment that supports and facilitates our daily life by providing the daily processes and actions with information on which people and devices can take action.

Goal
The Smarter Buildings project (consisting of VTEC Lasers & Sensors and Simaxx software) has as objective: ‘The realization of a Smart Building solution for new and existing (groups of) buildings in which building management and building function are fully integrated, where energy consumption is further reduced and residents are offered maximum comfort and support’.

Two pilots
Smarter Buildings, in collaboration with KRAGT Stroom BV and the Smart Homes foundation, will test its innovations in two pilot projects. The first pilot is a multi-company building in Eindhoven in which the impact of Smart Buildings on the comfort and energy consumption is measured. The second pilot will take place in the smart house in Eindhoven and will see whether the data from Smarter Buildings can be used to develop applications that help single elderly people to live longer and safer independently at home.

Duurzamere Zuidas Amsterdam

Agreement for a more durable Zuidas (Amsterdam)

Buildings on Zuidas (Amsterdam) are already using 20% less energy than the average building in the Netherlands. This can however still be improved.

This is what the Green Business Club Zuidas, Hello Zuidas and the City Council of Amsterdam are writing in the Durability report Zuidas 2015 that was presented on 13th April. The companies and organisations that are situated here took many steps in 2015 to improve the durability of the area. New biking facilities were introduced, new durable office and living premises were finalised, heat and cold storage applications were installed and solar panels were installed.

In 2015 a large group of companies expresses their ambition to realise the most durable business and living environment of Europe in 2020. These ambitions are listed in the Ambition Statement GBC Zuidas 2015 that was signed by more than 25 different parties. Zuidas is the only developing location in the Netherlands that publishes yearly durability report.

Research from the Dutch ministry of Infrastructure and Environment in 2015 showed that buildings are responsible for 36 percent of the total CO2 emissions. And half of these are office buildings. The Amsterdam council demands high durability performance from investors: a new building must at least have a Breeam Excellent-label to get the go-ahead for Zuidas.

Most durability measures are however not demands from the authorities but are introduced from the companies themselves. The Edge, the building that amongst others houses Deloitte for example produces more energy than it uses. The Edge and the main office of ABN Amro recently received an important international durability price for their offices: ABN Amro the Breeam In-Use Award for existing office buildings and the Edge the Breeam Award for the most durable new office building.

Durability is very important for all councils in Twente and the Brede School received 40 percent of all the votes. In total 45 project were submitted.

The Brede School from Losser as the winner
This new school building has many durable features for energy, water and nature. This makes it the winner of this award. To be able to realise ambitions focussed on durable renovations and new buildings it very important assure durable achievements.

Gebouwen Nederland grootste milieuvervuilers

Buildings in the Netherlands are the largest polluters

You may not be expecting this but offices, shops and houses are the largest polluters in our country. Figures from the Energieonderzoek Centrum Nederland show that there are 8 million buildings in the Netherlands and that these are responsible for 36 percent of the all CO2 emissions of the country. Half of this figure comes from office buildings.

In order to be able to achieve the energy goals in the Netherlands it has been agreed that buildings should save 20% on energy by 2020. Pressure is increasing on the real estate business to improve the durability of their buildings. Simaxx play an important part in achieving this goal. By using the platform in office building a significant reduction of CO2 emission can already be achieved.
