Housing-neutral renovations on the rise
WNR is a young Dutch organization that has set itself a goal of increasing the scale of social passive house renovations. WNR stands for Woonlast Neutrale Renovatie, residential cost-neutral renovation, and as the name suggests, the long-term costs for the owner / user are the key point. The target group for WNR are apartment owners' associations of mainly multi-storey residential buildings. As a link between clients, financiers, authorities and executing medium-sized companies, WNR acts as a catalyst for integrated, very energy-efficient building renovation.
The basic ingredients in the WNR business model (incidentally without the pursuit of profit) are the long-term performance of the energetically refurbished buildings and a carefully exercised quality assurance. These pave the way for low-interest loans, long-term and with a very low repayment rate. In the end, this leads to permanently affordable, comfortable living space.
Groundbreaking feasibility study
In this lecture, Carl-Peter Goossen will shed light on the financial side of the WNR model using practical examples. Same costs for residents - before and after. Can we actually do it? And how does it pay off? Let it be made clear: it doesn't work without passive house technology. And not even without a reasonable maintenance plan.
In the WNR feasibility study, the renovation measures are geared towards the financing option, energy cost savings and planned and advanced maintenance measures. All of this is converted into monthly costs per household. In this approach, the aim is not the lowest possible investment costs, but the lowest long-term costs for the residents. For this purpose, WNR is also building a fundamentally different contract structure with the construction company. The UAVgc contract creates freedom of choice as to which (energetic) measures are taken. The investment costs are secondary, only the constant housing costs are determined by the contract.
In the course of maintenance
We will also go into more detail about an important aspect for the chances of success of all financial-strategic building interventions that have to be calculated with energy cost savings: maintenance planning, more precisely the appropriate reserve build-up. In the case of apartment owners' associations, this runs through ancillary and service costs and is decisive for their cash flow. Often the short-term pursuit of the lowest possible ancillary costs (that sells better) contradicts appropriate long-term maintenance planning. For example, things often go wrong with the chosen time frame in which maintenance or replacement costs that arise later are taken along or left out.
What to do if a homeowners association has not built up enough reserves for susceptible measures? We can report from practice that even with an immediate passive house renovation, a better cash flow for the apartment owners' association can arise. And the owners are thus sustainably protected from drastic cost increases.
About the Speaker
Trained as a structural engineer and architect, Carl-Peter Goossen is engaged in innovation in energy-efficient building construction. He is the Director and Designmanager at Bouwnext, a Chairman at association DNA in de Bouw, and is the founder father of the foundation Woonlasten Neutraal Renoveren.
We provide integrated design and development, that is the new way of working that delivers the most suitable physical, sustainable, social and economic solutions. This provides more and creative solutions and makes better-considered choices possible. Climate change requires a change in thinking. It is no longer about the investment but about the total costs of ownership. Together we therefore create buildings that meet the construction requirements, in less time, with fewer errors and with fewer costs over the entire duration.
