Webinar : facilitate M&V in compliance with IPMVP

EPCs, ISO 50001, white certificates, or simply a request of clients: the reasons to Measure & Verify savings precisely and in line with IPMVP guidelines are many and energy managers need more and more to provide guarantees and to prove ROI.

During this webinar Denis Tanguay, the CEO of EVO, will share with you the latest updates on M&V. We will also exchange on the most common difficulties encountered by energy managers when running M&V projects and the solutions to simplify the process and to decrease the costs linked to it.

Speakers

Denis Tanguay, CEO at EVO

Matthias Zuliani, energy engineer, CMVP and EPC facilitator at Ingenium

Oguz Kiranlar, energy engineer and product manager at Energis

DATE: June 4th at 4 pm CET (9 am Quebec time)

Webinar: ensure healthy buildings during and after COVID-19

Monitoring indoor air quality in real time gives the right insights to maintain healthy conditions

Indoor Air quality is important and regulated by law. In a former article we already mentioned how in Belgium, a federal law entered into force last year to regulate indoor air quality standards. However, the current situation, is making it even more critical to be able to monitor and act upon it in order to guarantee healthy environments.

Just a few days ago, the 226 residents of a Quebec nursing home were all contaminated with Covid-19. The virus was present in the air and was found everywhere in the building. How did that happen? The ventilation systems were non-functional in the building and, according to Caroline Duchaine, bioaerosol specialist at Laval University, “the lack of ventilation has undoubtedly allowed the virus to accumulate in the air and settle in places far from infected patients.”

What we know about Corona virus transmission routes

Current data suggest that transmission via air can happen in two ways:

  1. Close contact transmission through large droplets (> 10 microns), which are released and fall to surfaces not further than about 1-2 m from the infected person.
  2. Airborne transmission through small particles (< 5 microns), which may stay airborne for longer periods and can be transported long distances. This transmission route is not confirmed by WHO, but based on the precautionary principle, this should be taken into account to manage the ventilation in buildings. 

This mechanism implies that keeping 1-2 m distance from infected persons might not be enough and increasing the ventilation is useful because of removal of more particles.

Current Recommendations to limit airborne transmission

When there is no HVAC in place

Following WHO (World Health Organisation) recommendations, it is important to open windows and doors in closed environments (schools, office buildings, etc.) in order to make sure the venue is well ventilated.

When there is HVAC system in place

Following recommendations of the REHVA (Federation of European Heating, Ventilation and Air Conditioning Associations), in buildings with mechanical ventilation systems, extended operation times are necessary in order to remove virus particles out of the building and to remove released virus particles from surfaces. It is therefore advised to start ventilation a couple of hours earlier and switch off later than usual, or to keep the ventilation on 24/7, possibly with lowered (but not switched off) ventilation rates when people are absent.

In Practice: how to monitor indoor air quality in real time?

In order to be able to follow current recommendations, it is important to be able to monitor air quality parameters remotely. In practice, what do you need to do?

During the webinar, three experts will share with you the best practices to put in place, based on current scientific knowledge. In practice, you will learn how to:

  1. collect indoor air quality data automatically
  2. analyse indoor air quality through remote visualisation tools
  3. detect deviations from thresholds in real time by setting-up alerts that alert you when ventilation is needed

Certificati bianchi: perché ti serve un energy management software e come recuperare l’investimento.

Dotarsi di un software di monitoraggio energetico, efficientare i propri sistemi aziendali ed essere ricompensati per farlo. Potrebbe sembrare troppo perfetto per essere vero, invece questo è il modo in cui funzionano i certificati bianchi. L’unica cosa che viene richiesta, al di là del raggiungimento di reali risparmi energetici, è che questi siano misurati. Azione banale? Azione complessa? Vediamolo.

IPMVP®: la tua garanzia di misurazione e verifica dei progetti aziendali di efficientamento energetico

Investire budget e risorse in un progetto è una decisione che si lega ad un aspetto fondamentale: il ROI. Gli imprenditori, anche nell’ambito della riqualificazione energetica delle proprie aziende, si chiedono:”Quale sarà il mio ritorno su questo investimento?“. L’unico modo per averne certezza è utilizzare strumenti di previsione e monitoraggio che rispettino il protocollo IPMVP®.

EPC: come i fornitori possono dimostrare i reali risparmi al cliente.

Energy Performance Contract, un contratto vantaggioso ma con un punto molto delicato: il calcolo del canone che spetta al fornitore. Strettamente correlato al risparmio che il fornitore è stato in grado di far conseguire all’azienda cliente, l’entità del canone non è sempre di facile dimostrazione. In questo articolo parliamo di come un EGE o Esco possono provare il valore della propria consulenza, svelandovi però già un punto importante: è necessario l’uso di un software certificato per il protocollo IPMVP®.

CO2 and energy efficiency : what is the scenario?

CO2= P (people) x S (services per person) x E (energy per service) x C (CO2 per unit energy). This equation is probably not new to you. But what is really behind it?

Let’s have a look at the first two data of the equation, People and Services : the current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100, according to a new United Nations report. If we sum the higher life expectancy, the improved quality of life in emerging countries such as India, China, Brazil, the increase in energy demand is ineluctable. In other words, with People and Services increasing, we can expect CO2 emissions to follow the curb (source UN). Continua a leggere
