Textbook example of Energy Neutral Construction
How homes and buildings can make a significant contribution to CO2 reduction
We were guests of the Christiaan Huygens College, a very modern designed building that is completely energy - neutral, even having facilities to supply energy to the surrounding neighbourhood.
The building was thus a concrete example of a solution in a meeting that focused on the opportunities offered by the built environment to get within the CO2 emission reduction requirements to which we in Europe have committed for the year 2050.
As a red line through the energy programme, the meeting opened with the study made in Region South of the total energy consumption in the Netherlands and the associated CO2 emissions. With input from the kick-off session on 6 May, it became clear that limiting the use of fossil hydrocarbons from oil, gas and coal in Europe will have the effect of reducing refining, storage, transhipment and transit in the Botlek area by at least 80%. An important contribution to the Dutch economy and trading position will thus fall away. Vital to take action here towards developing alternatives. It was noted that the energy consumption of homes now still causes about 1/3 of Dutch CO2 emissions and energy-neutral construction would make a major contribution to achieving the standard.

Joost Wentink, our vice president, presented in a clear speech that there is a lot of energy to be saved and thus CO2 reduction to be achieved with especially reducing losses. He brought out that this can be stimulated with the integrated approach in assessing insulation and energy use in buildings. Not the current approach of looking at insulation, glazing, heating or ventilation in isolation, but a measure of the whole. By setting requirements for energy consumption for sales and government measures, the market will also start to focus on offering integral approaches to energy measures in construction. One yardstick for integral energy consumption is the system of energy - labelling.

Ivo Opstelten systematically guided us through all options on how to achieve these savings. Always testing how and in which buildings the options of insulation, heat and cold storage or solar panels made sense. Always with a view to costs and practical consequences in terms of construction and time. He told us that monuments in the heart of Amsterdam might never become energy-neutral, but that new buildings could certainly also produce energy. An energy-neutral built environment is certainly possible. The price of some 400 Billion by 2050 requires an acute start to meet the goal. Through targeted regulation and tax incentives, the market will certainly be incentivised to fill in a lot on its own. The engineer's job is to participate in this and also to identify the additional technology needed and initiate development towards it. It is up to policymakers to make those needed developments happen with consistently implemented long-term policies and measures.

The Christiaan Huygens College as a practical example of energy-neutral construction was explained by Ruud Reiners of Volantis. Along the history of preparations to construction and in construction, it became clear that a new approach to building is required. Starting from the intention, it will first be necessary to seriously seek which construction or installation company is willing to apply the new techniques in the work. For the roof as a heat exchanger, techniques are known but with manufacturers it is searching until carrier, exchanger and roof cover form a whole and are affordable too. Obtaining permits for the cold/heat storage required extra time. Obtaining support to place this very modern building in the middle of an old traditionally built neighbourhood also required a lot of extra consultation with local residents.

Finally, the user himself speaks. With due pride, the headmaster of the College, Martin van den Berg, points to the design both outside and inside. The pupils of this VMBO college are also clearly proud to follow their education in the most modern and very luxurious building. Advantages in use are the very pleasant and constant living climate in the building. Humidity, lighting, temperature, radiant heat from the sun on the windows and air conditioning are all so integrally under control that everyone feels comfortable. Even clearly noticeable in students' study results and their attention even in the last class hours of the day. In addition, of course, there is the benefit of no energy bills. Martin van en Berg could not yet answer whether maintenance costs would be higher or lower than with conventional construction and whether the absence of energy bills would outweigh maintenance costs. For now, he was extremely content and led us enthusiastically through the central rooms of the building to conclude this meeting with drinks.
There were 52 participants in the symposium, including 13 non-members of KIVI NIRIA.
The programme we followed can of course be revisited on the activity pages on 28 August 2013, you can find the pageheresee.
This symposium is part of six meetings on energy management and CO2 reduction. You can find information about the total programme and the announcement of the 4 more meetings can be found here find it.
Description
Due to illness of both speakers, this activity cannot take place.
The Christiaan Huygens College has the first energy-neutral school building in the Netherlands.
This evening will discuss how the building came about and the combination of sustainable energy measures used.
Among other things, the school has an Energy Roof+ that generates both heat and electricity and a heat pump system with thermal storage. A heat network combines supply and demand from the school building, adjacent sports hall and future residential area. This combination not only reduces energy consumption, but also the amount of installed power, which together leads to significant cost savings. Air treatment, underfloor heating and cooling and the well-insulated facade ensure a pleasant indoor climate. Thus, the architecturally exceptional school provides a productive and stimulating environment for both pupils and staff. For the progressive combination of technologies and the international attention generated by the sustainable school building, the building was awarded the OnTroerendGoedAward.
